Double-shaft mixer: A high-efficiency solution for continuous NPK mixing
In large-scale NPK compound fertilizer production, the mixing process is the "core checkpoint" determining nutrient uniformity—no matter how high the batching precision, uneven mixing can still lead to localized nutrient deviations in the finished product. For continuous production lines with an hourly output of 10 tons or more, traditional intermittent mixers require frequent start-ups and shutdowns, waiting for unloading, which has become an efficiency bottleneck. The double-shaft mixer is specifically designed for continuous production and can seamlessly integrate with automatic batching systems. With a mixing uniformity of over 98% and continuous feeding and discharging capacity, it has become the preferred supporting equipment for medium to large-scale NPK production lines.
