Ultrafine mill is a kind of fine powder and ultrafine powder grinding processing equipment, this equipment is mainly suitable for medium and low hardness, humidity is less than 6%, Mohs hardness below 9 non-flammable and explosive non-metallic materials.
Working principle of ultrafine mill:
When working, the material that needs to be crushed is added to the machine from the feed hopper on the side of the cover shell. It revolves around the vertical axis and rotates itself at the same time. Due to the role of centrifugal force during rotation, the grinding roller swings outward and presses tightly on the grinding ring, so that the blade scoops up the material between the grinding roll and the grinding ring. The purpose of crushing the material is achieved by rolling the roller. Wind selection process: After the material is ground, the fan blows the wind into the main casing, blows up the powder, is sorted by the analyzer placed above the grinding chamber, and the fine and coarse material falls into the grinding chamber for re-grinding, and the fineness meets the specifications with the wind into the cyclone collector, collected and discharged through the powder outlet, that is, the finished product.
The air flow is returned to the fan by the return air pipe at the upper end of the large cyclone collector. The wind path is cyclic and flows in a negative pressure state. The increased air volume of the circulating air path is discharged by the waste gas pipe between the fan and the main engine and enters the small cyclone collector for purification treatment.
Introduction of advantages of ultrafine grinding unit
1, high output, good effect, ultrafine grinding machine adopts hierarchical grinding method, coarse crushing first, after fine powder, extending the grinding stroke, so that the material in the process of flow layer by layer crushing, greatly improve the work efficiency and grinding fineness.
2, preset water cooling device, the upper and lower cavities are set up water cooling layer, the external use of quick connection type joint, easy to connect the water pipe. When working, the water is used, and the high temperature generated during the work is taken away by the circulating flow of water, which not only ensures the original characteristics of the crushed material, but also protects the performance of the machine, and avoids the potential safety hazards caused by high temperature.
3, pulse dust removal device
(1) Pulse dust removal is to increase the method of blowing compressed air to remove the dust attached to the filter bag, according to the size of the equipment will have different groups of pulse valves, controlled by the pulse controller. Open a set of pulse valves at a time, using high pressure air from the inside out to blow back to remove the dust on the part of the bag it controls, while the other bags work normally, at intervals the next set of pulse valves open, and so repeat the cycle.
(2) The pulverized dust is easy to adhere to the bag, if there is no pulse dust removal, the bag will soon be stuck with dust, resulting in poor exhaust, resulting in poor powder transportation after crushing, reduced production efficiency, and will lead to faster temperature rise of the crushing chamber, then you need to shut down to clean the bag, time-consuming and laborious.
(3) Strong cleaning capacity, high dust removal efficiency, small footprint. Prolong cleaning cycle, reduce labor intensity.
4, the addition of air hammer, many Shakron collector will produce material sticky wall, recovery is not smooth, the need to manually knock knock, not only increases the amount of labor, but also causes Shakron appearance deformation, affecting beauty and material collection. The machine is equipped with an air hammer on the outer body of Shaklong, which can automatically knock at regular intervals, so that the material collection is smoother and save time and labor.
5, small size, cost-effective. The machine adopts integrated design, more compact and reasonable, small footprint, more stable center of gravity, under the premise of overall performance improvement, reduce unnecessary investment, make the machine more cost-effective, stronger working ability.
