There are many types of crushers, some of them are used for coarse crushing, while others are used for fine crushing. Different types of crushers have diversified functions and performance. Here, we will simply analyze performance and characteristics of different types of crushers respectively.
Coarse crushing machine is mainly used to primarily crush bulk materials. Grain size of materials produced by gold ore crusher is larger. Currently, the maximum feeding granularity of domestic gold ore crusher is 9001200 mm( the size of feeding inlet is 9001200 mm), which is especially suitable for exploitation of large mines. gold ore crusher is generally used as the first process of stone and sand production lines. The commonly used gold ore crushers are jaw crusher, gyratory crusher, roll crusher and so on. Jaw crusher machine has the performance characteristics of low noise, little dust, big reduction ratio, even product granularity, simple structure and so on. The features of roll crusher are reliable work, low operating cost, easy replacement of spare parts and so on. Gyratory crusher has high production efficiency, low electric consumption, smooth work, etc, which is suitable for crushing flaky materials.
Fine crushing machine is mainly used for further crushing small pieces of materials. Generally speaking, the materials discharged from gold ore crushers enter the fine crusher for further crushing. The smallest model of domestic fine crusher is 150250 mm( the size of feeding inlet is 150250 mm). Fine crusher is used for secondary crushing in sand and stone production lines. We usually use cone crusher, hammer crusher and impact crusher as the fine crushers. The working principle of cone crusher is the same to gyratory crusher. Cone crusher is only suitable for medium or fine crushing works, which has such features as big reduction ratio, less consumption of wearing parts, low operational cost, hydraulic protection and high degree of automation. Hammer mill crusher has the performance characteristics of even discharging granularity, big crushing ratio, less over ground materials, low energy consumption and so on. But, because of fast abrasion of hammerhead, the application of hammer crusher is restricted in crushing of hard materials. Impact crusher has bigger reduction ratio compared with hammer crusher, which is widely used in medium or fine crushing of limestone, coal, quartz, dolomite, gypsum and so on.
