Rotor dryer

Product Detail

Rotor dryer is used in particleboard production line.The main function is to eliminate the moisture in the shavings, so that the moisture content of the shavings can meet the technological requirements.The dryer with heat conduction oil as medium has high thermal efficiency, stable temperature, low pressure operation, energy saving and consumption reduction, safety and reliability.

Rotor dryer consists of shell, rotor, steam joint transmission device, preheater and other main parts.The center of the tube bundle is composed of a certain number of heat pipes. After the wet material enters the person from the feed port, it contacts with the tube bundle. The wet material is heated and dried by effective heat conduction, radiation and convection.Rotor consists of the main shaft, on the main shaft bearing channel steel and welding material shovel, etc, on bearing bad steel tube tie, one end is fixed connection, on the other side is floating connection, each bundle disassembly, separately used outside fixed bearing, spherical roller bearing spindle end outside the other end with free bearing, spherical roller bearing to eliminate heat bilges cold shrink deformation stress.The transmission part drives the rotation of the rotor, and the rotor speed can be stepless adjusted in the range of 4~12 RPM.Steam enters each tube bundle from the inlet of steam joint and flows in the tube to heat wet material. After heat exchange, steam is discharged from the outlet of steam joint.The fresh air heated by the preheater is sprayed into the left shaft body of the rotor, and enters the dryer through many holes on the hollow left shaft body. Its role is to strengthen air convection, but also affect the residence time of materials in the machine, and the wet air in the machine is discharged from the wet outlet.Feed shovel, shovel, discharge shovel constantly moving, rolling material in the machine and forward transportation, because the material constantly falling from the feed port, and contact with the heat pipe, get effective heating, dry after discharge from the discharge port.Features: the equipment has simple structure, less wearing parts, safe use, its bundle can be disassembled, convenient maintenance, suitable for drying various loose materials such as wood shavings, bagasse, beans, peanuts, etc., with high thermal efficiency, up to about 80%.Its hot medium can be steam, hot water, hot oil.Application: Building materials: shavings, etc.
