Stable Running Ball Mill Grinder
Henan zhongke ball mills
Ball mill is the key milling equipment after materials has been
crushed. It is widely used in Cement, silicate, new construction
material, refractory material, ferrous metal and nonferrous Metal
as well as ceramics. It is widely applied to grind ores in dry or
wet process. Working principle: The ball mill is horizontal
cylindrical rotation device, driven by brim gearwheel. There are
two Chambers and grid. Material goes into the first chamber through
the feeding inlet. Inside the First chamber, there are stage liners
and ripple liners as well as steel balls. The shell rotates So as
to generate electricity, and this force brings ball to a certain
height and then balls drop Down by gravity, the impact is the
grinding force to the material. After the primary grinding,
Materials go into the second chamber through segregate screen. In
the second chamber, there are Flat liners and steel ball, after the
secondary grinding, material is discharged from the Discharging.

Ball Mill grinds material by rotating a cylinder with steel grinding balls,
causing the balls to fall back into the cylinder and onto the
material to be ground. The rotation is usually between 4 to 20
revolutions per minute, depending upon the diameter of the mill.
The larger the diameter, the slower the rotation. If the peripheral
speed of the mill is too great, it begins to act like a centrifuge
and the balls do not fall back, but stay on the perimeter of the
mill. The point where the mill becomes a centrifuge is called the
"Critical Speed", and ball mills usually operate at 65% to 75% of
the critical speed.
Ball Mill Application:
are generally used to grind material 1/4 inch and finer, down to
the particle size of 20 to 75 microns. To achieve a reasonable
efficiency with ball mills, they must be operated in a closed
system, with oversize material continuously being recirculated back
into the mill to be reduced. Various classifiers, such as screens,
spiral classifiers, cyclones and air classifiers are used for
classifying the discharge from ball mills. Ball mill is an
efficient tool for grinding many materials into fine powder. The
ball mill is used to grind many kinds of mine and other materials,
or to select the mine. It is widely used in building material,
chemical industry, etc. There are two ways of grinding: the dry
process and the wet process. It can be divided into tabular type
and flowing type according to different forms of discharging
Ball Mill Features:
1) is an efficient tool for grinding many materials into fine
2) The ball mill is used to grind many kinds of mine and other
materials, or to select the mine
3) Ball mill is widely used in building material, and chemical
4) There are two ways of grinding: the dry way and the wet way.
5) Ball mill can be divided into tabular type and flowing type
according to differentexpelling mine
6) To use the ball mill, the material to be ground is loaded into
the neoprene barrel that contains grinding media.
7) As the barrel rotates, the material is crushed between the
individual pieces of grinding media that mix and crush the product
into fine powder over a period of several hours.
8) The longer the ball mill runs, the finer the powder will be.
9) Ultimate particle size depends entirely on how hard the material
you're grinding is, and the time how long the ball mill runs.
10) Our ball mills have been used to grind glass, powder food
products, create custom varnishes, make ceramic glaze, powder
11)Complet ely enclosed welded design in high-grade steel.
- Direct drive via bearing journal with top-mounted gearbox.
Motor connected to gearbox via a V-belt drive.
- Product discharge via slots located around the periphery of the
Ball mill Working Principle:
The ball mill is a horizontal rotating device transmitted by the outer gear. The
materials are transferred to the grinding chamber through the quill
shaft uniformly. There are ladder liner and ripple liner and
different specifications of steel balls in the chamber. The
centrifugal force caused by rotation of barrel brings the steel
balls to a certain height and impact and grind the materials. The
ground materials are discharged through the discharging board thus
the grinding process is finished.
Specifications of Ball Mill
NOTICE:ANY CHANGE OF THE TECHNICIAL DATA SHALL NOT BE ADVISED
Energy saving ball mill is applicable for grinding all kinds of
mines and other materials, widely used in mineral separation,
building material and chemical industries, including dry-type ore
grinding and wet-type ore grinding. According to different
discharging methods, it is divided into grate ball mill and
overflow ball mill.
It is a kind of key equipment for milling the materials into
powders after they are crushed. It is widely used for cement, the
silicate product, new type building material, fire-proof material,
chemical fertilizer, black and non-ferrous metal, glass, ceramics
and soon, and can make the dry and wet milling on all kinds of ores
and other grindability materials .
It is horizontal type and cylinder rotating device, has two cabins,
grate energy saving ball mil, and its outside drives along gear.
The material enters spirally and evenly the first warehouse of the
milling machine along the input material hollow axis by input
material device, In this warehouse, there is a ladder scale board
or ripple scale board, and different specification steel balls are
installed on the scale board, when the barrel body rotates and then
produces centrifugal force, at this time, the steel ball is carried
to some height and falls to make the material grinding and
striking. After grinding, coarsely in the first warehouse, the
material then enters into the second warehouse for regrinding with
the steel ball and scale board In the end, The powder is discharged
by output material board and the end products are completed.
The 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 cylinder is
wearable well and bears wearable lining board. This machine runs
steadily and works reliably.
