Process and equipment for determining or influencing the flow properties of solid granular materials.

摘要

By the application of the process and equipment according to the invention flow properties of solid granular materials can be determined even while producing or processing; and by means of the intervening signals derived from measuring results, production and processing can be influenced.
<??>Either in the mass-proportional or in the time-proportional mode of operation, changing one of the parameters in each cycle, the sample-medium is allowed to pass through the sample-holder (101) and using the mass-signal and period-signal thus obtained partly the signal of mass-flow, partly the signal of the density of mass-flow is generated, and from said signals - based on the recognized new correlation - any of the parameters characterizing the technological process is generated by signal processing.
<??>The equipment is provided with a sample-holder (101) with changeable geometry, to the corresponding points of which a type-signal transmitter (102) and an aperture-signal transmitter (103) are connected. Below the sample holder a mass-signal transmitter (109) is arranged. The equipment has an electronic signal processing unit (111) with at least one function-generator and to the input(s) of said unit the outputs of the type-signal transmitter (102), the aperture-signal transmitter (103), a period-signal transmitter (107), the mass-signal transmitter (109) and a device (108) observing the path are connected.
