Processing ability: 0.8–60 t/hBrief introduction: Raymond Mill has not been eliminated. Raymond is the traditional mill with the most stable performance on the current market

Application:

Raymond mill is suitable for process in various non-flammable mineral which is below seven Mos hardness, moisture below 6%, such as limestone,calcitecarbonate,dolomite, barite, talc, gypsum, diabase, quartz, bentonite, bauxite, iron ore, etc.Fineness is between 613microns and 44mirons(0.613mm-0.044mm)By analytical machine and draught fan interaction,which can meet different users requirements.
Raymond Mill is created in 1906, even though there are more than one hundred years of history,Raymond Mill has not been eliminated. Raymond is the traditional mill with the most stable performance on the current market, now Raymond Mill is still prevalent in pulverized coal industry in the United States.

Features:

1. Small footprint, strong systemic
Vertical structure, small footprint, systematic, from raw materials roughing to transport to the milling to packaging, forming an independent production system.
2. Good stability, high reliability
Mainframe gearing adopts sealed pulley and gear box, smooth transmission , reliable operation. Raymond Mill important parts are made of high quality castings and extrusions , sophisticated technology and rigorous process to ensure that the durability of the equipment.
3. Good product size , through screening rate is 99%
Electrical system adopts centralized control, milling workshop basic enable unmanned operation. Compared with other milling equipment, through screening rate is 99%.

Working principle:

1. The whole structure of Raymond Mill is mainly including the host, analysis machine, plumbing fixtures and the blower, according to user needs, it can be equipped with crusher, elevator, electromagnetic vibrating feeder, electric control motors etc.
2. After materials crushed to the desired particle size, enter into the storage hopper by the elevator, and then through vibrating feeder enter into grinding chamber of Raymond mill uniform continuously.
3. Due to the centrifugal force when rotating, the rollers swings outward, pressed on the grinding ring, shovel blade scoop up materials, then sent them between grinding roller and grinding ring, due to the grinding roller roller rolling to achieve crushing purpose.
4. After grinding material, the powder along with the circulating air which made by blower, is brought into the analysis machine for sorting, coarse material will regrind. Qualified powder along with the air enters into finished product cyclone powder collector, then discharge powder tube, that is finished product.
5. In the grinding chamber of Raymond mill, because there are certain moisture in the grinded material, when grinding, it will generate heat, moisture evaporates, and the pipe interface of the whole is not tight, the outside air is drawn into making the circulation pressure increased to ensure that the mill wok under negative pressure. The increased air flow enter into the dust through the duct, at last enter into the atmosphere after purification.
