F ORMS 网页2019年7月8日 A different philosophy applies to the crushing and grinding of Gypsum. Gypsum as a mineral (CaSO42H2O) is number 2 on the Mohs scale of hardness; only Talc is softer. This would lead one to believe that it should be easy, to crush, like coal for example, and our equipment was formerly designed on this basis. Within the past 20 网页2023年2月28日 To optimize the subsequent screening of the gypsum waste the crushing machine is designed to produce an even flow of the gypsum waste to suit the rest of the production process. Safe and reliable crusher for milling of gypsum waste. With a substantial weight of up to 20 tonnes, a torque of 13,000 newton metres and reverse operation in the 网页2023年2月28日 The flexural strength of concrete including Cupola slag as an aggregate diminishes due to the slag's higher crushing value [11, 16]. Higher free CaO concentrations ( Table 5 ), which promote expansion and more micro-cracks, and EAF's angular, rough, and porous structure led to poor mechanical properties of the RCC mixture when fine EAF 网页If the size of the gypsum material is large, we often use a jaw crusher and impact crusher as the coarsely crushing machine.
