PVR Vertical Ribbon Mixer
The PVR Vertical Ribbon Mixers are efficient and versatile blending machines for batch mixing of free-Gowing powders, granules, and pellets.
Vertical Ribbon Mixers are able to give the 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 does it work?
The construction of the PVR series Vertical Ribbon Mixer is very compact: it consists of a cone vessel with the drive unit on the top and a discharge valve at the bottom. In the cone vessel, there is a central tapered ribbon with a very small clearance between its edge and the wall, and additionally, a screw mounted on the central shaft.
The ribbon and the screw move the materials upward from the bottom 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 solution for fragile and heat-sensitive products.
