Preface
The RBM™Ribbon Blender range of machines consists of five highly efficient, trough-format
mixers ranging from a capacity of 100 liters to 3000 liters. The machines' stainless steel mixing
blades thoroughly combine dry or moist materials, including powders and pastes, and have a
clearance between the interior wall of the mixing container and blades that allows a high degree of
consistency and homogeneity. Ideal for the chemical, pharmaceutical, and food industries, these
machines have been designed according to GMP principles so that they are easily cleaned and
able to resist chemical damage. Equipped with simple controls and ruggedly built, the RBM™Ribbon
Blender range is straightforward in its operation and maintenance.
The purpose of this document is to support your understanding of the RBM™Ribbon Blender
range’s components, features, functions, and design. With this manual, you will be able to
successfully operate and maintain your RBM™Ribbon Blender machine.
The user manual’s content includes:
• Important safety information
• RBM™Ribbon Blender installation instructions
• Description of the RBM™Ribbon Blender's operation
• RBM™Ribbon Blender maintenance information
• Appendix with supplemental information
