Product Description

Product Description

Equipment Introduction:

The double-shaft mixer is a core mixing device in the production of fired clay bricks. It achieves efficient homogenization of raw materials such as clay, shale, and water through the mixing paddles (or blades) installed on two parallel shafts. It is suitable for the forced mixing of high-plasticity materials, ensuring the quality of subsequent extrusion and forming.



Equipment Features:
 

• Counter-rotating double shafts: The two mixing shafts rotate in opposite directions, creating a strong shearing and convective mixing effect.
• Adjustable speed: The speed can be adjusted according to the plasticity of the material (usually 15-30 rpm).
• Wear-resistant design: The mixing paddles and liners are made of high-chromium alloy or NM360 wear-resistant steel.
• Sealing structure: Dustproof and leak-proof, reducing clay adhesion.

Product Parameters

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

Equipment Function:

It mixes raw materials such as clay, lean materials (e.g., shale), and water to a uniform plastic state, providing homogeneous clay for extrusion and forming. This directly affects the strength of the brick and the stability of the firing process.
 

Equipment Advantages:

• Achieves a mixing uniformity of over 95%, significantly higher than that of single-shaft mixers.
• Does not easily jam when processing high-viscosity materials.
• Easy maintenance, with paddles that can be replaced individually.
