Product introduction

Double Roll Crusher, a kind of mining machinery, is also called double roll crusher. Mainly used for crushing ore. This machine has the advantages of small size, large crushing ratio (5-8), low noise, simple structure, and convenient maintenance. It is suitable for coal, metallurgy, mining, chemical industry, building materials and other industries, and it is more suitable for crushing raw coal (including gangue) in large coal mines or coal preparation plants. The toothed roller crusher has a large crushing capacity, and the motor and the reducer are connected by a distance-limited hydraulic coupling to prevent power overload and sensor overload protection, which is safe and reliable. The gear roller spacing is adjusted hydraulically, and the gear roller bearings are lubricated centrally. Optimal design of tooth shape, selective crushing by tension and shear force, high efficiency and low consumption, and uniform grain output.

A roller crusher that crushes materials by two counter-rotating rollers. It is composed of motor, bracket, fixed roller, movable roller and safety spring etc. Most of the roller surfaces are smooth, and the bearings of the movable rollers can move along the frame, and are supported by strong safety springs. When encountering particularly hard objects falling into them, the bearings can be removed and the objects can be spit out. Before normal operation, spacers should be used to adjust the gap between the two rollers to ensure the crushing ratio. It is suitable for crushing sticky stones.

working principle

1. This series of double-roll crushers is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices.

2. Adjustment of discharge granularity: a wedge or gasket adjustment device is installed between the two rollers, and an adjustment bolt is installed on the top of the wedge device. When the adjustment bolt pulls up the wedge, the wedge pushes the movable roller away from the The fixed wheel, that is, the gap between the two rollers becomes larger, and the discharge granularity becomes larger. When the wedge is down, the movable roller is under the action of the compression spring, and the gap between the two wheels becomes smaller, and the discharge particle size becomes smaller. The gasket device adjusts the size of the discharge particle size by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge particle size becomes smaller. .

3. The driving mechanism is composed of two electric motors, which are driven by V-belts to the sheaves to drag the rollers, and move and rotate in relative directions. When crushing materials, the materials pass through the rollers from the feed port, and are crushed by rolling, and the crushed finished products are discharged from the bottom frame.

4. For safety, the transmission part should be installed with a safety cover according to the actual situation.

Each roller of the double-roll crusher is driven by a separate motor. Also have to use a motor to drive the stick of fixed bearing through belt drive, the other end of the roller shaft of fixed bearing is equipped with gear, drives movable stick by gear. Due to the change of material properties, the movable stick moves left and right, so the tooth height of the gear must be increased to prevent the meshing and disengagement. Therefore, traditional double-roll crushers are driven by long-toothed gears, which allow the center distance between the two rollers to be changed during operation without breaking the meshing characteristics.

The working surface of the roller depends on the requirements of use, and can be selected from smooth surface, tooth surface or groove surface. For crushing hard and abrasive materials, smooth rollers can be used. Because the crushing effect of the smooth roller on the material is mainly crushing and grinding, it is mainly suitable for medium and fine crushing of medium-hard materials.

The working principle of the roller crusher

In order to obtain products with different particle sizes, the size of the discharge port of the roller crusher must be adjustable. In order to prevent the crusher from being damaged by excessive iron, it must be equipped with a safety device. The movable roller shaft of the roller crusher is supported by spring pressure. Under normal working conditions, the spring force is sufficient to overcome the crushing force required for crushing materials. Gaskets of different thicknesses are placed between the frame and the movable bearing, and the width of the discharge opening between the two rollers can be adjusted by changing the number of gaskets to meet the requirements of different product sizes. When unbroken materials enter the crushing cavity, the spring is compressed , the movable roller retreats to increase the discharge opening, and after the material is discharged, the movable roller resets under the pressure of the spring. This is the mechanical discharge opening adjustment and overload protection device (safety device).
