High Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying
1. Brief introduction of rotary dryer :
cement Rotary dryer is widely used for drying slag limestone, coal powder, slag, clay, etc. Dryer can also be used in building materials, metallurgy, chemical and cement industry. Rotary Dryer mainly consists of dryer body, raw material feeding plate, driving and supporting device, seal ring, etc. Dryer can be generally divided into four types, they are: rotary dryer, triple-drum dryer, indirect heat transfer dryer, vertical dryer. Different kind of dryer has its own characters and advantages, the specific choice of a special dryer depends on different elements.
2. Rotary dryer Working Principle:
1. Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator.
2. Materials enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, and then materials and hot air mix together.
3. Materials go to the lower side by gravity when the barrel is rotating.
4. Lifters on the inner side of barrel lift materials up and down in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of rotary dryer.
Cement Rotary dryer internal structure of the lifting plate type :
In order to increase the material evenly distributed on the cross section of the cross section and the drying medium has good contact, in the cylinder body install lifting plate,. There are several kinds of lifting plate for the rotary dryer:
1. Lifting type Lifting plate: suitable for large lump material or easy to be bond in the wall of the material.
2.Four grid type lifting plate: applicable to large density, not brittle or not easily dispersed material. The lifting plate will divide the inside cylinder into four grid, will form a fan operation room not communicating with each other, the contact area of the material and the hot air is larger than the lifting type,and it can increase the material filling rate and reduce material falling height and reducing the amount of dust loss.
3. cross shape or frame shape plate: suitable for more brittle and easily dispersed small pieces of material, so that the material can be evenly distributed in the entire section of the cylinder.
4. sleeve type lifting plate: for multiple heat transfer (or semi diameter heating) rotary drum dryer.
5. cellular type (fan) plate is suitable for fine particles and easy to cause the powder fly. When material feeding is piled up in the lattice board, when the cylinder rotates, the material is stirred and constantly in contact with hot air, at the same time for the material landing height decreases, reducing the possibility of drying materials taken by hot air.
In various forms of lifting plate above can be distributed throughout the whole rotary dryer cylinder, in order to cause the material to quickly and evenly to the lifting plate,can install screw guide material plate at the feed end of 1~5m, in order to avoid the accumulation of wet material bonding on the cylinder wall. At the same time because of dry material is very easy to be raised and was taken away by the waste gas, and in the discharge end of the 1~2m is not installed any lifting plate.

4. Cement Rotary Dryer Features:
1. Our cement rotary dryer adopts new Spreading plate device, which has guidance, flow, material functions
2. It can make the material content in the dryer radial cross section to full uniform, material will become thin and all.
3. The state of the heat flow entirely, to achieve the purpose of make full use of the heat.
4. Our dryer choose reasonable operating parameters, coal consumption and power consumption of general baked dry machine more than 10-15%, one machine yields above 10-15%.
5. It has been widely used in the cement and mineral processing enterprise.

Jinan Joysun Machinery Co., Ltd. for thawing of meat products and seafood, the equipment has stable performance, reliable quality and short thawing time. It is an ideal defrosting equipment for high-tech meat products, made of stainless steel, conforming to food production standard. Welcome new and old customers to inquire. Our international business covers customers all over the world. We have competitive prices and are proud of our excellent after-sales service. The working attitude of the company and the continuous improvement of the innovation concept will lead Tuo Bo and you to step into the brilliant future hand in hand and create a better future.
Through continuous exploration and practice, the company has developed the advantages of low investment, high efficiency, low operation cost, high product quality and convenient control and operation. The microwave frequency thawing equipment with microwave frequency of 915MHz and output power of 20kw-200kw is above. For food processing enterprises such as chain fast food industry in China, food thawing is provided, and the improvement of food thawing technology in China is also renewed. The benefit is not only "farsightedness", but also at the foot of the eyes. According to experts, the traditional food thawing are based on heat conduction method, material surface temperature is higher than the internal temperature in the thawing process, inevitably there will be drop loss, which will increase the business loss. If merchants use microwave dryer, High microwave Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying power, material temperature and transmission speed can be used to achieve adjustable linkage, and the overall heating process control advantages can greatly reduce material consumption and improve food utilization. In addition, as the microwave thawing only needs electricity, no need to consume a lot of water, in the low carbon era, this is not lost a recommended fashion trend.
microwave dryer is a new type of environmental protection drying method. When dry, High microwave Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying directly to the medium molecules converted into heat, because the High microwave Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying penetrating performance of heating medium and at the same time, no need to heat conduction, so the heating speed is very fast, the water content below 30% of the food, the drying speed can be shortened hundreds of times.
microwave dryer advantages of equipment
1, microwave dryer, short, fast
Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The High microwave Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.
2, High microwave Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying low temperature sterilization keep the nutrition and traditional flavor The High microwave Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.
3 microwave dryer and High microwave Efficiency Cement Plant Cement Dryer For Cement Raw Material Drying save energy Conventional thermal sterilization often has heat loss in the environment and equipment, and microwave is directly treated to food, so there is no extra heat loss. In addition, the conversion efficiency of the electric energy to the microwave energy is in the 70-80%, and the power is generally reduced to 30-50%.
