It can produce powder form various non-flammable and non-explosive minerials with Mohs hardness below 6, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnesite, meerschaum, diatomite, barite, gypsum, alunite, graphite, fluorite, floatstone, ect.
Mills motor lets rotary table circumgyrate by speed reducer, rollers are driven by the connection axes of rotary table. Big materials are broken into small ones by hammer-crusher, then put into the storage cabinet by bucket elevator, materials are equably transferred to the middle of the rotary table by vibrating feeder. Materials can be disseminated to the circle by centrifugal effect, then fall into the ball-race and grinded into powder. The materials fall into the second and third floor after the first crush. High-pressure centrifugal blower inhales outer-air which can put the grinded powder into separator. Worm wheel of separator makes bigger particle fall into grinder chamber again, and the smaller particles go into the cyclone collector and the finest powder are discharged by discharge-opening as finished product.

Chinese patented product with international advanced technical levelstraight centrifugal grinder, the most new-type thick powder grinder is designed in a totally new way on the basis of producing application experience after our company experts on the powder equipment researching with great concentration for a long time , thus open new era where industry mill is high-efficient and low energy consumption of the powder through concentrating on studies
Key feature (Compared with the Raymond Mill, there are the following advantages)
Save The amount of energy consumption which the straight centrifugal grinders
blower consuming is only 6% of mill, but Raymond Pulverize is 81%. In addition, the
consumed energy when the spiller slide the stone occupy whole energy is 25%, but
straight centrifugal grinder is no exist this consume.
High-efficient In the same condition, the grinding roller of straight centrifugal
grinder can be through a large 2.3 times area than Raymond Pulverize .
High-using rate Grinding roller and grinding ring of Raymond Pulverize are sunken in middle parts, so the metal amount that discarded is only 35% of original weight, but materiel in straight centrifugal grinder fall from top to bottom, so the metal amount can reach a high to 55%.
Accident insurance If bolt or iron ore fall into the Raymond Pulverize, this will conduce to breaking shovel, roller suspender transmutation. But straight centrifugal grinder will not appear such condition.
Well using against high hardness and hard-process material Some high-rigidity material, such as carborundum, corundum, zirconium, the output will fall down because the grinding roller and grinding ring of Raymond Pulverize are sunken in middle parts. But in straight centrifugal grinder, it skives material up and down equably, so the output shows much more stabilization.
Wet production Water is allowed using in Straight centrifugal grinder.
Occupation of area is small It does not need to allocate whirlwind separator and a lot of pipelines . etc, so the occupation of land space is small.
This machine applies to grind material into thick powder. Its mainly used in the mining, construction materials, chemical, and metallurgy. Can be pressed various kinds of not flammable and not explosive supplies crushed, for example, carboundum, and Zircon sand, Quartz, Granite, Barite, Marble, Limestone, Steatite, Plaster model, Scoria, Chinaware, Glass. Can crush material below scale 9.5 of Mohs hardness.
Among the working process, motor brings along milling wheel rack to circumgyrate through trigonometry wheel and center axle. That axle hoist at rubbing roller hanger to rub through bearing roller rub roller hanger while rotating at the same time cross arm, roll along the round while rubbing the roller. The cubic supplies is separated by umbellate hammer and plate, fall symmetrically between the roller and ring. And after pulverizing arranging from cannulation underlayer. The dust removal air blower make minus-press for the inlet and outlet. There is no dust contamination and at the same time it debars the quantity of heat in the machine.
Production with water: the comminution process is almost the same as dry production. The difference is: comminution with water, and the separate quomodo with water. This can be designed by clients need
High pressure micro powder mill

TGM system super-pressure trapeziform mill
Compared with traditional grinding mill, this products are of small land-covered area, lower power consumption, longer service lives, economical wearing parts, and higher performance cost ratio. Numbers of patented technologies, such as trapezium working surface, flexible connection, roll linked pressure boost, and the outfit of the high-efficient centrifugal blower, which make TGM be in a leading level of the world.
1 The ladder-shaped roller and grinding ring improve crushing efficiency greatly. The roller and grinding ring are designed in inverted trapezium with different diameter, which reduce the materials slip velocity between roller and grinding ring, extend grinding time, and enhance crushing effect.
2 The press spring with balancing pressurized function. The symmetrical roll assembly is connected by horizontally placed spring rod. When the large material touches the roller assembly, to keep balance, the radial force may pass to the roll assembly that is plane of symmetry through spring rod. However, the radial force resulted from traditional grinding mill totally passes to the main shaft only, which reduce the service life of main shaft and bearing.
3 The forming resilient joint brings smooth and steady performance. The powder concentrator is connected with main engine through several shaking-reducing springs, then it is sealed up by flexible belt, which reduce vibration and noise, and avoid resonance.
4 The powder concentrator impeller enhances powder precision and high-density product. Good practice dictates that under uniform spindle speed, to enhance the density of impeller is to enhance the fineness of finished product. In other words, when it is unnecessary to alter the fineness of finished product, the spindle speed of high-density impeller is lower than the low density one, thus reduce resistance to air flow and increase production.
5 The outfit of the high-efficiency and energy-saving centrifugal induced draft fan. The efficiency of prismatic blade equipped on the traditional machine is only 62%, but the efficiency of the energy saving induced draft fan whose impeller and blade are both stamping is 83%.
6 Impeller adjusting device brings more convenience. The clearance between housing and powder concentrators blade front end also effects fineness. This patent technology is convenient to adjust the clearance.
R-high pressure grinding mill
The machine (also called Raymond Grinding Mill) is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceramics, whose Mohs hardness is below 7 and humidity does not exceeds 6%. They are all non-inflammable and non-explosive stuff. The product size is adjustable as required in the range of 100-325mesh. Now this series have a high ratio in home market. They are popular with the cosmic company, the mineral factory. The powder is extremely fine.
Load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded.
After being grinded, the stuff is to be routed to the sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the product cyclone collector together with airflow and is expelled from the powder output pipe as product.
In the grinding chamber, since the stuff may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work under negative pressures, the increased airflow is guided to the deduster anew sequentially to the atmosphere after purification.
