This machine is a twin-shaft paddle mixer equipped with a W-shaped tank and two paddle shafts that rotate in opposite directions, stirring the materials in both axial and radial directions. The materials are fluidized (in a weightless state) within the mixing zone, repeatedly lifted and then dropped, creating cross mixing. As a result, high mixing uniformity can be achieved in a very short time. 【Features】 ■ Excellent mixing uniformity in a short period ■ High durability and heavy-load design suitable for abrasive materials ■ Minimization of residues with a large discharge valve ■ Capable of mounting a high-speed crusher device (for deagglomeration) on top ■ Suitable for heat-sensitive and fragile materials ■ Compatible with both batch and continuous processes *For more details, please download the PDF or feel free to contact us.

We would like to introduce our "Vertical Ribbon Mixer." The mixing blades (ribbons) are designed to move the materials in a three-dimensional manner. The spiral ribbons transport the materials upward at the outer periphery of the tank, while gravity allows the materials to flow downward at the center of the tank. This cyclical movement of upward and downward flow achieves high-quality and uniform mixing. It is suitable for fragile materials and heat-sensitive materials due to the reduced mechanical and thermal stress during mixing. 【Features】 - Compact spiral ribbon structure with no mixing dead space - Equipped with a high-speed chopper for disaggregation - Design with no risk of lubricant leakage - Complete discharge structure - CIP cleaning compatible - Supports heating/cooling jackets and vacuum specifications *For more details, please download the PDF or feel free to contact us.
