Introduction of Phosphate rock ball mill

Phosphate rock ball mill is an efficient tool for grinding many materials into fine powder. The Phosphate rock 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.

Structure of Phosphate rock ball mill:

Phosphate rock ball mill is composed by feeding part, discharging part, rotation part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The rotation big gearwheel is made by cast hobbling processing and the drum is equipped with wear-resistant liner, which has good wear-resistance. The Phosphate rock ball mill is with stable and reliable working condition. 

Working principle of Phosphate rock ball mill

The Phosphate rock ball mill is horizontal cylindrical rotation device, driven by brim gear wheel. There are two chambers and grid. Material goes into the first chamber through the feeding inlet. Inside the first chamber, there are stage liners and ripple liners as well as steel balls. The shell rotates so as to generate electricity, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball. After the secondary grinding, material is discharged from the discharging mouth. Then the whole grinding process is ended.

The production line of Phosphate rock ball mill

Features of Phosphate rock ball mill

1. Low energy consumption: our Phosphate rock ball mill adopted high advanced energy-saving technology and classification technique; as a result, our production line can save over 40% energy for producing same quantity materials.

2. Several times of classification could be obtained:

Finished product fineness after first time classification: 300-2500mesh; if our Phosphate rock ball mill is equipped with a second classification system, the finished product fineness after second time classification would be 6,250mesh (d97≤2um).

3. Adopted highly advanced self-diffluent classification system:

(1) The classifiers in Phosphate rock ball mill have a precise classification, so the produced materials have uniform fineness;

(2) High classification capacity: 100t/h;

(3) Low energy consumption: For classifying the same quantity of raw materials, a classifier in Phosphate rock ball mill can save about 40% energy comparing with traditional ball mills.

(4) High classification efficiency (50% higher than classifiers in traditional grinding mills)

4. Scientific grinding medium enable us to produce large quantity superfine particles.

5. Different lining boards and grinding mediums are available for milling different materials, so as to guarantee the purity and whiteness of finished products.

6. Scientific machine structure enables a lower investment cost;

7. Negative pressure production condition gives a good production environment; 

8. High annual production capacity: 5-500 thousand tons.

Application of Phosphate rock ball mill

Our Phosphate rock ball mill is used to grind many kinds of mineral ores and other materials, or to select mine. Phosphate rock ball mill is also widely used in the manufacturing industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics.
