We are hunting for new practical efficient dryer

Industrial dryer has become more popular along with the growing needs of heavy industry. The drum dryer is one of the traditional industrial drying equipments, according to the usage, they can be classified into slurry dryer, coal dryer, shape-coal drying equipment. Because the equipment is relatively large, it is also known as large-scale dryer.

Industrial dryer features: dryer processing capacity is large, less fuel consumption, low-cost drying. The dryer has high temperature characteristics, and is able to use the high-temperature hot air to dry materials rapidly. Dryer is scalability, the design allows for the production margin, even if small output with a small increase, it doesn't need to be replaced. Equipment adopts special designed structure, and the tugs and rolling circle matched perfectly, so that it greatly reduces wear and power consumption. It is anti-overload, and tube body is able to be in smooth operation with high reliability.

Energy-saving measures for new dryer: (1) Transform the dryer tail at low temperature drying at about 1/3 of the L-shaped lifting plate. Generally, L-shaped lifting plate is vertical fixed in 90 °, and the plates around can be welded in 30 °, 90 °, 120 ° angle respectively; Thus, the spreading area enlarges by industrial dryer rotating. Consequently, the heat exchange rate is higher; Be noted that the transformation of the industrial dryer should consider comprehensively. If the ventilation is good, the exhaust gas temperature is over 100 ° C, we can add a few X-shaped center sets. On the contrary, if poor ventilation, the exhaust gas temperature is below 70 ° C, we need to reduce groups of the X-shaped lifting plate center; It is very important to control exhaust gas temperature. When temperature is too high, on the one hand, it will cause high energy consumption, on the other hand it will burn the dust bag; The other way around, it will cause a bag paste, which affects ventilation, and makes production decline, severe dust internal component corrosion and high maintenance costs. 

2. Drying material flow speed is too fast to control, we may add a few sets of X-shaped center lifting plate, but we must take into account the ventilation and exhaust gas temperature; If the conditions are not allowed, the retention ring set and location should depend on the circumstances. However, the disadvantage is that the front part of retention ring of the cylinder is easy wear, in that case, we can choose wear-resistant material or thickening in this region of the plate. 

Large industrial dryer is a very important process flow in the ore dressing production line. The dryer production line operates reliable, flexible, and adaptability with large processing capacity. It is widely used in the field of metallurgy, building materials, chemicals, coal washing, fertilizer, ore, sand, clay, kaolin, etc.
