(1) Grinding Stage: Dry the wet slag first, and then feed it into the main grinding room for grinding. The fine powder after grinding is classified by the analyzer under the action of the air flow of the fan, and the qualified fine powder enters the collecting stage. (2) Collecting Stage: The fine powder with qualified fineness enters the pulse dust collector. It is separated and falls directly into the bottom of the ash hopper. Residual dusty gas enters the bag filter area. With the extension of filtering time, all the dust will fall into the ash bucket, collect and discharge centrally. (3) Conveying Stage: The slag powder is sent from screw conveyor to plate chain elevator, and then into finished material tank. After collecting, the finished product is stored in the finished product tank, and the clean gas is discharged. (4) Finished Product Stage: The slag powder obtained from the powder can be directly sent to the customer for on-site use without additional downstream processing procedures.
Powder Requirements
(1) Used for recovering metalsProduction Fineness: S95
Zinc-germanium slag and matte slag can be used to recover metals.
(2) Slag powder supply to cement plant or mixing stationProduction Fineness: S105
Steel slag, water slag, manganese slag, nickel-iron and coal slag can be used as admixtures for concrete mixing station after grinding.
The Main Uses:1) Direct mixing of slag and Portland cement in a certain proportion in cement production can improve the performance of cement and reduce production costs and energy consumption. The amount of water slag in slag and Portland cement is 20%-70% by weight.
2) In ready-mixed concrete and cement products, some cement can be substituted or super-substituted in medium amount. As cementitious materials, concrete and mortar can be directly mixed to improve their working performance.
