Mixers

Exceptional Mixing Accuracy
Material are mixed successfully to an accuracy of 1 part in 1,00,000(0.001%) or better. With no degradation or separation, it throughly blends materials of widely differing densities and particle shapes and sizes.

Short Mixing Time
It achieves a throughly homogeneous mix in 30 to 40% the time of most conventional mixers in the same category such depending on mixing element speeds.

Low Power Consumption
Cone screw mixer (Nouta Mixer) require approximately 50% power over conventional blender.

Gentle Mixing Action
Fragile filaments and flakes are safe from degradation and mixing is accomplished with minimal heat built up and aeration in the product.

Low Floor Space Required
Since mixer occupies less floor space, user can free up space for other plant operations.

Full Load Starting
Its screw agitator begins axially rotating and loosens batch material before its orbiting motion starts. This design feature prevents stalling and permits starting under full load in the event of a power failure. Soft starters are available to reduce excessive torque at start up.

Fast, Complete Discharge
Its unique cone design provides for gravity unloading, gives cleaner and faster batch discharge.

Easy Liquid Addition
Liquids are injected and atomized into the top of the mixer through the hollow shaft of the drive system.

Mixing of Partial Batches
Partial or full load batches are mixing equally well with no reduction in mixing efficiency.

Easy to clean
The top entering drive system provides full product protection with no bearing nor seals in direct contact with the product. Its unique obstruction - free cone shaped design allows for quick and easy cleaning.

Raj Conical Blenders are best suited for mixing, granulation and homogenizing batch process. It handles a range of applications from all types of powders including free flowing to cohesive and moist powders, bulk dry materials to wet cakes and slurries.

Raj Conical Blenders are very sturdy and robust. They consists of a conical Vessel with dished / flat head. The central agitator shaft is driven from top end with gear reducer. A double helical ribbon agitator in the vessel moves the product upward along the outer wall and releases it downward into cavities developed in the middle, simultaneously material is horizontally distributed by the mixing arm and is optimally homogenized.

Mixing time is depending on the agitator speed. In general mixing time is three to four times shorter than the mixers working with a rotating screw.

The drive and bearings are kept outside of the vessel, no gears or seals in the product compartment. The rotating central agitator shaft does not have bottom bearing support there by eliminating any dead spots or difficult areas to clean and there is no danger of product contamination. Discharge of the product is fast and simple as full bore open.

Design Options

• Models with single or double helix.
• Net capacities for 20 to 25000 litres.
• IVarious Material and surface treatment available depending upon product characteristics.
• Cutting rotors for breaking down of agglomerates.
• Liquid adding by ISP system.
• Heating Cooling jackets with insulation.

RAJ Plough Shear mixer is a horizontal mixing system with horizontal, cylindrical drum and horizontally installed mixing shaft.

RAJ Plough Shear Mixer is designed for heavy duty blending of both dry and wet materials. Plough shape shovels mounted on a central shaft with its pointed ends are easily penetrable through the dense powder, pasty mass. The overlapping of shovels coupled with its shape and the high speed of the ploughs produces good mixing action and high turbulence.

The arrangement of mixing tools is the result of many years of development by RAJ process equipments combined with experience based on mixing trials and practical scientific work.

RAJ Plough Mixers are high energy, high shear, and high-speed mixers with cylindrical short aspect ratio mixing chambers. Extra shear can be achieved by adding side cutters or intensifiers. The use of high speed choppers further reduce the product particle size thus resulting in a better mix. RAJ Plough Mixers are available with 'Easy Clean' cantilevered shaft, subject to application.

Applications:

• Quick and homogenous mixing of pastes, rubber, and heavy plastic masses.

• Alternative trough shapes are available to suit specific application requirements,
• Optional wear resistant liner plates provided for abrasive products,
• Jacketed construction available for steam and cooling applications,
• Can be offered for vacuum application,
• Rapid mix times,
• High-energy mixes.

Choppers:
Choppers are working in conjunction with the shovels, intensify the mixing process. They are used for dispersing lumps which are either in the original product or which forms during process, they chop pasty additives or prevent the formation of agglomeration when liquid is introduced to the mix.

The number and type of choppers which are installed is governed by the size of the mixer and the purpose for which it is used. Type of choppers are available for highly specialised mixing process.

Types of choppers offered :

• Multiple choppers.
• Tulip choppers.
• Shearing segment choppers.
• Turbo choppers.

Paddle Style agitators are specially designed to scoop, lift and tumble materials in a gentle, but thorough mixing action. While being mixed, the material travels in a three dimensional "figure 8" pattern. the material is constantly being pulled from the ends of the mixer to the middle of the "figure 8" where the most aggressive mixing is taking place. This unique paddle design is ideal for mixing solids or liquids of various particle size, density and viscosity. The gentle scooping action is ideal for blending fragile ingredients such as nuts or fiberglass strands. Paddle mixers work effectively when filled to as little as 20% of rated capacity, thus allowing flexibility of batch sizes. Paddle style agitators allow easier access for cleaning between batches.


Features of RAJ Paddle Mixer
The paddles are positioned to move the material in opposing lateral directions as well as radially. The paddle design is generally employed where friable materials are being blended.

Paddle mixer consists of several elements: a centrally mounted horizontal shaft that rotates within a cylindrical container, paddles, ploughs or other shaped mixing elements that are attached to the centrally mounted shaft, special openings at the top for feeding materials, flush fitting access doors at the front of the mixer, a flush fitting discharge valve at the bottom of the mixer, which is pneumatically or manually operated, inside a cylindrical conduit and a complete drive unit.

Application
These are horizontal mixers utilized for blending dry material, powdery granular, short fibered, moist solids and liquids together with pasty substances up to and including highly viscous masses.

• Powder and semi dry solid mixing
• Cutting fat into flour
• Addition of oil & liquid into powder
• Mixing soap
• Extending colors
• Breaking down agglomerates
