The types of pressure crushers include jaw crusher, roller crusher, and gyratory crusher. The pressure type crusher uses two hard parts of the machine to press each other to crush rock material. For example, the jaw crushers use the fixed jaw plant and movable jaw plate.

The jaw crusher's main function is to reduce the size of the raw materials or large pieces of material to a sufficiently small size, so as to facilitate the next step of the crushed material. In the quarries and mine materials crushing plant, it is generally used as a primary crusher. The types of jaw crushers are single toggle and double toggle. The construction of the single toggle jaw crusher is compact and simple, and the transmission components such as eccentric shafts are less stressed. Due to the vertical displacement of the movable jaw is small, the material is less excessively broken during processing. Therefore, the wear of the movable jaw plate is less.

Compared with the simple pendulum type, the double toggle type jaw crusher has the advantages of lighter weight, fewer components, a more compact structure and uniform crushing, high productivity. 20-30% higher productivity than a simple swing jaw crusher of the same specification.

Tooth Roller crusher is a new product that is designed and developed according to the structure principle of Gunlock crusher in America. The machine has the advantages of small volume, high crushing ratio (5-8) , low noise, simple structure, convenient maintenance, high productivity, even particle size of crushed materials, low over crushing rate, convenient maintenance, etc. The mall roller crusher is widely used in the mining industry as a secondary crusher.

Gyratory crusher is a new type of crusher that can replace fine jaw crusher and cone crusher. It consists of a concave surface and a conical head, both of which are usually lined with manganese steel. The inner cone has a slight circular movement but doesn't rotate. The gyratory has the advantages of good finely crushing effect, large processing capacity, small vibration, simple maintenance, low cost, and less lining plate wear.

Impact crushers crush materials by impact rather than by pressure. The material is broken in the crushing chamber under the impact force. It can handle materials with side length less than 100-500 mm, with compressive strength up to 350 MPA. It has the advantages of a large crushing ratio and cubic particles after crushing. There are two types of impact crushers: Horizontal Shaft Impact(HSI) Crushers and Vertical Shaft Impact(VSI) Crushers.

In the sand making plant is one of the essential crushers. Cone crusher according to the crushing force is divided into Simmons spring type and hydraulic type. Hydraulic type is divided into single-cylinder and multi-cylinder cone crusher. According to the rotary speed, there are three types: low speed, medium speed and high speed.

The basic structure of cone crusher is similar to that of rotary crusher, but the range is larger. It rotates and presses against the stone on the side of the machine, where it falls into the lower chamber and is crushed again until it falls out of the bottom. Its advantages: reliable structure, high productivity, easy adjustment, and low operation cost.

Hammer crusher(Hammer mill) is broken by an impact between a high-speed hammer and material. This type of crusher is divided into two types: single rotor and double rotor. Single Rotor is divided into reversible and irreversible. Hammer crusher is mainly composed of the rotor, spindle, hammerhead, lining plate and impact plate. And it mainly crushing for coal, salt, chalk, gypsum, brick, limestone and so on. It also used for crushing fiber structure, flexibility, and toughness of strong broken wood, paper, etc.

The advantages of the hammer: larger crushing ratio, high production capacity, uniform products, less over-powder phenomenon, simple structure, light equipment quality, simple operation, and maintenance.

Sand crusher is also called VSI crusher. It is an indispensable equipment for artificial sand manufacturing plant. VSI crusher imported advanced German technology development and production, with the international advanced level. Its performance plays an irreplaceable role in the fine crushing equipment of various materials. There are two types of sand-making machine: stone hit stone and stone hit steel.

The upper and lower hitting guard plate is installed on the crushing cavity wall of the sand making machine. It makes the ore material to be crushed by the impact, friction or high-speed impact between the material and the lining layer formed by the material and the material accelerated by the flywheel when accelerating. The materials do not come into direct contact with the equipment. This method reduces the wear and tear of fittings and prolongs the service life. "Stone hit stone" sand crusher is suitable for material with high abrasion above medium hardness, such as basalt. And the finished product has good grain shape, but the powder content is a little more. So it is more suitable for aggregate shaping.

In the crushing cavity wall of the sand-making machine, the lower hitting guard plate is replaced by the perimeter guard plate. When the ore material is thrown out by the roller, it is directly impacted on the guard plate for many times and the crusher. Under the constant impact, and then the crushing cavity material impact, ore material broken more fully, and the finished material particle size smaller. The "stone hit steel" sand crusher is suitable for small abrasive materials below medium hardness, such as limestone, and the crushing efficiency is high. However, due to crushing depends on the impact, so wear parts are higher. The finished product is slightly worse, it is more suitable for sand-making.

why put gravel on a flat roof - the purpose of gravel on rooftops - iko

A built-up roof (BUR), sometimes called a tar-and-gravel roof, is a tried-and-true style of flat roof. Here, alternating layers of roofing felt (usually fiberglass) and hot-applied asphalt are combined to create a long-lasting roof system.

A layer of gravel, or small stones, is applied on top of the final coating of asphalt to protect the roof from the elements, including ultraviolet (UV) rays and hail. The gravel is embedded into the top coat of asphalt (known as a flood coat), which helps the gravel stay in place. (Source: American Society of Home Inspectors.)

Even though the asphalt waterproofs the roof (highly important for flat roofs), the gravel provides an important, life-extending extra layer. Although commonly called gravel, the top layer is usually some sort of aggregate material (such as pea gravel, slag or mineral granules). (Source: Everybody Needs a Roof.)

BUR aggregate is usually pea-sized, about a quarter-inch thick, and is used to impart the Class A surface burning designation in accordance with mandatory requirements for ASTM E108, UL790 or CAN/ULC S107M. (Sources: Absolute Roof Solutions, WATERPROOF! Magazine.)

Modified bitumen roofs are a mix of asphalt and rubber with a layer of gravel embedded in the top layer of material during manufacture to provide UV protection. No additional gravel on the roof is required. (Source: Roofing Contractors Association of British Columbia.)

Ballast is a different style of gravel, which is applied to single-ply roofing systems. Although the primary purpose of ballast is to weigh down the roofing materials, it also offers similar protective benefits as described above.

Ballast is commonly used with roofs made of tar-and-gravel roof alternatives, including ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO) single-ply flat roofs.

Single-ply roofing materials arent self-adhered, nor are they sealed together in any way. Since nothing secures the waterproofing membrane to the roofing materials underneath, ballast is needed for weight to protect the roof from strong winds.

Ballast is different from BUR protective gravel. Ballast stones are usually one to two inches thick and applied more generously than on a built-up roof. The heavier stones provide substantial protection against wind gusts. (Source: Roofing Southwest.)

A ballast system helps cut roof system application costs, as it takes less time to install since sealing the layers together isnt necessary. Ballasted flat roofs are a popular choice, especially for commercial buildings.

stoneless corn masa mill for snack food processing | ac horn mfg

Our Stoneless Masa mill creates a new benchmark for superiority that other mills fail to meet. Instead of stone or aluminum oxide plates, its design and construction relies on proprietary Nihard alloy plates. The durability of our Nihard alloy plates allows for greater precision grinding than either stone-based mills or those using aluminum oxide plates. Stones are subject to chipping, creating an inconsistent mill surface that reduces product uniformity. Rocks, metal and foreign debris, common in masa processing, wont affect the precision performance of our Nihard alloy plates. Our system also saves you time and the expense of installing a second downstream piece of equipment for de-stoning.

Wire wrapping is a technique that involves bending wire around stone, sea glass, shells, amber, or other ornamental centerpieces to create a piece of jewelry. Wire wrapping can create beautiful rings, pendants, necklaces, and other similar kinds of adornments. What's more, when wire wrapping you don't need elaborate tools to drill and bore holes into the stone. With just a few simple tools and supplies, you could soon make your very own piece of wire wrapped jewelry!

To wire wrap a stone, start by cutting 20-gauge soft wire into 6 8-inch long pieces and taping them together at the ends. Mark the middle of the bundled wire with a marker, then wrap a 5 inch piece of binding wire around the middle mark. Next, use a penknife to bend the topmost wire into a outward-pointing V shape on either side of the center to create a cradle for the stone. Then, shape the wires around your stone and use more binding wire to bind the ends together before trimming off the excess. For tips on how to choose the right shaped stone for your centerpiece, read on! Did this summary help you?YesNo
