We supply Guizhou Anshun Raymond Mill with complete varieties, reasonable price, reliable performance and widespread users all over the country.

The working principle of Raymond mill is that the grinding roller rolls tightly on the grinding ring under the action of centrifugal force. The material is scooped up by the shovel and sent to the middle of the grinding roller and the grinding ring. The material is crushed under the action of the grinding force. The powdered material is then blown up under the action of the fan and passes through the analyzer. Materials that meet the fineness requirements pass through the analyzer. Materials that do not meet the requirements are returned to the grinding chamber to continue grinding. The materials that pass through the analyzer enter the cyclone for separation. separate collection. Industrial filter cloth is used to isolate the exhaust air and turn it into powder at one time. Scope of application of Raymond mill: This machine is mainly used for barite, calcite, potassium feldspar, limestone, talc, white stone, gypsum, etc. Highly fine powder processing of hundreds of materials such as non-flammable and explosive mineral products with Mohs hardness no greater than 1 and humidity below, chemical building materials products, etc. The product particle size can be adjusted arbitrarily within the range of the mesh. This series of products is divided into three series, including high-pressure micro-powder mill, forced-pressure suspension roller mill and ordinary Raymond mill, and more than ten models according to different materials, different fineness, different output and other requirements.
Raymond Mill
Accessories The complete structure of Raymond mill is composed of host analyzer, powder separator, pipeline device, blower, finished product cyclone separator, jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control motor, etc. composition. The main machine of Raymond mill is composed of frame air inlet volute, blade, grinding roller, grinding ring cover and motor.
The whole working process of Raymond mill for grinding materials. After the large pieces of materials are crushed to the required particle size by the jaw crusher, the materials are sent to the storage hopper by the elevator, and then passed through the vibrating feeder to uniformly and quantitatively continuously It is sent into the main milling chamber for grinding, and the ground powder is taken away by the air flow of the fan. After being classified by the analyzer, the powder that meets the fineness will enter the large cyclone collector with the air flow through the pipe, where it will be separated and collected, and then discharged through the powder tube to become the finished powder. The airflow is then sucked into the blower through the return duct at the upper end of the large cyclone collector. The entire air flow system of this machine is a closed loop and circulates under positive and negative pressure conditions.
Because the materials to be ground have a certain moisture content in the grinding chamber, the heat generated during grinding causes the gas in the grinding chamber to evaporate and change the air flow. In addition, the connections between the pipes of the whole machine are not tight, causing outside air to be sucked in, which increases the circulating air flow. , causing the mill to produce less powder or even explode. In this regard, the new European version of the ladder mill has been equipped with explosion-proof measures on the upper part of the machine body, which can minimize the accidental damage caused by the explosion of the Raymond mill. , at the same time, in this case, the air flow balance can also be achieved by adjusting the residual air duct between the fan and the host machine, and the excess gas is introduced into the small cyclone collector to collect the fine powder brought in by the residual air, and finally the The upper exhaust pipe of the small cyclone collector is discharged into the atmosphere, or introduced into a dust collector to purify the exhaust gas. However, the technical requirements for the operator are relatively high, and they need to be discovered and adjusted in time.
