Feldspar Recourses
Feldspar Dressing Plant
Feldspars crystallize from magma in both intrusive and extrusive igneous rocks, as veins, Feldspar is also present in many types of metamorphic rock. Usually rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspar has its widely application and it is the common raw material used in glassmaking, ceramics. In the US, about 66% of feldspar is consumed in glassmaking, including glass containers and glass fiber. To produce feldspar products, like feldspar powders, people invented kinds of feldspar crushers and feldspar grinding machines
Feldspar Crushing Machines
The Moh’s hardness of feldspar is about 3~4 and it belongs to soft material.
Due to the soft hardness, jaw crusher, impact crusher, sand making machine and mobile crusher are usually used as feldspar crusher and ball mill, hammer mill, MTW grinding mill, MTW grinding mill and LM series grinding machine are used as feldspar grinding machines. If the producer use jaw crusher, impact crusher and some other equipments build one feldspar crushing plant, the final products size is able to meet sand size; if producer utilize the feldspar grinding mills, the feldspar powder size is to meet 40-80mesh, 80-120,mesh and smaller. This depends on the market requirements.
Feldspar Ore Crushing Flow
When blast or digger out from the underground or from the mountain, the excavator carry the raw feldspar to the feldspar crushing site and dump the raw feldspar lump to the hopper. Then the vibrating feeder under the hopper feed the raw material to the feldspar crushers steady. The jaw crusher used in primary crushing process will crush it to small lumps until it meet the feed size of the impact crusher used in the secondary crushing process. Through the crushing process, the vibrating screen separates them from the mixture according to the size range. Finally, they are transported to the store pile sits.
In the feldspar grinding plant, the crushed feldspar aggregates will be lifted up by the elevator and fed to the feldspar grinding machines by the electric vibrating feeder. Feldspar will ground between the roller and ring and blow up by the blower. The qualified powders will pass through the classifier and the big powder will be ground again until they meet the requirements. Then the cyclone will bring the feldspar powder to the collector and discharged them. Fines and dusts will be purified by the impulse and bag filter.
