Abstract

An apparatus for producing and analyzing sample materials may comprise a milling device for milling material components, a first metering device for metering a material component into the milling device, a second metering device for metering an activator liquid into the milled material component, a homogenization device for homogenizing the material components and the activator liquid to produce a sample material, a control device that is connected to the milling device and is configured to vary a parameter characteristic for milling intensity of the milling device so that particle size of the material components is altered, and a measuring device for determining a reactivity of the sample material. The present disclosure further concerns a process for producing and analyzing a plurality of sample materials. The process may involve varying at least one parameter characteristic for milling intensity for each sample material produced.
