Raymond Mill

Brief Introduction

Raymond mill machine, also named Raymond Grinder, is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceram and slag below scale 7 of Moth's hardness and 280 odd sorts of non-inflammable and non-explosive stuff in the traded of mining, building material, chemical engineering and metallurgy for power generation and processing. The product size is adjustable on required in the range of 100-425 meshes. Raymond Mill is a powerful grinding machine in the heavy industry field.

Working Principle

During the working process of the Raymond Mill, the big materials are crushed by Jaw Crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and carried evenly and continuously by vibrating feeder into the main frame for grinding. The fine grinded powder are carried by the airflow from the blower to the classifier to be classified. The particles which meet the fineness enter the cyclone collector through pipe and are separated and collected there. They are discharged at the discharging valve to become finished products.The airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
