The manufacturing process of graphite block material

The manufacturing of graphite block material includes production processes such as medium crushing and screening, grinding, batching, kneading and forming and cooling.

①Medium crushing and screening

This project is equipped with a medium crushing and screening system for calcined anthracite. The calcined anthracite is fed by an electromagnetic vibrating feeder, and sent to a double-layer horizontal vibrating screen and a single-layer horizontal vibrating screen via a belt conveyor and a bucket elevator. The materials are screened and processed. The particle size is greater than 10mm. Return to the intermediate bin, and then feed the material from the electromagnetic vibrating feeder into the double-roll crusher. Sieving again after medium crushing. 10~6mm, 6~3mm granularity materials can directly enter the corresponding batching bin, or return to the double-roll crusher to be finely crushed to below 3mm, which is convenient for flexible production adjustment.

There are 3 kinds of granular materials, 10~6mm, 6~3mm, 3~0mm, 6~3mm, 3~0mm. In addition to directly entering the batching bin, some of them are sent to the mill to pulverize into powder.

After being crushed to a particle size of less than 20mm in two stages in the processing section, the raw scraps are transported directly into the raw scrap silo by belt conveyors and bucket elevators for use.

②Grinding

In order to ensure the compactness of the graphite block material, a certain proportion of powder (about 45%) needs to be added to fill the gaps between the granules during the production of the graphite block material. The main source of the powder is the calcined anthracite dust, calcined petroleum coke and coke dust collected by the dust collection system and is pulverized into powder by the mill. Four pendulum mills (or Raymond mills) are used for grinding.
