Energy-Saving Ball Mill
Introduction:
Energy-Saving 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.
Energy-Saving Ball Mill
Application:
Energy-Saving Ball Mill 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.
Energy-Saving 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.
Energy-Saving Ball Mill Working
Principle:
The Energy-Saving 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.
