Novel pulverizing mill for preparing aluminate cement

Abstract

The invention discloses a novel pulverizing mill for preparing aluminate cement, and relates to the technical field of pulverizing mills, in particular to a novel pulverizing mill for preparing the aluminate cement. The novel pulverizing mill comprises a top fixing plate and a limiting sleeve, and a driving motor is fixedly mounted below the top fixing plate. The bottom of an output shaft of the driving motor is fixedly connected with a driving bevel gear, and the left side of the bottom of the driving bevel gear is meshed with a driven bevel gear sleeve through a tooth groove. According to the novel pulverizing mill for preparing the aluminate cement, the limiting sleeve is fixedly installed above a pulverizing sleeve, a powder discharging hole is formed in the bottom of the pulverizing sleeve, the limiting sleeve movably sleeves a transmission column, a pulverizing hammer is installed at the bottom of the transmission column, during work, feeding is convenient through a feeding sleeve, then the pulverizing hammer is driven to move up and down in a reciprocating mode, the crushing of ore in an inner cavity of the pulverizing sleeve is completed, the pulverizing hammer is adopted for pulverizing, so that the service life of the pulverizing hammer is prolonged, the frequency of replacing the pulverizing hammer is reduced, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to a novel pulverizer for preparing aluminate cement. Background technique [0002] Grinding machines are widely used in chemical industry, mining, steel, thermal power, coal and other industries. The basic grinding equipment includes: Raymond mill, high-fineness pulverizer, high-pressure micro-powder mill, high-pressure suspension roller mill, and It also includes related supporting equipment of the pulverizer such as: feeder, bucket elevator, conveyor, transmission equipment, etc. The pulverizer is suitable for barite, calcite, potassium feldspar, talc, marble, limestone, dolomite Stone, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, thermal insulation materials and other non-flammable and explosive minerals with Mohs hardness not greater than 9.3 and humidity below 6% High-fine powder processing of more than 280 ki...

AI Technical Summary

Problems solved by technology

[0003] In the existing pulverizers, the grinding method is usually to use a spatula and a grinding roller to complete the grinding of stones. During the working process of the mill, the thickness of the spatula is relatively thin, while the ore is relatively hard. After a period of use, the shovel will be worn out, and it is necessary to stop the machine to replace a new shovel, which is not conducive to high-efficiency production. In addition, in the existing air selection feeding process, an external fan is usually required to cooperate with air selection to discharge the material. It will lead to a large power demand for the external fan and increase the production cost. Therefore, we propose a new type of grinding machine for aluminate cement preparation
