  • This 10L Sigma Kneader Mixer is built for handling sensitive materials like silicone resins in environments where safety is a top priority. It comes with an explosion-proof chiller and a control panel designed to meet strict safety standards. The Sigma-type paddles mix materials at adjustable speeds—up to 42rpm on fast mode and 35rpm on slow. It’s perfect for achieving consistent results, even with reactive materials.

How the 10L Explosion-Proof Kneader Mixer Works

  • The 10L explosion-proof Sigma mixer uses dual Sigma blades to mix organosiloxane copolymer-modified acid resins. The Sigma blades have adjustable speed and are controlled by a frequency converter.

  • To ensure safety, this mixer features an explosion-proof design, enabling safe operation even when handling volatile materials. It also features an explosion-proof limit switch: once the top cover is opened, the mixer stops. A water chiller helps control temperature and prevent damage to heat-sensitive materials during mixing.

  • Discharging utilizes a screw discharge system with a manual ball valve, ensuring clean and rapid discharge of materials.
