China Fote

With the continuous expansion of the scale of large coal mines and coal preparation plants in China, the production capacity of existing crushers cannot fully meet the demand. As a result, a large medium crusher-high-strength double-toothed roller crusher came into being. The crusher has the advantages of large production capacity, stable discharge particle size, reasonable structure and durable equipment.
Its structural analysis and machine features are as follows.
The high-strength double-tooth roller crusher is mainly composed of an electric motor, a fluid coupling, a coupling cover, a speed reducer, a body, a roller bracket, a centralized lubrication system, and an electric control system.
The electric motor is the power source of the crusher, and the crusher is driven by a dual motor. The connection between the motor and the reducer is a torque-limiting fluid coupling to reduce shock and vibration during starting and to protect against overload. The coupling cover is welded with steel plates to protect the fluid coupling. The body is the core part of the crusher. The body is equipped with a hand pressure pump and a cylinder. The oil cylinder is connected with the suspended bearing housing. The spacing between the two tooth rollers can be adjusted through the oil cylinder to meet different discharge particle size requirements.
