Product Description

1.The dryer machine produced by our company is the most commonly used rotary drying equipment, widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine, mining, environmental protection and other fields.The clay of cement industry, parts high water content material of chemical industry, drying of bentonite, drying of grain etc,all of them requires drying of the dryer.

2..With the improving of the national environmental awareness, bring the municipal sewage, oilfield sludge of the processing industry rapidly development, the disposal and development utilization problems of  sludge have attracted more and more attention, it is possible to the sludge drying treatment.

3..Our company directly against  the sludge which have high moisture content, high viscosity, high water holding capacity and lower heating values characteristic materials,Specially research and designing the sludge exclusive use for drying equipment,and made special design in the dryer internal structur, not only improve the thermal efficiency,but also effectively avoids the adhesion and excessive drying of the sludge in the drying machine.Rotary dryer has single cylinder, double cylinder and three-cylinder dryer, it is used in different industries and different materials.

Suitable materials

Working Principle

1.Wet material which needs drying is feeded into the hopper by the belt conveyor or bucket elevator, and then the hopper feeder enters to the feeding end through the feed pipe. The slope of the feeding pipe is greater than the natural dip angle of the material so that the material flows smoothly into the dryer. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line.

2.The material is added from the higher end, the heat carrier enters from the lower end, and countercuttent contact with the material, and the heat carrier and the material flow into the cylinder together get to co-current contact. With the rotation of the cylinder, the material moves to the lower end by gravity action. When the wet material moves forward in the cylinder, the heating of the heat carrier is obtained directly or indirectly, so that the wet material is dried, and then sent out at the discharging end by the belt conveyor or chain bucket conveyor.

3.A plate (lifting plate) is arranged on the inner wall of the cylinder, and the function  is to copy and then scatter the material so as to increase the contact surface between the material and the airflow, to increase the drying rate and promote the material advance. Heat carriers are generally divided into hot air, flue gas, furnace in fluid bed, etc.. The heat carrier usually needs cyclone dust collector after the dryer to collect the material in the gas. If you need to further reduce the amount of dust contained in the exhaust gas, it should also be discharged after a bag filter or a wet dust collector.

Advantages

1.Higher level of mechanization，greater production capacity.

2.Good dust sealing performance, convenient maintenance.

3.Stronger adaptability of the materail, the operation is stable and convenient.

4.Large amount of processing, less fuel consumption, low drying cost.

5.Outlet temperature is low, and the heat efficiency is high.

6.It can according to the different property of the materail to change the operating parameters.

Maintenance

The Drying machine as a kind of drying equipment which to dry the large quantity of the materails, good operation of the equipment, not only to ensure the normal production, but also can be appropriate to extend the service life equipment, reduce production costs, so the correct operation and maintenance of the equipment is very necessary. The regular cleaning, maintenance and maintenance of the dryer will help to find out the problems in time, solve the potential failure, reduce the downtime, and ensure the normal production stability.
