Powder grinding equipment

Abstract

The invention relates to powder grinding equipment, which comprises a shell, a conveyer, a lifting device and a grinding device, wherein the conveyor comprises a conveyor belt and a driving roller. The powder grinding equipment also comprises a supporting component for supporting the conveyor belt, wherein the supporting component comprises a fixing plate and a movable plate which are arranged in parallel, and an electromagnet is arranged on the upper surface of the fixing plate; an iron block is arranged on the lower surface of the movable plate, and an elastic rest piece is also arranged between the fixing plate and the movable plate. The supporting component is arranged in the conveying device, and the electromagnet in the supporting component is intermittently electrified; when the electromagnet in the supporting component is electrified, the iron block is attracted down together with the movable plate, and the conveyor belt at the upper end also falls down; when the electromagnet in the supporting component is not electrified, magnetic force disappears, and the movable plate moves up under the action of the elastic reset piece, accordingly, the up and down movement allows the conveyor belt to move up and down, and the adhesion of a material on the conveyor belt and the surface of the conveyor belt can not be caused by the vibration, and the material cannot be coagulated, so that the following grinding efficiency of the powder is improved.

Description

technical field [0001] The invention relates to a grinding device, in particular to a powder grinding device. Background technique [0002] With the development of science and technology, the requirements for powders in dyestuffs, coatings, inks, chemicals, ceramics, electronics and other industries are getting higher and higher. The particle size distribution range of powders should be narrow and the grinding particle size should be uniform. The thickness of the powder directly affects the quality of the products it produces. At present, the grinders in the prior art only have a grinding function, without any other functions, such as a screening function. Many times when the operator grinds the powder, the room is full of flying powder, which is very easy to inhale In the mouth and nose of the operator, it has seriously affected the health of the operator. Moreover, the existing grinding machine has low production efficiency, poor load adaptability, easy occurrence of mat...

Problems solved by technology

At present, the grinders in the prior art only have a grinding function, without any other functions, such as a screening function. Many times when the operator grinds the powder, the room is full of flying powder, which is very easy to inhale. In the mouth and nose of the operator, it seriously affects the health of the operator

Moreover, the existing grinding machine has low production efficiency, poor load adaptability, easy occurrence of material clogging in the production process, and high unit energy consumption.
