After many years of practice and improvement, Raymond Grinding Mill structure is getting perfect day by day. Due to its low consumption, low investment, environment friendliness, little floor space and much more efficiency than the traditional mill, it is widely used in the fields of metallurgy, building materials, chemical industry and mining for powder processing. And do you know the Application of Raymond Grinder Mill in Industrialization?
Due to Raymond mill roller mill, although the roll diameter increases slightly, but not grinding force increases.Later, Raymond branch and combustion engineering companies in the United States on the basis of developing a new generation of Raymond mill, referred to as VR grinding.The Raymond Grinder and was in many ways the structure is similar.It is worth noting that it is different from was tapered roller and plane grinding mill, and the use of cylindrical roller and belt with a 15 degree Angle of tilt on the surface of the grinding mill. Roller during inspection and maintenance has to dig out the similar grinding roll, and equipped with protection device, in order to prevent the metal contact between the roller and a millstone.In the Raymond Grinder roller can be raised in advance before start, so that we can reduce the starting torque of the motor.Raymond mill in the United States in the industrial application, usually used for the preparation of pulverized coal, the fineness of product change between 250-325 mesh, can undertake product fineness in the process of operation and production control operation.
Because of Raymond Grinding mill coal slow roll grinding force (centrifugal force) is limited by a roller roller diameter and rotational speed, the grinding at the time is only applicable to soft, low ash and coal quality material with good sex of grinding, and Germany"s coal is hard, ash content and high, need higher grinding force and the structure of Raymond coal mill is difficult to meet the requirements of grinding, hence Raymond coal mill not gained popularity in Germany. At a time when Raymond Grinding mill is suitable for the coal grinding requirements, hence Raymond coal mill in the United States had been widely promotion and application.
