Double-barrel ball mill for massive cement

Abstract

The invention discloses a block cement double-barrel ball mill, which comprises a base, an outer barrel and an inner barrel; the outer barrel is sleeved on the outside of the inner barrel, and the left side of the outer barrel is fixedly connected with a first rotating shaft. The left end is rotatably installed on the support frame; the right end of the inner barrel is fixedly connected with a second rotating shaft, and the second rotating shaft is rotatably installed on the support frame on the right side of the base; the outside of the inner barrel is evenly provided with a number of turning plates; the inner barrel An annular cavity is also provided on the inner wall of the base; a first shock-absorbing layer and a second shock-absorbing layer are arranged inside the base. The present invention adopts the double-barrel design with opposite directions, and the grinding efficiency is high, and a turning plate is arranged on the surface of the inner barrel to promote the turning of the cement blocks and steel balls, and further improve the grinding efficiency; there is also an annular cavity inside the inner barrel , in order to pass cold water into the inner space of the outer bucket to cool down the temperature, and prevent the steel balls from being severely worn when heated; a shock-absorbing base is also provided to improve the stability of the device.

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
