Feldspar Purity FAQ
Q
How to maintain feldspar whiteness during fine crushing?
A
Traditional hammer or impact mills rely on high-speed dynamic collisions. This aggressive action causes heavy metal friction that sheds iron dust directly into the raw ore, polluting the feldspar matrix and ruining the firing whiteness required for premium ceramics and glass.

Hydraulic Double Roller Crusher
The APEX 2PGY Hydraulic Roller Crusher solves this by operating at a very low speed (60–80 RPM). Instead of striking, it utilizes massive static hydraulic pressure to squeeze the material. This low-friction framework drastically eliminates mechanical wear. Combined with our specialized manganese-free alloy roller liners, it guarantees an iron-free processing environment to safeguard your product grade.
