HD 1720 super-large grinding mill is a large one which has been designed and improved by introducing advanced techniques at home and abroad on the basis of 6R series mill.
ONE.It has the following features:
1. high output､Iow energy consumption:Its output is equivalent toφ1250 vertical mill’s, but energy consumption is three fourths of vertical mill’s. and Its output is equivalent to 6 sets 4R3216 raymond mill’s, but energy consumption is three fourths of ordinary raymond mill’s.
2. the grinding Mill covers an area of 153 square metres, save infrastructure investment.
4. Using double whirlwind collector, Collection efficiency is Increased by10-50% collection rate than the single .
5. with the Turbine Classifier, product fineness can be arbitrary adjustment between 80-600 mesh.
6. increase Shovel blade :sent the materials into the middle of roll grinding and grinding ring in maximum.
7. adopt Impulse precipitator, save energy and pollute less, Its collection efficiency over 99.9 per cent.

TWO．HD 1720 super-large grinding mill is widely used in the following projects
1、Large desulfurized projects
Coal-fired power plants now widely used the technology of sulfur in combustion decarbolize, burning sulfur removal technology is refers to the combustion in with desulfurization simultaneously. It besides desulfurization reduce sulfur dioxide emissions, can still improve thermal efficiency, reduce fuel consumption, the relatively mature have injected calcium technology, furnace furnace technology is simple, injected calcium low cost.It has the following advantages: 1, desulfurization rate reaches as high as 95%, calcium utilization of 90%. 2, limestone as desulfurization absorber its source widely and low price.
Our company produce, the HD 1720 super-large mill is widely used in power plant project engineering, desulfurization their yields: processing 80-200 mesh calcium carbonate per hour with 10-20 tons. Our company has successfully for the henan nanyang, sanmenxia, xinjiang urumqi etc provides equipment plant
2、Large manganese powder processing projects
Carbonic acid manganese is mainly used in the electrolysis manganese, metallurgy manganese, desulfurization catalyst, wire, porcelain glazes materials, etc. The electrolysis manganese is also producing stainless steel, high strength steel alloy, copper mangansese alloy and other important elements.
Metallurgical manganese in special steel developing its proportion is more and more big, the purpose is very extensive.
Manganese dioxide is a very battery industry total to raw material, also be a kind of very good catalyst, also be a kind of performance comprehensive excellent purifying water filter material, USES very extensive.
My company according to the need of the market, around improve manganese powder production, do a lot of work:
(1), use the increase of host method to improve dynamic pulverizing capacity.
(2), with large air blower to improve pneumatic conveying capacity.
(3), double whirlwind collector and increase the diameter of a method to improve transport collection ability. (4), uses the passing high grade machine to improve classification ability.
Through the above series improvement measures have achieved remarkable effect, yield got the large scale enhancement.
Processing carbonic acid manganese (80-100 mesh) output May 10-14 tons/hour, processing the output
(80-100 mesh) for 16-22 tons per hour.
3、 highway asphalt modified engineering
The asphalt pavement is one of the most extensive road construction by senior road. And among them main raw material asphalt pavement is a kind of complex polymer hydrocarbons, adding mineral materials in asphalt carbonate powder will greatly improve the asphalt pavement resistance cranes and natural factors of automobi damage ability. Make road surface smooth, impervious, durable. The HD 1720 super-large grinding mill function efficient machining calcium carbonate powder, is the most ideal asphalt modified engineering equipment.
