ISO,CE Quality Approved Ball Mill

Dry ball mill introduction:

Dry 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.

Dry ball mill application:

They 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, and more. 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.

Dry ball mill features:

1.Ball mill is an efficient tool for grinding many materials into fine powder.

2.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: dry way and wet way.

Ball mill can be divided into tabular type and flowing type according to different expelling mine to use the

ball mill,material to be ground is loaded into the neoprene barrel that contains grinding media.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.Longer the ball mill runs, the finer

the powder will be.Ultimate particle size depends entirely on how hard the material you're grinding

is and the time how long the ball mill runs.Our ball mills have been used to grind glass, powder food products, create custom varnishes,make ceramic glaze and powder various chemicals.

Dry ball mill working principle:

Ball mill is a horizontal rotating device transmitted by outer gear.Materials are transferred to grinding

chamber through quill shaft uniformly.There are ladder liner and ripple liner and different specifications

of steel balls in the chamber.Centrifugal force caused by rotation of barrel brings the steel balls to a

certain height and impact and grind the materials.Ground materials are discharged through the

discharging board thus the grinding process is finished.
