Double Roller Crushers are Roller Crushers that are widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as sandstone, ore, coke, lump coal, mineral slag, cement clinker, fireproof materials, and so on.
Double roll crusher with a pair of opposite rotating rolls round, multi-roller crusher, two pair or several pairs of opposite rotation of the round roll. Single roller crusher roller length is generally less than the diameter for the primary crushing.
Double roll crusher is driven by the motor through the pulley or gear shaft opposite two rollers rotate, or were driven by two motors rotate two rollers. Double roll crusher with material by weight and the friction between the roll surface into the crusher and discharge within the broken. Through changes in two double roll crusher roller bearing pads between the number, or the use of worm gear to adjust the mechanical adjustment between the two rollers the force generated to maintain the discharge opening gap.
Double roll crusher spring is the insurance unit. When a hard material or transport of bulk materials cannot be broken fall into the crushing chamber, the roll of the force increases, the movable roll can be left by the movable bearing compression spring, increasing the gap between two roll to discharge a hard object, and then by the spring restoring force to the movable Roll back to the original position. Double roll crusher movable roll can be used to replace the broken boards.
1. Compact structure, low noise and efficient; 2. Easy to install and only need simple foundation; 3. Pressure adjustment and discharge size control; 4. Self-protection; 5. Low cost maintenance and easy maintenance.
