Double-barrel ball mill for massive cement

Abstract

The invention discloses a double-barrel ball mill for massive cement. The double-barrel ball mill for the massive cement comprises a base, an outer barrel and an inner barrel; the outer barrel is arranged on the inner side of the inner barrel in a sleeving manner, a first rotating shaft is fixedly connected to the left side of the outer barrel, and the left end of the first rotating shaft is rotationally installed on a supporting frame; a second rotating shaft is fixedly connected to the right end of the inner barrel, and is rotationally installed on the portion, on the right side of the base, of the supporting frame; a plurality of material overturning plates are evenly arranged outside the inner barrel; an annular cavity is further formed in the inner wall of the inner barrel; and a first shock absorbing layer and a second shock absorbing layer are arranged in the base. The design of the double barrels opposite in rotating direction is adopted for the double-barrel ball mill for the massive cement, the powder grinding efficiency is high, the material overturning plates are arranged on the surface of the inner barrel and promote overturning of cement blocks and steel balls, and the powder grinding efficiency is further improved; the annular cavity is further formed in the inner barrel so that cold water can be conveniently introduced to lower the temperature of the inner space of the outer barrel, and it is prevented that abrasion is serious when the steel balls are heated; and the shocking absorbing base is further arranged, and the stability of the device is improved.

Description

technical field [0001] The invention relates to cement processing equipment, in particular to a block cement double-barrel ball mill. Background technique [0002] In the cement production process, the blocky cement clinker needs to be ground to a suitable particle size to form a certain particle gradation, so as to increase its hydration area, accelerate the hydration rate, and meet the cement paste coagulation and hardening requirements. Blocky cement clinker is generally ground with a cement ball mill. Cement ball mill is the core equipment of cement plant, the final process of cement manufacturing, and the process that consumes the most power. [0003] Existing cement ball mills generally adopt a single-barrel structure. Put the block cement and steel balls into the ball mill, and beat and crush the block cement through the turning of the steel balls. Since the steel balls are only turned over by the ball mill, when the cement inside the ball mill When there are many b...

Problems solved by technology

[0003] Existing cement ball mills generally adopt a single-barrel structure. Put the block cement and steel balls into the ball mill, and beat and crush the block cement through the turning of the steel balls. Since the steel balls are only turned over by the ball mill, when the cement inside the ball mill When there are many blocks, the rolling range of the steel balls is small, the impact on the cement blocks is not good, and the grinding efficiency is reduced; when the existing cement ball mill is working, a large amount of heat will be generated due to the repeated contact between the steel balls and the cement, which will cause the steel balls to be heated and worn seriously, increasing The economic cost of the ball mill
