The treatment process of CDW to obtain secondary gypsum powder for binder production: (a) collection of gypsum wallboard CDW; (b) crushing of wallboards with laboratory jaw crusher; (c) …

Primary and Secondary Sizers are sized and selected based on the specific material and lump size to be crushed. Tooth profile selection allows the material to be grabbed and pulled into the crushing zone for maximum efficiency. Sizers use an electric motor to drive the gear reducer, which is mounted directly to the crushing shaft.

EQUIPMENT. APPLICATION. OPERATION. PRIMARY AND SECONDARY CRUSHERS. FEATURES. For industrial beneficiation of primary and secondary raw materials, selection of the most appropriate crushing method plays a key role in the production of specific grain sizes, shapes and surfaces, or to break down multi-component materials.

The main impact is on saving natural resources, which is the logical conclusion, as processing of secondary gypsum requires similar treatment steps as for natural gypsum (crushing, grinding, burning) . One such alternative gypsum source is phosphogypsum (PG), which is the calcium sulphate co-product of the phosphate …

The objective of this work was to investigate the damage characteristics and failure modes of gypsum rock under dynamic impact loading. Split Hopkinson pressure bar (SHPB) tests were performed under different strain rates. The strain rate effects on the dynamic peak strength, dynamic elastic modulus, energy density, and crushing size of …
