Novel spherical graphite processing technology

Abstract

The invention discloses a novel spherical graphite processing technology. The novel spherical graphite processing technology comprises the following steps that processing material data of a discharge point of a production line are acquired, and compared with preset standard data; when the obtained processing material data reaches preset standard data, a turnover bin used for accumulating materials is arranged at the discharging point; and when the materials accumulated in the turnover bin reach the maximum feeding amount of the next equipment of the production line, the materials in the turnover bin are put into next production equipment for continuous production. A traditional spherical graphite flow line production process is improved, and the stockpiling turnover step is added, so that on the premise that the spheroidizing effect can be achieved, unnecessary capacity waste is reduced, the production efficiency is improved, and the damage of a mill to spherical graphite is reduced; the produced spherical graphite is low in specific surface area; and when the turnover bin is full of one ton of materials, a crusher at the rear half section stops running, so that the electric charge is saved, and the cost is reduced by more than 20%.

Description

technical field [0001] The invention belongs to the technical field of graphite processing, and in particular relates to a novel spherical graphite processing technology. Background technique [0002] Spherical graphite material has good electrical conductivity, high crystallinity, low cost, high theoretical lithium intercalation capacity, low and flat charge and discharge potential, etc. It is currently an important part of lithium-ion battery negative electrode materials and is used in the production of lithium-ion batteries at home and abroad.

Problems solved by technology

The current spheroidization production line usually adopts a sequentially connected multi-stage crushing production line as described in CN201610216626.5, but this production line has the problems of low production efficiency and waste of production capacity, such as inputting 1 ton of raw materials per hour, but only It will produce 4 tons of finished products, which seriously affects the production progress and wastes raw material resources and processing energy
