Raw mill is mainly consisting of feeding device, big gear wheel, discharging device, cylinder, grate plate, hollow shaft, liner, driving device and other components. 1. The inlet device is consisting of inlet chute and spiral cylinder. There are lining plates in the inlet chute, which extend the working life of the inlet device. 2.

Overflow Type Ball Mill. Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

(the steel thickness is generally 1/100 of the cylinder diameter, for example ball mill of Φ1500, the steel plate thickness is 16 mm), the material of inlet and outlet hollow shaft is ZG35. 6.The hollow axis adopts the cast steel and the lining can replace, the rotating big gear processes in the way of casting rolling gear.

Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.

Classifier Mill; Ball Mills; Impact Mill; Spiral Flow Jet Mill; Opposed Jet Mill. Opposed jet mills are a type of microniser used for the superfine grinding of a wide range of materials where other forms of mill are unsuitable, particularly in cases where the feed material is hard, already relatively fine, has a low melting point or where high ...

Ball Mill M.D. Engineering. Ball mill is an efficient tool for grinding materials like ores, chemicals, ceramic raw materials paints etc. in to fine powder or fine paste by grinding in a wet way. the ball mill operates by rotating a cylinder with grinding balls like steel, ci, ceramic and pebble balls as grinding media. read more

The structure of the overflow ball mill is basically the same as that of the grid ball mill, but there is no material row in the cylinder end, and the reverse spiral blade is installed on the inner surface of the hollow neck bushing, which can return the pellets and coarse ore blocks in the pulp back to the mill.

The ball mill price is affected by following factors, you can choose suitable cement ball mill acoording to these factors. ... The inlet head and shaft head of the spiral shaft are provided with pig iron cover, which is safe and reliable to operate, and the failure rate is lower than twice that of other competitors. Please be assured to buy.

A concept which has found some application for ball mills is the "angular spiral lining". The circular cross-section of a conventional mill is changed to a square cross-section with rounded corners by the addition of rubber-lined, flanged frames, which are offset to spiral in a direction opposite to the mill rotation.
