BMC Sigma Mixer Working Principle

During operation, two sigma paddles rotate in opposite directions at different speeds, generating the following effects on the material:

Shearing action
Extrusion action
Folding and stretching action

The material continuously circulates within the mixing tank, achieving uniform mixing. After mixing, the entire material cylinder is tilted via a hydraulic system for rapid discharge.

Hydraulic tilting sigma mixer can use high shear force and strong mixing to make the resin slurry evenly penetrate into the glass fiber, thereby improving the mechanical properties and stability of BMC materials.

Features of BMC Sigma Mixer

1. Powerful mixing capacity

Double "∑"-shaped blades generate high shear force, rapidly dispersing glass fibers and fillers.

2. Thorough discharge

The hydraulic tilting cylinder structure allows for complete material dumping, preventing high-viscosity BMC residue.

3. Controllable temperature

The jacketed structure supports temperature control via steam, electric heating, or cooling water.

4. Robust and durable structure

Suitable for long-term continuous industrial production.

5. Automated control

Can be equipped with a PLC control system for automated operation.

BMC materials produced by sigma mixer is widely used in:

Automotive parts
Electrical insulation materials
Appliance housings
Building materials
Industrial structural components

Hydraulic tilting sigma mixer is one of the most commonly used mixing equipment in the BMC production process. It can efficiently mix resin, glass fiber and filler, and achieve rapid discharge through hydraulic tilting. It is an important piece of equipment for the industrial production of BMC composite materials.
