Continuous mixer and agglomerator; a rotating shaft with angled blades in flexible chamber where a set of pneumatically operated rollers moves up/down to deform the chamber. Homogeneous mixing and humidification without blockage can agglomerate adhesive material. Although the unit shows compact exterior, it can be operated at high capacity. Product size is in the range of 0.1 to 2mm with porous structure and with narrow particle size distribution.
The more wetting proceeds, the larger agglomerates are produced. However high moisture content changes the agglomerates to highly adhesive nature, which makes continuous operation impossible. Providing self-cleaning mechanism, the Flexomix can handle such adhesive material. The external roller movement flexes the mixing chamber to prevent the wall from build-up of product. This unique self-cleaning mechanism realizes the production of highly moist agglomerates in mass production.
A rotating shaft with blades locales in the center of a rubber made flexible chamber. Feed inlet and two liquid injectors are provided at the top of the equipment.
Blades are installed in three different angles and create strong turbulence to the powder at the max speed to 3000rpm. Powder is continuously fed from the top. Turbulence gives the combined force to the powder swirl, rotation and compression. In this turbulent mixing stage, liquid is injected for mixing and uniform wetting. In case of higher humidification, powder is wetted for large agglomerates and it is repeatedly wrapped up by sprayed liquid drop and grows to porous and large agglomerates.
Rotating speed of rotor and angle of blade is to adjust the strength of turbulence, residence time and dispersing force. Together with these parameters, liquid adding ratio, choice of binder, or feed rate enables to produce agglomerates in various properties.
A self-cleaning mechanism consists of a flexible chamber and the surrounded rollers. This external rollers move up and down to flex the mixing chamber to prevent the inside wall from build-up of product. Practically in the agglomeration process, adhering and peeling of the material is repeated.

A continuous process consisting of weighing feeder, metering at pump and post drying process realized operator friendly and low energy operation at mass production.
Short residence time.
Mixing, wetting and agglomeration complete in 0.2 to 1 second.
Compact machine with large capacity
By continuous process and short residence time, a series of models covers the capacity of 50kg/h to 25t/h.
Saving energy process
Unique agglomeration mechanism realizes the low energy operation of 2 to 4kWh/t.
Highly applicable for high liquid adding ratio
Flexible chamber with self-cleaning mechanism is applicable for high liquid adding ratio and adhesive material.
Extremely high mixing ability
Specially designed rotor gives 3 different movement; swirl, rotate and compression by gravity.
Multi components processing
Agglomeration of 4 liquids and 2 powders are simultaneously processed.
The external rollers moved by compressed air around the flexible mixing chamber prevent the inside wall from build-up of product.
The external rollers double open to left and right from maintenance. Flexible chamber and injectors are easily dismounted. Simple construction and short down time for disassembling and cleaning.
