Industrial double shaft mixer for high-capacity fertilizer production. Twin-shaft design for superior mixing uniformity. Handles wet & sticky materials. 5-20T/H capacity. ISO/CE certified.
The Double Shaft Mixer (also known as Twin Shaft Mixer) is a heavy-duty industrial mixing machine engineered for high-capacity fertilizer production lines. Its dual-shaft design — featuring two counter-rotating shafts with interlocking paddles — delivers unparalleled mixing intensity and uniformity, making it the preferred choice for large-scale organic and compound fertilizer plants.
Unlike single-shaft mixers, the double shaft configuration creates a fluidized mixing zone where materials are simultaneously lifted, sheared, and circulated in three dimensions. This makes it especially effective for wet, sticky, or high-viscosity materials that single-shaft mixers struggle with.
💡 Each shaft is independently driven — if one motor trips, the machine stops safely without damaging the gearbox.

Q1: How is the double shaft mixer different from a standard horizontal mixer?
A: The double shaft mixer has two counter-rotating shafts that create an overlapping mixing zone, achieving better uniformity (≥97% vs ≥95%), faster cycle times (2-4 min vs 3-6 min), and better handling of wet/sticky materials.
Q2: What is the maximum moisture content it can handle?
A: Up to 35% moisture content. For materials above 35%, we recommend pre-drying or selecting a mixer with optional scraper attachments.
Q3: Can the paddle angle be adjusted?
A: Yes. The paddle angle can be adjusted to optimize for different material characteristics — steeper angles for faster mixing, shallower angles for gentler handling of fragile materials.
Q4: What maintenance is required?
A: Routine greasing of bearings (weekly), paddle wear inspection (monthly), and gearbox oil change (every 6 months). Wear-resistant paddle tips are designed for easy replacement.
Q5: Do you offer PLC automation for batching control?
A: Yes. We can integrate PLC control with load cells for automatic weighing and batching, as well as VFD for adjustable mixing speed.
