Rotary kiln dryer

  • Product Name: Rotary Kiln Dryer
  • Product model: HZG
Product details:

Overview Rotary kiln dryer is used for pre-firing of hard ferrite powder. It can also be used in cement, metallurgy and chemical industries. The equipment consists of the main kiln and its supporting transmission, cooling pipes, fuel system, electrical control, secondary air inlet device, exhaust dust removal device and preheating kiln body. With over temperature alarm, overload alarm, automatic control of working temperature, adjustable oxygen in the kiln and other functions.

Principle After the wet material is put in from one end of the dryer, the material is evenly distributed and dispersed in the dryer when the plate reader is uniformly distributed in the inner cylinder, and it is in full contact with the cocurrent (countercurrent) hot air, which accelerates the drying heat transfer. Driving force of mass transfer. During the drying process, the material can be controlled to move to the star-shaped discharge valve of the other section of the dryer to discharge the finished product under the action of the inclined plate and hot air flow.

Application Suitable for drying large particles and specific materials in chemical, mining, metallurgy and other industries.
Such as: ore, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.
Drying of powdery and granular materials with special requirements. Such as: foaming agent, lees residue, light calcium carbonate, activated clay, magnetic powder, graphite, medicine residue.

Features require low-temperature drying and large batches of continuously dried materials.
The drum dryer has a high degree of mechanization and a large production capacity.
The fluid passes through the barrel with low resistance and low function consumption.
Adaptability to material characteristics is relatively strong.
The operation is stable, the operation cost is low, and the uniformity of product drying is good.
