COLLOID MILLS

The operation is based on the stator / rotor principle: the product reaches the rotor cylinder, exerting the function of disintegration, homogenization, emulsification, dispersion, mixing, in the wet phase.

Colloid mills are used in a wide variety of applications in processing industries. In an annular gap between the stator and the rotor, which can be adjusted by changing the axial position of the stator, product particles are exposed to pressure, shear forces and friction, acting either individually or in combination. All surfaces in contact with the product can be cleaned very easily, without requiring the disassembly of the equipment. The exhaust system and the possibility of a complete and deep cleaning of all the static seals ensures compliance with the various regulations (C.I.P.).

The mills have a modular concept, with different types of construction: vertical, horizontal and horizontal with a separate normalized motor.

SEAL

The grinding zone is separated by a mechanical seal, without empty spaces. According to the different application requirements, radial lip seals, single-acting or double-acting sliding rings, gland packing are used.

 

MATERIALS

The parts that come into contact with the product and the engine coating are made of high quality stainless steel, in accordance with DIN AISI 304, AISI 321, AISI 316 TI. Special hardened chromium steels are mainly used for rotor and stator, for the processing of abrasive products.

 

SUPPLY AND DRAINAGE

Choice of feed through hopper, cochlea, pumps, recycling system; discharge through 3-way valve, for packaging or for sending to further processes.
