Design Principles

​

The CLM series high-pressure roller mill is a grinding equipment designed based on the principle of bed crushing. It mainly consists of a frame, roller system, hydraulic system, feeding device, control system, and transmission system. The roller system is divided into a movable roller system and a fixed roller system. The two roller systems rotate slowly relative to each other. The movable roller system applies pressure through a hydraulic cylinder and can move horizontally on the frame guide rail, crushing the material continuously fed into the gap between the two rollers, compressing it into a cake that falls outside the machine.

Structural Features

The roller surface has a self-generated wear-resistant protective technology, forming a self-generated wear-resistant protective layer during use, resulting in a long service life for a single use. The roller surface can be maintained online with simple operation, short time, and low cost, and the roller sleeve is replaceable. The design concept of constant roller gap control within a certain pressure range and high-pressure roller load optimization control technology solves the problems of material segregation and current over-limit tripping in traditional high-pressure roller mills, improving capacity and economy while ensuring material extrusion effect. The automatic control system, based on distributed fuzzy control principles and integrated with specialized components from world-renowned suppliers, can be controlled locally or remotely from the control room, offering simplicity, stability, safety, and reliability.

Product Advantages

Increased production and reduced consumption: large crushing ratio and processing capacity, simple and quick maintenance, effectively improving output while reducing energy consumption and operating costs.

Flexible configuration: diversified product solutions, flexible process system configuration, and excellent cost performance.

Environmentally friendly and efficient: material is crushed by static pressure, equipment runs smoothly with low noise and minimal dust pollution.

Roller mill shaft

The roller press shaft is the core transmission component of the roller press, mainly used to connect the output shaft of the reducer with the roller body, transmit torque, and withstand radial and axial forces during the high-pressure extrusion process. The figure shows a solid shaft made of forged steel (keyways visible on the surface), with a diameter of approximately 500-800mm and a length of about 2-4m. It undergoes quenching and tempering treatment (HRC28-32) to ensure high strength and fatigue resistance. The shaft end is designed with a high-precision tapered hole (taper ratio 1:12), which is heat-fitted with the roller body to achieve efficient torque transmission.
