Screw Mixers

Screw Mixers

Screw Mixers are common type of Cone Mixers. They consist of a conical container which houses a continuous flight screw. The screw rotates about its 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.

Typical Applications

Typical applications include dyes, herbal, pharmaceutical, plastic, food, ceramic, agricultural products, shampoos, tooth paste, chocolates, gelatins etc.

Common Features

Exceptional Mixing Accuracy

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

Short Mixing Time

It achieves a thoroughly 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 requires 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.
