Mineral powder plays a filling role in asphalt mixture, which can reduce the void of asphalt concrete, reduce the amount of cement, improve the workability of concrete and reduce the heat of hydration.
(1) Grinding Stage
Suitable raw materials are fed into the main grinding room of the feeder for grinding. The fine powder after grinding rises under the action of the air flow of the fan and is sent to the analyzer for grading. The fine powder with qualified fineness enters the collecting stage through the outlet pipe.
(2) Collecting Stage
The dust gas enters the cyclone collector of the main engine. Under the action of centrifugal force, most of the fine powder of the finished product is separated, collected and transported to the conveying stage. At the same time, the exhaust gas passes through the pulse dust collector and becomes the clean gas to be discharged.
(3) Conveying Stage
The finished ore powder is transferred from screw conveyor to bucket elevator, and then into slender deep warehouse finished material tank. The dust gas in the tank is collected by the top dust collector, and the finished product is stored in the finished tank, and the clean gas is discharged.
(4) Finished Product Stage
The ore powder obtained after powder can be directly sent to the customer for on-site use without additional downstream processing procedures.
