A semi-final grinding system

Abstract

A semi-finished milling system is characterized by comprising a raw material warehouse (1), a first raw material conveying belt (201), a second raw material conveying belt (202), a third raw material conveying belt (203), a first iron remover (301), a second iron remover (302), a first lifter (4), a vertical mill (5), a semi-finished product conveyor belt (601), a semi-finished product conveying air chute (602), a ball mill (7), a second lifter (8), a powder concentrator (9), a cyclone dust collector (10), a first fan (11), a bag type dust collector (12), a second fan (13), a vertical mill finished product conveying air chute (1401), a ball mill finished product conveying air chute (1402), a third lifter (15) and a finished product storage warehouse (16). Through regulating the fineness and the feed quantity of coarse particle products entering the ball mill, the milling efficiency and the power consumption of the ball mill are controlled, and the high milling efficiency and low energy consumption characteristics of the novel vertical mill are exerted to an utmost extent. Finally, the milling efficiency of the whole milling system is increased, and the energy consumption of the whole milling system is reduced.

Description

technical field [0001] The invention belongs to the technical field of material grinding equipment, and specifically relates to a grinding system used for grinding various materials in industries such as metal ores, non-metallic ores, energy sources, new materials, etc., in particular to a grinding system for grinding cement in the cement industry Semi-final grinding system for clinker. Background technique [0002] At present, the cement industry widely uses a single ball mill, a ball mill and a roller press or a combination of a ball mill and a vertical mill for grinding cement clinker. As we all know, the low grinding efficiency and high energy consumption of the ball mill are its notable characteristics. However, in view of the current situation of the industry, ball mills will not be completely eliminated, and will be widely and long-term existing in the cement grinding industrial system at home and abroad. [0003] In order to improve the grinding efficiency in the g...
