Description

Grinding device

Technical Field

The utility model belongs to the technical field of grinding devices, and particularly relates to a grinding device.

Background

In the field of lithium ore grinding, a grinding device is a critical device, and after the grinding device grinds materials, the grinded material particles are usually required to be screened to obtain lithium ore powder particles meeting requirements.

The effect of screening mechanism is to separate the abrasive grain that produces in the grinding process according to different granularity to satisfy different technological requirements, if not set up screening mechanism in lithium ore grinder, will lead to following problem:

the granularity is not uniform: during the milling process, the lithium ore is crushed and milled into particles of different sizes, and without the screening mechanism, the milled particles cannot be separated, resulting in non-uniform particle size after milling. This will affect the subsequent process and reduce the quality and performance of the product.

The energy consumption is increased: grinding devices without a screening mechanism can cause the abrasive particles to mix together to form a mass of a large number of fine particles. These agglomerates are difficult to treat efficiently in subsequent processes, increasing energy consumption. In addition, the absence of the screening mechanism also causes particle accumulation inside the mill, increasing the resistance of the machine, further increasing the energy consumption.

The process is difficult to control: in subsequent processes involving lithium ores, classification of the abrasive particles is often required. Grinding devices without screening mechanisms cannot effectively separate and sort the ground particles, resulting in difficult control of subsequent processes. This will affect the quality stability and consistency of the product.

In summary, if the sieving mechanism is not provided in the lithium ore grinding device, the problems of uneven granularity, increased energy consumption, difficult process control and the like will be caused, so that the company hopes to develop a grinding device to solve the problems.
