Cement production line fine powder grinding equipment

Abstract

The invention discloses cement production line fine powder grinding equipment which comprises an inclined spiral feed device, a drying device, a hot air device, a pulverizer, a powder screening machine and a fine powder collector which are sequentially connected, wherein the pulverizer comprises a discharge pipe, a primary fan, a grader, a swing roller, an abrasive disk, a speed reducer and a motor which are sequentially connected from top to bottom; the inclined spiral feed device comprises a horizontal feed inlet, an obliquely upward spiral transmission section, a horizontal transmission section and an inclined feed section which are sequentially connected; the obliquely upward spiral transmission section is connected with the drying device, and the horizontal transmission section is connected with the hot air device; furthermore, the temperature of hot air blown out of the hot air device is kept below 45 DEG C; in addition, the pulverizer is connected to the top position of the powder screening machine through the discharge pipe; a smashing device is further arranged at the bottom of the powder screening machine, and the powder screening machine is connected with the fine powder collector through a collection pipe which is arranged at the top of the powder screening machine. The cement production line fine powder grinding equipment has the advantages of high production efficiency, higher cement evenness and higher fineness quality.

Description

technical field [0001] The invention relates to the technical field of cement production equipment, in particular to fine powder grinding equipment for cement production lines. Background technique [0002] Cement is a kind of cementitious material for construction. The cementitious material is generally an anhydrous solid substance in a metastable state in the atmospheric environment. It can dissolve in the mixing solution, dissolve inconsistently and react in situ, release heat, and form small-sized , a hydrate with a large specific surface area and a gelling property. Cementitious materials generally require sufficient grinding to achieve maximum efficiency in production and use, so cement production requires suitable grinding equipment. [0003] At present, there are problems such as high energy consumption and low production efficiency in the field of ultrafine grinding. The Chinese application number is CN201610073492.6, and the name is an ultrafine grinding system f...

AI Technical Summary

Problems solved by technology

To a certain extent, the production efficiency of ultra-fine cement is improved, and the energy consumption of cement production is relatively reduced. However, when the above equipment is in use, the grinding disc is subjected to the effect of preheating, the long-term use temperature is high, and the high temperature and airtight The air will produce mist, which will cause high temperature and high humidity in the mill, which will affect the product quality of the obtained ultrafine powder
