Raw anode manufacturing includes production processes such as medium crushing and screening, grinding, batching, kneading, and molding and cooling. Petroleum coke (or residual material) 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 bucket elevator (the residual material is 1 Two-layer horizontal vibrating screen) screening process, the material with a particle size greater than 12mm is returned to the intermediate silo, and then fed by the electromagnetic vibrating feeder into the double-roller crusher (the remaining poles enter the impact crusher) for intermediate crushing and then re-screened.Materials with particle sizes of 12~6mm and 6~3mm can be directly entered into the corresponding batching bin, or can be returned to the double-roller crusher for re-crushing to less than 3mm, which facilitates flexible production adjustment. Materials of 6~3mm and 3~0mm are sent through the grinding mill to be ground into powder. How to grind raw anode powder? In order to ensure the compactness of the anode product, a certain proportion of powder (approximately 45%) needs to be added to fill the gaps between the granules when manufacturing the raw anode. The main sources of powder are coke dust collected by the dust collection system and some fine particles (6~0mm) separated from the petroleum coke. The incoming materials are crushed into powder by the grinding mill. A carbon company uses four 6R4427 Raymond mills for raw anode grinding.

The electromagnetic vibrating feeder is quantitatively fed into the swing mill. After the dust-containing gas coming out of the mill is sorted by the air separator, the coarse particles are separated and returned to the mill for re-grinding. The qualified fine powder is After being collected by the cyclone collector, it is sent to the powder batching bin, and the circulating air enters the grinding mill through the ventilator for recycling production. The excess wind generated during the grinding process is purified and discharged into the atmosphere. In addition to being used for ingredients, part of the powder is used as an adsorbent for asphalt flue gas during the kneading and molding processes. It is used for the adsorption treatment of asphalt flue gas. After adsorbing the asphalt flue gas, it directly enters the mixing and kneading section.

Raymond mill is often used for raw anode grinding. Its grinding method is that the main motor installed in the lower part of the machine body drives the grinding elements inside the mill to rotate along the roller ring on the inner wall of the simplified body. The material to be ground is distributed between the roller ring and the grinding element. Between them, they are crushed and crushed to achieve the purpose of grinding. This equipment has been widely used and recognized in the raw anode grinding process.
