rock crushers at kellyco | gold prospecting equipment

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.

If rock crushers are something of interest to you, but you are unsure of what to do next, then feel free to reach out to our customer service team. Contact us directly via our customer care department and our team of expert gold prospectors will be able to advise you on the best rock crusher for your needs and answer any questions that you may have.

An Easier Way to Crush Rocks! Once primarily used by landscapers and contractors to crush rock for demolition, gold miners are now using them to both test material in the field, and recover gold back at home. In most cases, you can take your rock crusher straight from the shipping container and use it in less than half an hour. No wasted time trying to find the right pulleys or chains. Whether you need a manual rock crusher or a motorized version, you get everything you need to start crushing / pulverizing rock and getting the gold right away! A rock crusher can be an invaluable tool if it has been designed and built by miners for miners just like you'll find below. Tough machines built well and rigorously tested in the field means less work for you. Warranted by the manufacturers.

During the rush to the gold fields of the 1800s, a LOT of gold was removed from the rivers and banks of the Western US and Alaska. The old-timers used very ineffective methods, but a lot of gold was taken out of the streams and banks. That gold had been setting there for hundreds if not thousands of years. It takes time for the waterways and banks to "replenish" the gold that is recovered by miners. Mother Nature helps every year through floods and snowmelt.

Keep in mind that all the gold in any river came from "above" -- from the veins and outcrops that push up through the hillside and slowly, due to weathering (freezing and thawing, wind and rain) a chunk of gold bearing quartz is eventually broken off and tumbles downhill until it finds its way into the river where it is warn and shaped even more by the action of the water, sand, etc. Every time gold moves in the river, it goes deeper down, until it hits bedrock, and there the gold sits until it is found.

Over millions of years, the Earth has gone through many changes. Sometimes, a river that is laden in gold will be thrust up and dry out. That is why you may find placer gold high up in an exposed rock bed with obvious water-warn rock. Sometimes the river changes courses, and new rivers cut across the old channels. No matter how things change, the fact remains that the gold came from a vein, which eventually became an outcrop. Knowing this, many modern-day prospectors are switching from working barren streams to hard rock, and hunting for those outcrops with could lead to a very valuable vein. Even if you do not work it yourself, you may have a good discovery which could mean another person or company will buy or lease your find!

Rocks are rocks, unless they contain valuable minerals, metals, or elements. When a rock has values in it, it's then called ore. In order to liberate the minerals, it needs to be crushed down. In days of yore, a stamp mill was the primary form of crushing rock, but in the modern world, there are jaw crushers, impact mills and gyrator crushers, as well as ball mills. They all have their own pros and cons -- and price tags. Crushers take larger rock and break them down to smaller rocks, and then they are processed through an impact mill to reduce the ores to a finer particle. If the ore needs to be smaller yet, it's placed in a ball mill to reduce the materials to a slurry that has the consistency of muddy water.

Some mining companies have very large equipment, which can handle hundreds of tons or rock an hour. These businesses can effectively go after ores of lower grade materials because of the high volume they can process. For the average prospector, though, it's not feasible to crush down a ton of ore for only a few grams of gold. The average miner can instead purchase a CrazyCrusher manual rock crusher or an electric or gas powered rock crusher and get the gold out in smaller batches. Crushing rock to recover gold can be easier, faster, and much more profitable than prospecting in over-worked streams and rivers. With prices starting at less than $500 for a manual crusher, you may want to consider this time-saving method for getting the gold!

rock crushers

The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.

Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.

In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.

All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.

Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.
