Material feeding device for cement production line

Abstract

The invention discloses a material feeding device for a cement production line. The material feeding device comprises an oblique spiral feeding device, a drying device and an air heating device which are sequentially connected, wherein the oblique spiral feeding device comprises a horizontal feed inlet, an oblique upward spiral transmission section, a horizontal transfer section and an oblique feeding section which are sequentially connected; the drying device and the air heating device are respectively connected on the oblique upward spiral transmission section and the horizontal transfer section; the temperature of hot air blown out by the air heating device is maintained to be 45 degrees or below; the drying device is an electric heating device, and comprises a plurality of heating units which are arranged at the bottom of the oblique upward spiral transmission section, and a heater connected with the heating units; the air heating device comprises a circular ring-shaped spray ring which sleeves the upper part of the horizontal transfer section; a plurality of spray holes are formed in the inner wall of the circular ring-shaped spray ring; and the circular ring-shaped spray ring is connected with an air heater to acquire an air source. According to the material feeding device for the cement production line, the production efficiency is high, and cement uniformity and fineness quality are relatively high.

Description

technical field [0001] The invention relates to the technical field of cement production equipment, in particular to a material supply device for a cement production line. 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 for ce...

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
