Extraction (more commonly referred to as quarrying) consists of removing blocks or pieces of stone from an identified and unearthed geologic deposit. Differences in the particular quarrying techniques used often stems from variations in the physical properties of the deposit itself.
The feldspar provides alumina, which prevents devitrivication and improves durability of the glass. The feldspar-rich rock is extracted using open pit methods, then crushed, classified, and dried onsite. Heavy minerals are removed from the material by electrostatic and magnetic processes. Part of the material will be crushed for use as aggregate.
Feldspar Crushing Process
The processing of feldspar may involves physical and chemical processes. Crushing is the primary and integral stage in feldspar production process. Generally, there are three main stages in a crushing circuit processing: primary crushing, secondary crushing, tertiary crushing. It is important to design the layout crushing circuit reasonably, in order to make sure high effective and smooth production process.
There are several factors need to be taken into account to choose right crushing circuit.
- Rock characteristics;
- Crushing process configuration, meaning for example the number of crushing stages used;
- Operating parameters of crushing and screening equipment, typically such variables as speed, stroke, settings, etc. of the crushing machinery, crushing cavity configurations
- Requirements on the end product (crushed rock).
Feldspar Quarry Crushing Machinery
The basic glass crushing process requires only a vibrating feeder and a crusher. According to different final products applications, many other types of equipment are required, such as jaw crusher for primary crushing, impact crusher and hammer crusher for secondary crushing, cone crusher for secondary and tertiary crushing.
Feldspar jaw crusher has the following advantages such as simple structure, easy maintenance, stable performance, high efficiency and low operation costs, so it is the most commonly used stone crusher. Usually the feldspar jaw crusher is used as the primary crusher in feldspar crushing plant.
