Shashvath Fabricators And Engineers

Vasai, Thane, Maharashtra

We manufacture and supply Communicating Mill from Thane, Maharashtra. It is used for reducing size, or milling in pharmaceutical industries, and chemical factories. The reduction of particles takes place through the knife edges mounted on the rotor. It has a minimized downtime with reduced noise level. The beaters are made of 410 quality stainless steel and a movable machine.

Construction and Operation : The product is poured from the top through in feed hopper and material falls on the rotor blades beater assembly for milling or pulverization. Due to the knife edges mounted on rotor, the downsizing of particle takes place and through sieve material gets pushed outward from the bottom opening. Knife edges can be removed for cleaning very easily.

Details :

• GMP point of view machine is provided with S. S. cladding on base, S. S. belt guards, S. S. cover on motor. No exposed painted surface on top of the machine. Motor rails, screw and guide rods are chrome plated.

• Beaters assembly bearings are in a separate pillow blocks for ease in maintenance.

• Very less down time as only beaters assembly will have to be reversed (and not the complete chamber) for making it knife to impact forward or vice-versa which can be done by single operator.

• Fixed beaters assembly is provided as a standard supply which increase the output by 10% to 30% reduce noise level and also ease to clean as there are no cavities. (If product demands, swing beaters assembly can be provided.)

• Beaters and shaft are of stainless steel 410 quality and beaters are further hardened and chrome plated. Beaters are fitted on a splined shaft.

• Transmission of heat to the chamber from bearings is minimum as they are away in separate pillow blocks. This facilitates to some extent in processing of heat sensitive products.

• Castors provided for mobility and breaks can be applied for fixing machine at one place.

• Machine is available in plain & water-jacketed models. Flame proof electricals can be provided on demand at extra cost.

Salient Features :

• Design is cGMP - Current Good Manufacturing Practices compliance

• All Product contact parts AISI 316/ 316L & non contact parts AISI 304.

• High speed milling, granulating, pulverizing, mixing and size reduction of wet & dry material.

• Easy and simple to change knife to impact forward vice-versa by reversible chamber.

• Dynamic balanced beater assembly bearings are in a separate pillow block at outside chamber.

• Wide range of sieve of perforated and wire-mesh.

• Fitted on castor wheels for easy mobility

Optional Features :

• Jacketing chamber for water cooling.

• AC frequency drive for variable speed,

• Explosion proof motor and push button,

• Fixed / swing type beater assembly

• Uniform feeding system with feeder screw with variable drive.

Safety Features : Interlocked throat hopper and belt guard & Over load relay protection.

Shashvath Planetary Mixer is ideal for mixing of wet / dry materials. It has a homogeneous mixing action. The planetary motion of the beater enables faster and better mixing of material at a considerably lesser time. Slow speed is used for dry mixing with less dust generation and faster speed for kneading operation during wet granulation portable mixing bowl with top mounted agitator has a dual advantage of material transfer and no risk of gland packing contamination.

CONSTRUCTION

The basis of mixing system of Planetary Mixer is a combination of planetary- rotating paddle agitator. 2 Nos. Anchor type agitator with cross baffles rotates in anti-clockwise direction with planetary motion in there axis. While paddle revolves in clockwise direction with planetary action, generating a disturbance in the normally circular flow pattern and dampen vortex formation. The mixing blade and planetary action having dual speed. In addition, adjustable scrapers are utilized to prevent the build-up of a stagnant film between the agitator and the vessel, and assure efficient heat transfer to product during heating and cooling steps. The speed of the agitator and the counter paddle can be varied separately.

The Product container is castor wheel mounted for easy load and unload to the machine. The top mixing blade assembly is motorized up and down during container loading and unloading. The mixing container is jacketed for heating / cooling and completely enclosed. The product container can be designed to operate under vacuum; mixing can then be performed without entrainment of air. Top lid of the product container having charging pot for binder adding, eye glass window and light glass.

Drive Mechanism For Beater :

Consist of the following

1. Suitable HP 1440/2880 RPM DUAL Sped TEFC Motor to work on 415 V, 50 c/s 3 Phase AC supply line, mounted on MS plate.

2. Worm reduction gear box coupled to the motor through belt and pulley arrangement.

3. Epicyclic gear box coupled to the motor through belt and EPICYCLIC gear train arrangement to achieve planetary motion.

4. Suitable HP 1440 RPM TEFC motor to work on 415V 3 phase 50 C/s AC supply line for High Shear Emulsifier. ( optional )

5. The above item are assembled on the top plate which is supported on a Cast iron sliding sleeve with MS gussets.
