Horizontal Ribbon Mixer

Ribbon Mixer（images 1）

Introduction

The horizontal ribbon mixer is a highly efficient batch mixing equipment characterized by its unique double-ribbon design (inner and outer helical blades).

These counter-rotating blades move materials in opposing directions, creating intense cross-mixing that achieves high uniformity in just minutes.

It is renowned for its high mixing efficiency, large productivity, low energy consumption, and exceptional reliability.

Details

Drive unitStandard horizontal mixers are driven by gear reducers through direct connection, which has the advantages of high torque, high reliability, and low noise. For large-scale equipment, a combination of gear reducers and belt transmission is adopted to protect the transmission components in case of unexpected situations.

Flexibly detachable ribbon main shaft

Flexibly detachable ribbon main shaftThe ribbon main shaft is connected to the drive shaft flange, allowing for quick disassembly when maintenance or replacement of the shaft is required. The flexible disassembly design enables the U-shaped vessel to be fully welded to the two end plates, avoiding material gaps that may occur with large flange connections on the vessel and reducing residue.

InletsCompared to other types of mixers, the horizontal ribbon mixer offers more flexibility in terms of the lip. It can be designed as fully open, half open, or fully sealed. The fully open design is suitable for situations that require high cleanliness standards and is supported by gas springs for convenient and safe operation.

Discharge valve

Discharge valveGenerally a pneumatic flipper valve is adopted. The circular arc valve is tightly embedded in the cylinder, flush with the inner wall of the cylinder, and free from the phenomena of material accumulation and dead corners for mixing. The reliable edge strip-type sealing ensures no leakage during frequent opening and closing.

Heating/cooling jacket

Heating/cooling jacketVarious types of jackets can be added to the outer body of the mixer, allowing for the cooling or heating of the material by injecting cold or hot media into the jackets. Cooling is typically achieved by pumping industrial water into the jackets, while heating can be achieved by introducing steam or thermal oil.

Main shaft seal

Main shaft sealWhen mixing ultrafine powders, the use of a new type of balanced seal and packing seal enhances the airtightness and effectively prevent the flow of gas and powder between the inside and outside of the vessel.
