PerMix Turbulent Mixer family has two variants, the PTS series Plow Mixer and PTP series Paddle Mixer. These two mixers resemble each other, but with different designs of mixing agitator, thus the applications can be different.

PerMix PTS and PTP Powder Mixers are both very versatile mixing machines, and proven to be able to handle nearly all types of materials including dry materials, powdery, granular, short fibered substance, moist solids with liquids, pasty material and highly viscous masses.

These two mixers can be used for numerous processing, including compounding, fine mixing, dispersing, deaerating, tempering, accelerating chemical or physical reactions, granulating, breaking down agglomerates, etc. It is particularly suitable for difficult processes as mixing trace elements in proportions of up to 1 in 1,000,000 parts, which means you can get the desired mixture proportion of components in as small as 1 g with a batch of 1000kg.

DIFFERENCE BETWEEN PTS & PTP

The main difference between PerMix PTP Paddle Mixer and PTS Plow Mixer is the mixing element: PTS Plow Mixer uses the plough shaped element, while PTP Paddle Mixer uses the paddle element.

Due to this different design of element, PTP Paddle Mixer generates gentler mixing (for turbulence sensitive particles) and requires less power consumption. Besides, the PerMix PTP series Paddle Mixer has a better performance when the materials are with liquid and viscous, for example, slurries; this is because the conventional plough mixing element tends to be sticked and wrapped by the viscous materials while the paddle agitator of PTP Paddle Mixer doesn’t.

BASIC CONSTRUCTION

PerMix PTS Plow Mixers & PTP Powder Mixers consist of a centrally mounted horizontal shaft that rotates within a cylindrical container, ploughs or paddle shaped mixing elements 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, and a complete drive unit.

OPERATION PROCESS

The mixing container is filled from 30% to 70% capacity, allowing space for individual particles to be dispersed within the main area of the mixer. The plough or paddle shaped mixing elements create intense axial and radial movement causing the product to move throughout the mixing space. The shape and angle, together with the adjustment and rotation of the mixing elements and drum wall, cause the product to be lifted off the surface of the drum wall. The product is automatically discharged while the machine is still running so that any segregation is prevented.

SPECIAL DESIGN WITH CHOPPERS

The installation of PerMix Multi-chopper in the basic PTS Plow Mixer or PTP Paddle Mixer enables the breaking down of agglomerates during the mixing process. Together with the mixing element, the PerMix Multi-chopper removes lumps in the initial product, chops pasty adhesives and hinders the formation of agglomeration during the moisturizing of powdered substances. The PerMix Multi-chopper is operated independently by its own motor.

LAB & PILOT APPLICATIONS

PerMix is able to offer lab & pilot size PTS & PTP Powder Mixers for Research & Development purpose. The small size machine is very helpful for customers when the ingredients for R&D are expensive, and to meet the budget limit at the first stage. With the good performance of the lab & pilot mixer, it is easy to scale up for a medium size or even bigger one.

FEATURES & OPTIONS

– Different types of mixing element for a variety of materials
PerMix provides mainly two types of mixing elements: plough (for PTS Plow Mixer) and paddle (for PTP Paddle Mixer). Both have their own advantages: the plough shaped element can easily penetrate through the dense and thick powder or paste materials, while the paddle element can cover an even wider range of viscosity.

– Construction material
We are able to offer mixers with contact part to be built by Carbon steel, SS304, SS316/316L, Titanium, Duplex stainless steel, Hastelloy, etc. For abrasive materials we offer hardened steel as the contact part. Also we produce mixers all by stainless steel in order to meet the high hygienic requirement.

– Continuous operation
We can supply machines for continuous work when a large capacity per hour is needed for the same material. Continuous mixers differ from batch mixers in that the mass flow of the product is from the inlet of the container to the discharge at the opposite end.

– Vacuum drying & deaerating
The mixer can be designed for vacuum drying & deaerating for special applications.

– Heating/Cooling jacket
Jacketed trough for heating/cooling operation by electrical heater, thermal oil or steam

– Spray nozzle & Dripping pipe
Light liquid can be added into the powder by spray nozzles, and viscous liquid can be added by dripping pipe.

– Feeding & Discharging
A variety of feeding & discharging methods can be selected by the customers (e.g. manual, pneumatic, electrical operation).

– Drive system
Drive system by geared motor, cycloidal reducer, worm reducer, belt or chain transmission, etc.

– Extended height bases
Height of our mixers can be defined according to customer’s condition.
