Rock quarrying is actually a reasonably difficult process and rock quarrying equipment is widely used in New Zealand. Distinct tactics are necessary for hard rock quarrying and processing compared with unconsolidated sand and gravel deposits. However, you can find some frequent factors need to be deemed for rock quarrying method, like establishing a viable resource, figuring out the readily available area for development, assessing volumes of waste, overburden as well as other allowances, identifying the requirements for excavation, haulage and processing plant. The rock quarrying is processed in several stages: excavation, drilling, blasting, crushing, grinding, screening, size classification, storage, conveying for additional processing or final application. There will probably be several types of rock quarry equipment involved in these processes.
Rock quarrying jaw crusher mainly consists of main frame, movable( swing ) jaw, eccentric shaft, pulley, toggle plates etc. The electric motor passes power via V-belt pulley to the eccentric shaft to make the movable jaw moves in mesh, therefore, materials in crushing chamber can be crushed;
Rock impact crusher is widely used for secondary crushing, high reduction ratio, terrific cubical shape, much less responsive to sticky material, versatile for quarrying and gravel pit industries, cement, concrete and asphalt recycling, and slag recycling;
VSI crusher is used for fine crushing,limestone aggregate production, limestone sand creating equipment, superior cubically shaped item, enhanced energy efficiency, lower put on charges, enhanced crushing efficiency and management, versatility to operate in various demanding and diverse applications and so on.
