Techno Designs offers Ball Mills in various styles such as Batch, Continues, 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.

Continuous Mills are offeredin1)EndPeripheralDischargetype2)TrunionDischargetypeand3)AirSwepttype.
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.

TECHNO Bead Mills are capable of producing finely dispersed finished product from directly charged raw materials.

Three operations of premixing, grinding and dispersing are combined within one machine. The machine operates on the principle of shear created within the mass differential of product and grinding media. The grinding medium is moved to the vessel wall by the action of the specially designed disc impeller. This constantly moving mass of grinding media is force-flowed up the side of the vertical vessel wall, the action continuing until the vortex spiral directs the media movement towards the agitator shaft for another continuous cycle of events.

The main grinding shell is jacketed for cooling. This is a very speedy operation wherein major products are achieved to the respective gauges in about 1-1/2 hours time.

The applications are Synthetic enamels, Water based primers, Red oxide primers, Artist colours, Flexography inks, Industrial finishes.

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 Bead 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 beads by means of discs fixed on the agitator. The grinding beads transfers the energy to the material and high shear and high peripheral velocities reduces the particle size of the material to be ground.

CONTINUOUS

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 beads are separated from the material by means of gap separator or by Wedge Screen.

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 designed 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 designed 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)
