High strength pulverizer, which is based on the long一term experience of researching pulverizer, and we adopted thousands of advice of our customers at home and abroad. After our concentration on research and our innovations, finally we produce this new type of the pulverizer. The crush of the material and the classification of the powder are put in one body but they operate separately. lts advantage is compact structure, adjustable discharging size, easy to repair, low energy consumption in unit product economical in investment etc.The crush process，classification process and the collection process will be done in a sealing system and the dusty air is dedusted and it is not polluted. This is the ideal equipment for grinding.
This machine is mainly used to pulverize the material under Moh's hardness 9 scale, 8% humidity in the trade of metallurgy, building material, mine and chemistry, such as duartz, feldspar, apatite, dolomite, barite, calcite, gypsum, tombarthite, iron ore, slag, water granulated slag, coal ash, betonies, kaolin, atlapulgite, and insulation material.
1. When the transmission is more stable: analysis of traditional machine part by drag type to the outside of the cavity cavity hanging, the drive rotates two cavity isolation, no swing center. At the same time, the host transmission device adopts closed gearbox and belt wheel, and the spindle and a quincunx structure transformation to make it stable. The operation is more stable and reliable.
2. The product fineness is higher: equipped with the ability to improve the accuracy of powder selection of high-density impeller, in the case of constant speed, to reduce the airflow resistance, the same power, grinding fineness of finished products higher
3. Lower failure rate, less loss of wear parts: High strength pulverizer model in the body is arranged at the upper part of the explosion-proof measures can explosion accident caused by machine avoid to the greatest extent. At the same time, the roller structure was updated, the grinding roller and the roller shaft can complement operation, improve the grinding and durability.
4. More energy saving and environmental protection: the bellows and duct are original to the center to the bottom horizontal tilt 30 degrees, to ensure the smooth air bellows, always without clogging, collected in ultrafine powder at the same time, to eliminate or reduce the pollution to the surrounding environment.
l .During operating the mill, there must be workers responsible for supervising. The workers should have professional technical knowledge.Before using the mill, the workers should be trained so that they can know the working principle well and be professional in operating mills.
2. In order to keep the mill working regularly, Operating duty on repair and maintenance of mill should be made to keep the machine running long time. At the same time, the inspecting tools, lubricating grease and spare parts should be prepared.
3.The machine should be overhauled after a period of running, and the spare parts such as rollers, grinding rings,nuts should be inspected and changed. Before starting or stopping grinding rollers，we should check whether connecting bolts and nuts are loosening and whether the lubricant oil is enough.
4.When grinding rollers is working over 500 hours or it should be changed, the antifriction bearing in the roller room should be cleaned and the damaged parts should be changed. The refueling tool can be used by P e dal一operated oil pump and grease gun.
