Brief Introduction
Micro powder grinding mill is designed by our R&D department on the basis of multiple innovation and testing. It has been proved by thousands of customers that our machine has outstanding features,stable quality, easy operation and maintenance. It is the ideal equipment for fine powder milling.
Scope
HX-GCC Series Micro Powder Grinding Mill is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rockphosphate, Kalium ore. pumice, etc., totally more than 100 kinds of materials.
Working Principle
HX-GCC series micro powder grinding mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.
When the grinding mill is at work, the main bearing and each dial are driven by electromotor of main equipment through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. Then the materials fall into multiple layers and to be crushed and ground continuously to micropowder.
The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the airf1ow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow:the unqualified particle size wi1l fall and return to the mill for being reground while the qualified partic1le size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.
Features
· High Efficiency
Under the same finished final size and the same motor power. The capacity of micro powder grinding mill ls twice as much as jet mill, mixing grinder and ba1l mill, and energy consumption decreased 30%.
· Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year,which is2-3 times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
· High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and s8alcomponents.
· High fineness, flexible adjustment
Tll'efnalfinenessc1fthe grinding materials can be acljustedbetween325 meshes and2500mesh(47-5 micron), and the productf1neness can reach D97≤5µm.
· Environment-friendly
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
· Advanced inte1ligent speed control device
Convenient adjus1ting, more uniform particle size.
