Portable Crushing Plant adopts a new design concept. It uses modular vehicle design, able to be transported without disassembly. Besides, it boasts rapid installation and production, safety and environmental protection.
B6X Belt Conveyor adopts C-type steel as the main beam. It takes the modular structure and uses optimized headstock and tailstock. It is equipped with reversed V-type adjustable supporting legs.
According to accumulation and experimental analyses of on-site test data for more than thirty years, TON, a Chinese grinding mill manufacturer, has researched and developed the fifth-generation pendulous hanging grinding mill .
Due to the increasing market demand for the scale, intensification, energy conservation
European Type Jaw Crusher is a new crushing machine, the jaw crusher manufacturer, after the release of traditional jaw crusher.
European Impact Crusher is mainly used in metallurgy, mine, cement, chemical engineering
Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product the feed.
