Kaolin preparation and processing technology

Abstract

The invention relates to a kaolin preparation and processing technology which uses grinding and crushing equipment; the grinding and crushing equipment comprises a shell, a grinding device and a material collecting device; the top end of the shell is provided with a feeding port, and the bottom end of the shell is provided with a first discharging port and a second discharging port; the grinding device and the material collecting device are sequentially mounted in the shell from top to bottom. When the grinding and smashing equipment is used for preparing and processing kaolin, the process comprises the following specific processes: dispersing, desanding, deironing, smashing, grinding and calcining. To-be-ground ceramic clay is fed into the grinding device in a batch discharging mode, theburden of the grinding device during work is small, improvement of the overall grinding sufficiency is facilitated, the service life of the grinding device is prolonged, equipment does not need to bedisassembled after grinding, the ceramic clay which does not meet the standard in specification can be put into the grinding device again for secondary grinding, and the complex degree of work is reduced while the grinding quality is guaranteed.

Description

technical field [0001] The invention relates to the field of non-metallic mineral processing, in particular to a kaolin preparation and processing technology. Background technique [0002] Kaolin is a non-metallic mineral, a kind of clay and clay rock mainly composed of kaolinite clay minerals. Kaolin is widely used, mainly used in papermaking, ceramics and refractory materials, followed by coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount of plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soap, Pesticides, pharmaceuticals, textiles, petroleum, chemicals, building materials, national defense and other industrial sectors. [0003] In the process of processing kaolin into ceramic materials, it needs to be pulverized and ground, but there are still the following problems in the process of pulverizing and grinding: [0004] (1) In order to facilitate operation and save time, manufacturers often put a large amount ...

Problems solved by technology

[0004] (1) In order to facilitate operation and save time, manufacturers often put a large amount of materials into the grinding equipment at one time, resulting in high working intensity of the grinding equipment. During high-intensity operation, the material will wear the grinding equipment to a large extent, shortening the service life of the grinding equipment. In addition, due to the large amount of materials in the equipment, the grinding equipment cannot fully grind the materials everywhere, and it is easy to cause insufficient grinding;
