Grate Type Mining Ball Mill In Chemical Industry With Capacity 25-75t/h

Description:

The mining ball mill is composed of feeding department, the material department, rotary department,

transmission department (reducer, small transmission gears, motor, electric control device) and other

major parts. Hollow shaft with steel castings, lining systems, rotary big gear are all by roll teeth

processed, the cylinder has wear-resisting lining, and good abrasion resistance. This machine is

smoothly operated, reliable.

Application:

In the mining machine field the most important equipment is the mining ball mill, the machine can be

used in gold ore, copper ore, iron ore, zinc&lead ore, limestone, gypsum, sand, slag’s grinding.

Materials only after being grinded to the required fineness and then fully mixed interaction, which makes

the products to some strength, grinding is an important procedure in the production, it needs large

power consumption in grinding process, mining ball mill is generally the largest capacity equipment in

factory.

The ball mill host includes cylinder and liners made of wear-resisting material inside cylinder, the

bearing to support the cylinder and sustain the rotating, also driving parts, such as, motor and

transmission gears, pulley, v-belts, etc. About that leaves parts, generally are not the main component,

in the feeding part can be said inside spiral leaf, in the output part can be said spiral leaf. Also in the

auxiliary equipment if using a spiral conveyor there is a part called spiral leaf, but strictly speaking, it’s

not ball mill parts.

Performance features:

1. When the diameter of the ball mill is less than 3200mm, its conventional configuration is using rolling

bearing instead of bush sliding bearing, energy saving 10% - 20%;

2. When the diameter of the ball mill is more than 2700mm, its conventional configuration is using slow

driving device for installing liner and maintenance;

3. When the diameter of the ball mill is less than 1500mm, its conventional configuration is monolithic

large chassis, then reduce installation requirements and shorten installation time;

4. When the power of ball mill is less than 110 kW, it uses cage asynchronous motor; When the power

of ball mill is more than 110 kW, it uses wire wound asynchronous motor, when the power of ball mill is

more than 400 kW, it uses high voltage (6 kV or 10 kV) asynchronous motor or the TDMK series high

voltage (6 kV or 10 kV) synchronous motor;

5. Drum feeder, Spiral feeder and Joint feeder are available for meeting different working condition;

6. The gear lubrication mode has grease lubrication, thin oil lubrication and automatic oil mist lubrication

for meeting different working condition;

7.The bearing lubrication has manual and electric grease lubrication pump for automatic lubrication;

8, There are a variety of liner plates type to select. Compared to A series standard type, B series

energy-saving type can save energy 10% - 20%.
