Silica content in aggregates is a huge factor. The higher the content - the more abrasive the material. Crushing wet material for example when keeping the dust levels lower also contributes to higher wear
Crystalline silica is found in sand, stone, concrete and mortar. When workers cut, crush, drill, polish, saw or grind products containing silica, dust particles are generated that are small enough to lodge deep in the lungs and cause illness or disease including silicosis. silica content wear on crushing plant
The average silica content of the dust was 9. The average cumulative dust exposure was 7.0 mgm3 year and cumulative silica exposure was 0.6 mgm3 year. Significant associations between exposure to concrete dust and a small lung function FEV1FVC ratio, MMEF loss were found, independent of smoking habits and of a history of allergy.
Aug 18, 2020 Compared to compression crushing, impact crushing will create more fines within the circuit which will cause high wear if processing abrasive material. This is why rocks with lower silica content can be more suited for reduction by impact crushers. When compared to cones, impact crushers often have a lower capital cost, but can potentially ...
