Conical Screw Mixer / Dryer

TiERMAX offers conical screw mixers /dryers which are widely used for several applications in: chemical, plastics, pharmaceutical, foodstuffs, pigments, coatings, fodder and mining industries. The application of conical screw mixer /dryer is similar to the one of the horizontal type, it is to mix both dry powders and powders with liquid additives.
Conical Mixers can be used also for following processes:

– Vacuum drying

– Homogenizing

– Deaeration

– Cooling

– Heating

Particular Advantages of Conical Screw Mixer / Dryer:

Self-emptying with minimum product retention

Cost-effective mixing technology

Possibility to work with product volume lower than the maximum design capacity

Easy installation on load cells

Possibility to operate under vacuum or pressure

Addition of jackets for cooling, heating or insulating

Very simple cleaning

Cost-effective mixing technology

The mixing effect is obtained by means of a screw which rotates on its own axis, conveying product from bottom to the top, and simultaneously orbits along the inner conical vessel wall.

Our conical screw mixers / dryers are vertical type suitable for batch processes. it is proposed in a wide range of items up to 7.000 lt. of useful capacity.
These conical screw mixers / dryers can be single or double shaft and consist of a conical body, flanged cover (with feeding and inspection doors) and discharging gate, pneumatically operated, fitted at the apex of the cone.
Working principle is based on a progressive mixing system avoiding “dead zones” of non-mixed material. The simultaneous motion of suitable transmissions causes the mixing screw to accomplish two movements: one of rotation on its own axis and one of revolution around the conical vessel wall.
In such a way the screw convey product from bottom to the top causing at the same time a horizontal flow that promote an innermost homogenizing. Thanks to this combined action product, previously conveyed to the top, falls on the product below by generating a three-dimensional mixing movement.

The conical screw vacuum dryer series is a batch dryer suitable for mixing and drying materials such as powders, granules, pastes and viscous slurries, especially when products contain solvents.

Conical screw mixers / dryers are available in several versions to meet specific production requirements. They are manufactured in good quality steel or stainless steel AISI 304 and AISI 316, depending on the type of material being processed. If necessary, special linings can be fitted to minimize abrasion, corrosion or prevent product adhering to internal surfaces.
