26 Rollers Ultrafine Grinding Mill With 600-2500 Mesh Fineness Range and Higher Output

Ultrafine Grinding Mill is mainly used to grind non-inflammable, non-explosive and brittle materials with Moh's hardness less than 6, such as calcite, calcium carbonate, limestone, dolomite, gypsum, kaolin, talc, mica, feldspar totally more than 100 kinds of materials.

The powder fineness can be adjusted between 600 meshes and 2500 mesh, by adjust the classifier rotation speed. and the product fineness can reach D98≤5μm.

In order to protect the ultrafine grinding mill, you need to know how to start and stop the ultrafine grinding mill:

How to stop the ultrafine grinding mill:

1. Stop the crusher until there is no material in the crusher

2. Stop the elevator until there is no material in the bucket.

3. Stop the feeding conveyor

4. Stop the mill until there is no material in the mill. This does good to the next mill start and protection of the mill.

5. Stop the blower after stopping the mill in 30 seconds, and put the extra air pipe valve on the “Close” position.

6. Stop the Classifier.

7. Stop the pulse-jet collector

How to start the ultrafine grinding mill:

1. Please ensure the voltage should not be less than 360V.

2. Please wipe out all the liters, and all the bolts and nuts are all connected tightly.

3. Make sure the belt tightness is proper, and move the belt wheel by hand, and mill wheel can rotate flexibly.

4. Ensure the valve handle in the blower air-in pipe is on the “close” position.

5. Make sure the tightness of the elevator chain is ok.

6. Regular lubrication should be done according to the lubrication table, and ensure there is no grease or oil leakage.

7. Feeding size into to the mill should be less than 10mm

8. Make sure the motor rotation direction is correct

9. Any metallic material should not be in the raw material. The users had better install the iron eliminator by themselves.

After the installation, please do the test without any material. Please note: the ultrafine grinding mill should run less than 2 minutes without any material in the mill. And then stop the ultrafine grinding mill to check whether every part runs well (no overheating; no bolt looseness, no higher vibration for the ultrafine grinding mill). After the test running, please feed some material into the ultrafine grinding mill for grinding one hour. And then check whether every part is ok or not, if yes, the ultrafine grinding mill can ran regularly.

Structure of Ultrafine Grinding Mill:

The ultrafine grinding mill has the folllowing components: crusher, elevator, hopper, feeder, classifier, mill, collector, blower and electric control cabinet. And delivery and installation of the whole micro powder grinding mill system is simple and easy to be completed. As the ultrafine grinding mill has been tested in the factory, so the ultrafine grinding mill can run as soon as the installation is completely.

The motor drives the ultrafine grinding mill shaft and roller table go around by the V-belt. The roller will rotate and revolve against the ring, which will make the material into powder from the top level to the bottom level. Classifier includes motor, coupling, shaft, vane wheel and housing. The motor controls the classifier wheel rotation speed. The faster the rotation speed, the finer the powder and vice versa. The blower includes housing, vane wheel, shaft, motor and support.

Special Features of Ultrafine Grinding Mill:

1. Perfect contact between rollers and ring: The arc or curved surface increases their effective working surface and improves the crushing efficiency. The rollers and rings contact surface and shapes should be consistent and tightly fit, which is good to the production of fine powder.

2. Improved hardness of rollers and rings: this not only guarantees longer working life, but also the powder is not easy to be contaminated.

3. Rotation speed of central shaft can be adjusted according to customer’s requirement.

4. Pulse-jet Collector: 99.99% of the ultrafine powder can be collected, which is also environment-friendly.

5. Constant temperature control system is adopted and the whole design is also improved, so various additives can be put into the mill to improved the application range of powder.

6. High quality casting technology to prolonger the working life of roller and ring.
