According to the crushing force mode, the crusher machine divides into stone crushers and grinding machine.Whats the difference between stone crusher and grinding mill?General speaking, the former one is used to reduce the larger slab into a smaller size, various models of crusher are designed to maximize productivity at the lowest cost. The configuration of the suited crush machine is varied with different crushing stages in the complete crushing circuit, coarse crushing, medium-sized crushing, and fine crushing. The latter one of grinding mill machines are preferred to process fine and extremely fine material, grinding mediums include steel ball, steel rod, gravel, and metal lump so on. Some equipment is capable of crushing and grinding, such as self mill.Discrimination of the working principle1 Jaw Crusher. The movable jaw plate continually presses against the fixed die at a set time and force to squeeze the rock material caught in it.2 Cone Crusher. The inner movable cone rotates eccentricity and bumps the outer fixed cone, thus exerting strong crushing force on the ore material.3 Roll Crusher. The ore material is subjected to continuous crushing and impacting force between the two rollers.4 Impact Crusher. The ore lump crushed by the impact force of rapidly rotating moving parts.5 Ore Grinding Machine. The ore slab is crushed by the impact and grinding force of the grinding medium (steel ball, bar, gravel or lump) in the rotating cylinder. Rod mill, pan mill, ball mill, vibration mill, centrifugal mill, etc.Each kind of crusher has various models to suit different applications. Jaw crusher has the features of large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance and economical operation cost. PF-I series impact crusher can crush materials with length less than 100 ~ 500 mm and its compressive strength can reach up to 350 MPA, which has the advantages of large crushing ratio. It is suitable for crushing medium hard materials, such as limestone in cement plant.
1 Adjustable fine crusherThe adjustable fine crusher mainly consists of a rotary part, guard plate, crushing chamber. The latest fine crusher equipped with a hydraulic device can be very convenient to maintain, save time cost.2 Jaw crushing typeJaw crusher, is the first choice for primary crushing equipment, with large crushing ratio, uniform product size, simple structure, the relatively small volume can be installed in the tiny space, etc. Therefore, it is widely used in mines, metallurgy, construction material, water conservancy and chemical industries.Compared with cone crusher, jaw type crusher has less investment, less finished flake and lower production cost. Compared with hammer crusher, the wear resistant parts have longer service time, high production efficiency and fewer maintain fees.The common jaw crusher has single toggle type and double toggle type, the former one also called as simple swing crusher, the latter one is called as complex swing crusher.3. Gyratory crusherThe gyratory crusher is a large scale crushing machine which uses the gyratory movement of the crushing cone in the crushing cavity to extrude, squeeze and bend the materials. When the shaft sleeve rotates, the crushing cone is moving in eccentric around the center line of the machine continuously. The productivity of gyratory crusher is higher than that of jaw crusher.There are two types of discharging material and overload insurance, one is mechanical type, by adjusting the nuts on the top of the main shaft to lift up or down the crushing cone, thus change the discharge outlet width, and by cutting the safety pin on the driving pulley to stop overload. Another way is hydraulic gyratory crusher type, by changing the plunger under the hydraulic oil volume can adjust the crushing cone position, thus changing the size of the discharge port.4 Cone crusherCone crusher widely used in the metal and mon-metal mines, cement, sand & gravel, aggregate, quarry, metallurgy and other industries. it is suited for fine crushing all kinds of ores and rocks with hardness 5 ~ 16, such as iron ore, Non-ferrous metal ore, granite, limestone, quartzite, sandstone, cobblestone, etc.The working principle of cone crusher is the same as that of gyratory crusher, but it is only suitable for medium-sized crushing or fine crushing. The requirements of uniformity of particle size distribution in medium and fine crushing operations are generally higher than that in the coarse crushing operation. Therefore, a section of the parallel zone should be set at the lower part of the crushing cavity. In addition, the rotating speed of the crushing cone should be accelerated so that the material can be squeezed more than once in the parallel zone.The crushing of fine crushing operation is larger than that of coarse crushing operation, so the loose volume after crushing increases greatly. In order to prevent the crushing chamber from blocking, the total discharging cross section must be increased by increasing the diameter of the lower part of the crushing cone without increasing the discharging opening to ensure the required discharging granularity.When the Simon Spring Safety cone crusher overloads, the cone-shaped Shell forces the spring to compress and raise itself in order to enlarge the discharge port and discharge the non-broken material. The adjustment of the discharge opening is carried out by the adjusting cover, and the adjusting cover fixed with the shell can be rotated to drive the shell up or down by the thread on the outer circle, so as to change the size of the discharge opening. The safety and adjustment mode of hydraulic cone crusher is the same as that of hydraulic gyratory crusher.Maintenance of cone crusher1, Ensure full load production, avoid too coarse product granularity.2, Optimize the cone crusher productivity by setting reasonable crushing ratio.3, It is necessary that equipped with an iron removal device.4, The spring cannot be too heavy pressured, the large pressure may occur shaft broke, light pressure may cause spring vibrating, influence the crushing efficiency.
Right way. First of all, you need to know the crusher materials, the maximum feeding size, finished particle size, handling capacity, crushing environment. With detailed information, JXSC will provide the stone crusher suitable for your production needs.
The humidity and hardness of different materials are different. The higher the hardness, the higher the degree of difficulty. For example, granite hardness, the jaw crusher, cone crusher, impact crusher will better. River pebble texture hard wear-resistant, roller crusher crushing effect is better. Brittle materials are more suitable for heavy hammer crushers, such as calcite.
2. Sorting machineWe can design the crushing plant flow chart when knowing the crushing demand and determine the primary, secondary and tertiary crusher use of which type. crusher. The next step is to choose the type of device. In order to improve efficiency, the general primary crusher processing capacity will be larger than the secondary.
1. Control material sizeThe crusher has a maximum feed size. When the feed particle size is too large to the equipment caused serious damage. Whether soft or medium-hard material, both cause different damage. If some of the materials are larger than the maximum feeding size of the crusher, the crusher is easy to appear stuck cavity, blocking phenomenon, affecting the aggregate production efficiency. 2. Correct feeding materialMany enterprises in order to increase the production capacity and blindly carry out the transformation of the bunker. It resulted in excessive feeding. And that feed too much, it will cause the material too late to break, and the broken material can not be discharged in time, resulting in blocking. Therefore, material cut-off and excessive feeding will affect the capacity of the crusher. 3. Maintenance and repairsThe daily maintenance and repair of the stone crusher is the key to the effective operation of the equipment. Check the machine regularly and replace the wear-out parts in time.

In order to crush rocks and extract gold, you will need the right equipment that can achieve this quickly and efficiently. That being said, utilizing rock crushers will help prevent you from missing the opportunity of hitting paydirt. Portable rock crushers will change the way you prospect for gold and with several options available, making sure that you select the correct product will be invaluable.
The term itself is pretty self-explanatory. These machines are designed to crush any type of stone from quartz to limestone and everything in between. How much is able to be processed per hour will depend on the model you purchase.
The intention of small rock crushers, such as those we have here at Kellyco, is to allow you to extract more gold instead of leaving any paydirt behind. The amount of gold that can be contained within rocks in areas you didnt know were there may surprise you. However, without a rock crusher in your arsenal, you will never be aware of what was left behind.
Portable rock crushers use a very simple approach, power. With various sized engines available depending on the model, these machines are designed to take small rocks and, thanks to a huge amount of pressure and power, crush them down and allow you to process them through your sluice box.
The aim of any small rock crusher for sale is to be able to break that rock down into a fine powder. In doing so, it will be able to pass through a classifier before going through the sluice box and any gold can then be separated. Even relatively small pieces of rock that are left intact could lead to you missing out on some gold, and when you know you have hit paydirt then you hardly want to leave anything behind.
Most models, including the Keene G-Force rock crusher, will use a hopper box with gravity to move the rocks through the crusher. The rock is fed into the hopper box and then moves into the central compartment of the crusher. A huge amount of force effectively smashes the rock at high speed and the greater the force then the finer the powder. With that in mind, the power of the engine contained within the rock crusher will be important.
With several options available, knowing which are the best rock crushers for sale will make your job of identifying the right product for you easier. Of course, budget may play a part but Kellyco does have a number of small portable rock crushers for sale across a wide price range.
There are several key points to consider when looking at purchasing a portable rock crusher. First, there is the volume of rock that can process for up to an hour. With some capable of producing over 2 tons of powder, also known as grind, this should be more than adequate for the majority of treasure hunters.
Another point to remember is the size of rock that the crusher can handle. These kinds of rock crushers for sale are not designed to take large boulders and break them down on an industrial scale. Instead, we are talking about rocks that are around one inch in size that can be effectively smashed in seconds. Once again, we recommend that you check the maximum size that the model you are looking at can take before making your purchase.
The best rock crushers for sale will contain a large hopper box, be capable of crushing a substantial amount of rock in one hour, and break things down into an easy to manage powder. As long as those points are met, then you should not have any problem extracting as much gold as possible from your expedition.
There are several additional features that deserve to be mentioned with a rock crusher. For example, you need to examine how a particular model is powered. With both gas and electric available as options, it should be easy for you to get things started. As a side-note, the gas version is often regarded as being cheaper to operate. Also, we have to think about transportation. These machines are not the lightest around which is why there are lighter models, such as the Keene trailer mounted crusher, on the market. This does make it easier to get to those more remote areas that you may wish to venture to on your expeditions.
You may wish to consider looking at the process that the rock crusher uses in order to deliver the powder. Different models may put the rock through various processes with each stage resulting in something even finer than before.
Finally, there has to be the question of replacing parts even when you are out there in the wild. Cleaning the machine and clearing it of debris is important or it may result in becoming clogged. However, models that have been manufactured by Keene will all be easy to adjust and maintain so this shouldnt be a problem.

Do you need to process sand, gravel, minerals, rock, or other aggregate products and have not yet purchased or leased crushing equipment? Theres no questionyou need to work with a capable and professional material handling equipment design and engineering company dedicated to selling, renting, and installing the best new crushers for your needs.
However, if youre new to the aggregate processing industry, you probably have a lot of questions about rock crushers. As foundational material handling equipment in all plants, crushers need to coordinate seamlessly with screens, conveyor systems, and washing equipment.
It is common to use multiple crusher types within a project and set them up as stations in a circuit format to perform the necessary material reduction work. In many cases, primary, secondary, and tertiary, and quaternary stations are installed to reduce the rock to the desired size, shape, and consistency.
For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to threeor even fourstations with a variety of crusher types.
As the first stage in a crushing circuit following extraction from a mine site, (or in the case of recycled asphalt production, delivery to the RAP processing plant via truck transport), primary crushing reduces material to a size and shape that can be handled by the secondary crusher.
Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types.
In secondary crushing, reduction ratios become an essential consideration. Knowing just how fine you need your final output to be, along with the feed requirements of your tertiary or final reduction crushing station, will help you determine how much reduction needs to take place within this stage.
Cone crushers are often placed within the secondary crushing station because they are versatile in terms of feed, closed side setting, speed, and throw. With cone crushers, though, it is essential to operate them at consistent choked settings to keep productivity up.
The goal of the tertiary (third), quaternary (fourth) or final reduction stage of the crushing process is to size and shape rock or other material into a marketable product. Again, there may be overlap between stages in terms of which crusher styles work best.
Sandstone, limestone, gravel, and granite are arguably the most common aggregates used in the construction industry today, but these rocks have very different hardness and abrasiveness characteristics.
The answer might be three to four if youre talking about setting up stations in a complete rock crushing plant. Those are the primary, secondary, and tertiary/quaternary/final reduction rock crushers, which we covered above.
Of course, there are also different styles of rock crushers. Compression-style jaw and cone crushers, for example, fit into the various stations in a crushing circuit (depending on factors like the sizes, varieties, and hardness of the rock you need to crush, as well as the necessary output).
The number of crusher types in terms of style and configuration can be more challenging to quantify, as there are lots of ways to customize rock crushers. However, youll find four basic designscone, jaw, gyratory, and impact crushersoperating within many crushing plants.
Jaw crushers are also known as rock breakers and are used to break up larger, harder materials into more manageable pieces. They tend to do well with many different types of materials and dont display as much wear and tear as impact-style rock crushers. They also produce minimal fine materials and dust, though the finished product with this type of rock crusher almost always requires secondary crushing.
To learn more about jaw crushers, youll want to catch our previous blog post all about these tough pieces of material handling equipment and the most common questions operators have about jaw crushers.
Cone crushers can accept medium-hard to very hard and abrasive feeds that might be dry or wet, though not sticky (whereas gyratory crushers are better at handling softer, dryer feeds). Their output will be a relatively cubical product, with a reduction ratio of about 6-to-1 through 4-to-1.
Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles.
Some operations also use impact-style crushers after they have already used a different type of rock crusher that produces a more elongated stone. This helps further shape the crushed material into a finer consistency with a more cubical nature.
Impact crushers tend to be less expensive than compression crushers (aka cone and jaw crushers, which we already covered) and have a higher reduction ratio. They can also break sedimentary deposit-type rockslimestone and similaralong natural lines, which rounds off sharp angles and weak edges. This can produce a result that is more sand-like in nature.
Drawbacks of impact crushers include their tendency to produce an excess of fine materials if used with softer rocks. Impact rock crushers can also require frequent part changes and can create a large amount of dust that can be an issue on some worksites.
Stationary plants have long been preferred because they feature a higher capacity and efficiency and lower production costs with easier maintenance. They also have historically featured a lower energy cost if you have on-site electricity, and no additional equipment is needed to move them from place to place.
Its true that portable material handling equipment already offers unmatched production flexibility. For instance, if you need to move your crushing plant more than once a year to multiple job sites, you are likely better off investing in portable equipment.
These self-contained plants are better suited to smaller projects and can be moved from project to project as necessary. They are often still not quite as efficient and have less capacity than stationary plants, but they can be more cost-effective in the long run if you have multiple projects in different areas.
