Hardness: Gypsum is a very soft mineral, ranking only 2 on Mohs scale of mineral hardness. This means it can be easily scratched with a fingernail or a penny. Cleavage: Cleavage refers to a mineral's tendency to break along specific planes of weakness. Gypsum exhibits perfect cleavage in one direction and good cleavage in another direction.
Immediately after final set, the gypsum material is relatively weak and increases in hardness to approximately 68 when the. excess water present is about 7 per cent. This point was reached in about 1 hour. This early increase in properties appears to lie due to further hydration after the final set.

Blake jaw crushers, also as double toggle jaw crushers, are characterized by the position of the pivot of the swing jaw, which is located at the top of the machine. This design allows for a larger feed size and a higher capacity, making it suitable for primary crushing. The motion of the swing jaw in a Blake crusher is predominantly vertical ...
Gypsum is a monoclinic crystalline mineral mainly composed of CaSO 4 ·nH 2 O, which exists in various forms, such as CaSO 4 ·H 2 O, CaSO 4 ·0.5H 2 O and CaSO 4 ·2H 2 O, due to different water contents, as shown in Fig. 4 [42]. There are great differences in the physical properties of gypsum materials with different water contents. Therefore ...
Diamond is the hardest mineral, with a Mohs hardness of 10. Talc is the softest mineral, with a hardness of 1. The Mohs scale is ordinal, where the relative hardness values between one number and another are not uniform For example, diamond (10) is four times harder than corundum (9), while corundum is twice as hard as topaz (8).
A different philosophy applies to the crushing and grinding of Gypsum. Gypsum as a mineral (CaSO4·2H2O) 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 …
