Rotary Dryers / Coolers are widely used in the Industry for drying / cooling of reasonably free flowing materials.
AVM offers Customized Rotary Drying Systems with variety of Configurations. ![]()
The material to be dried / cooled comes in direct contact with the drying / cooling media.
The rotary dryers compris of a rotating shell supported on rollers / tyres and driven by means of suitable drive arrangement. Drying / Cooling media ( Air / Gas ) is admitted through stationary hood at one end & taken out from stationary hood from other end. Feed is admitted through suitable feeding mechanism like Screw feeder / Chute. The rotating shell in these rotary drying systems is provided with specially designed material showering mechanism like Lifters / Garland Chains etc. Shell inclination & rotating speed facilitate forward movement of the material towards discharge end providing required residence time. Drying ( or Cooling ) takes place by heat transfer to ( or from ) showering material with the drying ( or Cooling ) media within the shell. Rotary drying systems are discharged from the stationary hood through suitable equipment like Flap Valve / Rotary Valve / Screw Conveyor / Chute. Air Flow Configurations:

In-Direct Rotary Dryers: The material to be dried does not come in direct contact with the drying media. The rotary dryers comprise of an assembly of two concentric rotating shell supported on rollers / tyres and driven by means of suitable drive arrangement. Feed is admitted through suitable feeding mechanism like Screw feeder / Flap Valve into the dryer through stationary feed hood. The drying media is admitted through the inner shell & travel towards discharge end & again returns towards feed end through specially designed return gas passages on the inside of outer shell. The inner shell is also provided with suitable radial lifters. These lifters alongwith return passages geometry is designed for showering of feed material. Shell inclination & rotating speed facilitate forward movement of the material towards discharge end providing required residence time. Drying takes place by heat transfer to the showering material by direct contact with inner shell & return passages. Product is discharged from the stationary hood through suitable equipment.

Rotary calciners are used for calcining of the material at high temperature.
The Rotary Calciner comprises of rotating shell supported on rollers / tyres and driven by means of suitable drive arrangement The internals are suitably refractory lined to minimize the heat losses. The combustion chamber is used for producing hot gases required for the calcination and it is connected to the Rotary Calciner through a stationary hood. The feed material is fed into the calciner feed hood through Screw Conveyor at controlled rate. The material to be calcined travel in counter current fashion within the Calciner and gets discharge through discharge hood. Air Heating System Configurations:

AVM produces a variety of industrial conduction
dryers like tube bundle dryers, rotatory speed dryers, rotor type dryers
that are used for different types of products and can be customized as
per customer needs.
Tube Bundle Dryers:In this dryer, tube bundle is rotating inside stationary housing.
Heating Media is passed through the tubes of Tube Bundle. Material to be dried is fed into the stationary dryer housing at suitable location at one end. The material gets lifted up & showered on tubes with help of specially designed lifters provided on tube bundle periphery. Material gets dried by conduction heat transfer & discharged from the other end. ![]() AVM offers customized configurations of Tube Bundle Dryers.
Rotary Steam Tube Dryers:![]() In this dryer, tubes are fixed to the outer shell housing & rotate along with the shell.
Single / Multiple rows of tubes are circumferentially arranged on the internal periphery of the rotary shell. Rotary shell is supported on tyres / rollers & driven through suitable drive arrangement . Wet feed material is fed through center of one end of the Dryer by feed screw. Steam is admitted in the circumferential tubes from a rotating manifold installed towards material discharge end of the shell through Rotary Joint. Condensate is also collected through the same Rotary Joint. Material gets dried by conduction heat transfer & discharged from the openings provided on the shell at the other end. The openings also serve for fresh air intake. Vapours are removed from the feed end. spiral flight lifters showered the feed material on tubes. AVM offers customized configurations of Rotary Steam Tube Dryers.
Agitated Rotor Type Dryer / Heater / Cooler![]()
AVM offers customized configurations of Agitated Rotor Dryers.
When used as Dryer / Heater, heat is supplied to jacket of stationary cylindrical housing. The material to be dried is kept in agitation by means of specially designed rotor. Rotor is specifically configured depending on material characteristics & can be Screw / Ribbon / Paddle / Plough / Anchor / Special Type etc. Heating Media can be Steam / Hot Oil / Hot Water / Thermic Fluid etc. Solvent Recovery option is also possible. For using as Cooler, suitable Cooling Media can be circulated in the jacket. |
Vacuum Dryers are widely used in the Industry for drying of variety of products.
Vacuum Dryers are batch dryers ideal for drying of heat sensitive products, drying of products in solvents ( for subsequent solvent recovery ), drying requirements necessitating achievement of very low moisture or low oxygen drying environment to minimize oxidation or for explosion prone products. AVM offers Customized Vacuum Drying Systems with variety of Configurations. Agitated Cylindrical Vacuum DryerIn these dryers, heat is supplied to jacket of
stationary cylindrical housing. The material to be dried is kept in
agitation by means of specially designed rotor.
![]() Features Configurations:
Double Cone Vacuum Dryer:![]() In these dryers, heat is supplied to double conical shaped rotating jacket. The material to be dried is kept in continuous tumbling within the rotating housing. Conical shape facilitates easy drain out of material at the end of the batch.

Rotary Atomizers are used in Spray Drying for
atomizing the feed into fine droplets. In Rotary Atomizers, the kinetic
energy of wheel rotation is used for atomization of the liquid.
Droplet size of atomized liquid depends upon liquid properties, disc speed, disc configuration etc. Bulk density is also one of the critical product requirement of spray dried products. The desired results can be achieved by using different Atomizer wheel configurations and optimizing atomizer speed, optimizing relevant feed properties. ![]() AVM offers following models of Rotary Atomizers.
Wheel Configurations: Standard wheel with radial openings, Pin wheel, Curved Vane Wheel, Slotted wheel, Non String Forming Wheel, Umbrella type Wheel etc. Lubrication System Options : Gravitational Wick Lubrication. / Forced Lubrication Optional Features: Speed Indication, Vibration Monitoring, Steam sparging. |
