Crusher

How It Works

Heavy-duty Double-roll Crusher

The crusher adopts both shearing and tensile crushing principles, with double motors driving the rollers slowly through a hard-tooth-surface gear reducer, ensuring stable operation, low noise, and minimal over-crushing. The roller gap can be adjusted manually or electrically via a hydraulic system, and a check-back device keeps the gap constant for uniform discharge granularity. Controlled by PLC, the crusher enables fully automated crushing, feeding, and discharging processes. Its modular design allows reducers and gear plates to be swapped between rollers, improving equipment compatibility, while the centralized lubrication system with positive-pressure grease sealing reduces labor intensity and enhances bearing reliability.

Energy-Efficient Double-roll Crusher

Based on the principles of momentum conservation and mechanical energy conversion,our crusher is equipped with a flywheel energy storage system that stores and releases kinetic energy.This increases the rotational inertia of the toothed rollers, reducing operating current.The technology is particularly effective for crushing raw coal with uneven particle sizes and variable properties, ensuring stable and energy-efficient operation.

Applications
