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.
