Silos are used for the large-scale storage of a wide variety of bulk solids. The stored bulk solids are then seamlessly supplied to production processes. To achieve this goal, the silo has to be designed as a mass flow silo. The CE 210 trainer provides a practical demonstration of the types of discharge from different silos: mass flow, funnel flow and arching. The type of discharge that occurs is dependent on the flow properties of the bulk solids, the silo geometry and the wall material.

Bulk solids can be transformed from a fixed bed into a fluidised bed when liquids or gases pass through them. The areas of application of fluidised beds include the drying of solids and a wide variety of chemical processes. CE 220 features two transparent test tanks for fluidised bed formation in water and air. A diaphragm pump delivers water from a storage tank into the bottom of the left side test tank. The water flows upwards through a porous sintered-metal plate. On the sintered-metal plate is a bulk solid. If the velocity of the water is less than the so-called fluidisation velocity, the flow merely passes through the fixed bed. At higher velocities the bed is loosened to such an extent that individual solid particles are suspended by the fluid. If the velocity is increased further, particles are carried out of the fluidised bed: transport takes place. Transport is only possible with the experimental unit CE 250. A filter at the top of the test tank holds these particles back. The water flows back into the storage tank.

The terms agglomeration, granulation and pelletisation designate the process of particle size enlargement of solids. This trainer was developed in cooperation with the Department of Mechanical Engineering and Process Engineering at the Niederrhein University of Applied Sciences in Krefeld. A powder (fine material) is continuously fed onto an inclined, rotating dish granulator. A pump delivers granulating liquid to a two-component nozzle. The liquid is atomised over the powder by compressed air. Starting from a small number of moistened particles, a rolling motion produces growing numbers of balls (agglomerates).
