Device used for ore screening and smashing and screening and smashing method based on device

Abstract

The invention provides a device used for ore screening and smashing. The device comprises ore tanks used for containing ore materials, a plurality of vibrating screens used for screening the ore materials, a crusher used for smashing the ore materials, a movable sliding chute used for playing the effects of balancing and distribution, and overturning plates used for receding the first-class vibrating screen and the third-class vibrating screen. The device used for ore screening and smashing has the beneficial effects that the process is simple and short, the space occupied by equipment is small, classification cost is low, energy can be saved obviously, the technology is advanced, and the device is quite effective.

Description

technical field [0001] The invention relates to ore sieving and ore crushing process technology, and aims to reduce energy consumption while simplifying the process and ensuring product quality by rearranging the process flow of the vibrating screen and pulverizer treatment system. Background technique [0002] Raw material ore crushing, screening and ore crushing process production mode: ore crushing and screening system materials are crushed by 5 crushers and screened by 10 vibrating screens, and processed into fine ore suitable for use in blast furnaces; materials pass through The 0-8mm powder produced by crushing and screening is screened by 10 vibrating sieves in the system, of which 5 vibrating sieves sieve the powder materials into the under-sieve powder tank and send them to the stockyard to participate in the homogenization and accumulation. The crushed material of the ore crushing system is crushed and screened, miscellaneous ore, hot ore (ore) is processed into cr...

AI Technical Summary

Problems solved by technology

[0006] 1. The ore crushing, screening and ore crushing processing system equipment consumes a lot of energy, and the motor power is: 5778.7Kw

[0007] 2. The existing ore crushing and screening, ore crushing treatment system has a long process flow and frequent material transfers, resulting in material accumulation and blockage in the material chute during system operation. The machine is shut down due to overload failure, and the production operation cannot be stabilized

[0008] 3. Ore crushing, screening, ore crushing treatment system process is too long, frequent blockage of chute accumulation, and more on-site blanking, cleaning affects ore crushing, screening, ore crushing system operating rate

[0010] 5. The processing capacity of the ore crushing system is low, the operation is low, the equipment is idle for a long time, and the dynamic maintenance cost of the system equipment is large

[0014] 1. Because the process of the system is too long and the transfers are frequent, the operator's inspection points are many and wide, which inevitably leads to negligence. The inspection is not in place. During the operation of the system, equipment failures, material accumulation in the chute, and blockage of the vibrating screen screen cannot be found in time, resulting in system pressing accidents. ;

[0015] 2. The ore crushing and processing system has low processing capacity and low operation, long idle time of equipment, and high dynamic maintenance cost of system equipment;

[0016] 3. Crusher, rod mill, and vibrating screen have a high failure rate and high maintenance costs, and production cannot be effectively controlled
