Shanghai Joyal Raymond Mill

The purpose of the raymond mill is to grind materials in the fields of building materials, mining, metallurgy and chemical industry.The materials must be non-flammable and non-explosive materials such as: limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone, rock phosphate, manganese ore, iron ore, glass, ceram, active carbon,carbon black,fireproof materials, heat preservation materials, chemical materials and so on(300 kinds of materials).The materials should have the hardness less than 7 in moh's scale and humidity less than 6 percent.The granularity of the end products can be adjusted from 30 to 325 meshes.Working principle of raymond mill: after the materials are put into the grinding room of the main equipment, the grinding roll swings outward and presses closely upon the grinding ring due to the centrifugal force in rotation of the main shaft.The shovel carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roll rolls.After being ground, the powder is selected by separator via the cycle wind of the blower and the rough powder will be back to the grinding room for regrinding.The proper powder is brought into the powder collector together with airflow.The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally.The increased airflow comes out after purification.Main specifications of raymond mill: model grinding roll grinding ring feeding size (mm) output (mm) capacity (t/h) motor power (kw) overall dimension (mm) numbers (pcs) diameter (mm) height (mm) outside diameter (mm) height (mm) 3r2115 3 210 150 726 150 0.613-0.044 0.28-1.8 28.2 4480× 3100× 3970 3r2615 3 260 150 865 150 0.613-0.044 0.35-2.8 35.7 5000× 4100× 4850 3r2715 3 270 150 884 150 0.613-0.044 0.40-3.4 42.7 5050× 4150× 4900 3r3015 3 300 150 965 150 0.613-0.044 0.45-3.7 55 5200× 4200× 4950 4r3016 4 300 160 990 160 0.613-0.044 0.6-4.5 55 5250× 5000× 5500 4r3216 4 320 160 1073 160 0.613-0.044 1.0-5.2 72.5 7700× 7200× 8800 shanghai joyal mining machinery co., ltd is a high-tech enterprise, which is specializing in the research, development, and manufacture of industrial stone crushing & screening equipments, grinding mills, mining equipments and so on.Our company has already formed a full set of modern production line, equipped with intelligent and standardized testing, controlling laboratories, and owned a professional team of r & d, production, sales and service.So far, we have established a whole production chain, of which main products cover stone crushing & screening equipments: jaw crusher, cone crusher, impact crusher, vertical impact crusher, hammer crusher, vibrating feeder, oscillating screen, sand washer, belt conveyor;and grinding machinery: raymond mill, high-pressure suspension mill, ultrafine and roller mill, ball mill and so on.They are widely used in the industry of mining, construction materials, chemicals, metallurgies, transportation, hydraulic engineering and so on.Our products are not only renowned in more than 20 provinces and cities in domestic markets, but also have being sold popularly in more than dozens of countries and areas all over the world like eastern europe, middle east, africa, south asia, southeast asia, oceania, and central and south america etc.Shanghai joyal mining machinery co., ltd.Add: no.3389, east huaxia road, pudong new area, shanghai, china tel: 763311 763366 fax: 763366 post code: 201201.
