Paddle Mixers for Industrial Mixing of Bulk Solids, Powders, and Liquids
Paddle Mixers use paddle-shaped agitators that scoop, lift and tumble various types of materials in a gentle, but thorough mixing action. Paddle Mixers are ideal for mixes that have different types of ingredients with dissimilar shapes, sizes, densities and viscosities. Paddles can be used for food mixes that should maintain the integrity of the different particulates. The gentle scooping action is ideal for blending fragile ingredients such as nuts or fiberglass strands. With the paddle action, materials travel in in a 3-dimensional figure-8 pattern constantly pulling from both ends of the mixer to the middle. Welded agitators are the only choice for any mix that requires food-grade sanitation. In addition to food, that can include pharmaceuticals, medical plastics and nutraceuticals.
Industrial Paddle Mixers for Continuous and Batch Mixing
Features and Advantages
Choosing the Right Agitator on Your Paddle Mixer
Welded agitators are the only choice for any mix that requires food-grade sanitation. In addition to food, that can include pharmaceuticals, medical plastics and nutraceuticals. Paddles use a scoop, lift and tumble action for gentle handling of mixes. Often paddles are used in mixes that have different types of ingredients with dissimilar shapes, sizes, densities and viscosities. Paddles can be used for food mixes that should maintain the integrity of the different particulates. With the paddle action, materials travel in in a 3 dimensional figure-8 pattern constantly pulling from both ends of the mixer to the middle.
Applications: Bakery mixes, coffee, soups, dairy powders, ready-to-eat salads, biomass, chemicals, medical grade plastics, sensitive pharmaceutical materials.
Welded Arm/Bolted Paddle
Bolted paddles provide the easiest replacement, so if you are working with abrasive materials that result in wear and tear, you’ll want replaceable parts to reduce the operational costs of replacing the whole agitator shaft. The problem with bolted blades and arms is that for every bolt, you end up with another crevice to clean. If there’s a need for a high level of sanitation or frequent cleaning, it’s better to choose bolted paddles with welded arms for enhanced cleanability. This is where the welded/bolted configuration is a design advantage. If you are using a mixer for multiple types of mixes where you need to clean in between, this is ideal.
Applications: Minerals, some chemicals, building materials, biomass, colored grouts and livestock feed
Bolted Arm/Bolted Paddle
For abrasive applications where wear becomes a concern, it’s inevitable that you’ll need to replace parts. The bolted design allows you to replace arms and blades individually as they wear. Instead of needing to make a full replacement of an agitator, the bolted paddles with bolted arms allow for easy maintenance and longer lifetime of the mixer. The paddles still give the 3-dimensional figure-8 pattern of the welded paddles, but they can be replaced. Bolted paddles are appropriate for mixes where sanitation isn’t much of a worry such as with minerals or with materials that don’t stick, corrode or ferment if a bit of residue remains.
Applications: Minerals, biomass, building materials
A hybrid offers a higher level of agitation than the paddle or ribbon alone. The double-reversing design creates a mixing combination of the figure-8 movement of the paddle style with the scrubbing action of a ribbon blender. The hybrid is best used when products contain a lot of texture or bulk. This translates into increased energy being transferred into the ingredients, and even product levels inside of the trough.
Applications: Cappuccinos, sugar/salt-based spices
Choosing the Right Trough For Your Paddle Mixer
The U-Shaped Trough design is used for ambient conditions or low pressure/vacuum mixing applications and utilizes a flat top cover. The cover can be supplied with inlet nozzles as needed and provisions for dry powder addition. This design allows agitator removal from either the top or end.
Marion U-shaped troughs are:
- The largest in production capacity
- The easiest to clean
- The most commonly used
The Semi-Cylindrical Mixer Trough is built for low pressure requirements. This type features heavy reinforcing along the straight sides, a heavy plate cover design, and a drive that has a concentric shaft reducer with final roller chain drive. This type of paddle mixer trough is curved through 300° so the trough is closely swept by the agitator. "Pinch points" are eliminated on the downsweep side where large, fragile materials can be damaged. Less material accumulates on the upsweep side providing for faster, more thorough mixing.
Our semi-cylindrical troughs are effective for:
- Pastes or slurries
- Reducing the degradation of fragile ingredients
- Allowing for the mixing of oversized materials,
- Mixing sticky or tacky material
Full Cylindrical Trough
This type of paddle mixer is completely cylindrical, offering the best horizontal mixer design for internal pressure or vacuum. In addition, closely swept interior surfaces give excellent heat transfer surface to product volume ratios.
- Agitator sweeps 360 degrees of rotation
- Largest contact surface area for heating or cooling
- Appropriate for vacuum or low pressure applications
