How to produce 100 mesh stone powder? Raymond mill is used for small investment, vertical mill is used for large capacity, and crushing system, air duct system, dust collection system and packaging system should also be considered.
The production of 100 mesh stone powder by Raymond mill can be summarized into 4 processes, as follows:
1. Ore grinding
The raw materials with suitable particle size are fed into the main machine through the feeding mechanism (vibration/belt/screw feeder or air lock feeder, etc.); the high-speed rotating grinding roller is tightly rolled on the grinding ring under the action of centrifugal force, and the The shovel scoops up the material and sends it to the grinding area formed by the grinding roller and the grinding ring. The material is crushed into powder under the action of the grinding pressure; under the action of the fan, the milled material is blown up through the sorting machine, Those that meet the requirements of fineness pass through the sorting machine, and those that do not meet the requirements are stopped by the sorting machine and return to the grinding chamber to continue grinding.
2. Powder collection
(1). Closed-circuit system: The selected qualified materials are blown into the cyclone collector through the pipeline, and the material and gas are separated by the action of the cyclone. The collected materials are sent to the next process through the discharge valve, and the separated airflow passes through the action of the fan. Enter the main engine and participate in the next cycle; after the excess air flow in the system passes through the pulse dust collector, it is discharged into the atmosphere to ensure the stable operation of the system; the collection efficiency of the pulse dust collector reaches 99.99%, ensuring that the discharge meets environmental protection standards.
(2). Open circuit system: The selected qualified materials are blown into the pulse collector through the pipeline, and the material and gas are separated through the action of the filter bag. The collected materials are sent to the next process through the discharge valve, and the separated airflow is passed through the fan. , into the exhaust pipe, and discharged into the atmosphere; the collection efficiency of the pulse dust collector reaches 99.99%, ensuring that the discharge meets the environmental protection standards.
3. Powder collection and treatment
The unloading valve below the cyclone/pulse collector can be directly bagged and packaged by the packaging machine, or directly loaded into the truck for transportation by the bulk machine, and can also be sent to the finished product warehouse for storage through the conveying mechanism.
