Super-fine whirl mill and its non-metallic ore wet method super-fine technology

Abstract

The grinding machine comprises motor drive portion, motor and motor base, abrasive disk, grinding cylinder and moving rollers, bearing seat, main shaft, main column, base , diaphragm pump and condenser which are connected together. The motor drive portion is connected with main shaft by means of bearing seat and fixedly connected on the motor base, the abrasive disk is embedded on the main shaft, feeding tube is connected with diaphragm pump, and cooling water inlet and outlet pipes are connected with condenser, the motor base is fixedly connected on the vertical column, the vertical column is fixedly connected on base, and the grinding cylinder is fixedly connected on the vertical column. It is high in grinding efficienc, short in technological process, narrow and uniform in grain size distribution, high in product quality, low in cost and long in life.

Description

【Technical field】 [0001] The invention relates to an ultra-fine swirl mill and its non-metallic ore wet ultra-fine process, which belongs to the grinding technology and equipment of inorganic materials. 【Background technique】 [0002] The existing non-metallic ore wet-process ultra-fine equipment is mainly sand mill. The principle of sand mill is similar to that of agitator mill. The lining material is mostly stainless steel, which will pollute the product during the grinding process. For example, using a traditional sand mill to grind kaolin in Maoming, Guangdong, China, will turn the kaolin gray and greatly reduce product performance. When using a centrifugal pump or a screw pump for slurry feeding, not only the slurry flow rate is unstable, which affects the grinding effect, but also the pump is easily damaged by wear and tear, which not only has a short service life, but also pollutes the product. Since a dispersant must be added during grinding, and the dispersant is ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome and solve the low grinding efficiency and uneven product particle size of the existing ultrafine mill, and because the slurry temperature is too high, the lining material of the grinding cylinder cannot be polyurethane but stainless steel, which will pollute during the grinding process. Products, reduced product performance, easy wear of the pump, complex process, high cost and other shortcomings and problems, researched and invented a kind of high grinding efficiency, a combination of ultra-fine and grading on one piece of equipment, narrow and uniform particle size distribution of the product, using tubes The type condenser effectively cools the grinding slurry, so that the lining material of the grinding cylinder can be made of wear-resistant polyurethane, which reduces the pollution of the material, improves the performance of the product, prevents the pump from wearing out, prolongs the service life, shortens the process, improves the product quality, and reduces the cost.
