Ball mills are a form of mills with grinding bodies. The drums can be opened at the front and loaded with the material to be milled (limestone is recommended) and the milling balls. The drums are mounted on a drive roller and a loose roller with adjustable spacing between the axles. At low rotation speeds the comminution is effected by the balls rolling over the material (cascade motion). At higher speeds, some balls are lifted up the wall, become detached and drop down onto the material (cataract motion). Above the critical speed, centrifugal forces ensure that no more comminution takes place. These motion states can be observed through the transparent fronts of the drums. In order to compare the theoretical power demand with the actual, the power consumption of the drive motor is indicated on a digital display. To assess the success of the comminution, an analytical screening machine is recommended.

A magnetic field of variable frequency and varying strength is produced in a long coil. The voltages induced across thin coils which are pushed into the long coil are determined as a function of frequency, number of turns, diameter and field strength.
Enzymatic Reactors Technical Description Enzymatic Reactorsis designed to study packed bed catalytic reactors. The benchtop unit consists of three transparent reactor columns. Two of them are using a chemical catalyst with different particle size exchange resin. The third one is using a biological catalyst (enzyme). The layout therefore allows to easily compare the performance of the different catalysis. A modern flow injection analysis (FIA) system is mounted on the unit to mix the reagent and product in the correct ratios. Afterwards the product yield can be measured by an optical sensor. A hot water circuit fitted with a temperature controller is used to set and maintain the reaction temperature.
Ion Exchange Demonstration Unit Technical Description Ion Exchange Demonstration Unitis a self-contained benchtop unit, which incorporates two vertical transparent tubes mounted on a panel. The tubes contain the respective cation and anion resins. A manifold arrangement allows the flow configuration to be changed. A rotameter, connecting hoses, a separate sump tank with suction pipe and pump for regenerant, test water or wash solutions complete the set-up. A conductivity meter connected to the outlet of the second ion exchange tube gives a continuous indication of the progress of demineralisation. The unit has been designed to demonstrate the use of ion-exchange resins for either continuous water softening or demineralisation.
Lift Control Experimental model of lift which is truly operational, totally controlled by manual switches to select the floors, set the priority through the program logics.
Venturi Tube Technical Description The Venturi tube can be placed in the measuring section of the test stand with only a few actions. Then fluid mechanics experiments on the energy conservation law (Bernoulli) and on the law of continuity can be performed. The pressure measuring connections on the tube are connected via hoses to the multiple tube manometer belonging to the test stand.
Heat Transfer Technical Description The Heat Transfer Model, designed as an accessory for the , is used for the experimental investigation of heat transfer from a heated rod to an air flow. It comprises a rod oven and a copper specimen. The copper rod is heated in the oven to approx. 110C, before it is placed in the Computer Linked Air Flow Bench. A temperature sensor is built into the specimen; this is connected to the oven and from there transmits its measured data to the Data Logging Unit. By measuring the cooling curve in a flow of air, the coefficient of heat transfer can be determined.
Nozzle Pressure Distribution - Technical Description The benchtop unit enables compressible flow in nozzles to be investigated. A wide range of inlet and outlet pressures can be set with a pressure controller and a needle valve. Easily interchangeable nozzle models (one convergent and two convergent-divergent) are equipped with pressure tappings so the pressure distribution along the flow can be determined. Manometers on the front panel indicate the pressures for air inlet and outlet and up to eight pressures in the nozzle. The air inlet and outlet temperatures are measured using thermocouples and displayed digitally. The airflow rate can be determined using a rotameter. The unit is driven with compressed air.
