Uniform material distributing and screening system in ore grinding process

Abstract

A uniform material distributing and screening system in an ore grinding process comprises a buffer box, a uniform material distributing box and a double-layer linear vibrating screen, a first baffle is arranged in the buffer box so that first-section ground ore pulp and second-section ground ore pulp can be fully mixed, and a second baffle is arranged at the discharging end of the uniform material distributing box so that the ore pulp can be buffered again. And five screens with different sizes and different materials are distributed on each of the upper screen and the lower screen of the double-layer linear vibrating screen, so that the screening efficiency can be effectively improved. The uniform distributing and screening system can effectively control the ball milling circulation load, prevent ore from being over-ground, provide qualified materials for the later-section flotation separation procedure and facilitate improvement of beneficiation economic and technical indexes, so that the resource recycling rate is increased, and waste and loss of mineral resources are reduced.

Description

technical field [0001] The invention relates to a uniform distribution and screening system in the ore grinding process. Background technique [0002] Linear vibrating screen is a commonly used screening equipment. Its working principle is: using the principle of vibration motor excitation, the material makes a jumping linear motion on the screen surface, and the material enters the inlet of the screening machine evenly from the feeder, and passes through The multi-layer screen produces several specifications of oversize and undersize, which are discharged from their respective outlets. However, when the ore and sediment are separated unevenly, the effective screening area of ​​the linear vibrating screen becomes smaller, the screening efficiency decreases, and the cycle load of the ball mill becomes larger, resulting in greater fluctuations in the process, which is not conducive to grinding to produce qualified products, thus affecting the after-sales service. Stage flotat...
