Machine Description:
HOW IT WORKS:In the PerMix PSG series Sigma Mixer, there are two special designed Z-shaped rotating elements installed in a W-shaped chamber, the intersection of which forms a saddle piece and meeting tangentially just above the saddle. They rotate at different speeds (usually in the ratio of 3:2) and in opposite direction.
The mixing action is a combination of bulk movement, smearing, stretching, folding, dividing, and recombining as the material is pulled and squeezed against blades, saddle, and side walls. Continually new layers of material are compressed and folded over one another and are subjected to shearing forces. New surfaces are formed and the components can penetrate.
The blades, which are ground and polished, successively sweep all points of the trough surface during each revolution, at the same time dividing the batch continuously across the saddle piece and thereby rapidly affecting a perfectly homogeneous mix.
DISCHARGE ARRANGEMENTS:
For PerMix PSG Sigma Mixers, There are mainly two ways for discharging the product after mixing:
(1) Tilting Tank
For small machines (PSG-1 to PSG-15), tilting can be done manually with a mechanical type (handlever or handwheel). For greater machines, electro-mechanically or hydraulically powered tilting system is supplied. PerMix supplies the feature that at tilted position, the blade will rotate at low speed (usually 20% of full speed) in reverse direction to aid the discharge by pushing two buttons with both hands.
(2) Extrusion Screw
The extrusion-discharge screw is located in the saddle section and runs in a cylindrical trough tangential to, and below the 2 mixing blades. During the mixing cycle the screw moves the material within the reach of the mixing blades, thus assuring a thorough blending of all the ingredients, and, at the same time, accelerating the mixing process. At discharge time, the direction of rotation of the screw is reversed and the mixed material is extruded through suitable die openings in the side of the machine. The extrusion screw has its own separate drive so that blades and screw operate independently.
Other discharging options are available against request, such as regular ball valves mounted at the trough bottom.

FAQ:
Q: What is your price level compared with European suppliers and local Chinese suppliers?A: Depending on the machine type and size, our price level is 30%-60% less than the European suppliers and 5-15% higher than the big local suppliers.
Q: Are you able to provide tailor-made design and production for the mixers?
A: Yes, in fact more than half of our mixers are tailor made, which is one of our strong points.
Q: Are you able to design and produce other processing equipment?
A: We are open to discuss about it.
