SBM SCM Series Ultrafine Mill is broadly for micron powder making. The output size can attain 2500mesh (5um). It really is suitable to grind the materials with middle and reduced hardness, moisture under 6%, and also the material should be non-explosive and non-flammable, like: calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite, iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, and so forth. The size in the completed item may be adjusted among 325-2500 mesh.
Significant variety of fineness adjusting.
Large pieces of material crushed by the crusher by the hoist into the storage silo, and then by the vibration feeder evenly, continuously and quantitatively into the host grinding room, into the grinding chamber of the material was shovel shovel, into the roller And the ring was rolling crushed, the fan will blow the wind into the grinding room, blowing powder into the analysis machine, sorting, fail to meet the requirements of the particle size of the powder re-grinding room grinding, qualified fine powder With the air into the finished cyclone collector, fine powder and air separation from the discharge port after the discharge is finished powder.
(1) Because the machine is by means of roller, grinding ring and abrasive impact, friction and material crushing, so the machine running vibration and noise, but the sound is uniform, there should be no abnormal sound, if Found that abnormal sound or host current suddenly rose and long time down not down, you should immediately stop checking.
(2) the feed rate should be uniform, the speed of the feed speed can be based on the host motor current rise or fall or according to the level of air pressure in the pipeline to adjust, in general, the pressure change within the pipeline to adjust the amount of feed is more accurate Reliable, both to make the machine full of performance, high yield, and will not plug the air duct caused by the accident. The method of measuring the pressure is as follows: with a diameter of φ10 mm hose one end of the analysis machine pressure tube, the other end of the U-tube pressure gauge, U-shaped glass tube with color (red or blue and other colors) of water, If the air pressure in the machine is lower than the atmospheric pressure, the height of the liquid level of the two tubes changes, and the height difference is measured. When the pressure of the two tubes is not high, Air pressure.
The principle of using the pressure control feed is: if the feed is too much, more than the milling machine grinding capacity, the remaining material accumulation in the host plug the duct, due to the smaller duct, into the host air volume decreases Small, and the blower from the host, grading machine and other machines within the air volume is still the same, the results of the machine to improve the vacuum, the performance of the U-shaped pressure gauge for the two tube height difference between the larger; and vice versa It is necessary to change the feed rate of the feeder, so that the machine is always in normal operation, as the normal operation of the mill pressure, due to the grinding of the material, the layout of the pipeline and so different, the user can Site determination.
(3) into the host grinding material should be massive, such as powder or mixed with more powder in the block, it will reduce the mill production.
(4) Analysis of the motor with the inverter speed, adjust the control button, you can get a different analysis machine speed, the user should be the size of the finished product to select the appropriate analysis machine speed, the higher the speed of the machine, Fine (the use of the inverter see its instructions).
(5) often check the bearings, temperature rise of more than 60 ° C or abnormal noise should be shut down to check.
(6) the installation of the unit should first test test machine to check the installation of the correctness and reliability, air machine test machine should not be more than two minutes, stop the machine to check the flexibility of rotation, with or without overheating, Loose, the whole machine vibration is too large, after adjustment can be added to try production, one hour and then stop the above items, and the roller device hanging out, check the connection bolts are loose, in particular, need to re-tighten the tight Nuts, no problem can be transferred to normal production.
