1. Hongrun four-roller crusher mainly composed by roller, supporting roller bearings, compaction and adjusting device, machines and drives components. Two crushing roller respectively by key fixed axis in two axis of the ends for group bearing support, and installed in chassis.
2. Active roller bolted on chassis, driven roller is equipped with safety spring and activities bearing. Is in regulating the roller clearance or when the roller between fall into metal inclusions, driven roller axle can lateral movement, and avoid damage on the machine parts.
3. Machine drive respectively by means of single or two motor, pass the triangle belt to slot wheel drag the roller, according to the relative rotation direction so as to broken material work, material from incoming mouth through the roller, the roller grinding extrusion and broken, crushing of finished below from chassis after discharge.
With the special construction features, broken ability, motors and reducer with limited distance between type hydraulic coupling ware connection, prevent power overload, sensor overload protection, safe and reliable. Teeth roll spacing hydraulic adjustment, teeth roll bearing concentrated lubrication. Tooth shape optimization design, pull shear choice and broken, high efficiency and low energy consumption, a grain of uniform. Hongrun four-roller crusher apply to coal, metallurgy, mine, chemical industry, building materials industries more suitable for large-scale coal or coal gangue) raw coal (including the breakage).
