Problems solved by technology

In production practice, it generally undergoes rough selection, sweeping selection, regrinding and reselection once, regrinding and reselecting twice, regrinding and reselecting three times, etc., and the maximum reaches eleven times and then grinding and twelve times of selection. After these regrinding and reselecting After the selection process, the graphite flakes are greatly damaged, seriously affecting the particle size and yield of large flake graphite, which greatly restricts the application of graphite in important fields

Abstract

The invention relates to equipment and method for protecting large crystalline flake graphite in graphite beneficiation. According to the equipment and the method, the protection problem of the largecrystalline flake graphite in the graphite beneficiation is solved. The equipment comprises a bracket, a slot body, wear-resistant rubber rolls, a discharging hole, a material hopper, a bearing bush,a speed-adjustable motor I, a speed-adjustable motor II, motor support plates, a bracket tie bar, a tightening device, motor wheels, belts, a material hopper bracket, a wear-resistant rubber roll shaft and belt wheels, wherein two wear-resistant rubber rolls form a group and are horizontally arranged in parallel, the wear-resistant rubber roll shaft penetrates through the middles of the two wear-resistant rubber rolls, the interval between the two wear-resistant rubber rolls is 0-0.1mm, and multiple groups of the wear-resistant rubber rolls can be arranged and can be longitudinally placed in the same direction. The equipment is simple in structure, low in cost, easy and convenient to operate; and compared with a conventional grinding system, the equipment has the advantages that the energyis extremely saved, the protection effect of the crystalline flakes is good, each particle size quality is remarkably improved, the use technique is convenient to popularize, and the equipment is suitable for being used by graphite concentrating mills.

Description

technical field [0001] The invention belongs to the technical field of graphite beneficiation, and specifically relates to a large-scale graphite protection device and a method thereof in graphite beneficiation. Background technique [0002] Graphite ore can be divided into crystalline graphite ore and aphanitic graphite ore. Crystalline graphite ore can be divided into large scale graphite ore and small scale graphite ore. The larger the graphite scale, the wider the application range and the higher its value. Therefore, graphite mineral processing The factory regards improving the particle size and yield of flake graphite as its primary task and goal. [0003] The graphite ore beneficiation process mainly dissociates the useful mineral graphite and associated impurity gangue through continuous crushing of the ore, and continuously enriches the useful mineral graphite through flotation. [0004] Most of the beneficiation processes used in actual production are multi-stage ...
