energy-saving raymond mill working principle 

First the materials are crushed by the jaw crusher,then the crushed materials are transferred to a hopper by the elevator ,fed uniformly.quantltatively and continously by the vibration feeder to the grinding chamber of the main frame for grinding.the grinded 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 collector for separation and collection,the finished particles are discharged from a pipe outlet,Because of 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.Therefor,it is necessary to adjust redundant air pipe between the blower and the main unit for keeping the balance of the air current.Then the redundant air is quided into a cloth bag of a dust cleaner to collect the fine power in the air,Finally, the redundant air is discharged after purfication.
barite grinding mill Structure  

barite grinding mill for stone consists of main frame,duct fan,analyzer,cyclone power collection device,bag duct collector and pipe connection.we will provide the elevator,bunker,electrical cabinet,feeder,crusherand so on. to meet clientsrequirements.
barite grinding mill Features and benefites  

 In the micro-power grinding room,the rollers hanged on the roller lifting frame,which is fixed with the main sheft and the scraper knife.the pressure spring press on the outer of the cantilever by tension rod,with the corss arm sheft as the supporting point.let roller tightly press on the inner surface of the ring.when the motor moved with equipment,the scraper knife on the scraper frame moved with the roller at the same time.as the roller moved on the inner sphere surface and moved itself.analyzer let the analyzer runner rotated by motor equipments,and the power fineness depend on the speed adjustment of the analyzer 
barite grinding mill Application
barite grinding mill  is suitable in grinding bartle,limestone,ceromic,coking coaland so on.it is mainly applied to the power processing of mineral products in the industries of mining,metallurgy,constrution materials and chemicl materials.ect.more than 280 kinds of high finesse power grinded,and the final product size can be adjusted as requied in the rang of 80-425meshes(even til 1000meshes).
Maintenance and Repair of  barite grinding mill 
1. During the application of our barite grinding mill  , some personnel shall be arranged to take responsibility of management from beginning to end. The operators must be qualified with the required technical knowledge of opreating grinding mills. Before the installation of this grinding mill, the persons related to the operation should receive technical training and fully understand the operating principle, performance and regulations of the  barite grinding mill 
2. In order to guarantee the barite grinding mill in a normal working state, a Safety Operation System for the Maintenance of the equipment must be established. Only in this way can the raymond mill be guaranteed to have a long-term and safe operation. Meanwhile, it is necessary to have the required repairing tools, lubricant and grease, spare parts and accessories during the operation.
3. After some period of running, the barite grinding mill should receive an examination and repairing. The components vulnerable to worn out, such as grinding roller, grinding ring, relieving tool etc. should be repaired or replaced. Before and after the operation, a careful examination should be carried out for the connecting screws, bolts and nuts on the grinding rollers so as to find whether they are loose or sufficiently lubricated
