A kind of anti-blocking feeding port produced by grinding with ball mill

Abstract

The invention relates to an anti-blocking blanking hole for grinding production by utilizing a ball grinder. The anti-blocking blanking hole for grinding production by utilizing the ball grinder comprises a crusher, a conveyor belt, a blocking apron, an alkali liquor pipe, a thick pipe section, a ball grinder, a feed inlet, a thin pipe section and a return pipe. The crusher is arranged at the upper part of the feed inlet; the conveyor belt is arranged at one side of the feed inlet; a circle of the blocking apron is arranged at the periphery of the feed inlet; the bottom part of the feed inletis connected with the thin pipe section; the thin pipe section is located at the upper part of a pipe opening of the alkali liquor pipe; the inner diameter of the thin pipe section is at least 3cm smaller than the inner diameter of the thick pipe section; the alkali liquor pipe is arranged at a side wall of the thick pipe section; a lower-part pipe opening of the thick pipe section is connected with the ball grinder; the top end of the return pipe is connected with the bottom part of the blocking apron; the bottom end of the return pipe is connected with the thick pipe section and is located at the lower side of the alkali liquor pipe. According to the anti-blocking device designed by the invention, a pipeline is effectively prevented from being blocked, and the conveying efficiency of thepipeline is improved, so that the safety and the reliability of the pipeline are improved, and the anti-blocking blanking hole is suitable to be popularized and used.

Description

Technical field [0001] The invention relates to the field of industrial production equipment, in particular to a ball mill grinding and production of an anti-blocking discharge opening. Background technique [0002] At present, in the process of preparing alumina, large blocks of ore often block the thick pipe section of the ball mill. The stuck ore is usually covered with a thick layer of ore and ore slurry. It takes time, labor, and less manpower to open the feed opening. It takes more than ten minutes, or nearly an hour, which will cause the interruption of the supply of raw materials, seriously affect the quality of the product, and increase the cost. Control room control, on-site personnel can not control, they call to inform the situation is too late) caused a large amount of lye (mineral slurry) overflow, which seriously threatened the safety of workers and caused pollution to the surrounding workplaces. Summary of the invention [0003] The purpose of the present inventio...

Problems solved by technology

[0002] At present, in the process of preparing alumina in the pulp preparation process, large pieces of ore often block the thick pipe section of the ball mill. The stuck ore is usually covered with a thick layer of ore and pulp. It takes time and effort to open the feeding port manually. Then more than ten minutes, as many as nearly an hour, thereby causing the interruption of raw material supply, seriously affecting product quality, and increasing costs, while blocking the feeding port due to untimely discovery (simultaneously because the start and stop of the lye pump is the main Control room control, on-site personnel can not control, it is too late to call to inform the situation) causing a large amount of lye (slurry) spillage, which seriously threatens the safety of workers and pollutes the surrounding workplace
