Similar Words: Paddle Blender, Single Shaft Paddle Mixer

PerMix PTP series Paddle Mixers are an innovative design derived from the well-known Plow Mixers (or Ploughshare Mixers, Plough Mixers). The Paddle provides the same mixing performance as a Plow but requires much less power consumption. Due to the less rotation speed of the paddles, the wearing of the mixing element for the Paddle is also less than the Plows. Besides, PerMix Paddle Mixers have a better performance dealing with the viscous/sticky materials, such as slurries, which is because the plough-shaped mixing elements tend to be wrapped by the viscous materials while the paddles don’t.

Compared with the conventional Ribbon Blenders, Paddle Mixers are superior because they are able to mix the material in a more aggressive way while keeping the similar power consumption, due to the fact that the uniquely designed paddles are more pitched than ribbons in a Ribbon Blender and move more materials in a single turn.

The main difference between our PTP Paddle Mixer and PTS Plow Mixer is the mixing element: PTS Mixer uses the plough-shaped element, while PTP Mixer uses the paddle element. PerMix PTP Paddle Mixers can be used wherever the Plow Mixers are used, including but not limited to compounding, fine mixing, dispersing, suspending, emulsifying, deaerating, tempering, accelerating chemical or physical reactions, granulating, breaking down agglomerates, etc.

Both Paddle and Plow are ‘aggressive mixers’ that are well qualified for high mixture ratio processes up to 1:1,000,000, which means the single sample of 1 ppm of a batch volume can still have the right mixture of ingredients.

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 PTP powder 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 designs the full range of paddle mixers, including the lab size (5L full) & pilot size (up to 45L full) models for Research & Development purpose. The small size machine is very helpful for customers when the ingredients for R&D are expensive, thus helping our customer to save their limited budget 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.
