Feldspars are a group of rock-forming tectosilicate minerals which make up as much as 60% of the Earth's crust.Feldspars crystallize from magma in both intrusive and extrusive igneous rocks, as veins, and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite. Feldspars are also found in many types of sedimentary rock.
Stage 1. Feldspar are transported into raw material hopper by truck, and then lifted into storage silo of main machine by bucket elevator.
Stage 2. Feldspar comes from hopper and feed into main mill uniformly by vibrating feeder, then goes into pipes.
Stage 3. In the grinding process, qualified final product after screening system will go into powder collector by pipes, and then go out from outlet. Unqualified product will go back to main mill and regrind again until it is qualified.
Stage 4. The air flow after purification will go into fan from pipes that up the bag filter, the wind is circular, all other pipes airflow is flow in negative pressure except the pipe from fan to main mill.
