[0026] The use of the utility model:

[0027] First of all, it should be made clear that the grinder involved in the present invention is mainly used for grinding materials. The present invention takes the grinding of elastic materials as an example to explain its method of use in detail. When the elastic material needs to be ground, the plastic particles to be ground are introduced into the feed bin 101 with the help of an automatic feeding device such as a vacuum feeding machine. At this time, the filter plate 212 will screen the material, and the plastic particles passing through the filter plate 212 will enter the grinding bin 102 and be ground by the rotating grinding roller. The ground powder will be discharged and collected through the storage bin of the grinder. When the operator looks through the observation window 40 0 It is observed that no plastic particles fall and the situation that there is no material in the automatic feeding device is ruled out. Then the door of the feed bin 101 can be closed, and the door of the grinding bin 102 can be closed at the same time. Then the vacuum cleaner 221 is started to work, and the vacuum cleaner 221 can adsorb and clean the materials and impurities blocked on the filter plate 212. The utility model can screen and remove impurities for the materials entering the Raymond mill through the filtering and impurity removal mechanism 200 set on the feed bin 101 of the Raymond mill, so as to avoid the materials from being mixed into the Raymond mill, causing the Raymond mill to be stuck or even blocked, thereby greatly improving the production efficiency.

[0028] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0029] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
