Large Capacity And Crushing Ratio Ball Mill Grinder Long Working

Ball Mill Grinder Introduction:
Grinding operations are required in industrial sectors such as
mineral processing, building materials, cement, coal, chemical,
electric power, light industry and metallurgy. Ball mills, vertical
mills, jet mills and other mills are one of the important equipment
in these industrial sectors. .
Ball mills are the most widely used. The main component of this
type of pulverizer is a slowly rotating cylinder, which contains
grinding media. Because the ball mill has a simple and firm
structure, reliable operation, simple maintenance and management,
and long-term continuous operation, It has strong adaptability to
materials, large crushing ratio (up to 300 or more) and large
production capacity, so it can meet the needs of modern large-scale
industrial production.
The ball mill is composed of a horizontal cylinder, a hollow shaft
for feeding and discharging materials, and a grinding head. The
cylinder is a long cylinder with a grinding body inside the
cylinder. The cylinder is made of steel plate, and the steel liner
is fixed to the cylinder. Generally, it is a steel ball, which is
packed into the cylinder according to different diameters and a
certain proportion. The grinding body can also be made of steel.
Choose according to the particle size of the grinding material. The
material is loaded into the cylinder by the hollow shaft at the
feed end of the ball mill. When the cylinder of the ball mill
rotates, the grinding body is attached to the cylinder liner due to
inertia, centrifugal force and friction. Carried away by the
cylinder, when brought to a certain height, it will be thrown down
due to its own gravity. The falling grinding body will crush the
material in the cylinder like a projectile.
Working Principle:
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.
1. This ball mill, 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.
