Supply of Raymond mill in Nanchang, Jiangxi, fineness adjustment is convenient and flexible, performance is stable and reliable

Zhengzhou Qunzhi Machinery Co., Ltd. specializes in the production of Raymond mill. This mill is suitable for mining, building materials, chemical industry, metallurgy and other industries. It can grind limestone, calcite, barite, dolomite, potash Feldspar, talc, gypsum, kaolin, bentonite, phosphate ore, manganese ore, glass, ceramics, activated carbon, carbon black, refractory materials, thermal insulation materials, chemical raw materials, etc. The Mohs hardness is not greater than grade 1 and the temperature is below Explosive materials are processed by grinding, and the particle size of the finished product can be adjusted here.
The working principle of Raymond mill
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. It is broken into powder under the action of the fan, and then the powdered material is blown up and passed through the analyzer under the action of the fan. The material that meets the fineness requirements passes through the analyzer, and the material that does not meet the requirements is returned to the grinding chamber to continue grinding and passes through the analyzer. The materials enter the cyclone separator for separation and collection. Industrial filter cloth is used to isolate the exhaust air and turn it into powder at one time. Scope of application: This machine is mainly used for limestone, barite, 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 industry, 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
The entire air flow system 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 rate. In addition, the connections between the pipes in the whole machine are not tight, causing outside air to be sucked in, which increases the circulating air flow volume, resulting in powder discharge. Occasionally, the machine may even explode. In this regard, the new European version of the ladder-type grinding mill has been equipped with explosion-proof measures on the upper part of the machine body, which can avoid accidental damage caused by the explosion of the Raymond mill to the greatest extent. At the same time, this situation can also By adjusting the residual air duct between the fan and the host machine, the balance of the air flow is achieved, and the excess gas is introduced into the collector, and the fine powder brought in by the residual air is collected, and finally discharged into the atmosphere from the upper section of the collector, or introduced into The exhaust gas is purified in the dust collector. However, the technical requirements for operators are relatively high, and they need to be discovered and adjusted in time.
