Jiangsu Hongda Powder Equipment Co., Ltd. is a plough mixer manufacturer based in Jiangyin, China, with more than 30 years of experience in powder handling equipment. This guide explains how our horizontal plough mixer works, what the LDJ series offers, how it compares with other mixers, and what to prepare before you send an inquiry.
Horizontal Plough Shear Mixer for Powder, Paste & Fibrous Materials, 100L–3000L
The Hongda horizontal plough mixer is a forced-shear batch mixer for versatile powder and paste blending. It uses a horizontal cylindrical barrel and a horizontal main shaft. Several sets of plough blades sit on the shaft in a staggered arrangement. Independent high-speed flying cutters are mounted on the side of the barrel.The LDJ series covers barrel volumes from 100L to 3000L, so it fits pilot batches, small food plants and large production lines. This plough mixing machine handles four material types:
• Dry powder
• Wet powder
• Paste
• Fibrous materials
Quick specification overview:
• Barrel volume: 100L to 3000L (six models)
• Main shaft speed: 100–300 r/min
• Flying cutter speed: 1000–3000 r/min
• Mixing time: 0–99 min
• Discharge: bottom discharge valve
• Options: liquid spraying system, jacket heating and cooling system
Fluidized Plough Blade Mixing + High-Speed Flying Cutters for Lump-Free Blends
This plough shear mixer uses two mixing actions at the same time. Low-speed plough blades move the whole batch. High-speed flying cutters break up lumps.The plough blades turn at 100–300 r/min. They shovel material from the bottom of the barrel and throw it upward, away from the wall. This creates a mechanical fluidized bed. Particles stay suspended and keep moving, so light and heavy materials, or coarse and fine particles, blend without layering.
The flying cutters run at 1000–3000 r/min. They cut and tear the lumps that the plough blades push through the cutter zone. The result is a more uniform blend, which matters when you add minor ingredients or liquid to a large batch of powder.
LDJ Series Plough Mixer for Food, Spice & Chemical Powders
The LDJ series plough mixer is built for food, spice and chemical powder mixing. As a food powder mixer and spice powder mixer, it offers a compact structure, stable operation and wide applicability.
Typical uses include:
• Spice and seasoning blends
• Food powders
• Chemical powders
• Wet mixing, soft material making and paste mixing

What Is a Plough Mixer? (Ploughshare, Plough Shear & Plow Mixer Explained)
A plough mixer is a horizontal batch mixer that uses plough-shaped blades on a rotating shaft to blend powders, pastes and fibrous materials. The blades work like a plough in a field. They cut into the material, lift it and turn it over.Other Names for the Same Machine
Buyers search under different names. These terms usually describe the same type of equipment:• Plow mixer: the common spelling in the United States
• Ploughshare mixer and plough shear mixer: widely used in Europe and many export markets
• Plough blender and plough mixing machine: common in supplier catalogs
When you compare quotations, check the technical specification, not only the product name.
Why Buyers Choose This Design
Buyers pick a ploughshare mixer when they need stronger mixing than a gentle blender can give. It works well with lumps, damp powders, liquid additives and materials with different particle sizes or densities.How Does a Plough Mixer Work? Plough Blades + Flying Cutters
The working principle has three parts.1. Radial Tossing and Fluidization
The motor and speed reducer drive the main shaft at 100–300 r/min. The inclined plough blades lift material from the bottom of the barrel and toss it upward. The material stays in a suspended, boiling state without deposits or dead corners.2. Axial Convection Circulation
Each group of plough blades is set at a staggered angle. This pushes material back and forth along the length of the barrel. The stable longitudinal flow prevents local buildup and uneven mixing.3. High-Speed Cutter Dispersion
Independently driven flying cutters cut agglomerated, damp and fibrous material as it passes through. With the liquid spraying system, they also atomize the liquid and spread it through the powder.Together, low-speed plough mixing gives an even overall blend, and high-speed shear removes lumps. This is why a plough shear mixer performs well on difficult materials.

Key Features of Hongda Horizontal Plough Mixer
• Horizontal cylindrical barrel: a simple, compact structure that supports stable operation
• Staggered plough blades: three-dimensional circulating mixing with no dead corners
• Independent flying cutters: high-speed shearing for lumps, damp and fibrous material
• Motor and speed reducer: a reliable drive system for the main shaft
• Bottom discharge valve: discharges the batch from the bottom of the barrel
• Optional liquid spraying system: for wet mixing and paste blending
• Optional jacket heating and cooling: for processes that need temperature control
Plough Mixer for Food & Spice Powder Mixing
Spice blending needs even distribution of ingredients with different particle sizes and densities. The plough blade and flying cutter combination handles this well. Because the machine is compatible with fibrous materials, it also suits dry herb and spice blends.For food production, tell us the contact-part material and surface finish you need when you send your inquiry. Stainless steel is the usual choice in food plants, and our engineers will confirm the available options.
Many spice processors grind first and mix second. If your line also needs size reduction before blending, see our spice grinding machine.
Optional Liquid Spraying System for Wet Mixing and Paste Blending
With the optional liquid spraying system, the flying cutters atomize the liquid and disperse it evenly into the powder. This supports wet mixing, soft material making and paste mixing in the same machine.To size the spraying system correctly, prepare this information:
• Type of liquid and its viscosity
• Liquid-to-powder ratio
• Target moisture level of the final blend
Jacketed Plough Mixer with Heating and Cooling Options
The optional jacket heating and cooling system lets you control material temperature during mixing. Buyers use a jacketed plough mixer when a process needs gentle warming or cooling to protect the product.Please tell us the target temperature and the heating or cooling medium you plan to use. We will confirm the jacket design for your process.
Plough Mixer vs Ribbon Mixer vs Paddle Mixer: Which Should You Choose?
Each mixer type has a place. The table below is a general guide. Final selection depends on your material and process.| Feature | Plough Mixer | Ribbon Mixer | Paddle Mixer |
| Mixing action | Fluidized mixing with plough blades | Ribbon agitator moves material in two directions | Paddles lift and turn material |
| Lump breaking | Strong, with high-speed flying cutters | Limited | Limited |
| Liquid addition | Optional spray system with cutters | Possible, depending on design | Possible, depending on design |
| Best for | Powders with lumps, damp powders, pastes, fibrous materials | Free-flowing dry powders | General powder and granule blending |
Applications: Food, Spice, Chemical and Industrial Powder Mixing
The plough mixer suits many powder processing lines:• Food industry: food powders and dry ingredients, mixed as a food powder mixer
• Spice industry: spice and seasoning blends, mixed as a spice powder mixer
• Chemical industry: chemical powders, wet powders and paste materials
• Other industrial mixing: blends that contain lumps, fibers or liquid additives
The machine works best when your process needs a uniform result, lump control or solid-liquid mixing in one step.
