Product Description

Twin Shaft Mixer Disperser

With the help of our sound manufacturing unit and experienced personnel, our company brings forth an exclusive range of Twin Shaft Mixer Disperser for our widespread clients. Our mixer dispenser is widely demanded in several industries for different applications such as plastic pastes, paints & printing inks, ointments, sealing compounds and construction materials. The Twin Shaft Mixer Disperser, which we are offering in the market is well known for its features like sturdy construction, easy installation and long operational life.

 

Further Details:


TO MANUFACTURING AND SUPPLYING:

1 No. 15 / 7.5HP Twin Shaft Mixer - Disperser with hydraulic lifting arrangement for mixing materials of specific gravity ranging from 1-1.3.Premix Capacity 500Lt.

 

PRINCIPAL:

Twin Shaft Mixer  Disperser are designed for processing of highly viscous material containing high percentage of solids which are to be evenly dispersed with small quantities of liquid / solid additives and fillers. The machine consists of a combination of two shafts rotating inside a vessel to achieve these results in short intervals. A low speed centrally located butterfly blade agitators mixes and move the material around the vessel and into the path of high speed shaft. On entering the zone of the high speed shaft the material is subjected to high shear turbulent forces. Which ensures that the entire mass in the vessel is evenly dispersed and homogenously mixed; by periodically varying the height and speed of the shafts and level and the level and quality of productivity can be increased to the desired levels.

 

APPLICATION:

Mixing pastes, breaking down agglomerates dissolving, dispersing, emulsifying and homogenizing viscous materials, such as primers,  pigmented coating compounds,  creams photographic emulsions, adhesive and resin solutions, Printing Inks, Plastisols,  Adhesives, Suffacers, etc.

 

ADVANTAGE:

Outstanding dispersing performance and uniform fineness through intensive shearing action of the new rotor-stator impeller. Almost vertical flow of the circulating materials effects rapid entry of fine powdery constituents into the batch. Drastically reduced mixing times. Minimum heating of the batch. Low energy consumption. Simplified operation and processing. Simple servicing and maintenance. Central control panel with indicators for all machine functions. Low on Power, Highly Versatile, Vibration are Less, Automatic central positioning of change can.

 

FEATURES:

Low-speed butterfly agitator and high-speed disperser disk
Frequency converter drive or hydrostatic drive
Drive power from 7.5 kW to 90 kW, higher power upon request
Batch sizes from approx. 10 to 2500 liters
Removable wall scrapers

 

LIMITATION:

Powder can remain unmixed possibly above the discharge value zone
Small batch size less than 75% of rated capacity cannot be effectively processed
Dead volumes are high.

 

BODY:

The frame will be made from angles and will house the body casting, guide pipe. The base frame will be of 12mm. thick MS plates and will house the entire power pack. The top frame will have the motor and the shaft assembly.

 

AGITATOR MAIN SHAFT:

The shaft will be of 50mm.dia.in SS - 304. MOC. and will be tapered to 40mm.dia. It will be supported by 2nos. ball bearings of size 6212. The bearings will be housed in a MS. Housing which will be bolted to the top frame. The shaft will have a 6½ (150mm) Cowles type impeller blade for dispersion. The Low Speed shaft will be of 75mm dia in SS 304 MOC and will be straight from top to bottom; The Slow speed shaft will have the scraper type arrangement.

 

CENTRAL VESSEL CLAMPING:

Irrespective of what vessel size you use, with the new vessel-clamping device the disperser shaft always remains in the center. The precise parallel guidance of the clamping jaws results from the purely vertical circular movement of the hydraulically operated gripper-type system.

 

DRIVE:

The shaft will be powered by a 15 HP 1440RPM. 3 Phase squirrel cage induction NON-FLP Motor

through "V" groove pulley and belts. The shaft speed can be varied between 0  1440 / 3000 RPM through

a A\C Frequency Drive unit. The Low Speed Shaft will be powered by a 7.5 HP 1440 RPM Motor Coupled with Shaft Mounted Reduction Gear Box having final 75 RPM.

 

SPEED CONTROL:

With a SF Disperser, the continuous speed adjustment from 0 min1 to the maximal stirring shaft speed is realized as standard feature by a maintenance free frequency inverter control. The frequency inverter, PLC and the further control components are accommodated in a separate switch cabinet in the non-ex zone. The maximal speed desired for a dispersing process is pre-selected by a rotary type plus/minus switch. With initially cold and therefore particularly viscous product the dispersing automatic n-tronic adjusts the speed value at which the nominal motor current is just not exceeded. With decreasing motor current or reduced power consumption because of lower viscosity the stirring shaft speed is automatically increased. SF Disperser is constantly operated with maximal power consumption without exceeding the pre-selected limit speed. The result: Better dispersing quality in a shorter time.

 

 

POWER PACK:

The power pack will consist of the following;

1 Nos. 1HP.flange type motor.

1 No.Dowty make pump.

1 No.Direction control valve.

1 No.pressure relief valve.

1 No.Oil filter.

1 No.Pressure gauge.

1 No.hydraulic cylinder of 1000mm stroke

The entire power pack will be enclosed by CRCA14-16 swg. Sheets to prevent dusting and powder deposition.

 

OPTIONAL:

  • Vacuum arrangement
  • Explosion proof construction
  • Heating / cooling arrangement
  • Automatic lifting and lowering of the mixing tools during the mixing process, also under vacuum programmable logic control system
  • Mixing tubs can be heated and cooled

 

 

TO MANUFACTURING AND SUPPLYING:

1no: SS tank of 500Ltr Capacity. (Working 400Ltr)

 

SHELL:         The shell will be 750mm dia X 1000mm height made from 5mm thick SS plates.

BOTTOM:     The bottom will tapered & will be made from 6mm thick SS plates.

JACKET:      The jacket will be 6mm thick MS plates and will cover the working volume of the tank.

WHEELS:      4nos: PP castor wheels will be provided.
