How should crushers be selected for the medium and fine crushing operations in a granite crushing production line? A typical granite aggregate production line consists of coarse crushing, medium and fine crushing, sand making and shaping, and screening. Currently, medium and fine crushing operations generally use single-cylinder hydraulic cone crushers or a combination of single-cylinder hydraulic cone crushers and multi-cylinder hydraulic cone crushers. This is mainly because single-cylinder hydraulic cone crushers have a series of advantages over traditional cone crushers.

1. Single-cylinder hydraulic cone crushers are better suited to the production capacity needs of large-scale sand and gravel mines. Domestic sand and gravel mines are becoming increasingly large-scale, with hourly capacities of 1000 tons, 2000 tons, or even several thousand tons gradually becoming the norm. This necessitates crushers with larger individual capacities.

The hourly capacity of a single-cylinder hydraulic cone crusher is significantly greater than that of a traditional cone crusher. Taking the Shibang Group HST single-cylinder cone crusher as an example, its hourly capacity can reach 2000 tons, better meeting the production capacity needs of large-scale mines.

2. Single-cylinder hydraulic cone crushers better meet the intelligent needs of large-scale sand and gravel production lines. As sand and gravel mines become larger, the requirements for intelligent equipment also increase to reduce equipment maintenance and operating costs, as well as labor costs. Taking the Shibang HST single-cylinder hydraulic cone crusher as an example, it can achieve automated control of the production process, such as constant discharge port control, constant power control, and other operating modes, thereby reducing production and operating costs while effectively controlling the quality of finished aggregates.
