How do I adjust the fineness of Raymond Mill?

Raymond mill is a popular non-metallic mineral grinding machine with a wide range of application scenarios. How to control the thickness of Raymond mill? This refers to how to adjust the fineness of the finished product of Raymond mill.

The thickness of the Raymond mill directly affects the quality of the product. If it is too coarse or too fine, it will be detrimental to the downstream application of the finished product and affect product market competition. Therefore, when using Raymond mill for powder processing, its classification technology is very critical. The fineness of the finished product must be strictly controlled to meet customer needs. So, what controls the thickness of Raymond mill? This is mainly related to the impeller speed of the classifier and the air volume of the blower. Normally, if we want to produce products of a certain specification, such as 325 mesh, we need to adjust the speed of the classifier and the air volume of the blower to the appropriate state to ensure that the finished product just reaches this fineness. The parameter values adjusted here are mainly the classifier. and blower power.

When the finished product is lower than 325 mesh, we can appropriately increase the speed of the classifier, that is, increase its power, or we can reduce the air volume of the blower, that is, lower the power of the blower. If the finished product exceeds 325 mesh, it means it is too fine. Then use the opposite adjustment method, reduce the speed of the classifier or increase the air volume of the blower. This is the answer to how the thickness of Raymond mill is controlled.

Of course, there is another situation, that is, even if the speed has been adjusted to the highest level, the fineness of the finished product still does not meet the requirements. In this case, it is necessary to consider whether the grader does not match. The finer the powder is ground, the more and denser the blades of the classifier must be. Otherwise, the fine powder that meets the standard will not be selected anyway. It can be seen that in the matching of Raymond mill, it is very important to choose the appropriate grader.
