Where To Use :
Techno Designs offers Ball Mills in various styles such as batch, continuous, jacketed and non jacketed for powder grinding and wet grinding of various materials as varied as minerals to pigments. The Ball Mills are versatile grinding equipments and are used by pigments, paints, minerals industries.

Techno Designs has specialized in manufacturing of continuous ball mills for various applications. The unique feature of the mill is its assembly. The shaft run outs for mills of 20000 ltrs capacity is less than 200 microns. The support bases are from fabricated plate sections and the top plate where the bearings rest are planed to give a perfect seating.

Jacketed mills are offered for cooling as well as for heating applications also. Techno Designs has already manufactured mills with gross volumetric capacity of 25000 ltrs with drive motor OF 425 H.P.

Where To Use :
Techno Designs offers horizontal as well as vertical sand mills for wet grinding of various kinds of materials such as pigments, agrochemicals, dyes, paints, minerals and various other type chemicals etc. This is primarily used for size reduction of the materials. This Sand Mills are used for continuous dispersion and fine wet grinding for high to low viscosity pumpable fluids.

Principle :
The necessary energy for grinding is given by rotating the Sands by means of discs fixed on the agitator. The grinding Sands transfers the energy to the material and high shear and high peripheral velocities reduces the particle size of the material to be ground

Construction :
It consists of a Horizontal/Vertical Cylindrical jacketed shell with a central shaft on which number of discs is fixed. The shell is provided with cooling jacket. The shaft end is sealed by double mechanical seal The feed pump and the electric panel is mounted on the main machine with all necessary required instrumentation and controls. The grinding Sands are separated from the material by means of gap separator or by wedge screen.

Where To Use :
Techno Designs offers RVD for clean, simple and effective way of drying of wet cakes, wet powders, slurries where either solvent is to be recovered or drying is to be carried out at relatively low temperature for heat sensitive material.

Construction :
It contains a hollow shaft with specially designsed hollow arms, which are heated by steam / hot water / thermic fluid; rotating in a centrally jacketed shell. The entire shell area is effectively covered by the specially designsed scrapper arms, which scrape the entire internal surface of the dryer and continuously move and rotate the material remaining in contact with hot surfaces for protracted periods of time. This reduces the drying time.

Operation :
After starting agitation, feed is charged and vacuum is applied in RVD, dust catcher, condenser and receiver. Then heating the mass causes vapor to evaporate, which is subsequently condensed and collected in receiver. The recovery of solvent is maximum and drying time is low because of higher heat transfer, vacuum and intensive mixing.

Salient Features :
As each material is unique in nature, Techno Designs offers pilot trial for understanding drying behaviour and predicting data on power and heat input along with drying time. Optional features like breaker bar (for minimizing lump formation for particle size reduction), nitrogen purging (for explosion proof environment), stationary scrapper blades (for scrapping rotating agitator for highly sticky material), sampling valve (for collecting samples during vacuum application), flame proof motors (for Ex-proof environment).

Where to use :
Plough Blender / Reactor can be used for Solid, liquid, blending and reacting various kinds of industrial reactions.

Construction :
It contains specially fabricated plough arms fixed on a rotating shaft with a stationary shell. The shell is jacketed or limpeted and can be heated or cooled by steam, thermic fluid and hot water. The cooling can be by water, chilled water and brine solution. This is fixed with high shear choppers which enhances blending and also reduces particle size.

Salient Features :
Techno Designs offers Plough Shear Blender/Mixer/Dryer for different blending/mixing and drying; for high efficiency and reduced process time at a relatively low power requirement. These machines are highly reliable for obtaining perfectly homogeneous blends for dry, fine as well as coarse powders, grains and pastes; depending on material characteristics. It is used for materials having poor flowability or sticky in nature or where shorter time is required for blending. These blenders are equipped with mixing elements; which can be adapted to individual requirement. Thus the blending produces are one of the highest quality. The shovels rotate as mixing elements in a special arrangement on the shaft in a horizontal cylindrical drum. The size, number and positioning, geometric shape and peripheral speed of the mixing elements are coordinated in such a way that they produce a three dimensional movement. This three-dimensional movement eliminates the possibilities of damaging the structure of particles to be blended. The three-dimensional movement also prevents formations of dead spots or low movement zones.

The agitator configuration depends on material density, flowability, blending time, abrasiveness etc.

Specification -:-
Dissolvers offered by Techno Designs are sturdy & rugged in construction. The blade offered is generally saw tooth cutting. The high-speed impeller mill consists of high-speed shaft, serrated impeller and mill container. Dispersion is effected by the attrition of pigment agglomerates under the viscous forces induce in the paste by the high-speed impeller. The machine can be lowered or lifted by hydraulic or pneumatic arrangements. The motors available are TEFC or explosion proof. The speed variator can be mechanical or electronic invertor.
