The Production Technology of Dry Process

The structure of Raymond mill machine is composed by the body, analysis machine, pipe device, blower, and can be equipped with impact crusher, elevator, electro-magnetic vibrating feeder machine, electric motor, etc according to user needs. Material will be fed into the storage hopper through elevator, and then will continuous be fed into the body grinding indoor through vibration feeder. Material fine powder after grinding will be brought into analysis machine through blower cycle wind for sorting, while the coarse material fall back to have a re-grinding, and qualified fine powder is airflow into the finished product cyclone powder collector, via the powder tube discharge and become finished product. Due to the material be grinded in the grinding space has certain moisture, the moisture will be evaporated when grinding, and the various pipeline interface imprecision, outside gas be inhaled, cycle pressure high, the guarantee mill in the negative pressure condition work.


      Sand production line basic flow introduction: stone material evenly fed into crusher by vibrating feeder for coarse crushing, coarse material after first crushing will be fed into fine grinding mandibles crusher   by Conveyor belt for further fine grinding, fine grinding material wilol be sent to Sand making machine for further crushing to get sand, and then be delivered to the Vibrating screen for screening, finished product meet size requirements to be sent to the sand washer for cleaning, and then get finished products; materials have not reached finished size requirements return to sand making machine to re-process and form a closed multiple cycle. Product size can be combined and classified according to the needs of users. The dry process production technology can be equipped with finish powder separator and dust removal equipment.
