Automatic centrifugal screening treatment system for limestone pulverizing

Abstract

The invention relates to an automatic centrifugal screening treatment system which comprises a base, a discharging barrel, supporting plates, bearing plates, a screening mechanism and a material collecting box, wherein the discharging barrel is mounted in the middle of the upper end face of the base, the discharging barrel is of a cylindrical structure with an opening in the upper end, and the supporting plates are mounted in the positions, located on the left side and the right side of the discharging barrel, of the upper end face of the base; a bearing plate is mounted between the upper endsof the supporting plates, the screening mechanism is mounted in the middle of the bearing plate, and a material collecting box is mounted on the left side of the bearing plate and is of a box-shapedstructure with an opening in the upper end. The system can solve the problems in the process of screening lime powder by using an existing horizontal roller lime powder screening machine that the limepowder screening efficiency is affected as the lime powder screened is low in efficiency to fall, impurities in the screening cylinder is cleaned and is filled repeatedly, and the impurity cleaning efficiency in the screening cylinder is reduced as the overturn process of the screening cylinder is long when the impurities in the screening cylinder are cleaned and the like.

Description

technical field [0001] The invention relates to the field of limestone pulverization, in particular to an automatic centrifugal screening treatment system for limestone pulverization. Background technique [0002] Limestone is widely distributed, and it is also called in some places: limestone, marble, chalk, aragonite, white marble, horse tooth stone, etc. The main ingredient is calcium carbonate (CaCO 3 ), the Mohs hardness is about 3, and the nature is relatively brittle. Lime has many uses. It can be directly processed into stone as building aggregate, and can also be calcined to produce quicklime, or processed into powder for industrial raw materials. Lime powder is a white powdery substance with calcium carbonate as the main component. It is a fine powder obtained by crushing and grinding massive limestone. Lime powder can be prepared into lime mortar or cement-lime mixed mortar for masonry or plastering projects. Due to the wide range of applications of lime powde...

AI Technical Summary

Problems solved by technology

[0004] 1. The impurity lime powder in the horizontal drum type lime powder screening machine can only fall downward from the lower side of the screening cylinder after screening, which makes the falling efficiency of the screened lime powder slower and reduces the impact on the The efficiency of lime powder for sieving;

[0005] 2. Existing horizontal drum type lime powder screening machines are usually filled with lime powder and screened. After the screening is completed, the impurities in the screening cylinder are cleaned. When the cleaning of impurities in the screening cylinder is completed After that, the sieving lime powder can be filled again. The process of clearing the sieving cylinder and refilling the lime powder affects the efficiency of sieving the lime powder;

[0006] 3. The existing horizontal drum type lime powder screening machine usually needs to turn over its internal screening cylinder to clean up the inside. However, the impurity screening cylinder in the horizontal drum type lime powder screening machine The turning process is longer, which reduces the efficiency of cleaning the screening drum
