Method for efficiently preparing feldspar glazes for ceramics

Abstract

The invention discloses a method for efficiently preparing feldspar glazes for ceramics. The method comprises the following specific steps: after raw feldspar ores are crushed, grinding the raw feldspar ores by a high-alumina ball grinding mill, classifying the raw feldspar ores in a spiral manner by a spiral classifier, and screening the raw feldspar ores by a high-frequency classifying screen, so that the sufficient dissociation of feldspar mines and the controlling the granularity can be ensured, the feeding granularity of the fed feldspar mines can be ensured, and conditions for the following magnetic separation and the classifying processes of a cyclone are created; separating and effectively removing magnetic impurities of the raw feldspar ores by the magnetic separation with various intensity in a classifying and multi-section manner of the granularity, increasing the kinds of products, and increasing the recovery of resources. Through the use of the technologies, such as the classification of the cyclone, the permanent magnet iron removal of a drum magnetic separator, the iron removal of a vertical ring pulsating high-gradient strong magnetic separator and the like, the adaptability and the reliability are greatly improved, the quality of the concentrates is effectively ensured and stabilized, the risk due to fluctuation of the impurity content is reduced, the separating efficiency and the comprehensive utilization of resources are improved, and the efficiently comprehensive utilization of the feldspar resources is realized.

Description

technical field [0001] The invention relates to a magnetic separation method for feldspar glaze, in particular to a method for efficiently preparing feldspar glaze for ceramics. Background technique [0002] Feldspar is the basic raw material for the production of building materials and ceramics industry. With the continuous development of the ceramic industry, high-quality feldspar resources are becoming less and less, while the market demand is increasing, which has caused the shortage of raw materials in the ceramic industry. [0003] Thanks to the rapid development of the ceramic industry, the feldspar processing industry has developed very rapidly in recent years, but the processing technology of feldspar has been in a relatively closed and backward state. The reasons are as follows: 1) Horizontal competition determines the confidentiality of technology, which limits the industry. Technological innovation and progress; 2) The feldspar processing industry is mostly deve...

[0003] Thanks to the rapid development of the ceramic industry, the feldspar processing industry has developed very rapidly in recent years, but the processing technology of feldspar has been in a relatively closed and backward state. The reasons are as follows: 1) Horizontal competition determines the confidentiality of technology, which limits the industry. Technological innovation and progress; 2) The feldspar processing industry is mostly developed by small and medium-sized enterprises, lacking the support of scientific research and technology, and developing slowly in production technology. 3) The feldspar processing industry is affected by regions and markets, and the overall development of the industry is restricted by regions. The industry branches are small and technically Difficulty in attracting more investment from social resources
