Mineral filling is a process of filling the bed of welded and cast iron structures with mineral castings; the aim is to increase the damping effect and change the centre of gravity of the equipment by filling it with mineral castings, while keeping the original design unchanged.

The advantages are as follows:

1.No need to redesign the structure;
2.No need to invest in moulds; short running time compared to mineral casting structure;
3.No need to change the basic process of the original product;
4.No need for redesign and integration of auxiliary components;
5.The "parallel engineering design" concept is used to conceal some of the exposed parts in an invisible layout.
