 Hot saled Intermittent Ball Mill machine

Planetary ball mill introduction:

Wet planetary ball mill grinding 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

One of planetary ball mill’s usage:

Ball mill grinding is the key equipment of beneficiation equipment for grinding after the crushing process, which is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control)

Widely used in the manufacture industries, such as cement, silicate, refractory material, new building material, fertilizer, ferrous metal, nonferrous metal and glass ceramics

Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice

Working principle of planetary ball mill:

This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers

The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment

The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material

After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material

The powder material will be discharged from the grid plate to finish the grinding

Planetary ball mill features:

An efficient tool for grinding many materials into fine powder

Used to grind many kinds of mine and other materials, or to select the mine

Widely used in building material, and chemical industry

There are two ways of grinding: the dry way and the wet way

Ball mills can be divided into tabular type and flowing type according to different expelling mine

To use the ball mill, the 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

The 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, powder various chemicals
