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. In the cone vessel, there are a central tapered ribbon with 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 product.

• High level of accuracy with minor component ratio to be 1:100,000
• Gentle mixing for sensitive materials without generation of heat
• No minimal quantity is required
• Full discharge with minimal residue
• Easy to clean in either dry or wet way
• High heat transfer rate, ideal for heating or cooling process of the powders
• Chopper can be installed for intensive mixing and lump breaking
