Twin Shaft Paddle Mixer For Feed Mills adopts a two-way mixing design, with high mixing uniformity (CV≤5%), strong processing capacity (1-6m³/batch), and can complete efficient mixing in 3-5 minutes, with energy consumption as low as 0.6kWh/t. The equipment is made of high-quality carbon steel or stainless steel, suitable for powder, granular materials and high-fat formula (below 8%), with a residual rate of less than 0.3%, ensuring balanced feed nutrition. It supports customized configuration, including intelligent control system, liquid addition device, etc., to meet the needs of feed mills of different sizes.
The twin-shaft paddle mixer adopts two counter-rotating paddle shafts with a unique paddle design, which can produce strong convection, shear and diffusion effects during the mixing process.
Fast mixing speed: Usually a batch of mixing can be completed within 45-120 seconds, greatly improving production efficiency.
High mixing uniformity: The coefficient of variation (CV) can reach less than 5% or even lower, ensuring the nutritional balance of each batch of feed.
Low residue: The optimized discharge door and internal structure minimize material residue and avoid cross contamination.
The twin-shaft paddle mixer is based on a U-shaped wear-resistant cylinder, with dual-shaft reverse drive and staggered paddles, fully enclosed seal, intelligent transmission and modular easy-to-maintain design, laying a solid foundation for quality and production capacity for feed mills.
Mixing box: welded with 6-12mm thick carbon steel or stainless steel (304/316L), the interior is smooth without dead corners, easy to clean and corrosion-resistant.
Twin stirring shafts: two parallel main shafts, made of alloy steel, surface hardened, and strong wear resistance.
Dual motor + reducer: independently drive dual shafts, power 7.5-75kW (selected according to capacity), support variable frequency speed regulation.
Transmission mode: synchronous transmission by gear or sprocket to ensure the counter-rotation of the two shafts.
Auxiliary system (optional): liquid addition spray device, online moisture detector, PLC automatic control system
The twin-shaft paddle mixer achieves efficient mixing of materials in three-dimensional space through the synergistic effect of two counter-rotating stirring shafts and multi-angle paddles: first, large-scale convection mixing is completed through the axial push of the paddles, and then the cross-shear force generated by the reverse rotation is used to break the agglomerates, and finally the microscopic diffusion mixing is achieved by material throwing. The typical workflow includes three stages: feeding (filling rate 60%-80%), mixing (twin-shaft 20-50rpm speed, 3-5 minutes to complete) and unloading (fast discharge at the bottom, residual rate <0.3%), ensuring that the feed reaches a uniformity of CV≤5% in a short time, while avoiding cross-contamination between batches..
Due to its high-speed mixing performance, the twin-shaft paddle mixer is widely used in livestock, poultry, aquatic products, ruminant feed and premix production.
Livestock and poultry feed: mixed pig complete feed (corn 60% + soybean meal 20% + premix 20%), ensure balanced nutrition such as amino acids, calcium and phosphorus, and increase the daily weight gain of fattening pigs by 5%-8%;
Aquatic feed: mixed shrimp puffed feed (fish meal 30% + flour 40% + phospholipid oil 5%), anti-stratification design to avoid oil sedimentation, and reduce the feed conversion ratio (FCR) by 10%;
Ruminant feed: mixed dairy cow concentrate supplement (corn 50% + cottonseed meal 25% + baking soda 3%), ensure uniform distribution of rumen buffer and reduce the risk of acidosis;
Premix production: mixed vitamin premix (vitamin A 0.01% + carrier 99.99%), with a uniformity of 98%, meeting the high-precision requirements of feed additive companies.
