Features of High-pressure Raymond Mill:
Raymond grinding mill improved the star rack, bearing room, center, in areas based on the orignal grinding mill ,has a powerful strength crushes impact for hardness materials by reasonable design and adding a powerful high-pressure spring device,thus can grind materials fully and increase output.
Detailed Description of High-pressure Raymond Mill:
This High-pressure Raymond Mill is used to grind materials in the fields of metallurgy,buliding materials,chemical and mining industry. It used to grind the materials which are non-inflammable and non-explosive with the hardness below 7-8 Mohs and moisture level less than 6%,such as feldspar, clay, bentonite, calcite, talc, barites, fluorite, marble and limestone, dolomite, lime, activated carbon, kaolin, phosphate rock, glass, manganese, refractory materials, insulation materials, causticization, mullite and medical stone, blood attapulgite, iron ore, copper ore, silicon ore, ferric oxide magnesium, Barium salt etc.
Main Structure of High-pressure Raymond Mill:
Raymond Mill mainly consists of mainframe,analizer,blower,finished product cyclone separator, micro mist cyclone separator and air duct.. The mainframe is composed by frame,spiral into wind,shovel knife,grinding roll,grinding ring,cover shells and motor.
Working Principle of High-pressure Raymond mill:
Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separating by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugalblower through wind recycling pipe at the upper part of cyclone powder collector.
The grinded material in the grinding room may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated and changes the air current, and since the pipeline joints are not airtight, the external air is sucked in and the circulation air increases. Thus the balance of the air current can be achieved through adjusting air pipe which is between the air blower and the main engine. The superfluous air current will be led into the bag dust catcher; the fine powder that is along with the air current will be collected. And the superfluous air current will be discharged after being purified.
