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. The equipment is used for homogenization and water replenishment of the crushed material, its body part is welded by high-quality steel. It has the advantages of reasonable structure, steady performance, sturdy and durable, strong adaption, easy operation, low energy consumption, high efficiency, long service life and easy maintenance.
Equipment Specification
Model | Capacity(m3/m) | Length of mixing tank(mm) | Mixing shaft center distance (mm) | Overall dimension (mm) | Weight(t) | Power(kW) |
SJ3600 | 15-25 | 3600 | 360 | 5200 x 2400 x 900 | 5.5 | 37 |
SJ4000 | 30-40 | 4000 | 400 | 6200 x 2800 x 1100 | 7.5 | 55 |
SJ4500 | 50-80 | 4500 | 540 | 7000 x 3400 x 1600 | 11.5 | 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.
