Introduction to Roll Crusher

The roller crusher appeared in 1806 and has a history of over two hundred years. There is a saying that goes: 'The survival of the fittest is determined by natural selection.'. After more than 200 years of development, the roller crusher can still be used by people without being eliminated, which shows its value. The roller crusher is suitable for fine crushing operations with feed particle size less than 80mm and finished product particle size requirements of 50-20mm. Its excellent fine crushing effect is incomparable to any other crusher. So, the roller crusher still has a certain influence in the crushing industry. After more than two hundred years of development, the roller crusher is no longer the bulky and uneven crushing fineness crusher it used to be. After multiple technological innovations and structural modifications, the roller crusher has finer crushing particle size, greater processing capacity, simple operation, wide applicability, and long service life,Adjustable discharge particle sizeIt has been unanimously recognized and favored by a large number of customers.
The twin roll crusher, also known as the double roll crusher or twin roll crusher, has been manufactured by Hongtong Machinery for 30 years. It has excellent appearance and performance in the production of twin roll crushers. This machine is mainly suitable for crushing medium hardness materials such as slag, coke, limestone, coal, steel slag, etc. in industrial sectors such as chemical, power, cement, metallurgy, building materials, refractory materials, etc.
The 2pg roller crusher can also be called a roller crusher, double roller crusher, or roller crusher. It is a mechanical device that uses the frictional force of the roller surface to bite the material into the crushing zone, causing it to withstand compression or splitting and be crushed. Mainly used for fine crushing of materials. When used for coarse crushing or when increasing the crushing ratio, teeth or grooves are often made on the roller surface to increase the splitting effect. This type of crusher is called a double toothed roller crusher. When finer finished products, higher output, and larger crushing ratios are required, a four roll crusher is needed.

Suitable materials for roller crusher

River pebbles, calcite, quartz, marble, pebbles, bentonite, iron ore, bluestone, mountain stones, water slag, limestone, weathered sand, diabase, granite, basalt, etc.

Working principle of roller crusher

This series of roller crushers mainly consists of rollers, roller support bearings, clamping and adjusting devices, and driving devices. Adjustment of discharge particle size: A wedge-shaped or shim adjustment device is installed between the two rollers, and the top of the wedge-shaped device is equipped with an adjustment bolt. When the adjustment bolt pulls up the wedge block, the wedge block pushes the movable roller wheel away from the fixed wheel, that is, the gap between the two rollers increases, and the discharge particle size increases. When the wedge block is lowered, the gap between the two rollers of the movable roller wheel decreases under the action of the compression spring, and the discharge particle size decreases. The gasket device adjusts the particle size of the discharge by increasing or decreasing the number or thickness of gaskets. When adding gaskets, the gap between the two rollers increases, and when reducing gaskets, the gap between the two rollers decreases, resulting in a smaller discharge particle size. The driving mechanism is composed of two electric motors, which are transmitted to the pulley through a V-belt to drag the rollers and rotate them in opposite directions. When crushing materials, the materials are crushed through rollers from the feeding port, and the crushed products are discharged from under the chassis. For safety reasons, the transmission part should be equipped with a safety cover according to the actual situation.
