A reliable source for Paddle Mixers information and leading Paddle Mixers Companies & Manufacturers.
A paddle mixer is a type of mixer utilized in mixing viscous or slurry liquids, solids, and wet-dry mixing. It consists of a central shaft axis that serves to hold the blades. These mixers are most often used in dry mixing but can also accommodate liquid-solid mixing. Read More…

A paddle mixer can mix pastes like mortar, drywall mud, and thin and thick-set liquids. The speed of paddle mixers is about half the RPM of most drills, but they typically have a higher torque to help them power large mixing bits and paddles through thick mud.
Paddle mixers are also known as mud mixers. They can be used as a stand-alone agglomeration device or as a mixing step in a large agglomeration process that uses an agglomeration drum or disc pelletizer.
How Paddle Mixers Work
Paddle mixers are similar to baking paddle mixers: their role is to add water to a powdered material like mortar. A mixing bit or paddle is installed in the paddle mixer, inserted into the mix, and spun until the desired consistency is reached.
Paddle mixers use dual rotating shafts consisting of pitched paddles to create a folding and kneading-over motion inside the trough. Materials and binders can be continuously added to the mixer.
Materials are moved from the bottom of the trough, along the middle, and back down the sides by the pitched paddles to create a homogenous mixture.
Types of Paddle Mixers
The different types of paddle mixers include:
Batch Type Two Shaft Paddle Mixers
These paddle mixers can achieve high-quality mixtures in a very short mixing time at the lowest energy consumption possible. In addition, the product is handled gently and does not get damaged during the process.
These types of paddle mixers consist of two drums that are parallel, each having counter-rotating shafts equipped with paddles. The paddles promote a homogeneous mixture irrespective of the size or density of the particles, with counter-rotation of the paddles that overlap to bring added efficiency.
The design of batch type paddle mixers offers gentle and low shear forces, allowing a rapid mix at low energy consumption.
Paddle Ribbon Mixer
This type of paddle mixer combines outer paddles with inner ribbons while maintaining a counter-directional flow. The outer paddles minimize pinch points at the wall; thus, less frictional heat is introduced than a continuous outer ribbon. With a low amount of energy applied to the mix, it is ideal for fragile and heat-sensitive products.
This type of paddle mixer is a solution for a variety of applications. It ensures rapid and homogeneous blending of even the blending applications that are most difficult due to its triple action.
Continuous High Speed Paddle Mixer
This type of paddle mixer is ideal for the continuous intensive mixing of fine and cohesive powders. In addition, it offers the benefit of short residence times and accurate temperature control. This type of mixer is a horizontal paddle mixer with paddles located in a single or double helical pattern around the rotor shaft.
The typical residence time for this type of mixer is 1 to 20 seconds. The system can be used for various applications, including high-intensity mixing, fine agglomeration, coating, or continuous reaction of gasses with powders.
Due to the close contact between the material and the heated inside surface, it is capable of very high heat transfer efficiency. Depending on the requirements of the process, units can also be fitted with a cooling or heating jacket.
Applications and Uses of Paddle Mixers
Mixing-paddle mixers are utilized in:
Mixing lime for SO2 neutralization, fly ash, municipal sludge for composting facilities, and other processes combining dry and moist feed materials
Agglomeration-granulation of fertilizers, agricultural chemicals, carbon powders, chemical consumer products, animal feed, and flue dust from dust collectors
Conditioning-cement or lime kiln dust, fly ash, iron oxide, foundry dust, lead fume, friction material waste, zinc oxide, copper reverts
