Customizable Design

Sigma Kneader with Hydraulic Tilting – Customized for Thick Putty

Karvil Machinery 300L heavy-duty sigma kneader, engineered for mixing ultra-thick putty materials under explosion-proof conditions.


This mixer features dual reinforced sigma blades, independently driven at variable speeds to generate the torque and shear force needed for high-resistance mixing. The interior is made from food-grade SUS304 stainless steel, mirror polished for easy cleaning, while the outer frame is carbon steel for strength and stability.
