China Nh Series Kneader Is for Mixing Kneading Pencil Lead

The Sigma kneader mixer is consist of mixing chamber, frame support, hydraulic system, electric control system, discharge system and two Z shape blade in the chamber drove by the motor, and the two blade rotating with different speed, but can be controlled by the inverter. The Sigma blade mixer caused by a pair of mutually cooperating and rotating Z blades to produce a strong shearing action so that the semi-dry state or the rubbery viscous plastic material enables the material to react quickly to obtain a uniform mixing.
The NH series kneader is fed with horizontal dual-regulation parallelism, agitating shaft system Σ-type, dual-blade horizontal configuration, opposite rotation and different speeds. When working, the motor is driven by the reducer to the active propeller, and the driven propeller is driven by the counter gear. The spiral blade of the stirring propeller carries the material both axially and radially; it is both squeezing and The separation movement can make the materials fully knead, frustrate, blend, mix and shear, and accelerate the physical and chemical reaction of the materials.Main features and advantages
