The most important indicator of the mineral industry index is the wollastonite ore ratio, which is the main basis for delineating and evaluating the deposit. The industrial indicators of the currently used wollastonite ore-bearing rate deposits are shown in the table below.
Other industrial indicators are: thickness that can be collected: ≥1~2m for open mining and ≥1m for pit mining;
The thickness of the stone is removed: the mining is ≥1~2m, and the pit mining is ≥1m;
Stripping ratio: 3
Impurity content: Fe 2 O 3 + TiO 2 ≤ 2%, Cu ≤ 0.3%.

Auto parts laser marking machine for the vast majority of metal or non-metallic materials processing. Auto parts laser marking machine adopts integrated design according to ergonomic principle, beautiful appearance, easy to operate. All the important optical components are imported from Europe and America. The optical path system of the laser marking machine for auto parts adopts the fully sealed structure, with the function of optical path preview and focus indication, which provides reliable guarantee for the machine to work for 24 hours continuously for a long time. Auto parts laser marking machine laser is non-mechanical "tool "" processing, the material does not produce mechanical extrusion or mechanical stress, no" tool "" wear, non-toxic, rarely cause environmental pollution. Auto parts laser marking machine laser beam is very thin, so that the material consumption is very small. |
