MASS MIXER

MASS Mixer has been well-designed to facilitate thorough mixing of dry or damp materials and is especially suitable for tablet granulation. The powerful geared drive and sturdy mixing paddle make MASS Mixer ideal for dealing with difficult or sticky ingredients. This is one speed Mixer but two speed machine available on demand.
In operation, material is loaded through the top inlet.

OPERATION

The working volume (volume up to which material should be loaded) of the Mass mixer ranges from 30% to 70% of the total drum volume. The shaft rotates at higher speed, producing a plough tip speed of more than 200 metres per minute to effect a fluidizing action. The Mixer throw the material upward, and the material settles in a random pattern. The size, shape, positioning, and peripheral speed of the ploughs are coordinated in such a way that they produce a whirling, three-dimensional product movement. The turbulence and material movement within the mixer container prevents formation of dead-spots or low-movement zones and ensures fast and homogenous mixing. The Mixer are designed to lift the material from the inside wall of the container without squashing the particles against the wall.

CONSTRUCTION

The Mixer consists of Mixing drum complete in itself. It contains mixing drum body. Mixing paddle and sealing arrangement. The drum rests on rigid M.S. fabricated body carrying Motor, Gear box, Starter and tilting arrangement. The drive of mixing paddle is through suitable oil filled worm gear unit which in turn get drive through V belts from a suitable T.E.F.C. motor. The blades of the paddle are so arranged that thorough mixing is obtained. All parts which are in direct contact with the material to be mixed are of S.S. or neutral material. The main paddle runs in journals and supported by thrust bearings of ample size to carry rigid and thrust load. The whole drum of mixer makes ease of cleaning. The rotor is so designed that it can be removed , by removing the main shaft without much problem.

PLASTIC DUST COVER

The material under mixing process can be apparently seen from the Plastic Dust Cover of the container at all times and it, being hinged and holding allows solution to be added through without difficulty while the mixer is in motion.

SAFETY

The plastic dust cover is so interlocked that on opening the cover the motor automatically stops. The interlocking system is given to avoid the accident as the machine will not start unless and until container is totally closed. This is of utmost importance in a machine like this which has revolving blades.

TILTING DEVICE

The Tilting Device is provided to ease the unloading of the material. Tilting is affected by means of a hand wheel on the body, the powder or granules being tipped into a container which can be placed at ease.

SEALING ARRANGEMENT

Specially designed self-adjusting sealing arrangement of unique design is provided to ensure that no black particle enters into the Mixing drum. However, little powder from inside may come out sometime after a long use which suggests cleaning and readjusting of pressure springs.

LUBRICATION

Provision is made for lubricating all moving parts and specially designed to prevent oil coming in contact with the powder.

APPLICATIONS OF MASS MIXER

  • Chemicals
  • Pharmaceuticals
  • Ceramics
  • Agrochemicals
  • Veterinary
  • Adhesives
  • Brake linings
  • Confectionery products
  • Detergents
  • Waste treatment

Mass mixers are available in batch modes and for continuous operations. The batch Mass mixer is the most versatile mixer type available with an extensive range of applications:

  • Dry powder mixing – e.g. Food flavoring/additives, Sponge/cake mixes, Cosmetics, Pharmaceuticals, Cement, Powdered rubber
  • Paste mixing – e.g. Biscuit creams, dough, PVC pastes, Car body fillers/putties, Sugar/marzipan paste, Toiletry pastes, Tile adhesives and grouts
  • Mixing of wet slurries – e.g. Filter cake re-slurrying, dough, Fiber glass resin dough putty
  • Wet granulation
  • Liquid coating of powders and granules
  • Fat and oil incorporation
  • Vacuum drying
  • Hot air drying

Continuous Mass mixers differ from batch ploughshare mixers in that the mass flow of the product is from the inlet of the container to the discharge at the opposite end. Typical applications of continuous ploughshare mixers are:

  • Detergents
  • Dry cement blends
  • Sludge conditioning
  • Wetting out industrial dusts
  • Coal reclamation
  • Blending of minerals
  • Granulation
