Professional Limestone Grinding Mill Powder Grinding Mchine For Sale
HD Small-size raymond mill is upgraded on the traditional raymond roller mill(4R3216;4R3220) by our engineer team which conbined domestic and overseas grinding case and suggestions .It’s a best choice for small scale powder-making project and star the mining business .This mill perfectly satisfies the production demands of the customers on 80-600mesh (180-23μm) powder.
The whole structure of Raymond mill is composed of a rolle mill,Driving system, Classifier, pipeline device, blower, finished cyclone collector , jaw crusher, bucket elevator, electromagnetic vibration feeder, electric motor .
the Raw materials by jaw crusher less than 20mm and lifted by the elevator to the storage hopper, then after vibrating feeder evenly and quantitatively and continuously into the Main machine grinding, grinded powder was blow by airflow away. Through the classifier separated, consistent with the powder fineness with air flow through the pipeline into the cyclone collector, were isolated and collected, and then by the powder in tube is discharged into the finished powder. Air flow from large cyclone collector is arranged at the upper end of the air return pipe suction blower. The air current of the whole system is a closed loop, and flow circulation in the positive and negative pressure condition
Material Available
For Nonflammable,non-explosive and brittle materials With Mohs hardness less than 7.moisture content is less than 8%,.
Such as :Limestone, calcite, fly ash, calcium carbide, kaolin, calcium carbonate, coal gangue, gypsum, grain slag, Mn ore, coal dust, bentonite, barite, marble, talc, refractory material
Cost-effeiency
It’s provides efficient control of Max product size(80-600mesh), with minimal power resulting in cost-effective production. The system offers maximum flexibility and control over mill variables, delivering controlled product quality at minimum operating costs.
Squirrel-cage Type Separator(Classifier) eliminate coarse powder spilling
It is adopts Squirrel-cage type powder separator, which is of relatively stable velocity field, high powder separating precision, high powder separating efficiency and accurate cutting diameter; in addition, Over-size steps sealing is connected with cage rotor, which can effectively eliminate the “coarse powder spilling” phenomenon.
This technology got patent certification in 2011.
a. The final product passing rate can be reach to 97% -99% commonly
b. The final product size can be at the range to 23micron -180micron (600-80mesh)
Capacity/Production increased 30% higher than traditional raymond mill
HD small-size grinding mill working as 3 or 4 rollers , the blower airflow going to the main unit ,air resistance decreased , more material to be grind per unit time
| Model | Roller size (mm) | Max.Feeding Size(mm) | Speed of Main Mill(r/min) | The Final Size(mesh) | Capacity(t/h) | Main Unit Power(KW) | Power of Air Blower(KW) | Total weight(ton) |
|---|---|---|---|---|---|---|---|---|
| GYM9720 | Φ320*200 | ＜20 | 145 | 80-600 | 1-5.5 | 45 | 37-45 | 12-14 |
| HD1280 | Φ370*240 | ＜20 | 125 | 80-500 | 2-7 | 55-75 | 55 | 14-16 |
Note: capacity in the table is deduced with the standard of limestone as raw material, sieving rate is assumed to be 97%
