Vertical mill for Carborundum pulverizing

Carborundum is very hard to pulverize for its high hardness, but the use is very extensive. Carborundum is mainly used for the production of compact and lightweight construction materials processed. Carborundum has four major application areas, such as: functional ceramics, refractory, abrasive and metallurgical raw materials.
(1) As an abrasive, can be used for abrasive grinding wheel, Whetstone, grinding, sand tile class.
(2) As metallurgical deoxidizer and high temperature materials.
(3) As high-purity single crystal can be used for manufacturing a semiconductor, the manufacture of silicon carbide fibers.

Clirik Carborundum Vertical mill also named as silicon carbide Vertical mill, is a professional grinding machine for Carborundum pulverizing.

Application of Clirik Carborundum Vertical mill:
Carborundum Vertical mill  is the new type grinding  equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Mohs’ 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, rock phosphate, kalium ore, pumice, etc., totally more than 100 kinds of materials.

Structure of Carborundum Vertical mill:
Carborundum Vertical mill mainly consists of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.

Working principle of Carborundum Vertical mill:
After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe. When the Vertical mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. The high-pressure air blower constantly inhales air within the Vertical mill and, in turn, the air flow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall an 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 of Carborundum Vertical mill:
1. High efficiency
Under the same finished final size and the same motor power, the capacity of micro powder Vertical mill is twice as much as jet mill, mixing grinder and ball mill.
2. Long life cycle 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 is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3. 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 seal components.
4. High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
5. Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
