    General description

    DMT Type 3 mineral dust is used as a mineral component in DMT Type 8 test dust.

    Composition

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

    x (mm) q3(x) (%)
    < 0.005 9
    0.005 - 0.01 5
    0.01 - 0.02 8
    0.02 - 0.04 11
    0.04 - 0.075 10
    0.075 - 0.125 7
    0.125 - 0.25 20
    0.25 - 0.5 24
    0.5 - 1.0 6
    1.0 - 2.0 0

    Transport and Storage

    Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Mineral Dust Type 3 | 7.2.2.4 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
