Description

Technical Field

[0001] The utility model relates to the technical field of roller grinding and crushing equipment, in particular to a composite side material baffle device for a roller press. Background Art

[0002] With the development of domestic ore dressing technology, roller grinding and crushing equipment, especially high-pressure roller mills, are increasingly widely used in medium and fine crushing and pre-grinding. As a pre-grinding equipment, high-pressure roller mills can greatly improve the efficiency of ball mills and reduce the grinding cost. They are widely used in various industries such as cement, slag, iron ore, feldspar, and other metal and non-metal mines, as well as building materials. Almost all ore dressing plants equipped with ball mills use them.

[0003] Due to the large feed particle size and large output of roller grinding and crushing equipment, the side material baffle device located outside the end of the pressure roller of the roller grinding and crushing equipment wears very quickly. After the side material baffle device is worn out, it will cause material leakage, seriously affecting the crushing effect. At present, the side material baffle device is usually only a side baffle plate. The side of the side baffle plate facing the pressure roller is processed and surfacing with a wear-resistant layer. And because the surfacing wear-resistant layer is too thick, it is easy to crack, leading to a reduction in service life. Even if a thinner surfacing wear-resistant layer is set, it will be worn out and perforated in a short time. It is necessary to disassemble the side baffle plate and then carry out internal surfacing again. While the operation is complex, frequent replacement of the side baffle device also increases the equipment maintenance workload and reduces the equipment startup rate.

[0004] Therefore, it is an urgent problem to be solved at present to research and develop a new composite side material baffle device that can effectively improve the service life, delay the wear speed, and is convenient for replacement and maintenance. Content of the Utility Model

The strong magnet can generate a magnetic field at the wear-resistant plate. During the crushing process of the material, ferromagnetic particles can be adsorbed onto the wear-resistant plate. The ferromagnetic particles form a protective layer on the wear-resistant plate, which can effectively reduce the wear speed of the wear-resistant plate, improve the service life, and the wear-resistant plate is detachably connected to the side baffle plate, which is convenient for replacement and maintenance.
