The FKS fluid-bed cooler-sifter is an installation for the treatment of dry silica sand. The sand is cooled down to processing temperature and thoroughly dedusted to reach an excellent quality level.
The FKS is particularly distinguished by:
- simple and reliable operation
- a compact design
- an energy-saving economic concept
Design
The fluid-bed cooler-sifter is fitted with baffle-plates arranged at right angles to the longitudinal walls of the housing and forcing the sand to flow alternately over and under the plates. The resulting spaces, the so-called chambers, house the heat exchangers through which cooling water is circulated. The bottom of the housing is permeable to air but not to sand.
Functioning
While hot sand is fed into the FKS through the inlet, air produced by a fan is blown through its air-permeable bottom. This procedure fluidizes the sand, allowing it to flow freely and to behave like a liquid in communicating tubes. The fluid bed is filled to a controlled maximum level before the sand leaves the FKS again at the discharge end. While the sand flows through the individual chambers it passes along and is cooled by the integrated heat exchangers. At the outlet, a thermostat monitors the sand outlet temperature. In the course of this process, the dust contained in the sand is expelled by the fluidizing air.
The dust is then evacuated into the dust separation filter through a dust gas line.

FLUID BED DRYER DESIGN
The rectangular fluid bed dryer system, CONTACT FLUIDIZERTM incorporates back-mix and plug flow sections. A rotary distributor disperses the wet feed evenly over the back-mix section equipped with contact heating surfaces immersed in the fluidized layer.
The heating surfaces of this fluid bed dryer are designed to avoid deposits and obtain a high heat transfer in the fluidized layer, and they provide a significant portion of the required energy.
Fluid Bed Dryer - CONTACT FLUIDIZER
Therefore it is possible to reduce both the temperature and the flow of gas through the system. This is particularly important for heat sensitive products.
Specially designed perforated gill plates allow handling of oversizes and minimize powder holdup by grade changes.
The heating panels can be inspected or cleaned externally.
Cleaning in place (CIP) of the whole plant is often provided.
Subsequent plug flow sections are used for postdrying and cooling, if required.
ADVANTAGES
Advantages of the CONTACT FLUIDIZERTM - compared to fluid beds without heating surfaces, two-stage flash/fluid bed dryers, or rotary dryers - include its compact design, high thermal efficiency, and low gas throughput

The plants are characterized by an enormous flexibility. By means of individual adaptation of the inlet air conditions which can be adjusted section-wise, the weir adjustment for optimization of the retention time distribution and the integrated filter concept, particles can be formulated exactly according to the customer's demands.
In order to meet the requirements of the EC Directive 94/9 (ATEX 95), the continuous fluidized bed plants can be equipped with certified explosion suppression systems according to the available product data and depending on the risk assessment for dust explosions.
The GMP design allows simple and quick cleaning, especially as WIP systems for automatic cleaning can be integrated.

LABORATORY FLUID BED SYSTEMS
The higher your requirements to be met in the fields of drying, granulation and coating/layering, the more you profit from the OYSTAR HÜTTLIN fluid bed technology. The spraying system of the three-component nozzle guarantees an optimum mixture and a homogeneous coating. The patented process gas distributor blade Diskjet prevents adhesion of the product and offers the best conditions for reliable and reproducible processes.
Regardless which size of fluid bed you require the unique advantages of Oystar Hüttlin laboratory fluid bed systems are identical to the production fluid bed systems. This bears the advantage of precise scale up calculations using the Oystar Hüttlin developed software NexStep.

The Atritor Opposed Jet Mill is probably the most efficient fluid energy mill available. Unlike many mills of this type, it directly entrains the feed material into the high pressure gas for maximum acceleration to near sonic velocity before two opposing streams impact directly in a compact grinding chamber.
The energy imparted to the accelerating particles is instantly expended in inter-particulate collisions and no energy is wasted.
Specific energy consumption is significantly lower than comparable systems.
The grinding chamber is lined with tungsten carbide for maximum resistance to abrasive materials.
An independent classifier is used to ensure the most efficient separation, uncompromised by interference from the grinding process. The oversize fraction is recycled to the grinding system.
Products with top sizes less than 10 microns and mean particle sizes of less than 2 microns are typical.
Dry, oil-free compressed air ensures an uncontaminated product. For heat sensitive materials the air is cooled or hot air will provide some drying capability.
The system is fully automated for un-manned operation.
Each plant is custom designed to specific performance requirements with individual line capacities up to 2t/h.

This innovative air jet mill is capable of fine grinding all kinds of dry products with virtually no contamination.
Through this specialized milling concept, product grinding is entirely autogenous. Gas jets alone create the grinding energy. No tool wear occurs!
An integrated dynamic air classifier in the housing can be infinitely adjusted to the desired fineness. This guarantees exact adjustment of the grinding parameters and reproducible product quality.
Even the hardest of products poses no problem for this machine. In addition, extremely temperature sensitive products such as wax can be processed under continuous operation.

CONDUX CGS 10 and CGS 16 Fluidized Bed Jet Mills, for air jet milling of small batches on a laboratory scale.
The particular grinding principle of this jet mill guarantees a virtually contamination-free, ultra-fine grinding of dry products of all hardnesses. Grinding takes place completely autogenously in a fluidized bed so that no grinding tool wear occurs.
The installed, infinitely adjustable classifier wheel guarantees a defined upper particle size limitation of the ground powder. Grinding results can be reproduced by exactly adjustable machine parameters and can be transposed from the laboratory mill onto a larger, production scale machine.
The complete plant is installed on a base frame and is delivered to the customer where it can be put into immediate operation.
The plant is designed to be modular, so that other modules can be added, such as our ConJet® High Density Bed Jet Mill and High-efficiency Classifier Model CFS / HDS to make a completely versatile laboratory platform.
