General Knowledge of the Rotary Dryer

What is rotary dryer ?
Let me tell you now, it is a kind of  drying device. The materials in the drying rotating cylinder coaxial  columns sets are dried by the lifting process of spiral blade and intermittent spiral lifting plate exhumation between the inner and outer cylinder   .

The work principle of the rotary dryer:
Rotary dryer adopts the sleeve sets column structure to doubled   shorten the length of the dryer,duo to the radiating surface is significantly reduced, resulting in heat consumption decreased,  so the thermal efficiency is greatly improved by the double increase of the heat exchange surface. As to the materials which can not touch the tobacco materials, multi-drum rotary dryer provided the inner and outer cylinders respectively within the smoke pipe and the annular pipe, the energy-efficient is same. It is not difficult to see that this machine is the most ideal sleeve rotary cooler for the hot feed and cold media.

Rotary dryer features:

1. high degree of mechanization, large production capacity,   continuous operation.
2. Structure is excellent, simple, material running smooth through the barrel resistance, easy operation.
3. Less failure, low maintenance costs, low power consumption.
4 Wide application scale, good dry product uniformity.
 

Rotating the structure of the dryer
Rotary dryer can be designed based on the user needs, such as the gas furnace, combustion chamber or supporting hoist, belt conveyor, quantitative feeder, cyclone, induced draft fan.
The main parts of the cylinder are as follows: the front roller circle, rear roller rings, gears, gear roll; drag roller, pinion, discharging part, Yang plate, reducer, motor, hot air channel, feed chute, furnace part .

Installation and Commissioning of the dryer:

1, the installation of the dryer should be strictly carried out according to the requirements on the assembly drawing and foundation drawing  , before the installation of the dryer, we should clear all spare parts of the rotary dryer to gurantee the clean and completeness of equipment.
2, since the dryer is a long body large equipment, so the installation should be carried out according to this method:
cross the program baseline, made the right crosshairs on the basis of standard board , level the high line, the center baseline should achieve the standard , including the consideration of not being covered.
 installed the base and the tugboat
Level the horn location, draw the center line of the base, tugboat, in accordance with the requirements of the drawings, identify the location of the installation of the base with the tugboat tone flat positive first foundation hole grouting, when the concrete reaches a certain intensity, tighten the anchor bolts. After the re-inspection,  install the cylinder.
