Description

Technical Field

[0001] The present invention relates to the field of cement production equipment, in particular to an energy-saving cement clinker crushing device. Background Art

[0002] Cement clinker is a semi-finished product made from limestone, clay, and iron as raw materials, mixed in appropriate proportions. This raw material is burned until partially or completely melted and then cooled. In the cement production process, the cement clinker must be crushed before use to ensure the quality of the cement produced.

[0003] Cement clinker is typically crushed using various crushers, including impact crushers, roller crushers, jaw crushers, and cone crushers. However, a common problem with cement clinker crushing is the significant variation in particle size. Excessive particle size variation often results in uneven force distribution during the crushing process, significantly impacting crushing efficiency and particle size uniformity. This compromises quality, increases crusher operation time, wastes energy, and shortens the crusher's lifespan.

[0004] After searching existing data, we found that the current method to solve the problem of material particle size is often to add a screening structure before crushing, and screen out the materials that do not meet the standards through the screen. However, this screening method often causes the screen to clog after a period of time, which greatly reduces work efficiency. Summary of the Invention
