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.

The experimental set-up is arranged on a clearly laid out board, which is mounted on the basic unit. The pipe connection between the basic unit and the additional module is via self-locking Schrader valves. Individual components of the system, in this case the compressor, fan, heater, humidifier and solenoid valves, are actuated using the software included with the basic unit. The represents a model of an air conditioning system with recirculating or fresh air operation. The refrigerating capacity is generated by an evaporator. A fan moves the air to be conditioning through a ventilation duct containing an integrated air humidifier and an adjustable air valve. Heating elements can be used to heat the air. Solenoid valves enable the unit to be operated with a capillary tube or an expansion valve as the expansion element.

Training System Temperature Control Technical Description This compact teaching / training unit offers every opportunity to learn the fundamentals of process control through experimentation on a temperature control system. The experimentation set-up is mounted on a solid housing which accommodates all the electronics. A metal bar, which is thermally insulatedwith cladding, is heated or cooled at one end by a Peltier element. Three temperature transducers along the axis of the bar allow the variation in temperature along the length of the bar, and hence the associated thermal lags, to be obtained for differing operating conditions. A dial-gauge thermometer offers the advantage that the temperature can be read off directly at any time. The temperature ismeasured using a thermal resistor (PTC). The transducer output signal is sent to the software controller. Theoutput signal from the controllerinfluences the operating voltage of the Peltier element andhence the heating power. A fan that dissipates part of the heating energy can be activated by the software to investigate the influence of disturbance variables. The powerful state-of-the-art software is an integral part of the training system, embodying the principle of hardware/software integration (HSI). It enables the experiments to be conducted and evaluated in a user-friendly manner. The software has network capability. The link between the practice system and the PC is made via a USB port. The clearly structured instructional material sets out the technological fundamentals and provides a step-by-step guide through the experiments

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.

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.
