Application of Hydraulic Double Roller Sand Making Machine

This hydraulic double roller machine, also called twin roller crusher, is widely used in metallurgical building materials, mining, chemical industry and other industries.

Applicable Materials of Hydraulic Double Roller Sand Making Machine

Double roller sand making machine is mostly used for crushing medium-hard rocks with compressive strength of less than 200 Mpa, such as limestone phosphate, basalt, granite, river pebbles, iron ore, gold ore, copper ore lead-zinc ore, Calcite, quartzite, marble, nickel ore, asphalt, bricks, cement, and other materials.

Features of Double Roller Sand Making Machine

1. Four row cylinder roller bearing with higher capacity.

2. The roller shaft can be solid forged, or of the structure of fixed bush. The roller surface is with advanced and proven technology, long service-life, and easy maintenance.

3. The moving roller and fixed roller adopt Germany technology with self-aligning sliding, stable stress, good damping effect, and assure the stable operation.

5. Advanced intelligent lubrication system.

6. Perfect program control system and highly integrated hydraulic system.

7. The adjustable feeding system is equipped with electric actuator.

Working Principle of Double Roller Sand Making Machine

Double roller sand making machine is designed based on the principle of material bed grinding, its main characteristics are: high pressure, full speed, full material crushing. The roller crusher consists of two squeezing rollers which rotate synchronously in the opposite direction, one is the fixed roller and the other is the movable roller. The materials are fed from the top of the two rollers, which is continuously pushed to fall down between the rollers by the extrusion roller. Under the high pressure of 100-150mpa, the stones are discharged from the bottom of the roller crushing machine. The discharged materials contain a certain proportion of fine finished products. In the interior of non-finished particles, a large number of cracks are generated, which improve the material’s wearability, and greatly reduce the energy consumption of grinding in the further crushing process. The material through grinding roller is mainly divided into three stages: full material density, lamination and crushing, agglomerating and discharging stage.
