Product Profile

Ball Mill is made up of feeding part, discharging part, gyre part, transmission part, (decelerator, small transmission gear, generator, electrical control) and so on. The hollow axis adopts the cast steel and the lining can replace , the rotating big gear processes in the way of casting rolling gear. The barrel body is wearable well and bears wearable scale board. This machine runs steadily and works reliably.

Ball Mill Working Principle

1. This ball mill machine, a horizontal type and tubular running device, has two chamber. This machine is grid type. The material enters first warehouse spirally and evenly along the input material hollow axis by input material device.

2. In this chamber, there is a ladder scaleboard or ripple scaleboard, and different specification steel balls. When shell rotates and it produces centrifugal force. At this time, steel balls will be carried to certain height and falls down to make the material heavy impact and grinded.

3. After being grinded coarsely in the first chamber, material enters second chamber for regrinding with the steel ball and scaleboard. At the end, the powder is discharged by output material board and the final products are completed.

Engineer Live Guide Vertical Coal Mill for Sale

Le 5 juillet 2017, 12:12 dans Humeurs 0

Chaeng Vertical Roller Mill has simple process, compact structure, product fineness of 80μmR 3%, with steady and average product fineness.

Application : Cement Plant, Clinker Grinding Unit, Mining

Capacity : 5-70 t/h

Motor Power : 110-1400 kw

Fineness : 80 μmR 3%

Vertical Coal Mill, also known as coal mill, for superfine grinding of raw coal, soft coal specifically for cement, power plant, steel mill and other fields. Its special design structure and production process creates the higher production efficiency with lower energy consumption, less dust, lower noise than ball mill, which meets national standard of energy saving industry. Chaeng’s Vertical Coal Mill technology reaches the international advanced level, and its manufacturing quality reaches the leading domestic level, and is the preferred equipment for grinding raw coal and soft coal.

In general, coal pulverisers are designed to achieve the maximum rated capacity grinding a design coal with a grindability of 55 HGI and 8-12 per cent moisture and achieving a discharge fineness of 70 per cent passing a 200 mesh screen (74 micron) and 99.5 per cent passing a 50 mesh screen. Variation of the coal hardness and/or moisture content will effect, up or down, the discharge capacity or the discharge fineness.

Vertical Coal Mill Process Flow

1. Raw coal from the yard are conveyed through screen to belt conveyors. The raw coals after iron removal by electromagnetic separator are put into the warehouse for storage.

2. After grinding system has started, please turn on the rod valve in the bottom of raw coal storage, and start sealing measuring belt to coal mill, then raw coal will be dryed and ground in the vertical coal mill.

3. The mixture of hot air or waste gas of cement production line are sucked into Vertical Coal Mill, under blower’s function. After complete heat exchange with ground coal, the coal powder are brought to separator for separation. The unqualified coarse coal powder falls to the grinding table for regrinding. The qualified coal powder will be collected with the airflow into the anti-explosion impulsive dust collector, through the grid wheel are discharged into pulverized coal storage.

4. The debris of raw coal, such as coal gangue, metal block, etc. will be discharged through the wind ring, discharge hole.

Energy-efficient Cement Vertical Roller Mill Customer Designed

Le 4 juillet 2017, 08:48 dans Humeurs 0

Cement Vertical roller mill (VRM) is mainly used to grind cement clinker into fine powder during cement production, which can also be used to grind various materials such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite etc.

Application : Cement Plant, Clinker Grinding Unit, Thermal Power Plant

Capacity : 50-250 t/h

Motor Power : 1250-5300kw

Fineness : 3300-3800 cm²/g

cement mill is widely used in the grinding of cement raw meal, slag(GGBS plant), cement clinker, raw coal and other raw materials. It gathers grinding, drying and powder selecting as a whole, with high grinding efficiency and high drying capacity ( the maximum handling material moisture is up to 20% ). The vertical mill adopts dynamic powder selecting device, which comes with high powder-selecting efficiency and convenient adjustment of fineness.After crushed by crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.The grinding disc is driving by motor through reducer.

The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high effiency classsifer.

The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.

 Cement Vertical Roller Mill Feature:

1. Technique and technology is mature and stable

Great Wall Company's GRMK series Vertical cement mill in the production of cement specific surface area up to 3800 cm²/ g with stable and reliable quality, it already have been the ability completely to replace tube mill.

2. Reducing the power consumption of cement clinker preparation effectively

According to the display of pulverized coal measured data, it can be saving electricity above 30% use of vertical roller mill production per ton cement clinker than traditional ball mill, and the power saving effect is very remarkable.

3. Stable, high-efficiency and environmental protection

There is a low vibration and noise in overall system, and equipment with whole sealing, system working under negative pressure with no dust overflow, clean environment. Therefore, cement vertical roller mill meets the national environmental protection requirements. With working mechanism changing, cement vertical roller mill can be reduced friction and improved service life.
