Vertical Ribbon Mixer
The PerMix PVR series Vertical Ribbon Mixer has a similar appearance with the PRB series Ribbon Blender, but stands vertically same as our PNA series Conical Screw Mixer. PVR Vertical Ribbon Mixers are efficient and versatile blending machines for batch mixing of free-flowing powders, granules and pellets.
PVR series Vertical Ribbon Mixers are able to give perfect result of mixing due to the design of an outer spiral type mixing element with an inner screw, rotating together in a conical shape trough, which provides a multidimensional movement of the materials, and a complete discharge of all the mixed material without any residue. The Vertical Ribbon Mixers are also featured with no contamination to the product, due to the fact that the shaft sealing is above the working area, thus no contact with the product.
How It Works?
The construction of PerMix PVR series Vertical Ribbon Mixer is very compact: it consists of a cone vessel with the drive unit on the top and discharge valve at the bottom, and a tapered ribbon mounted on the central shaft. In the cone vessel, there is a central tapered ribbon with very small clearance between its edge and the wall.
The ribbon moves the materials upward along the vessel wall to the top, where the materials then drop by gravity into the center. During this continuous operation, material particles and heat are exchanged quickly which leads to a homogeneous product.
Besides, the material particles are mixed with minimal mechanical and thermal stress, which makes this type of mixer a good sulution for fragile and heat sensitive product.
We offer several types of spiral ribbon for different sizes and applications.
- Construction Material and Finish
We are able to offer our PVR Mixers with contact part to be built in Carbon steel, SS304, SS316/316L, Titanium, Duplex stainless steel, Hastelloy, etc. Standard of internal and external finish can be adopted to the customer's needs. For abrasive materials we offer hardened steel as the contact part.
