Equipment Introduction:
The Twin-Shaft Mixer is a core mixing equipment in clay brick production. It utilizes two parallel shafts with paddles (or blades) to homogenize raw materials (e.g., clay, coal gangue, water). Designed for high-plasticity materials, it ensures uniform mixing for subsequent extrusion molding.
Technical Data:
| Model | Capacity | Length of Mixing Chamber | Mixing Shaft Center Distance | Weight | Dimension | Power |
| SJ3600 | 15-25 m³/h | 3600 mm | 360 mm | 5.5 t | 5200*2400*900 | 37 |
| SJ4000 | 30-40 m³/h | 4000 mm | 400 mm | 7.5 t | 6200*2800*1100 | 55 |
| SJ4500 | 50-80 m³/h | 4500 mm | 540 mm | 11.5 t | 7000*3400*1600 | 90/110 |
Features:
1. Counter-Rotating Shafts: Two shafts rotate oppositely for intense shearing and convective mixing.
2. Adjustable Speed: RPM typically 15-30, adaptable to material plasticity.
3. Wear-Resistant: Paddles and liners made of high-chromium alloy or NM360 steel.
4. Sealed Design: Dust-proof and leak-proof, minimizing clay adhesion.
Function:
Mixes clay, lean materials (e.g., coal gangue), and water into a uniform plastic state, providing homogeneous material for extrusion. Critical for brick strength and kiln stability.
Advantages:
1. Mixing uniformity >95%, far superior to single-shaft mixers.
2. No jamming even with high-viscosity materials.
3. Easy maintenance with replaceable paddles.
The mixer focuses solely on blending, while the mixer-extruder combines mixing and extrusion, ideal for compact production lines.
