Micro Powder Grinding Mill with Precise Fineness Control and Higher Whiteness

In order to protect the micro powder grinding mill, some points should be put into mind:

As the raw material is ground between the roller and ring, the micro powder grinding mill noise is a little higher. This is normal for the micro powder grinding mill and the noise should keep at a same level. If any abnormal noise arises or the mill motor current increase suddenly and difficult to decrease, please stop the mill and check carefully. Maybe there is crack or iron in the grinding house.

For the feeding rate, please make it at an even rate. If faster, mill will be blocked; if slower, the production capacity will be lower. The feeding rate can be adjusted according to the rise and fall of the mill motor current. Most of the raw material should be the blocks or lumps; if there is more powder in the raw material, the production capacity will be lower.

The micro powder grinding mill classifier motor is controlled by inverter. The classifier rotation speed can be adjusted by the inverter. The higher the rotation speed, the finer the powder; the lower the rotation speed, the coarser the powder. Check the bearing frequently. The temperature of the bearing should be less than 80℃. If any abnormal noise arises, please stop the mill and check carefully.

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

Structure of Micro Powder Grinding Mill:

Micro powder grinding mill has the advantages of higher output, low investment and simple grinding technique. The mechanical and chemical reaction in the process of grinding is also good to improve powder activity. Generally speaking, one engieer from factory can do installation and test running work.

The micro powder 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 micro powder grinding mill has been tested in the factory, so the micro powder grinding mill can run as soon as the installation is completely.

Special Features of Calcite 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.
