Plough Shear Mixer

Product Details:

Introduction: Plough shear mixers are versatile industrial mixing machines designed for thorough blending of dry powders, granules, and pastes. They are commonly used in industries such as pharmaceuticals, chemicals, food processing, and construction materials manufacturing. Plough shear mixers feature a unique mixing mechanism that consists of multiple plough-shaped mixing elements mounted on a horizontal shaft within a cylindrical mixing chamber. These mixers are known for their ability to produce homogeneous blends quickly and efficiently while maintaining product integrity.

Information: Plough shear mixers are constructed with a sturdy frame and a cylindrical mixing chamber typically made of stainless steel or mild steel. The mixing chamber is equipped with one or more horizontally mounted shafts, each fitted with several plough-shaped mixing elements. These mixing elements can have various configurations, including single or double ploughs, to suit different mixing requirements.

These mixers are suitable for blending a wide range of materials, including powders, granules, fibers, pastes, and cohesive materials. They are often used in processes such as dry powder mixing, granulation, coating, drying, and reaction processes.

Working Principle: The working principle of a plough shear mixer involves the action of the plough-shaped mixing elements as they rotate within the mixing chamber. The process typically follows these steps:

1. Loading: The materials to be mixed are loaded into the mixing chamber through a charging port or inlet. Depending on the mixer's design, the materials may be loaded manually or through an automated feeding system.

2. Mixing: Once the materials are loaded, the mixer's motor is activated, causing the shafts and mixing elements to rotate at a controlled speed. As the mixing elements rotate, they create a complex pattern of fluidization, shearing, and folding motions within the mixing chamber.

3. Fluidization: The plough-shaped mixing elements lift and fold the material from the bottom of the mixing chamber to the top, promoting fluidization and ensuring thorough blending. This action prevents material segregation and ensures uniform distribution of ingredients throughout the mixture.

4. Shearing: The sharp edges of the ploughs shear through any agglomerates or lumps present in the material, breaking them apart and promoting further dispersion and homogenization.

5. Folding: The material is continuously folded and mixed as it moves through the mixing chamber, ensuring that all particles come into contact with each other multiple times, resulting in a homogeneous blend.

6. Discharge: Once the mixing cycle is complete, the blended product is discharged from the mixer through a discharge port located at the bottom of the mixing chamber. Some mixers may feature additional discharge mechanisms such as valves, slides, or chutes to control the flow of the blended product.
