"Printing and dyeing sludge contains a large number of chemical residues, with high proportion of inherent water, is very difficult to dehydrate. Its composition is very complex, with high content of harmful substances and a certain degree of stickiness. After the mechanical filter, the sludge moisture content is still as high as 75 ~ 85%. However, the organic components in printing and dyeing sludge is very high. The calorific value of dry sludge can reach 2000kcal/kg, about 30% - 50% coal. With considerable energy use value, the dry sludge can be mixed with coal as boiler fuel, resulting in economic benefits. ZJN Drying equipment can maximize this benefits.
General printing and dyeing enterprises are set up a large number of flue gas flue gas, ZJN can use the boiler flue air to dry sludge below 30% moisture. And the dry sludge will be small particles. It will greatly reduce the sludge storage and transportation costs and pollution risks.

Product Info: Rotary Drum Dryer also known as a rotary kiln, is employed to reduce or minimize the moisture content of agro and forest waste, it is done by bringing it into direct contact with heated gas. The rotary dryer is made up of a large, rotating cylindrical tube. The dryer discharge end is lower than the material feed to convey the material through the dryer under gravity. Rotary Drum Dryer is suitable to dry raw material which contains high moisture up to 50% and more. JK make CE Certified Rotary Drum Dryer is special designed to reduce or minimize the moisture content of agro and forest waste to 10% or less for briquetting, JK Rotary drum dryer combines the function of drying and cooling, thus save 30-50% energy. What kind of materials do Rotary Drum Dryers process? Rotary dryers are known as the replacement of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include are typical material rotary dryers process include agricultural by products & Waste, animal feeds, animal waste, Forest Waste, Paddy Husk, coconut Shell, bio solids, concentrates, municipal sludge & municipal waste. Types of Rotary Dryer MODEL NO. PRODUCTION POWER REQUIRED JKRTD 3000 kg/h CUSTOMIS JKRTD 8000 kg/h CUSTOMIS How it Works Hot air is generated by wood/ Briquettes. Material is conveyed by screw at feeding point. Material is spreaded by lifters in horizontal shell. Hot air is sucked by fan through shell in the presence of wet material. With the rotation of cylinder, the material flow down to the lower end with the effect of gravity and discharge after drying, at end point material comes out with the help of cyclone & Rotary valve with required moisture. Evaporated moisture goes in atmosphere by sucking fan. Various models of Rotary Dryer are available basis on Moisture content and production requirements. Complete System of Rotary Dryer is automated where moisture content is adjustable. After the damp raw material is put into the dryer from one end, it is turned over through string-up rake inside the cylinder and distributed uniform in the dryer and contacted with counter current hot air fully. It speeds up heat and mass conducting of dry. During the period of dry raw material is effected by stirring-up rake with gradient and hot air. It can be moved and passed through the dry region and to star valve and then discharge the finished product. During the Drying Process, the best moisture content to pellet and briquette is about 13-15% and 11-12%, the function of the Rotary Dryer is to make the crushed pieces with suitable moisture. -

According to the requirement of the market, Zhengzhou Dingli New Energy Technology Co., Ltd designs and manufactures paddle rotary dryer, which is as known as the paddle-harrow rotary dryer. It is specifically designed according to the problems of traditional rotary dryer. which is not suitable for high-moisture materials that MC is higher than 50%, and the viscosity is relatively low. Meanwhile since the black hole phenomenon occurring in the drum lowers the drying capacity and raises the energy consumption. The paddle rotary dryer sets high-speed spinning paddles, strengthening the crushing, and separating function. The crushing effect enlarges the contact surface of particles, which largely increases the heat transfer rate and vaporization rate. According to the practical test, the unit vaporization capacity per hour of paddle rotary dryer is as much as 25-60kg/m2, which is 1-2 times of traditional rotary dryer. The output is raised by 50% and fuel consumption is reduced by 30%. At the same time, the footprint and drying efficiency is raised by 40%. It is applicable for the drying process of high-moisture materials with 50%-85% moisture, such as sludge, bean dregs, starch residue, and sauce residue, spray corn bran, cassava dregs, brewer's grains, distiller's grains, straw, grass, organic fertilizer, chicken beef feces. We also help optimize the drying process according to the property of different biomass materials, production scale, application requirements, cost control, automation level, and site condition.
