Characteristics of superfine jet mill

The ultra-fine pulverizer is uniquely designed with a grading chamber and a grading wheel, and the powder particle size is averaged. So today, the jet mill manufacturer will introduce the unique features of the ultrafine mill.

The uniquely designed classification chamber and the vertical classification wheel with variable frequency speed regulation can classify the product particle size at low rotation speed without the need to configure a screen. The recurrent feeding structure not only strictly limits "large particles" but also avoids over-crushing, so the product particle size distribution is narrow and the particle size is average. The use of grading wheel classification avoids the phenomenon that powders with more than 150 mesh are difficult to pass through the sieve.

ultrafine grinding machine how maintenance:

1. The grease change period of screw feeder is 4000 hours, and common calcium-based grease is added.

2. When the new machine is running, the transmission belt is easy to stretch, so pay attention to adjust the proper tightness of the belt to ensure the working life of the belt.

3. Vulnerable parts should be checked frequently and replaced in time to ensure the production quality and output.

During the production process, the temperature rise of the bearing must be checked frequently. When the temperature rise exceeds 50 ℃, the machine should be shut down for inspection to find out the cause and eliminate the fault.

5. The main engine and graded movable bearings are grease lubricated, using No.2 special grease, with a degree of 265-295.

6, blades, linings should often check the wear, if wear, the yield decreased, the particle size coarser found after wear and replace.

7. The grease change period of the bearing is 2000 hours, and the filling amount of grease is 1/2 (upper measurement) or 3/4 (lower measurement) of the space in the bearing cavity. Do not fill too much grease, otherwise the bearing temperature will be too high.

Superfine pulverizer crushing temperature is low

Because it avoids the phenomenon of "over-crushing. The crushing chamber does not generate excess heat. At the same time, an air duct is provided at the feed end of the crushing chamber (cold air can be connected if necessary). Because of the presence of induced wind, the temperature at the time of crushing is taken away by the induced wind, and the jacket of the crushing chamber is increased by the reincarnation water jacket device to further reduce the temperature generated by crushing.

Full blockade of negative pressure lessons, powder in the crushing process does not occur any leakage, no environmental pollution, noise is small;

Fillet design, using quick assembly connection, easy to remove and install, easy to clean.
