The Colloid Mill can be used as in line unit ( Horizontal execution) for the continuous operation in a process line, or with a funnel & circulation line ( Vertical execution).

The Colloid Mill has a broad application range & is used in the Food, Pharmaceutical, Chemical & Cosmetic Industries & even in water treatment plants. It operates successfully for products, which must be ground & well dispersed. It disintegrates particles faster & uniform swiveling without forming of agglomerates & for the homogenizing of products in one pass.

The Mill develops not only hydraulic high pressure in the grinding tool section. but turbulence & cavitations which, then combined provide both a gentle grinding & the required impact, squeezing, cutting etc. Effects for the homogenizing of products & wetting out of powders, all in one pass.

The centrifugal force of the rotor brings the material inside the mill. The rotor & stator combination with its exceptional large surface area provide both a gentle grinding & the required impact effect. A two way valve at the discharge connection of the Colloid Mill can either the processed material to inlet opening for rework or discharge the processed material. 

 

 

Safety Features:

The following additional features can be given with the machine at an extra cost if required.

Main impeller can be lifted by hydraulic cylinder by 100 mm during washing. Using this feature main impeller gets lifted up by a hydraulic cylinder by actuating an electric switch so that cleaning & visual inspection for validation process for the main impeller cleaning can be done easily. See drawing attached to understand this feature.

Main drive can be made to run on hydraulic motor so that main impeller RPM can be varied infinitely. With this & a tilting provision the high shear mixer can be used as a single pot processor where with mechanical seals vacuum drying of the wet mass can be done. Hydraulic tilting of entire bowl from 300o on either side with hot purging enables quicker drying. 

 

 

Working Cycle:

Dry Mixing -2 to 4 minutes

Wet Granulation - 4 to 15 minutes.

Discharge - 30 to 60 seconds

Complete Cycle - 6 to 20 minutes.

Raw material are charged as a batch & is subjected to indirect heating while undergoing rotary action. The conical shape of the dryer ensures efficient circulation of hot liquid heating media. The drying operation is being at low temperature under vacuum, that is why it is economical & effective for drying pharmaceuticals, temperature sensitive or easily oxidizable products. When the solvent is present in the wet powders, the recovery of solvent is easily possible. 

Drying take place when the dryer is heated from outside through jacket & vacuum is applied from inside. The drying operation is based on the principal that water or other volatile product moves from a zone of high vapour pressure to a zone of low pressure. This is accomplished by warming the product to be dried to raise the vapour pressure of the absorbed or free liquid, by decreasing the vapour pressure of the gas by vacuum, or by sweeping it away with an air current. Thus the essential conditions for effective drying are efficient & uniform heat transfer throughout the batch & rapid removal of the vapors.

The dryers are designed to meet customer's requirements flexibly & efficiently.

If required actual testing carried out works, for which, require quality of liquid would be arranged by the customer: otherwise testing can be carried out with water & insoluble carbon/ high flow.

 

The unfiltered liquid is fed into filter under positive pressure, where liquid travel in downward direction & finds its way through opening on side of the filter plates.

As the liquid pressure increase, the filter media holds the foreign particles & allows only clear filtrate to pass through the central channel formed by interlocking pressure cups to the outlet. Filtration is continued until rate becomes too slow due to cake resistance.

PLM is an ideal for the products fo different viscosities, densities, shapes & proportions. The major use includes the production of latexes, adhesives, personal care & cleaning products, dispersion & micro- dispersion of chemical & agricultural pesticide formulations. It is suitable for mixing / blending powders as well as through mixing of ointments, creams, lotions, toothpastes, resins, slurries, ceramics, colour, pigments, rubber & other compounds etc. 

PLM is consists of a single blade or double blade with a high dispersion blade ( Emulsifier/Homogenizer). Intimate & homogenizer mixing of products is achieved by planetary motion of beaters & centrally located high speed dispersion blade for vacuum jacketed mixer unit. The PLM consists of two open beaters moving in planetary motion, scraper blade & centrally located high speed homogenizer run by a separate motor to manufacture ointments, creams, suspensions etc. 

It is a stator- rotor high shear mixer. High speed, high shear & higher power are the main characteristics of stator-rotor mixing device. The high shear action creates a forced product flow. The interchangeability of homogenizer blades are possible to suit the mixing requirements of various products. They are used in many process operations like homogenization, dispersion, emulsification, grinding, dissolving, chemical reaction, cell disruption & coagulation.

PLM is also used for blending, mixing & homogenizing powders of various bulk densities by rectangular shaped or heart shaped ( smaller sized mixers) beaters.
