Construction

The machine consists of a centrally mounted horizontal shaft that rotates within a cylindrical container, plough shaped mixing elements that are attached to the centrally mounted shaft, special openings at the top for feeding materials, flush fitting access doors in 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.

Operating Principle

The mixing drum of a Plough Mixer is filled from 30% to 70% capacity, allowing space for individual particles to be dispersed within the main area of the mixer. The paddle-shaped mixing elements create intense axial and radial movement causing the product to move throughout the mixing area. The shape and angle, together with the adjustment and rotation of the mixing elements and the mixing drum, 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 DP PerMix Multi-chopper in the basic PTS 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 Model

DP PerMix is able to offer lab & pilot size plow 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

– Different types of mixing element for a variety of materials

DP PerMix provides mainly two types of mixing elements – plough (for PTS Mixer) and paddle (for PTP Mixer). Both have their 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.

The PerMix PFB Fludized Bed Mixer or Twin Shaft Paddle Mixer is a very efficient mixer. Also know as Non-Gravity & Zero Gravity Mixer.

Advantages

• Fast & gentle mixing, typical mixing time is 10-60 seconds for dry, free-flowing materials
• Free particle movement
• Minimal heat and low shear for shear and heat sensitive materials (Due to the fact that low friction without shear in this non-gravity zone is generated, this makes the PerMix PFB series Twin-shaft Paddle Mixer an ideal machine for fragile products that can’t tolerate rough handling, even flakes or spray dried bodies remaining intact after mixing.)
• Easy cleaning and hygienic design with minimal blind corners
• Low maintenance
• Fast discharging & reduced segregation

Working Principle

The DP PerMix PFB series Twin Paddle Mixer consists of paddles with special angles that are mounted on twin shafts in a ‘W’ shaped trough. During operation, the two shafts are rotating in opposite direction.

The paddles sweep the entire bottom of both troughs, and materials are lifted floating between the two shafts (as zero-gravity zone) by the centrifugal force generated by the paddles.

At this weightless zone, mixing of materials of different density is easy and fast because material particle can move freely and randomly, regardless of particle size and density. This brings a rapid and highly homogenous mixing.

Special Designs with Overhead Chopper:

Although the DP PerMix PFB series Twin-shaft Paddle Mixer is featured by its gentle mixing at the weightless zone, it can also achieve rough mixings with additional PerMix Pin Milling Bars to be installed on the top of the paddles.

The PerMix Pin Milling Bars are two rapidly rotating bars with pins and a stationary shroud, which introduce high shear force onto the materials during mixing to break soft lumps and agglomerates. In this case, a fill level of 140% of normal capacity is required.

The PerMix PAM series Vertical Segmented Ribbon Mixer has a similar appearance with the popular PerMix PTP Paddle mixers, but stands vertically with conical bottom, a fact the makes it unique.

PerMix’s PAM Vertical Segmented Ribbon Mixer is a simple, nevertheless, efficient and versatile blending machine for batch mixing of free-flowing powders. It is able to give perfect results for mixing due to the innovative design of an outer spiral type-mixing element with an inner reverse direction mixing arm, rotating together inside a cylindrical with conical bottom shape trough allowing a perfect discharge of the mixed material, with little to no residue.

HOW IT WORKS:

The construction of PerMix’s PAM Vertical Segmented Ribbon Mixer is very compact, it consists of a cylindrical vessel with the drive unit on the top, avoiding any seals in contact with the mixed product and flap type with zero dead zone discharge valve at the bottom, and a jagged ribbon mounted on the central shaft.

In the cylindrical-cone vessel, there is a central segmented ribbon with very small clearance between its edge and the wall. The ribbon moves the materials upward along the vessel wall to the top, where the materials then drop by gravity into the center creating a three dimensional movement of the mixed product. During this continuous operation, material particles and heat are exchanged quickly which leads to a homogeneous product. Besides, the material particles are thoroughly mixed with minimal mechanical and thermal stress, which makes this type of mixer a good solution for fragile and heat sensitive products.

FEATURES & ADVANTAGES:

1) High level of accuracy with minor component ratio to be 1:1,000,000

2) Gentle mixing for sensitive materials without generation of heat

3) Top drive of the mixing device, using only a single top bearing – no seals in contact with the product – no cross contamination.

4) Very low minimal quantity is required, bringing diversity to production

5) Full discharge with minimal residue

6) Easy to clean

7) High heat transfer rate, ideal for heating or cooling process of the powders

8) Chopper can be installed for intensive mixing and lump breaking

9) The mixer can easily be converted to be a mixer / dryer, with the addition of vacuum, heating jacket and other required accessories.M series Vertical Segmented Ribbon Mixer has a similar appearance with the popular PerMix PTP Paddle mixers, but stands vertically with conical bottom, a fact the makes it unique.
