Full-automatic quartz sand production line

Abstract

The invention discloses a full-automatic quartz sand production line. The full-automatic quartz sand production line comprises an assembling floor; the assembling floor is sequentially provided with a storage silo, a multifunctional airflow classifier I, a pulse dust catcher I, a multifunctional airflow classifier II, a pulse dust catcher II, a multifunctional airflow classifier III and a pulse dust catcher III; the assembling floor between the storage silo and the multifunctional airflow classifier I is provided with a pit; a ball mill is arranged in the pit; the pieces of equipment are connected to the same control box. The full-automatic quartz sand production line overcomes the defects in the prior art and is reasonable in design structure; the airflow magnitude is adjusted according to the crystal structure of quartz sand ore and different densities of components, and quartz sand with high concentration is separated; an air floatation principle pure physical method is utilized for design, so that the produced quartz sand has few impurities and is low in cost; in second-level airflow classification and third-level airflow classification, the granularity is completely adjustable and controllable by controlling vortex airflow generated by classifying impellers, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of quartz sand production lines, in particular to an automatic quartz sand production line. Background technique [0002] Quartz sand is a non-metallic mineral. It is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white, or colorless and translucent, and its hardness is 7. , quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries; quartz sand It is the main glass raw material. On the one hand, it has the largest content in glass raw materials. On the other hand, it plays a great role in the production of colorless glass. Therefore, the purity of the quartz sand (that is, no contaminating ...

AI Technical Summary

Problems solved by technology

[0003] The existing quartz sand production line is composed of main equipment such as jaw crusher, ball mill, classifier, magnetic separator, flotation machine, thickener and dryer, etc., and can be combined with a feeder, hoist, and conveyor to form a complete The beneficiation production line needs to be combined with chemicals, and then needs to be dried. The process is cumbersome and the purity of the produced quartz sand is relatively low.
