What are the classification of the drum dryer? According to the drying medium and wet material between the heat transfer method is divided into direct heat transfer drum dryer (drying medium and wet material direct contact heat transfer) and indirect heat transfer drum dryer (the heat required for drying from the cylinder wall Indirect transfer to the wet material) two. Indirect heat transfer drum dryer low efficiency and complex structure and other reasons, rarely used, do not do this.
Direct heat transfer drum dryer, in accordance with the drying medium and material flow direction, is divided into two kinds of downstream and countercurrent.
Suitable for after replacement market SMOOTH OPERATION: Stable and smooth operation, good mute effect, practical and durable. The bearing is stable, low noise and long service life. STAINLESS BEARING STEEL MATERIAL: It is made of high quality stainless bearing steel material, rust and corrosion resistant. Product hardness, high precision, can withstand high speed, high load. HIGH PRECISION & HIGH HARDNESS: High precision, high hardness, high speed, high load, applicable for motors, toys, models, instrumentation, power tools, communication equipment, fitness equipment and other fields.
