cement grinding mill for sale and stone grinding mill

1. Brief introduction of stone grinding mill and Cement Grinding Mill

Raymond mill produced by Xingbang Heavy Machinery is mainly used to grind non-inflammable and non-explosive materials with Moh’s hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass, etc . Raymond mill can be used in mining, chemical industry, construction materials, metallurgy, etc. The final products can be adjusted freely from 100 mesh to 425 mesh.

2. Working Process of stone grinding mill and Cement Grinding Mill

Firstly, raw materials are crushed by jaw crusher to the size required, then elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between the ring and rollers to accomplish the grinding.After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.

3. Features of stone grinding mill and Cement Grinding Mill

1). The whole mill is of spatial structure , less premise and systemic strong. The whole system from roughing, transportation, powder collecting to packaging forms a independent production system. High Efficiency Raymond Mill, Raymond Grinding Mill Used in Mining,Chemical etc Industry

2). Even granularity, sieving rate 99%, which is unapproachable for other mills. High Efficiency Raymond Mill, Raymond Grinding Mill Used in Mining,Chemical etc Industry

3). The driving device applies inclosed gear box and belt pulley, so the transmission is calm and the operation is reliable.

4). All the main parts of Raymond Mill adopt high quality steel, the resistant parts use high-performance proof materials, so the whole system has high wear resistance and reliable performance. The blade frame of the main machine keeps in touch with the materials , it is consisted of the upper part and lower part, when the lower part is worn down , just take down the bolts to exchange it .

5). Centralized controlling of the electrical system, unmanned operation , easy maintenance.
6). Less dust pollution, low noise. High Efficiency Raymond Mill, Raymond Grinding Mill Used in Mining,Chemical etc Industry

7). Adopting electro-vibrating feeder , it can feed evenly and is easy to adjust, features miniature size, light in weight, power saving and easy maintenance. High Efficiency Raymond Mill, Raymond Grinding Mill Used in Mining,Chemical etc Industry

4. Specifications of stone grinding mill and Cement Grinding Mill

1). The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system. High Efficiency Raymond Mill, Raymond Grinding Mill Used in Mining,Chemical etc Industry

2). Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach.
3). Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4). Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant. High Efficiency Raymond Mill, Raymond Grinding Mill Used in Mining,Chemical etc Industry

5). The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

5. Maintenance of stone grinding mill and Cement Grinding Mill

1). In using the milling machine, special and fixed persons takes charge and the operator must possess special technique. Make sure to be trained before using if some one want to use the milling machine so as to make them understand function principle and operation regulations.

2). For working order, we should establish "the equipment maintenance and safe operation system" . Simultaneously there are indispensable examining and repairing tools and lube grease. High Efficiency Raymond Mill, Raymond Grinding Mill Used in Mining,Chemical etc Industry

3). We need examination and repairing if we use the machine some time and replace the wearing parts. Before the rubbing roller device is used, the concerned must examine the bolt and nut and make sure the lube is enough.

4). When the rubbing roller device is used uninterruptedly 500 hours or about , we need exchange new rubbing roller and clear the axletree. If the axletree is damaged then the old must be replaced by the new and the concerned can filling oil by manual work butter gun.
