Ceramic raw material classified grinding method

Abstract

The invention relates to a ceramic raw material classified grinding method, which comprises the steps of calculating the time T being equal to t*w required for grinding each raw material according tothe grinding time t required for the unit weight of each raw material and the planned total weight w of each raw material; classifying the raw materials with the same or similar required grinding timeT into the same group; mixing the raw materials belonging to the same group, and grinding; separately grinding the raw materials belonging to the different groups. The ceramic raw material classifiedgrinding method provided by the invention has the advantages that (1) the raw materials are ground in a classifying way, so that grinding equipment does not need to be distributed for each raw material independently, and the species and the number of the grinding equipment are reduced; (2) in most cases, the processing volume of the raw materials classified in the same group is more, so that large-scale equipment is favorably selected for grinding, and the advantages of high production efficiency and convenience in allocation cost of the large-scale equipment are fully utilized; (3) the grinding time required for various raw materials in the same group is the same or similar, so that the phenomenon of overgrinding of raw materials can be reduced and even avoided, and the quality of a ceramic product is improved.

Description

technical field [0001] The invention relates to a raw material processing technology for ceramic products such as wall and floor tiles. Background technique [0002] The raw material formula of ceramic products usually contains several kinds of raw materials that need to be ground, and the proportion of various raw materials in the formula often varies greatly. Raw materials with a small proportion require less processing, while raw materials with a large proportion require more processing. If a large ball mill is used to process a small amount of raw materials, it will cause overkill and reduce the utilization rate of the ball mill. On the contrary, if a small ball mill is used to process a large amount of raw materials, more ball mills are needed, which occupies a large area. However, if a ball mill of appropriate size is assigned to each raw material, the types and quantity of ball mills will be increased, and the advantages of cost sharing of large ball mills cannot be...

Problems solved by technology

If a large ball mill is used to process a small amount of raw materials, it will cause overkill and reduce the utilization rate of the ball mill

Conversely, if a small ball mill is used to process a large amount of raw materials, more ball mills are needed, which occupies a large area.

However, if a ball mill of appropriate size is assigned to each raw material, the types and quantity of ball mills will increase, and the advantages of cost sharing of large ball mills cannot be fully utilized.

If all the raw materials are mixed together for grinding, it seems simple, but in the grinding process, most of the raw materials have reached the particle size requirement, and the overall grinding time has to be extended only because a few raw materials have not reached the particle size requirement, resulting in Over-grinding of raw materials reduces the quality of ceramic products
