Difference between Raymond mill and high-pressure suspension mill
Raymond Mill is classical and mature type with many years’ practice and unceasing improvement, whose frame is more and more perfect, and has the advantage of high efficiency, low energy consumption, small occupation area, less investment and little pollution. High-pressure suspension mill, as an updated version of Raymond mill, which is a new type of patented products developed in our Company combining many years’ physical truth and demands of industrial development, and creates a new era of international industrial milling with high efficiency and low energy consumption.
The whole structure of Vertical Roller Mill is composed of a host machine, analysis, plumbing, air blower, finished cyclone separator, jaw crusher, bucket elevator, electromagnetic vibration feeder, electric motors and other components. The host is composed of a frame, Raymond mill inlet volute, blade, grinding, grinding ring, a cover casing and a motor. A set of High-Pressure Suspension Mill consist of main frame, decelerator, powder separator, air blower, jaw crusher, bucket-elevator, vibrating feeder, hopper, bag filter, pipe-devices, motor and electric control panel, etc.
Working principle difference
Raymond mill: the bulk material by jaw crusher to desired size, by the elevator will be material to the hopper, the vibrating feeder evenly and quantitatively and continuously into the indoor host grinding, after the powder will meet the gas flow through the pipe into the large cyclone collector, were isolated and collected, then powder tube is finished powder. The airflow from large cyclone collector inhalation top return air duct blower. The air current of the whole system is a closed loop, and circulation in the flow of positive and negative pressure condition.
High pressure suspension mill: Firstly, raw material should be crushed by the jaw crusher to the size specified, then the crushed stuff is elevated into the hopper by the bucket-elevator, through vibrating feeder, evenly and continuously into the grinding chamber for powder-processing. After this, the ground stuff is carried by the air flow from the blower into the separator for screening. The fine powder is blown into the cyclone collector and is poured out through the output-powder valves as the final product and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.
Advantages difference of raymond mill
Compared with general Raymond mill, High-pressure suspension mill has following features: Unique design. The capacity increases 10-30% at the same power by designing a pressure device in the main milling cavity. High adaptation of material, which can mill material at 9.3 in Moh’s scale (Raymond mill at 7). Wide range of output granularity. The output size of High-pressure suspension mill is from 0.95mm to 0.013mm (30 meshes to 425 meshes), while the Raymond mill is 30 meshes to 325 meshes. Low electricity consumption. The electricity is adopted centralized control, which is easy to adjust.
