Development Status and Characteristics of Mixed Granulator

Calcium carbonate industry with the overall requirements of the granulator is high thermal efficiency, low energy consumption, simple configuration, easy control, small footprint, safe and hygienic operating environment. At present, the inorganic salt industry using the more common efficient mixing granulator are: rotary tube dryer, rotary indirect heating dryer, disc continuous dryer, air dryer (also divided into pulse air, air rotation, positive and negative pressure two Gas flow drying), rotary flash dryer, rotary drum dryer, spray dryer (also divided into granulation, powder, centrifugal, pressure), vibrating fluidized bed dryer, static vacuum dryer, hot air circulation oven , Rake, pulp vacuum dryer, boiling dryer (horizontal, vertical) and so on.
These highly efficient mixing granulators provide a guarantee for product quality, but there are tailored "dust" problems. As the nano-grade products continue to increase, the original particle size more and more fine, paste material potential moisture content increased, coupled with the enterprise to large-scale, large-scale development, enterprises eager to combine efficient mixing granulator. In particular, some large tonnage products, such as precipitation of calcium carbonate, the current national production of more than 300 million tons, the smallest production line with an annual output of 10,000 tons, 100,000 tons scale to five sets of efficient mixing granulator, Guangxi, a business plan to get 50 Million tons, according to the current level of efficient mixing granulator, regardless of the equipment area or the product after drying the tail gas received "dust" volume is great.
The following are the same as the "
In accordance with the current industry commonly used pulse bag filter, the operating environment is very bad, must take effective measures to be resolved. Therefore, we hope that the equipment development unit focused on two issues, one is the high water content of the paste-like fine objects drying problem, the second is the dry body after the exhaust "dust" industrial health problems. Still in the calcium carbonate industry, for example, more than 200 enterprises in the country, in the efficient mixing granulator selection, the basic use of rotary indirect heating dryer, disc continuous dryer, rotary tube dryer, although the production efficiency is met , Energy consumption and exhaust "dust" are not ideal, into the calcium carbonate business, from the ground to the roof are covered with a layer of white calcium carbonate powder, even in the office tables and chairs is a layer of white, this aspect There are management problems, more importantly, dry after the tail off the "dust" but off. Recently, the industry introduced the United States DuPont produced dust removal equipment, basically solved the problem.
Therefore, the combination of efficient mixing granulator should include: to provide heat source equipment, one or two efficient mixing granulator, tail gas "dust" equipment, hope that equipment manufacturing, research units in the high thermal efficiency, low energy consumption, simple configuration, Easy control and other aspects of the article, in the combination of efficient mixing granulator to make a fuss, service others, develop their own. If the calcium carbonate industry to solve the problem of drying, to achieve a highly efficient equipment, environment-friendly, other varieties of dry problems like to solve.
