【Introduction】: The roll crusher used in metallurgy, building materials, refractories and other industrial sectors crushing, high hardness materials. Note: 2PG700 × 400 Type Double-roll crusher for river gravel sand best.

This series crusher is developed by our company for coarse crushing equipment crushing the roll crusher is widely used in metallurgy, building materials, refractories and other industrial sectors crushing, high hardness materials. With low noise, less dust, reliable performance, easy maintenance features.

Note: 2PG700 × 400 Type Double-roll crusher for river gravel sand best.

The main structure of the gear transmission with a fixed roller, active roll shaft, the body, chassis, cover, long gear housing and other components, the machine is powered by a V-belt pulleys on the motor outgoing, and then through a pair of intermediate gear gear rotates the fixing roller, and then the other end of the roll by means of fixing a pair of long pinions, driving the movable roller, a relative movement of the two rolls and extruded materials.

The particle size of the adjustment: two rolls with wedges or shims between the adjusting device, wedge device with the top adjustment bolt, when adjusting bolt to pull up when the wedge, wedge away from the top of the active fixed wheel roller that two roller gap becomes larger, the particle size becomes larger, when the wedge down, activity roller compression spring under the action of two gap becomes smaller, the particle size becomes smaller. Spacer device is a quantity or thickness of shims to adjust the size of the particle size, while increasing gasket two roller gap becomes larger, while reducing gasket two roller gap becomes smaller, the particle size becomes smaller .
