Note: The CS series high-efficiency spring cone crushers are divided into two main types: standard type (B) and short head type (D). The standard type is used for medium crushing, and the short head type is used for fine crushing. Each model is equipped with three chamber types: fine, medium, and coarse, which users can select based on material hardness and required product size. Suitable for iron ore, gold ore, non-ferrous metal ores, granite, basalt, diabase, pebbles, quartzite, sandstone, limestone, and other hard and medium-hard ores and rocks. For explosive environments, explosion-proof motors must be selected. High-abrasion materials are recommended to use high-chrome cast iron or alloy steel liners.

Selection considerations (compared with HST/HPT series hydraulic cone crushers): The core differences between the CS series high-efficiency spring cone crusher and the HST series single-cylinder hydraulic cone crusher, and the HPT series multi-cylinder hydraulic cone crusher lie inthe structural principle, control method, and applicable scenarios.The CS series uses a spring overload protection system, has a relatively simple structure, low investment cost, and high cost-performance ratio. It is an ideal replacement for traditional cone crushers, particularly suitable for projects sensitive to investment costs and with relatively simple working conditions. The HST series adopts a support structure at both ends of the main shaft and a fully hydraulic control system, with high crushing efficiency, 35%-60% higher output than the old spring cone crusher, and a high proportion of cubic final products. The HPT series has a fixed main shaft, an eccentric sleeve rotating around the main shaft, and a PLC integrated control system, with full hydraulic operation; the bidirectional hydraulic safety cylinder provides sensitive iron protection, and five cavity types allow multiple uses with one machine. When selecting models, projects sensitive to investment costs and with relatively simple working conditions are recommended to choose the CS series, while projects with high requirements for output, product shape, and intelligent control are preferred to choose the HST or HPT series.

2. What is the processing capacity of the CS series cone crusher?

The standard type processing capacity is 45-1270 t/h, the short-head type processing capacity is 27-599 t/h, varying depending on model, cavity type, and discharge opening adjustment.

3. What is the maximum feed size of the CS series cone crusher?

The standard feed opening size is 38-369 mm (open side), and the short-head feed opening size is 13-178 mm (open side), varying according to model and cavity type.

4. What is the motor power of the CS series cone crusher?

The motor power ranges from 75-400 kW depending on the model. CS75B/CS75D is 75 kW, and CS400B/CS400D is 400 kW.

5. What is the working principle of the CS series cone crusher?

During operation, the motor drives the equipment transmission shaft through a pulley and V-belt. The transmission shaft drives the eccentric sleeve around the main shaft through large and small bevel gears. The eccentric sleeve drives the moving cone to perform a gyrating motion, causing the moving cone and the fixed cone to sometimes approach and sometimes move away from the crushing wall. The material in the crushing cavity formed by the crushing wall and the crushing surface is continuously subjected to extrusion and impact, breaking it down. The crushed material is discharged from the bottom.

6. What chamber types does the CS series cone crusher have?

Both the standard type and short head type are equipped with three chamber configurations: Fine, Medium, and Coarse, which can meet different process requirements for medium and fine crushing.

7. What is the difference between the standard type and the short head type of the CS series cone crusher?

The standard type is used for medium crushing, with a larger feed opening and a larger adjustable discharge opening; the short head type is used for fine crushing, with a smaller feed opening and a smaller adjustable discharge opening, producing finer final particle sizes.

8. What is the product grain shape of the CS series cone crusher?
