250*400 small double roller crusher | double roller crusher manufacturer | double roller crusher wholesale

Introduction to Double Roller Crusher: Double Roller Crusher is also called Roller Crusher, Double Roller Crusher and Double Roller Crusher. Counter-roller crusher (counter-roller crusher) uses two sets of independently driven rollers to crush materials using the squeezing force and grinding shear force generated by relative rotation. When the material enters the crushing chamber of the machine, it is affected by the meshing force of the rotating rollers, forcing the material to pass between the two rollers. At the same time, it is squeezed and sheared by the rollers, and the material begins to break. The small particles are thrown along the tangent of the roller rotation, through the gap between the two rollers, and thrown toward the bottom of the machine. The large particles that exceed the gap continue to be broken into small particles and discharged.
Application scope of counter-roller crusher (counter-roller crushing)
Counter-roller crusher (counter-roller crusher) can be used in industrial sectors such as mineral processing, chemical industry, cement, refractory materials, abrasives, and building materials. It is used for finely crushing ores, rocks and refractory materials with high hardness and below. Counter-roller crusher (counter-roller crusher), especially in the refractory and mining industries, has a better effect than general crushing machinery. Over the past few years, it has also been widely used in industries such as crushing steel sand
Counter-roller crusher (counter-roller crusher) Crushing) Working principle and structure
Hupo series of double-roller crushers (double-roller crushers) are mainly composed of rollers, roller supports, bearings, compression and adjustment devices, and driving devices.
To adjust the discharging granularity, a wedge-shaped or gasket adjusting device is installed between the two rollers. The top of the wedge-shaped device is equipped with an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge will push the movable roller upward. away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the discharge granularity becomes larger. When the wedge moves downward, the gap between the two rollers of the movable roller becomes smaller under the action of the compression spring, and the discharge granularity becomes smaller. The gasket device adjusts the discharge granularity by increasing or decreasing the number or thickness of the gaskets. When the gasket is added, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge granularity becomes smaller. .
The driving mechanism is composed of two electric motors, which are driven to the sheaves through a triangle belt to drag the rollers and rotate in relative directions. When crushing materials, the materials pass through the rollers from the feed inlet and are crushed after rolling. The crushed products are discharged from under the bottom frame.
For safety, the transmission part should install a safety cover according to the actual situation.
