Latest news, product updates and industry insights from LRMIX — industrial mixer manufacturer specializing in sigma kneaders, dispersers and planetary mixers.
A sigma kneader is a horizontal mixer that uses two sigma-shaped blades rotating toward each other inside a double-trough chamber. The blades squeeze, fold and stretch the material again and again, which makes the machine suitable for thick, sticky and heavy materials that ordinary stirrers cannot handle, such as silicone rubber, adhesives, ceramic pastes and […]
A sigma mixer is an industrial mixing and kneading machine designed for processing high-viscosity, semi-solid, and paste-like materials that are difficult to mix with conventional agitators.Unlike standard liquid mixers, a sigma mixer uses two specially shaped blades, commonly known as Z-blades or sigma blades, to knead, fold, compress, and shear the material inside a horizontal

For small to mid-scale silicone rubber production — pilot operations, multi-formula compounding, and production lines running 3 to 8 batches per shift — a 200L sigma kneader is a practical and cost-effective unit. It is large enough to supply a calender or extrusion line at moderate throughput, and small enough to maintain process flexibility when
A returning customer has placed a second order with LRMIX — two more 100L Screw Extrusion Kneaders, bringing their total to four units of the same configuration. Both new machines are built to the identical single-jacket, screw-discharge spec as the first two, used for ceramic clay mixing. The customer didn’t request any changes to the setup. Why
LRMIX has recently completed the production and shipment of a 5000L horizontal double ribbon mixer for a customer in Malaysia, an agrochemical manufacturer. The machine is built to handle copper sulfate pentahydrate (CuSO₄·5H₂O) — a crystalline material that needs dust kept under control and shouldn’t be broken down too much during mixing. For this application, we specified
