Powder mixer type: horizontal plough mixer
Mixer series: SLPS series
Mixing features: plow-type agitator plus horizontal mixer
Function: mix, shear, cut
Usage: especially for the mixing of viscous powders, and fibrous materials
This article provides a detailed introduction to the design features, operating methods, technical parameters, etc of the horizontal plough mixer. It is to help you understand this highly efficient mixing equipment specifically developed for viscous, fibrous, and difficult-to-mix materials.
The plow mixer is a single-shaft forced mixing device, named for the special agitator resembling a plowshare mounted on the main shaft. Unlike ordinary ribbon mixers, the plow mixer features an additional high-speed flying knife device on the side of the cylinder. Through the combined action of the plow blades and the flying knife, efficient and uniform powder mixing is achieved.

This type mixer has the special design features in mixing systems, two different types of mixing system are combined together.
Core Design: Multiple sets of plow-type agitators are mounted in a staggered arrangement on the main shaft, forming a continuous helical distribution.
Design Features | Remark |
Staggered Mounting | The plow blades are mounted in a continuous, staggered pattern; this structural design effectively eliminates mixing dead zones. |
Detachable Design | The plow heads feature a split-type (half-shell) design, facilitating rapid replacement. |
Wear Resistance | Surface hardening treatments such as tungsten carbide spraying can be applied based on the hardness of the materials being processed. |
Adjustable Clearance | The clearance between the plow blades and the vessel wall can be adjusted as needed to accommodate different types of materials. |
Key Function: Mounted on the side of the mixing vessel (typically driven directly by an auxiliary motor), the high-speed chopper serves to break apart and disperse agglomerated materials.
Flying Blade Type | Applicable Scenarios |
Multi-Blade Cross-Type | General-purpose pulverizing and dispersing |
Dual-Leaf "Lotus" Type | Fine dispersion and gentle processing |
Custom Non-Standard Blades | Specific requirements for specialized materials |
Component | Function | Design Highlights |
Horizontal cylindrical body | Material containment | Formed from rolled steel plates; features smooth curved transitions with no dead zones. |
Discharge valve | Discharge control | Pneumatic curved flap valve; fits flush against the curved inner surface of the cylinder. |
Inspection/Cleaning port | Monitoring & Maintenance | Multiple access ports provided to facilitate operation. |
The working principle of the plow blade mixer can be summarized as the dual action of "plow blade tumbling + flying blade dispersion":
● Step 1: The plow blades rotate around a central axis, driving the material to flow circumferentially along the inner wall of the cylindrical vessel. Simultaneously, the blades cast the material outward, perpendicular to their side surfaces, generating a vigorous convective circulation. This design effectively resolves the issue of material stratification commonly encountered in traditional mixers.
● Step 2: As the projected material stream passes through the blade assembly, it is subjected to rapid and forceful shearing and dispersion by high-speed rotating chopper blades. This process is particularly critical for fibrous materials and moisture-agglomerated powders; the blades thoroughly break down any clumps or aggregates, thereby ensuring a uniform blend.
● Step 3: When the addition of liquids (such as oils, flavorings, or water) is required, the liquid is uniformly sprayed onto the material moving within the mixing vessel via a liquid injection device, thereby achieving efficient solid-liquid mixing.
