Conical Ribbon Mixer
Vertical ribbon blender for fast homogeneous mixing
S&L Conical ribbon mixer is a vertical ribbon blender for fast homogeneous mixing, consisting of an outer ribbon mixer, inner reverse screw mixer, vertical conical shape vessel, and drive unit. The material circulates and rises as it is operated by the outer ribbon mixer, while the inner reverse screw presses the material downward along the shaft to complete the mixing process.
The vertical ribbon blender is equipped with a nitrogen gas inlet, which provides full protection by filling nitrogen gas throughout the process to prevent material oxidation reactions. The mixer also has an external cooling jacket, which can lower the temperature of the materials through nitrogen gas circulation or cooling water circulation. The bottom of the mixing machine is connected to a hemisphere valve, ensuring residue-free discharge.

Conical Mixer with CIP
S&L conical ribbon mixer can also be equipped with a Clean-in-Place (CIP) system to enhance its performance for hygienic production. This system allows for thorough cleaning of the mixer without disassembly. It involves installing washing devices and performing manual preparatory steps to initiate the cleaning process. The CIP system operates in a fully automated mode through programmable logic control (PLC), ensuring complete cleaning. After wet cleaning, it is essential to dry the mixer using air. By utilizing the CIP system, cross-contamination between batches can be prevented, thus ensuring the quality of the finished products.
Conical Mixer with Jacket
The dimple jacket is a commonly used type of jacket for dryer mixers. It consists of a thin external shell attached to the vessel shell using spot welds. The cooling or heating medium flows through the jacket, allowing for temperature control of the mixer. With advancements in material processing, mixers are increasingly being used for multi-functional mixing purposes. A dryer mixer can be utilized for mixing materials with a maximum water content of 70%, which can then be dried through the heating jacket combined with vacuum technology. In some cases, the drying effect can reduce the water content to as low as 0.05%. The basic design of a dryer mixer involves a stationary horizontal cylinder that is loaded from the top and discharged from the bottom. The standard mixing tools are plow-shaped and radiate from a horizontal shaft supported by outboard bearings. Other mixing tool designs are also available to suit specific requirements.
Operating based on the proven "fluidized bed" mixing principle, this dryer maintains the materials in a mechanically fluidized suspended state. This allows for intimate contact between reacting mediums, such as gas-solid or liquid-solid, and facilitates efficient heat transfer between them and the heat transfer surfaces of the mixer.
Cooling or heating: Various types of jackets can be added to the outside of the mixer cylinder to achieve cooling or heating of the materials by injecting cold or hot media into the jackets. Cooling is typically achieved by pumping industrial water, while heating can be achieved by introducing steam or thermal oil.
Conical Mixer with Retractable Rotor
The screw agitator pull-out design is an ideal choice for hygienic mixing application, which allows for easy access to the mixing chamber, reduces downtime for cleaning, and prevents cross-contamination between batches. The drive system ensures that the top cover and vessel can be easily separated, facilitating efficient cleaning of the mixer. The screw agitator pull-out design is particularly useful for dealing with sticky materials that may adhere to the vessel or agitator. This design provides a good way to ensure complete cleaning, thereby avoiding any potential pollution or cross-contamination issues. Additionally, this design allows for quick and easy receipt changing, enabling users to increase the efficiency of their mixing processes.
