Raymond mill in common fault Raymond mill is one of the following most competitive cone crusher mining machinery products, a new generation of Raymond mill small dust, low noise, and the area is also small Raymond mill not only greatly improved in energy efficiency, environmental protection also do very comprehensive. But if you usually use properly, it will cause some unnecessary trouble. Let's analyze what common problems: 1, feeding uneven or excessive feed machines are often caused by blockage recommended electromagnetic vibrating feeder can avoid this failure. 2, poor exhaust pipes, circulating air heating temperatures of the main motor, fan current decreases. 3, dust removal device failure: bag filter is mainly used for circulating air flow increased air flow, air flow while removing dust particles, after the increase of the exhaust gas purifying air flow from the plane, when the bag filter dust can not be normal operation, a lot of dust is easy to form the accumulation of particulate material in the duct, resulting from anti-Raymond mill circulation duct blockage. 4, grinding material moisture or viscosity is too large, poor material flow, moisture content directly affects productivity and efficiency, but the material is too wet will lead to cutting difficult, 4R Mill, sticky wall, clogging pipes, cutting mouth is not smooth and so on. 5, abnormal fan, the fan is to provide the circulating air inside the Raymond mill, circulating air can carry material particles after grinding through the duct into the analysis machine for sorting materials. Voltage instability may cause abnormal blowers, blower stream instability abnormal result, the material can not be evenly into the classifier in accordance with the procedure, resulting in the fan duct blockage. As Raymond Lei factory Zhengzhou Machinery Co., Ltd. is a research, design, development, manufacturing, services in one, with strong technical force, complete processing equipment, good service and modern scientific management. Zhengzhou Lei Machinery Co., Ltd. are welcome to my company to discuss cooperation. What is Raymond? Raymond also known as Raymond mill, mill, the English name: Raymondmill. It is suitable for all kinds of ore preparation, coal preparation, such as raw material powder processing ore, gypsum ore, coal and other materials. Raymond, Raymond mill, Raymond efficient, high pressure rotary roller mill. 1906 CVGrueber created in the southern suburbs of Berlin, Curt Von Grueber machinery manufacturing [1] plant, he obtained the use of patents in the United States produce the first station Maxecon mill, and for BEWAG in Berlin's MOABIT coal power plant equipment as grinding, 88 Mill , grinding energy of up to 5T / H, a few years sold nearly 600 units, 85 milling machines, grinding areas are applied in different industries. BEWAG proposed construction year higher yield coal mill. After ECLoesche shares and director Curt Von Grueber machinery factory decided to buy raymond centrifugal US patent discloses a ring roller mill, produced the first generation of Raymond system. The structure was erected in the center of the machine with a belt holder with rotating spindle plum, plum rack hanging three or more rotation roller rotating shaft driven at a constant rotational speed roller swings out, and In the centrifugal force of driving under the pressure mounted on the cylinder wall of the grinding ring. When the material into the grinding area under plow-shaped guide roller blade material beneath the action is brought to the front area of ??the roller. Since Raymond coal mill roller mill grinding force (centrifugal force) is restricted grinding roll diameter and rotation speed of the mill at the time only available in soft, low ash content and grindability good coal quality materials, and Germany hard coal quality, ash content and high need for higher grinding force, Raymond coal mill grinding this structure is difficult to meet the requirements, so Raymond coal mill in Germany have not been universal. At that time, just for the United States Raymond coal mill grinding coal quality requirements, so Raymond coal mill was in the United States has been widely promoted and applied. 4R milling machine, milling machine, the machine is provided by Lei Lei Machinery Co., Ltd. Zhengzhou. Zhengzhou Lei Machinery Co., Ltd. (www.hnzljx.net) (www.hnzljx.net) located close Xingyang Ying Zheng road intersection 500 meters west.
