How to use the roller crusher

Not all of the raw materials can be broken with the roller, such as the hardness of shale or coal gangue and other raw materials, broken up more difficult, for the flat shape (sheet) of the material, the crushing effect of the roller Is not ideal, because the gap between the two rollers roller will make the sheet material "leak" down, so that the crushing effect is reduced. If you encounter the above raw materials, should be used to combat the type of crushing equipment, such as hammer crusher, cage crusher and impact crusher and so on.

The surface of the roller crusher is easily worn and is often worn out of the groove, so that the gap between the two rollers becomes larger, so that the crushing effect is reduced. Therefore, the fineness of the crushing of the roller crusher is a sine wave state change, when the roller is a new time (or just after grinding), the gap between the two rollers the smallest, broken fineness finest, After grinding the groove, the gap between the two rolls becomes larger and the particle size of the raw material becomes thicker. This process of change from fine to coarse is the peculiar phenomenon of crushing the raw material of the roller crusher. So, we have to do the work is to minimize the change from the coarse change in the value of the broken particle size as far as possible within the control of the production process within the scope, so as to ensure the quality of the product. To achieve this goal, the only way is to constantly roller surface grinding (make up), so that between the two rollers to maintain a smooth and a certain gap between the gap, so as to ensure the fineness of raw materials broken.

The biggest drawback of the roll crusher is that the crushing ratio is relatively small and the particle size of the product changes with the gap wear of the roller, and the material breaking effect of the flaky structure is poor. To understand these shortcomings of the roller crusher, it should avoid weakness and reasonable arrangements and the use of roller crusher in order to give full play to the roller crusher high yield, low power consumption and wide adaptability to water. Therefore, the use of the roller crusher is most concerned about the gradual crushing of this method, for example, the majority of shale raw material crushing treatment, at least through the "coarse - broken - broken" three processes, that hope only A roller crusher to solve the problem is more naive.You can send me e-mail to me :sales13@hsmmachinery.com
