Efficient ore crushing technology and crushing system thereof

Abstract

The invention provides an efficient ore crushing technology and a crushing system thereof and belongs to the technical field of ore crushing. The crushing system comprises a rough crushing device, anintermediate crushing device, a first fine crushing device, a second fine crushing device, a first vibrating screen and a second vibrating screen. A raw ore material is divided with a vibration feeding machine, the raw ore material with the particle size larger than 250mm enters the rough crushing device, the raw ore material with the particle size smaller than 250mm enters the intermediate crushing device, the raw ore material enters the intermediate crushing device after being roughly crushed with the rough crushing device, the raw ore material is sent into the first vibrating screen after being crushed with the intermediate crushing device, the raw ore material with the particle size smaller than 13mm is sent into a storage bin, the raw ore material with the particle size larger than 13mm is sent into the first fine crushing device and the second fine crushing device through a vibration division funnel and enters the second vibrating screen through a material collection hopper afterbeing finely crushed, the raw ore material with the particle size larger than 13mm is sent into the second fine crushing device, and the raw ore material with the particle size smaller than 13mm is sent into the storage bin. The efficient ore crushing technology provided by the invention is reasonable in design and is high in crushing efficiency, good in crushing effect and beneficial to after-treatment through classification crushing after screening of ore material particle sizes; and with reasonable type selection of various mechanical devices, the system is stable in running and convenientto maintain and can effectively increase the yield.

Description

technical field [0001] The invention relates to an ore crushing technology, in particular to an efficient ore crushing process and a crushing system thereof. Background technique [0002] With the improvement of people's living standards and the continuous development of science and technology, the demand for various chemical products is increasing day by day, which makes the mining volume of raw materials continue to increase. Manpower and material resources, in conjunction with a variety of mechanical equipment, and the use of reasonable and effective mining techniques can produce ore. The mined raw ore needs to be crushed before the next abrasive treatment can be performed. Crushing is a very important step in the ore mining process. The more uniform the crushed particles, the smaller the particle size, and the higher the abrasive treatment efficiency. The feed particle size is 20mm. [0003] The current ore crushing system and crushing process are as follows: firstly, ...

AI Technical Summary

Problems solved by technology

[0003] The current ore crushing system and crushing process is that the mined raw ore materials are firstly crushed through the coarse crushing device, and the coarsely crushed particles are put into the medium and fine crushing device for secondary crushing. 1. The crushing efficiency of the coarse crushing device is low. After primary crushing, the ore particles have different thicknesses, and some ores are not crushed in place. They directly enter the medium and fine crushing device to affect the crushing effect. The failure rate of the device is high, the crushing effect of the crushing system is poor, and the production efficiency is low.
