Coal Dryer - Hongxing Mining Machinery

Product Introduction

The coal dryer is a rotary drum dryer. It is a very mature drying equipment. It is suitable for drying coal slime, clean coal, and coal. Lignite, clean coal, sludge, magnetic, heavy, and float concentrates of metal and non-metallic minerals, and clay in the cement industry. It is characterized by high productivity and easy operation. The coal is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe through the feeding machine of the hopper. The material is added from the higher end, and the heating medium enters from the lower end, and is in countercurrent contact with the material. When the wet material moves forward in the cylinder, it directly or indirectly receives heat from the heating medium, so that the wet material can be dried, and then sent out through a belt or screw conveyor at the discharge end.

Features

High thermal efficiency : The thermal efficiency is 80% to 90%. The new internal structure strengthens heat conduction of dispersed materials, and eliminates the sticking phenomenon of the inner wall of the cylinder.
Stable drying quality : Since the heating mode is easy to control, the temperature inside the cylinder and the heat transfer rate of the partition wall can be kept relatively stable.
Long parts life, not easy to wear : The cylinder of the dryer is made of steel material, which has the characteristics of high hardness and high toughness.
Simple operation, environmental protection and energy saving : The dryer system has good sealing performance, and is equipped with a complete dust removal device, with little dust spillage and a good operating environment.
