Iron removing, impurity removing and purifying process and system of potash feldspar ore and sodium feldspar by using dry method

Abstract

The invention relates to an iron removing, impurity removing and purifying process and system of potash feldspar ore and sodium feldspar by using a dry method, and belongs to the field of magnetic separators. The system comprises a jaw crusher, a fine crusher, a powder selecting device, a rare-earth supermagnetic iron removal machine, an ultra-magnetic purification machine, a high-gramoldnt granular sorting machine and a ball mill. Water does not needed, so that water resources are saved, and the defect that the beneficial components of the ore in a wet treatment process are lost along with the water is avoided; grading is performed according to the particle size, and the grading effect is good; and various byproducts are easy to recycle, medium breaking and medium separating are performed, more crushing and less grinding are achieved, and energy is saved.

Description

technical field [0001] The invention relates to a technology and system for removing iron and impurities by dry method of potassium feldspar ore and albite, and belongs to the field of magnetic separators. Background technique [0002] Potassium feldspar and albite feldspar are used in the ceramic industry as ceramic body ingredients and ceramic glazes, accounting for 30%, and the rest are used in chemical industry, glass flux, enamel raw materials, abrasives, glass fibers, welding rods and other industries. With the development of the economy, the consumption of glass products and architectural ceramics is increasing, the demand for potassium feldspar is increasing, and the market prospect is broad. [0003] With the vigorous development of the ceramic industry, the massive consumption of potassium feldspar and albite resources has reduced the reserves of potassium feldspar and the cost of mining has increased, so the price rise of potassium feldspar and albite has become i...

AI Technical Summary

Problems solved by technology

[0004] At present, judging from the nature of potassium feldspar and albite enterprises in my country, the current production and processing operators of potassium feldspar and albite are mainly private enterprises, and most of them are wet processes, which are a great waste of water resources and even cause pollution to water bodies.

It is necessary to carry out wet powder drying, and the final market acceptance is dry powder, which will inevitably consume heat energy

cause unnecessary waste of resources
