A ball mill for refractory production

Abstract

The invention discloses a ball mill for refractory production, comprising a barrel and a driving mechanism, wherein the driving mechanism comprises a frame, a motor is fixedly connected to the top of the frame, and the left and right sides of the inner cavity of the barrel are fixedly connected There is a hollow plate, and the invention relates to the technical field of ball mills. The ball mill used for the production of refractory materials blows hot air into the barrel through a fan, a heater and an inflatable tube, which can accelerate the drying of the materials in the barrel, and at the same time, can blow out the qualified raw material powder after crushing, so that it is not It will accumulate in the barrel to generate a buffer force for the falling of steel balls and bulk materials, thereby maintaining high-efficiency pulverization, and the outlet pipe can blow the blown powder into the powder separation mechanism for separation, while the powder When the separation mechanism is blocked, the air flow can also be transferred into the return air pipe, and then discharged back into the barrel, so that the main part of the ball mill can continue to work without stopping, and it is not affected by cleaning the powder separation mechanism, and it is easy to use.

Description

technical field [0001] The invention relates to the technical field of ball mills, in particular to a ball mill used for the production of refractory materials. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. This type of grinding machine is filled with a certain number of steel balls in its cylinder as the grinding medium. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation, glass ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials, and are widely used in mineral processing, building materials and chemical industries. They can be divided into dry and wet grinding methods. [0003] Chinese patent CN211246782U discloses a ball mill, which includes a driving device, a drum, a lini...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a ball mill for the production of refractory materials, which solves the problem of buffering the falling steel balls and bulk raw materials when a certain thickness of powder is accumulated at the bottom of the existing ball mill. force, reduce the crushing effect, and after a long time of use, the door set on the side is subjected to too many collisions, the hinges and locks will become loose, and even the door will be deformed, which will affect the sealing of the door
