Mixing is a means whereby mixing of phases can be accomplished and by which mass and heat transfer can be enhanced between phases. Mixers can be used for powder-powder, powder-liquid, liquid-liquid or liquid-air mixing. Mixer is rotary or stationary equipment depending on applications.
Mixer selection is decided by various factors like viscosity, nature of feed, heat sensitivity of feed, nature of final product and etc. We offer mixers of various types and for various applications.
Usually mixers consist of drum, shaft, propeller, gear box & motor. We can offer mixers with horizontal, vertical or inclined shaft depending upon application. Some of the products require pilot trial before selection of mixer, for that we have pilot plant facility for checking suitability of mixer.
Cone screw mixer consists of a conical container which houses a continuous flight screw.The screw rotates about it's own axis and revolves along the walls of the cone. The material of widely differing densities and particle shapes and sizes are mixed homogenously without any degradation. Fragile filaments and flakes are safe from degradation and mixing is accomplished with minimal heat build-up and aeration in the product. The floor space required for this type of mixer is very less. The mixer can be started on full load. Due to the conical shape the unloading of the material is helped by gravity and is complete without any hold-up. Addition of liquids is easily possible by providing atomizing nozzles at the top of the mixer. There are no bearings or seals in direct contact with the product.
Various design options available are :
a)
Capacities from 20 to 25000 liters.
b)
Supported mixing screw at vessel bottom.
c)
Satellite screw.
d)
Sanitary designs for pharma applications.
e)
Laboratory mixers.
f)
Jacket/ Limpet for heating or cooling.
g)
Solvent recovery system
Typical applications include dyes, herbal, pharmaceutical, plastic, food, ceramic, agricultural products, shampoos, tooth paste, chocolates, gelatins etc.
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 Excel 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.
Excel plough shear mixer is a horizontal mixer with cylindrical drum and horizontally installed mixing shaft. The mixer is designed for heavy duty blending of both dry and wet material. Plough shape shovels mounted on a central shaft with its sharp ends easily penetrate through the dense powder and thick pasty mass. Extra shear can be attained by adding side mounted choppers.
design features of plough shear mixer :
a)
hygienic design.
b)
custom built to suit product specific requirements.
c)
teflon coated internals for food and sticky material applications.
d)
wear resistant plates for abrasive products.
e)
jacketed construction for heating or cooling applications.
f)
can be operated under vacuum.
typical applications include homogenous mixing of pastes, rubber, heavy plastic mass, food, pharmaceutical, chemicals etc.
excel plough shear mixer is a horizontal mixing system with horizontal, cylindrical drum and horizontally installed mixing shaft .
excel 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.
Contra Mixer as the name suggest works on the principle of Contra rotation of Blades for simultaneous beating and scraping operation. The mixer is highly versatile and mostly used for manufacturing toothpaste, creams, cosmetics and viscous products.
The mixing Assembly consists of series of paddle type blades of appropriate shape to move the material back towards the center of the container. The paddle type blades are provided on the central shaft which runs through a hollow shaft on which other sets of blades are welded. Both the sets of blades intermeshes with each ther and rotates in clockwise and anti-clockwise direction respectively and one sets also scraps the container wall for thorough and uniform mixing of the material.
The mixer is so designed to withstand high vacuum applied in the process for optimum mixing. Contra mixer is provided with a jacket for cooling or heating as per the application.
We manufacture Contra Mixer with Capacity ranging from 5 litres to 5,000 litres in Material of construction SS 304 or 31 6.
