Multi Mill

Multi mill is a self contained portable unit useful for high speed Granulating, Pulverizing, Mixing, Shredding and Chopping of aMulti Millwide range of wet and dry materials without special attachments.

  • Multi Mill operates on the principle of variable force swing, beaters having both knife and impact edges rotating within a selected screen to get the required size reduction.
  • Multi mill is designed to utilize the principle of variable force swing beaters having both knife and impact edges rotating within a selected screen to control the particle reduction, material fed in to the processing chamber moves to the periphery and passes through the screen radially and tangentially.
  • Finally the processed material gets collected into the container kept below the processing chamber.
  • As compared to the four common principal of size reduction i.e. grinding, compression impact and shearing, which often do not produce controlled size reduction, this machine utilizes the principle of variable force swing hammer blades having both knife and impact edges rotating with a carefully selected screen to control size reduction.


  • Machine rated for continuous operation
  • Higher output with process uniformity.
  • All contact parts of SS 304 AISI (SS316 quality is optional).
  • All contact parts can easily be dismantled and cleaned for change of product.
  • Wide range of SS perforated or wire knifted screens available.
  • Machine portable on castor wheels.
  • Direction of blade rotation reversible.
  • Different size of screen / speed/number of blade / direction of rotation of blade can be selectedUnique 3600 screen for higher out put.
  • Additional perforated screen at the bottom of pulverising chamber to eliminate higher percentage of fineness and control granule size more effectively and obtain higher outputs.No expensive dust collection system required when used for pulverising.

Fluid Bed Dryer

The fluid Bed Dryer are most suitable for drying granular crystalline, coarse or similar material in pharmaceuticals, fine chemicals, dyes, food and allied products. The fluid Bed dryer is not suitable for drying liquid or pasty materials.

  • Fluid bed dryer is designed to introduce the hot air stream at the base of the product container which is filled with theFluid Bed Dryer material.
  • Induced draught is created by means of blower and fresh air is sucked in to the unit. This hot air system expands the bed of material at certain velocity & creating turbulence in the product. The phenomenon is known as fluidization and offer conditions which are almost ideal for drying.
  • Fluidization produces full agitation of solid particles and since each particle gets surrounded by hot air, heat transfer is extremely high and uniform.
  • The product is dried fast without appreciable loss of heat. Filter bags prevent particles escaping from the dryer.
  • Fluid Bed Dryer occupy lesser floor space compare to conventional dryer and are very easy to operate and can dry material in least time as compared to tray dryer.
  • In fluid Bed Dryer, temperature distribution through out the product is uniform and the heat transfer rate is very high. High production rates are achieved due to reduce drying time.
  • As the product is in close contact with drying air at low temperature and also for short duration, the physical and chemical properties of the products are generally not effected and therefore the dryer can effectively be used for heat sensitive products.
  • Due to the continuous movements of product during drying lump formation, case hardening etc. are minimized.

Tray Dryer

A tray Dryer is an enclosed insulated chamber in which trays are placed on top of each other in trolleys. Tray Dryer are used where heating and drying are essential parts of manufacturing process in industries such as Chemicals, Dye stuff, Pharmaceutical, Food Products, Colours etc. The material to be dried either wet or solids are placed in the trays. Heat transfer is by circulation of hot air by electric heaters or steam in radiator coils. Blower fans are installed inside to ensure proper circulation and transfer of heat. A control panel to control the temperature and other parameteres is fixed outside the dryer. These dryers are available in Mild Steel, Stainless Steel or construction. Tray dryer is used for drying of pigments, food, bakery, electrodes, chemical and plastic powders.


The Drying ovens are normally available with choice of heating mode, as electrically heated / steam heated & thermic fluid heated..

In electrically heated model, digital temperature controller provided with digital timer to facilitate working day and night. In steam & thermic fluid heated model, digital temperature indicator is provided with digital timer , but the temperature controller is not supplied with the machine.


A highly effective recirculating air system is provided. The heated air, is recirculated with fresh air in selected proportions for optimum drying. The system is designed so that the materials at the top & the bottom dry simultaneously.

Uniform air circulation, controlled temperature, sturdy construction and large working space are the valuables of the oven which is suitably designed to cover wide temperature range, loading and unloading is faster and simple. In higher capacities trays trolley rolls in and out of the chamber. For continuous operation a spare trolley can be had for loading while the drying cycle is taking place.


Digital temperature controller with digital timer are supplied to facilitate working day and night.
