Product Name: Limestone Micro Powder Grinding Mill Model NO.: HGM Series Condition: New Materials: Gold Application: Construction Rotationl Speed: 20-22r/min Motor Power: 22KW Motor Type: AC Motor Type: Handling Machinery Color: Any Capacity/(T/H): 0.4-7.5 Finished Size/Um: 5-47 Input Size/Mm: ? 20 Warranty: 1 Year Trademark: Dingbo Machinery Transport Package: Standard Container Specification: Standard Origin: Shanghai, China HS Code: 8474209000 Product Description Detailed Description:Our super thin grinding machine is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as diatomite, calcite (calcite carbonate, calcium carbonate), chalk, limestone, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 0.047mm (47 micron) and 0.005mm (5 micron).Ultrafine Grinding Mill Features and Benefits:1. High efficiency In same condition of finished particle size and power of motor, the output is 40% higher than airflow mill and whisk mill.2. High using rate of the quick-wear part In same condition of material and finished particle size, the lifetime of the quick-wear part is longer than that of impact crusher and turbine crusher. It can be generally one year.3. High safety Because there are no axle tree and bolt in the grinding antrum, there will be no wearout of bearing and sealingpart, also no loose of bolts.4. Environmental protection It will lighten pollution and noise by using dust cleaner and muffler, which achieves environmental protection requirement.Ultrafine Grinding Mill Working Principle:HGM Series Micro Powder Gring Mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.The main bearing and each dial are driven by electromotor of main equipment through reducer, and numbers of ring and rolls which are rolling in the ring channels are driven by dial through plunger. After being crushed by hammer crusher, the big materials become small ones and they are sent to the storage bin by elevator. The electromagnetic vibrating feeder sends them to the edge of dial by centrifugal force, and ground by the grinding rings and rolls. Then the materials fall into the second and third ring and crushed and ground. The high pressure centrifugal blower inhales air from the outside and blow the materials which are ground in the third ring to powder Seperator. The rotating turbo in the powder Seperator makes the coarse materials return to the mill and reground, while the fineness mixes with the air and be drawn to the cyclone and be discharged from the discharging valve which is in the bottom of it. The air which mixed with very little fineness are purified by impulse dust catcher and discharged by blower and muffler.High Quality After-sales service (Freeing our customers from worries)Tracking service for one year, and lifetime warrantyMaintenance and replacement serviceReminding for the service life of the wearing partsInstallation guideWhole process and guidance.Technical DataModelHGM80HGM90HGM100HGM100AHGM125Ring Diameter/mm80093010351300Ring Number/ pcs33~4344Roller Number/ pcs2124~322734~3640~44Main Shaft Speed /r. p. min230~240200~220180~200135~155Input Size/mm<=20Finished Size/μ m5-47(325~2500)Capacity t/h0.5-4.50.6-6.50.7-71-8.51.5-12Outlet Size LXWXH/m13.9*4*6.214.7*4.8*7.218*4.6*8.614*9*10.25Power /Kw145-165185-204263263-290380-430
