Roller Crusher Roller Number of Rotations and Method for Pre

Roller crusher is a simple structure, in line with the requirements of the material size of the high intelligence equipment, in the construction industry, and the industrial part of the most widely used in contemporary development, the most indispensable a new type of machine, in the All kinds of metal, non-metallic, chemical mineral raw materials and building materials processing process, the roller crusher in which play a huge role, how to achieve energy saving, efficient completion of the process of crushing and grinding, the Union will help you Solve this new problem. The number of revolutions of the roller crusher: the appropriate number of revolutions of the crusher is related to the surface characteristics of the roller, the hardness of the material and the particle size of the ore. Generally speaking, the greater the ore grain size, the harder the ore The lower the number of revolutions, the number of revolutions of the roller crusher should be lower than that of the roller crusher.

However, the production capacity of the crusher is proportional to the number of revolutions of the roller. To this end, the crusher with a higher number of revolutions has been chosen in recent years. However, the increase in the number of revolutions is limited, the speed is too fast, the friction If the number of revolutions exceeds a certain limit, the friction is not enough to make the ore into the crushing chamber, and the formation of hysteresis, not only the power consumption increased dramatically, and the production capacity decreased significantly, while the roller wear serious, so The number of revolutions of the crusher should have a suitable value.

Roller crusher wear pattern: roller wear is caused by the surface of the roller by the friction of the raw materials and the surface of the gradual loss of the process, in the roller surface under the action of high stress, will form a local mechanical wear , This wear is uneven throughout the surface, generally formed from the roll back on both sides of the middle of the gradual deepening of the groove, the groove is mainly from the two leather surface out of the raw materials in the hard abrasive Of the wear, mainly belong to the grain wear. Roller quality no matter how good, will wear off. As long as the use of a long time, or use the wrong way, it will cause some wear and tear.If you have any question ,please e-mail me :sales13@hsmmachinery.com
