Six classified techniques of SCM Ultrafine Mill .

1.Classification according towards the impact

Light, heavy

2.Classification in accordance to the length

(1)Quick mill: It really is named short mill or ball mill once the L/D is beneath two. A popular mill with a single chamber is used in coarse grinding or key grinding. Moreover, two to three ball mills can be utilized in tandem.

(2)Medium mill: It could be referred to as medium mill when the L/D is about three.

(three)Extended mill: It truly is termed prolonged mill or tube mill once the L/D id over four. The within in the medium mill or lengthy mill is pided into two to 4 chambers, which is broadly used in the cement plant.

3.Classification according on the shape with the grinding medium

(one)Ball mill: The grinding mediums are mostly steel balls and steel section, this kind of mill is most normally used.

(two)Rod mill: The grinding medium put in to the mill is the steel bar whose diameter is concerning 50mm and 110mm. The L/D in the rod mill is usually in between 1.5mm and 2mm.

(3)Ball rod mill: This sort of mill typically has two to 4 chambers, the primary chamber is set up cylindrical steel bars as grinding medium, the other individuals are put in with steel balls or steel segment.

The L/D of this mill need to be 5, the ratio of your length with the bar chamber as well as the effective diameter in the mill should be concerning one.2 to 1.5, the bar length is 100mm shorter than the bar chamber effective to parallel arrangement and also to steer clear of crossover and disorderly stick.

(four)Gravel grinding mill: The grinding medium within the mill are gravel, pebbles and ceramic balls. It employs granite and ceramic resources since the liner. It truly is applied during the manufacturing of your white or shade cement and ceram.

4.Classification according to discharging methods

(1)Tail discharge kind: grinding supplies are fed from one particular end of your mill then discharged from the other end.

(two)Middle discharge form: grinding resources are fed through the two ends after which discharged from your middle. This kind of mill equals to two ball mills used in parallel, which enables equipment to become far more compact and simplifies the course of action.

(three)Head discharge style: According to discharging solutions, it may be pided into quite a few types like grate mill, overflow discharging mill, peripheral discharging mill at the same time as wind discharging mill.

5.Classification in accordance to transmission

(one)Center drive mill: The motor drives the mill to rotate by driving the hollow shaft of the mill discharging end through the reducer. The shaft extension in the reducer along with the centre line of your mill are in the very same straight line.

(2)Edge drive mill: The motor drives the mill’s cylinder to rotate by driving the big gear fixed from the discharge cylinder by the reducer.

6.Other classifications

According towards the craft, it could be pided into dry mill, wet mill, intermittent mill and continuous mill too. Compared with the intermittent mill, the continuous one is of high yield, the current consumption per unit weight of product is low, the mechanization degree is high as well as number in the operators is small. However, the investment cost in the infrastructure is big and also the operation and maintenance are complicated. At present, the intermittent mill is rarely applied but often applied in lab test grinding.
