In the processing links such as mineral smelting and roasting, the control of moisture is very important. The large-scale concentrate powder pellet dryer equipment developed by the dryer manufacturer Zhengzhou Jiutian Machinery is a large processing capacity, stable and efficient, and a high degree of automation. The special dryer, the internal structure of the equipment is made of high-strength wear-resistant materials, the equipment has a long service life, and the diameter can reach more than 4 meters. It is suitable for iron concentrate, manganese ore powder, cobalt ore powder, copper concentrate, gold ore powder, lead Rapid water control and humidity control of concentrate pellets such as fine powder, tin ore powder, mercury ore powder, phosphorus concentrate, molybdenum concentrate, etc.

The concentrate dryer system adopts a horizontal rotary drum structure, and a special design is made on the internal structure of the drum, which further strengthens the contact area and heat exchange time between the material and the drying medium, improves the thermal efficiency, and helps to reduce the drying cost . The principle is as follows: the concentrated mineral material with moisture is fed from the nozzle, enters the cylinder evenly, and is scattered by the lifting device to form a uniform end fabric curtain layer, which is mixed and exchanged with the entering high-temperature gas. Due to the rotation and inclination of the cylinder, The material turns over in the circumferential direction and moves in the axial direction. The material is continuously lifted and scattered by the lifting plate. The material and the gas exchange heat while moving in the cylinder at the same time, so that the moisture of the material is continuously evaporated and gradually dried. The temperature drops gradually, and the dried material is discharged from the lower end.
