High Pressure Suspension Mill(Raymond Mill) is a new kind of mill, which is invented with great concentration and on the basis of many years of powder processing experiences. This invention starts an epoch of high efficiency and low cost in international mining industry. High Pressure Suspension Mill (Raymond Mill) can be used to grind non-inflammable and non-explosive materials with Moh’s hardness below 9.3 and moisture content below 6%, such as barite, limestone, pottery, scoria. Size of final products can be adjusted between 80-425 mesh (The fineness can reach 1000 mesh).High Pressure Suspension Mill can produce coarse powder between 30-80 mesh by adding special equipment. This Raymond Mill is widely used in the fields like mining, chemical industry, construction materials, metallurgy, etc.

Working principle Of The High Pressure Grinding Mill(raymond mill):
The whole system of High Pressure Suspension Mill(Raymond Mill) consists of main frame, decelerator, classifier, piping device, blower, jaw crusher, dustpan elevator, electromagnetic vibration feeder, and electric switch box , motor, etc.
1) Materials are firstly crushed by the jaw crusher; then the crushed materials is transferred to a hopper by the elevator and fed uniformly, quantitatively and continuously by the vibration feeder in the grinding chamber of the main frame for grinding. The grinding particles are brought up by the air current of the blower into the classifier for classification. The particles with the required fineness are brought up by the air current through the pipe into a cyclone collector for separation and collection and the finished particles are discharged from a pipe outlet.
2) Due to some moisture contained in the materials to be grinded, the heat resulting from grinding leads to the vaporized air which changes the airflow volume. Moreover, the outside air inhaled from the narrow gaps, of the piping connections can increase the volume of air current. Therefore, it is necessary to adjust to redundant air pipe between the blower and the main unit for keeping the balance of the air current. The redundant air is then guided into a cloth bag of a dust cleaner to collect the fine powder in the air. And the redundant air is discharged after purification.
3) the main unit runs with a central shaft is driven by a transmission device. The top of the shaft is connected with a quincunx stand, on which a grinding roller is installed to form a swing support, the grinding roller not only rotates around its own axis due to the friction, it also rotates around the ring.

High Pressure Grinding Mill(raymond mill) Technical Advantage:
1. Compared with the common Raymond grinding mill under the same power conditions, the capacity of the High Pressure Suspension Mill(Raymond Mill) can be increased by 10%; moreover, under the performance of high-pressure springs, the rollers grinding pressure on raw materials can be raised by 800-1200kgf.
2. The final product size of the High Pressure Grinding Mill(raymond mill) ranges from the maximum particle diameter of 0.613mm (30mesh) to the finest diameter of 0.033mm (425 mesh). A few materials can reach 0.013mm (1000 mesh) if you choose the High Pressure Grinding Mill(raymond mill).
3. All the mineral materials with Mohs hardness below 9.3 can be crushed by the High Pressure Grinding Mill(raymond mill)
4.The High Pressure Grinding Mill(raymond mill) dust-removing effect fully meets the national dust discharge standard.
5. The classifier is easy for adjustment.
