Corn dryer drying system negative pressure operation, equipped with improved heat transfer, heat transfer device directly material drying moisture control convenient, large elasticity of operation, allowing the flow of products has a larger range. Corn dryer in grain drying system in the high temperature mechanical equipment, simple and reliable, simple structure, easy cleaning, low fault rate and continuous operation, low maintenance cost, wide application scope. Corn dryer system are widely used in the activated sludge drying, sewage sludge drying, petrochemical sludge drying, papermaking sludge drying, printing and dyeing sludge drying, tanning sludge drying, drying, municipal sludge drying electroplating sludge, biological fermentation mushroom residue and so on all kinds of high moisture materials such as sludge and all kinds of bad slag drier.

With the continuous rotation of corn dryer cylinder, make some moisture to evaporate, further drying sludge. At the same time, the corn dryer ball cleaning device for sludge group also had broken effect, can improve the drying speed, the dry sludge into low moisture of loose materials, is being exhausted from port discharging sludge dryer, high temperature exhaust gas purification by deodorization equipment emptying after deodorization, fine dust by cyclone catcher, recycling.

The constant development of corn dryer machine industry, industrial demand more and more demand for coal slime dryer, upgrading of corn dryer equipment is a foregone conclusion. Corn dryer convulsions dust removal process, can not only avoid the environmental pollution, reduce the loss of the original burning material and can improve the output of coal slime dryer. Industry development, production and processing varieties of the nature of the material and complicated, corn dryer must gradually became a certain industrial machinery tools.

Corn dryer adopts the advanced drying technology, the binding clouds of slime separation, quickly away and boiling down into loose, after the coal slime dryer feed, feed system under the action of constantly and rotation, increasing heating area is fully mixed with hot air, fast drying material. Corn dryer manufacturing have more advantages, its development technology has been gradually mature and perfect, can well meet the requirements of a variety of industries a variety of levels, moreover also has advantages in price, this will also speed up the development of corn dryer itself to the new market space, give full play to the competitive advantage in the market.

As corn dryer cylinder rotation, namely on the sludge is guide to feed board was promoted to the center of the cylinder, diffused gradually forming curtain material, high temperature air through it, make the sludge preheating and evaporation of water. When sludge on corn dryer, the move to the activities of the grate type on the wing, material and preheating of the grate type wing mixed together, heat to material, make some moisture to evaporate. At the same time, the wing powder material filed, falls, repeated many times, the material and heat flow to convection heat exchange and contact.

The feed plate wall adhesion material cleaning, when cleaning device with cylinder turned vertical corn dryer drag on the back of the circular arc feed plate, the adhesion in the feed board outer wall material cleaning down. Corn dryer models complete, the production equipment is perfect, good environmental protection effect. Water can be 85% or so of the wet sludge dewatering drying become water of less than 10% of the dry powder.

: 1. Reduce the evaporation of the corn dryer load material before entering the dryer, through filtration, separation, or evaporator evaporation dehydration processing, such as can increase the solid content in material, reduce the evaporation of the dryer load, and this is one of the most effective method for drying equipment of energy saving.

2. High efficiency, good drying effect, reduce the coal drying process of all kinds of heat loss

3. Improve the corn dryer inlet air temperature, reduce the dryer outlet flue gas temperature
