    General description

    DMT polydisperse limestone AA.22.201.3 is used for testing assembled machines of dust classes M and L.
    The standard test, in which DMT polydisperse limestone AA.22.201.3 is used, is also carried out at DMT GmbH & Co. KG was carried out. Please click here for more information.

    Composition

    The specified particle size distribution is shown in the following table:

    x (µm) Q3(x) (%)
    1.0 10.0
    2.0 22.0
    5.0 75.0

    Transport and Storage

    Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT polydisperse Calcium Carbonate | AA.22.201.3 before use, which can be achieved by mixing with a laboratory tumbler mixer. Please store in a dry and airtight original container.

    Quality ensurance

    In order to achieve reproducible quality, the raw materials and production are strictly controlled. The following quality controls are carried out:

    Monitoring the particle size distribution of raw materials
    Monitoring the particle size distribution of the end product
