DMT polydisperse Calcium Carbonate | AA.22.201.3
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
