Double roller crusher is also known as the roller sand making machine and the double roller sand making machine. Because it mainly uses the relative rotating motion of the two rollers to crush the materials for medium crushing and fine crushing, the equipment structure is simple and reasonable, the operation cost is low, and the cost is fast. It is widely used in the medium crushing and fine crushing of the ores and rocks below medium hardness in the sand making, coal mining, cement, metallurgy, chemical industry, building materials and other industrial sectors.
advantage Durable and sturdy, with low energy consumption
Applicable materials：River pebble, gangue, limestone, cobblestone, coal, dolomite, weathered rock and other medium and high hardness materials

The main structure includes motor wheel, motor, belt, flywheel, bearing seat, rotor, buffer spring, frame, shell, roller body, horizontal support, etc., covers a small area, lighter weight, more conducive to the operation and maintenance of operators.
When the material enters the crushing chamber of the machine, it is forced through the two rolls by the biting force of the rotating roller, and at the same time, it is squeezed and shear ground by the roller, and the material begins to crumble. The small particles after fragmentation are thrown down the machine along the tangent line of the rotation of the roller through the gap between the two rollers. The large particles exceeding the gap are further broken into small particles and discharged.
