Horizontal plowshare mixer

What is a horizontal plowshare mixer?

Horizontal plowshare mixer is a highly efficient and versatile powder mixing equipment, belonging to a high-efficiency intermittent mixer, named because its core stirring component is shaped like a plowshare. This equipment is widely used in chemical, building materials, pharmaceutical, food, feed and other industries, and is suitable for the mixing process of adding a variety of powders, particles and a small amount of liquid (mixing of powders with powders, powders with liquids, powders with particles), especially suitable for processing viscous, agglomerated materials or processes that require crushing and dispersion. With its unique structure and working principle, this equipment can achieve rapid and uniform mixing, and is particularly suitable for processes that add a small amount of liquid or require shear mixing.

Applicable materials

Powdered, granular, and fibrous materials;

Liquids with a small proportion (such as pigments and oils);

Materials with slight agglomeration or need to be broken.

Working principle of horizontal plowshare mixer

The plowshare mixer drives the plowshare blade to rotate at high speed through the main shaft, throws the material up, forms a fluidized motion, and quickly breaks up and mixes the material in the barrel. At the same time, the flying knife (if any) performs strong shearing and breaking action to enhance the interaction between materials and improve the mixing efficiency. The entire mixing process is intermittent, and the degree of mixing can be controlled by time.

Radial motion: When the plowshare rotates, the material is thrown around along the barrel wall.

Axial movement: Specially arranged plowshares push the material to flow along the axial direction of the cylinder.

Convection mixing: Materials flowing in different directions intersect with each other to form convection and achieve uniform mixing.

Shearing and dispersion: Some horizontal plowshare mixers are also equipped with high-speed flying knives to break up agglomerated materials and further improve mixing efficiency and uniformity.

Structural composition

Horizontal U-shaped cylinder: A horizontally placed mixing container with a smooth inner wall or a wear-resistant lining to reduce material residue.

Plow blade stirring device:

Main plowshares: Arranged along the axial direction of the cylinder, when rotating at high speed, the material is thrown from the bottom to the space to form a three-dimensional flow.

Flying knife group: Installed on the side wall of the cylinder, shearing and crushing agglomerated materials at high speed to enhance the dispersion effect.

Drive system: Usually driven by motor + reducer, the speed can be adjusted to adapt to different material characteristics.

Auxiliary devices: Optional heating/cooling jackets, vacuum systems, liquid spraying devices, etc. to meet special process requirements.

What are the advantages of horizontal plowshare mixers?

High mixing efficiency: The general mixing time is between 2 and 10 minutes, and materials with large differences in particle size and density can be mixed. The combined action of the plowshare and the flying knife enables the material to be turbulent, scattered and replaced quickly, and can achieve uniform mixing in a short time.

High mixing accuracy: It can achieve high-precision mixing of materials with large differences in particle size and density, ensuring good quality uniformity of the mixed materials, and it has the best fiber separation performance.

Strong adaptability: It is particularly suitable for occasions with high fiber content and large spray volume. It also has a good effect on the mixing of viscous or colloidal additives, and can also crush and mix agglomerated materials.

Good sealing: The horizontal closed cylinder structure makes it easy to connect the inlet and outlet with the dust removal equipment, reduce dust leakage, and have little impact on the environment of the mixing area. At the same time, it can also prevent external impurities from entering the mixer.

What is a horizontal plowshare mixer used for?

Horizontal plowshare mixers are widely used in building materials, chemicals, pharmaceuticals, agro-pharmaceuticals, food, feed and feed additives, coatings, plastics and other industries, such as solid-solid (powder to powder), solid-liquid mixing (adding a small amount of powder to a liquid), as well as wet granulation, drying and compounding processes. It is especially suitable for mixing viscous or rubbery additives. The equipment can also be specially designed for processing powders, granular products, grains, brittle materials, semi-viscous products and cement concrete materials.

Grease incorporation, vacuum drying

What factors should be considered when selecting a powder mixing and mixing system?

Continuous mixing or intermittent mixing method: Batch processing allows traceability.

Batch size: It is important to find the right balance, as too large a batch may result in uneven mixing.

Mixing time: Shortening the mixing time reduces processing costs and reduces degradation of sensitive materials. However, a balance must be struck between mixing uniformity and cycle time.

Power consumption: Energy efficiency is critical. S&L has extensive experience in designing energy-efficient mixing and stirring systems.

Easy unloading: Unloading capability is one of the key functions of batch mixers. It is essential to ensure that the mixed material is completely unloaded without leaving any residue.

Easy to clean: Proper cleaning is essential for equipment used to mix and stir different materials.
