Transport and Storage
Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT CN ISO Reference Sand 5.1.2 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
