Description

TECHNICAL FIELD

[0001] The utility model relates to a crushing machine technical field, especially a different granularity limestone crushing equipment. BACKGROUND

[0002] Limestone, as a common mineral raw material, plays an important role in many industrial fields such as construction, chemical industry, metallurgy, etc. In order to meet the production needs of different industries, improve the crushing efficiency and reduce energy consumption, researchers are constantly exploring and improving the technology of limestone crushing equipment. Although traditional crushing equipment such as jaw crusher, cone crusher, etc. can meet the production needs to some extent, there are problems such as high energy consumption, low crushing efficiency, uneven product particle size, etc. Therefore, the emergence of new limestone crushing equipment has become an inevitable trend of industry development.

[0003] The new limestone crushing equipment adopts advanced crushing principle and structural design, which improves the crushing efficiency and reduces the energy consumption per unit output. For example, some equipment realizes the effect of "more crushing and less grinding" by optimizing the crushing cavity type and increasing the crushing ratio, which significantly improves the production efficiency. At the same time, in view of the problem of uneven particle size of crushed materials of traditional equipment, the new crushing equipment adopts special crushing cavity design and adjusting device, which can ensure that the particle size of the crushed products is more uniform.

However, the piston mechanism used in the device for screening limestone with different particle sizes and sizes is low in efficiency, easy to cause material jamming, and has few screening particle sizes and low automation degree.
