Description

A grinding device

Technical Field

The utility model relates to the technical field of powder grinding, in particular to a powder grinding device.

Background technique

Grinding devices are widely used in the grinding and processing of mineral products and waste materials in the fields of metallurgy, building materials, chemicals, mining, etc. A large amount of dust will be generated in the process of grinding materials from blocks into powder. Since traditional grinding devices do not have special structures to deal with dust, a large amount of dust will be distributed in the air. The dust in the air will cause damage to the health of workers and needs to be improved.

China Patent Network CN218359788U provides an electric grinding device, which relates to the technical field of grinding equipment, including a grinding box, a feeding port is provided on the top of the grinding box, a powder receiving box is slidably inserted at the bottom of the grinding box, a receiving hopper is slidably installed inside the grinding box, a screen is installed at the bottom of the receiving hopper, a mounting box is installed in the middle of the screen, a crushing motor is installed inside the mounting box, a blade is installed at the driving end of the crushing motor, and a pre-crushing mechanism is also provided inside the grinding box, and the pre-crushing mechanism is arranged above the receiving hopper. In this utility model, the material can be pre-crushed into small pieces, which improves the continuity of the grinding work and the grinding treatment effect of the material, thereby improving the work efficiency, and the practicality is high. At the same time, the screening speed of the powder material is accelerated, and the grinding efficiency is improved. However, the grinding device does not have a special structure designed to handle dust, so a large amount of dust generated during the grinding process will be distributed in the air, and the dust in the air will cause damage to the health of the staff, which needs to be improved.

Chinese Patent Network CN217856414U provides a grinding device, including a crushing box, a machine box is arranged at the bottom of the crushing box, mobile frames are arranged on the four sides of the machine box, a working box is arranged on one side of the crushing box, crushing and rolling rollers are rotatably installed inside the crushing box, and the number of crushing and rolling rollers is two, and a first welding plate is arranged inside the crushing box. The utility model is provided with a crushing and rolling roller, a worm, a turbine and a cutting rotary cutter assembly. The two crushing and rolling rollers move relative to each other, so that the selenium-rich rice is initially crushed and squeezed, so that the selenium-rich rice can become smaller and broken, and then enter the bottom for secondary grinding. The first drive motor is started, so that the cutting rotary cutter assembly rotates inside the screening centrifugal cylinder to grind the selenium-rich rice into powder. At this time, the particles of the selenium-rich rice become finer and smaller, which can protect the cutting rotary cutter assembly, so that the cutting rotary cutter assembly can be quickly ground into powder, and the service life of the cutting rotary cutter assembly is extended. However, the grinding device is not designed with a special structure to handle dust. Therefore, a large amount of dust generated during the grinding process will be distributed in the air. The dust in the air will cause damage to the health of the staff, and improvement is needed.
