Embodiment 1

[0022] The specific implementation of this embodiment is as figure 1 As shown in the flow chart, the raw ore is powdered quartz, including crushing, sand making, screening and grading processes, of which:

[0023] The crushing process: the powdered quartz is crushed by a crusher, and the powdered quartz coarse material obtained by crushing is transported to the coarse material bin by a chain conveyor;

[0024] The sand-making process: the powdered quartz coarse particles in the coarse-grained bin are transported to the ball-milling sand-making system through a vibrating feeder, and the sand-making system performs the preparation of quartz sand;

[0025] The screening and grading process: the quartz sand is first transported to the magnetic separator by the bucket elevator, and enters the first-stage drum screen after iron removal is completed, and the coarse particles obtained by the screening are transported back to the sand making system by the return belt for secondary prod...

Embodiment 2

[0035] The specific implementation of this embodiment is as figure 1 As shown in the flow chart, the raw ore is yellow quartz, including crushing, sand making, screening and grading processes, of which:

[0036] The crushing process: the yellow quartz is crushed by a crusher, and the yellow quartz coarse material obtained by crushing is transported to the coarse material bin by a chain conveyor;

[0037] The sand-making process: the coarse yellow quartz particles in the coarse-grained bin are transported to the ball-milling sand-making system through a vibrating feeder, and the sand-making system prepares quartz sand;

[0038] The screening and grading process: the quartz sand is first transported to the magnetic separator by the bucket elevator, and enters the first-stage drum screen after iron removal is completed, and the coarse particles obtained by the screening are transported back to the sand making system by the return belt for secondary production. Sand, quartz sand ...

Abstract

The invention belongs to the field of quartz sand production, and particularly relates to a processing technique of quartz sand. The invention aims to provide the processing technique of high-quality quartz sand, which has the advantages of low energy consumption and good product grain shape and particle size distribution. In order to solve the problem, the processing technique adopts the technical scheme that the processing technique comprises the steps of crushing, making sand, sieving and classifying. According to the processing technique, the operating principle that the crushing, grinding and classifying techniques are matched is fully used, continuous sieving and classifying is realized through process design, a series of 6 to 400-mesh products of more than 6 specifications can be stably produced, the average energy consumption is controlled to be 90 to 110 kW.h / t, the recovery rate of finished products is greater than or equal to 85%, and the comprehensive utilization rate of resources reaches more than 98%. The high-quality quartz sand obtained by adopting the processing technique can satisfy the production requirements of artificial quartz.

Description

technical field [0001] The invention belongs to the field of quartz sand production, in particular to a quartz sand processing technology. Background technique [0002] There are several major problems in the processing technology of traditional quartz sand products: First, technical equipment usually uses carbon steel materials. Due to the poor wear resistance of carbon steel, a large amount of impurities will be worn during use and enter the material, reducing product quality. , It is easy to wear out the outer wall of the equipment, the alloy parts are worn out, and the service life is short. Second, the crushing equipment used by most manufacturers produces large and angular product particles with poor particle shape and particle size distribution. Third, the production energy consumption is high, the efficiency and automation are low, and the continuity of sand making and screening and grading is poor. At present, the existing quartz sand has high energy consumption p...
