Rotary Dryer is continues drying process & are widely used for drying Minerals, Chemical and other solid Material Or Removing Damp (moisture) from Material. It is also used of heating (roasting) material .We offer our clients Rotary Dryer with fine and excellent grade, which is used in drying and heating of materials with excellent Results. And we design it according to requirement and usage of client (no fix Format like copy pest).

Use of Rotary Dryer in Various Industries:

  1. Minerals=Silica sand, Feldspar, Quartz, iron ore, chrome ore,
         i. Manganese ore, Zircon, steatite, Coal, etc.
  2. Ceramics industries = All Raw material of ceramic.
  3. Chemical industries = Bleach, PIGMENT and other solid form chemical
  4. Food industry
  5. Agro industry
  6. Fertilizer
  7. Pesticides industries
  8. Construction industry
  9. Other industry =Saw dust, wood chips , carbon, etc

Rotary Dryer Technical info

It mainly classified 4 types

  1. Direct (air heating method)
  2. Indirect (air heating method),

Rotary dryer heating source use like

  1. Hot air boiler = Direct
  2. Hot air boiler = Indirect fire
  3. Direct Flame fire = Oil (diesel/LDO/FURNESH) burner, gas burner, pellet burner, etc.

1) Direct fire = In direct hot air generator we get 100-750% Centigrade Hot Air

Direct fire rotary by oil fire, pellet Burner, coal burner in this dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counter flow.

2) In-Direct = In in-direct hot air generator we get 70-300% Centigrade Hot & Clean -Air for flow

The indirect is more useful for precious materials. In indirect dryer, there is little or no contact between the product and drying gases as they are heated from the outside the chamber through a stationary jacket fitted with either multiple burners or other external heat source.

3) Direct Fame Fire

It is used were high temperature is required with flame.

Rotary Working Process

The dryer is driven through a Gear Motor, girth gear and tire arrangement. seal are provided at Both ends to ensure minimum air and dust leakage. In this plant material is feed into rotary by feeder & hot air is generated in Hot-Air-Generator or Direct fire burner. By heat sours moisture will release from in-put material and we get dry material at output side Flow of Material and Heat can be adjustable according to party requirement means moisture and size of material. It my current flow or co-current flow it is design according to requirement of product to dry.

The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.

Construction of Rotary Dryer

Drier machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.

M.O.C = M.S, S.S (304/316) & M.S+S.S

Rotary Dryer is design according to requirement and usage of Consumer
