High Efficiency Ore
Grinding Mill Machine and Various Metallurgical Model Ball Size
and Features​
Ore Ball Mill introduction:
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 *0 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 *5% to *5% of the critical speed.
Ore Ball Mill Application:
Are generally used to grind material 1/4 inch and finer, down to
the particle size of *0 to *5 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 material.
Ore Ball Mill Features:
1) Is an efficient tool for grinding many materials into fine
powder.
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
industry.
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.
*0) Our ball mills have been used to grind glass, powder food
products, create custom varnishes, make ceramic glaze, powder
various chemicals.
*1) 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
drum.
ore 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.
