Colloid mill

Riddhi Pharma is one of the top Colloid Mill Manufacturers in India, creating high-quality goods.

A colloid mill is a piece of machinery that is used to reduce the particle size of a solid suspended in a liquid or the droplet size of a liquid suspended in another liquid. The machine comprises an intake that is subjected to a massive shearing action that results in a uniformly sized temporal dispersion and an exit.

Our High Quality Our Products

This is accomplished by providing high degrees of hydraulic shear to the process liquid. Colloid mills are employed in the processes of a liquid dispersion, homogenization, emulsification, creams, mixing, and ointments, among other things.

Following the introduction of the heavier liquid, the lighter material, whether a solid mass or a liquid of varied viscosity, is added to the material to begin the milling process. The materials are both swirled together within the mill at a high rate of speed throughout the milling stage of the operation. It is employed in the reduction of practically all sorts of materials.

Used Latest Technology And Quality Row Material For Products

We are a leading Colloid Mill suppliers in India. The rotor-stator principle is applied in the colloid mill, which is housed in a cylinder vessel.

Product is fed to the operating area of rotor, having a speed of 3000 rpm by specially designed feed device. The product is processed by high shear, pressures & friction between the stator & rotor, & is also subjected to intensive vibration which exerts their force on it by means of pressing & releasing actions. due to the slightly deviating tapering of the milling surfaces of stator & rotor, the angular gap becomes narrower towards the discharge section. This processed product continuously leaves the mill through the drain pipe, if required, it can be recirculated.
1.Leak proof neoprene sealing device.
2.Contact parts can be easily dismantled for cleaning.
3.Coupling provided between motor shaft & rotor shaft for ease in maintenance.
4.Modified design of semi concave teeth in rotor & stator reduces the motor HP & gives better performance in size reduction without damaging the product.
5.Extended bearing housing specially designed to facilitate fine adjustment of bearing clearances or back lash to avoid metal to metal contact of rotor & stator. This unique design provides smooth & consistence all round performance & ong life of rotor & stator.
6.Three oil seals between the Motor & the processing chamber to prevent liquid going in the motor winding, resulting in the burning of the motor.
7.Three way cock system for draining & recirculation of liquids provided as standard. Extra discharge spout rovided as standard for viscous products.
8.DOL Starter with over load relay for protection against single phasing & low voltage.
9.All contact parts are made out of SS. 304 (SS.316 on demand at extra charges). No casting is used for avoiding contamination problems.
10.Flame proof motor & Flame proof rotary switch can be provided on request at extra cost.
11.Special design facilitates adjustments of the grinding gap by an exterior screw by means of handle even during operation.

Technical Specifications Of Colloid Mill

The rotor and stator are placed in such a way that they produce a narrow tunnel through which the material to be reduced in size flows. That is why the process is known as shearing because it literary shears the material into smaller particles. The product is supplied into the hopper, which directs it into the space between the rotor and the stator.

Modifications to fit the needs of the clients!

The product is exposed to a high degree of shearing, cutting, and rubbing between two metal toothed surfaces of rotor and stator and towards the discharge section. If required, the processed product is emptied from the mill via a drainpipe and re-circulated via a three-way cock and re-circulating pipe assembly.
