Single-Cylinder Hydraulic Cone Crusher for Efficient Crushing Applications
The Single-Cylinder Hydraulic Cone Crusher is a compression-type crushing machine designed for secondary, tertiary, and other fine crushing applications in mining, quarrying, and aggregate production. The GP series uses a hydraulic system to support crushing-process adjustment while the mantle and concave compress material inside the crushing chamber. This type of cone crusher is commonly used after primary crushing to reduce hard rock and ore into controlled product sizes.
Hydraulic Crushing and Adjustable Operation
The working principle of a single-cylinder hydraulic cone crusher is based on continuous compression. Material enters the crushing chamber from the top and is compressed between the moving mantle and stationary concave as the mantle performs an eccentric movement. The changing gap inside the chamber repeatedly compresses the material until particles reach a size suitable for discharge.
The hydraulic system provides an important part of the crusher's adjustment function. The crushing setting can be adjusted according to the required product size and operating conditions. In GP-type cone crushers, hydraulic adjustment can also be used to support chamber clearing and overload protection, helping the machine respond to abnormal conditions during operation.
GP Series Crushing Capacity
The supplied GP Series production-capacity data covers GP100, GP200, GP300, and GP500 models. Depending on the selected model, stroke, maximum feed size, and closed-side setting (CSS), the listed production capacity varies considerably. The supplied table provides different capacity ranges for each configuration, so the correct combination needs to be selected according to the required feed material and final product.
For the GP Series, the supplied data includes motor power of 110 kW for GP100, 200 kW for GP200, 250 kW for GP300, and 315 kW for GP500. The listed maximum feed sizes are 60 mm, 60 mm, 70 mm, and 80 mm respectively for the configurations shown in the first capacity table. These values should be read together with the corresponding stroke and CSS conditions rather than treated as independent specifications.
GP-S Series for Higher Production Requirements
The GP-S Series provides another set of production-capacity configurations. The supplied table covers GP100, GP200, GP300, and GP500 models, with different stroke and CSS combinations and production figures extending to higher capacities than the corresponding standard GP configurations.
The GP-S series can be particularly relevant when the crushing circuit requires a larger feed opening or higher throughput. GP-S-type cone crushers are also described in industry references as configurations intended for efficient secondary or primary gravel crushing, with larger feed openings supporting the handling of larger feed material.
Control of Product Size
Close Side Setting, or CSS, is one of the key operating parameters of a cone crusher. Changing the distance between the crushing surfaces affects the size of the material discharged from the crushing chamber and can also influence production capacity. Generally, a smaller setting is associated with finer crushing, while the appropriate setting depends on the feed material, required product, and overall crushing circuit.
The supplied GP and GP-S tables provide multiple CSS ranges for each model. For example, GP300 configurations in the GP Series include CSS ranges from 100–120 mm through 270–310 mm depending on the listed operating condition, while GP-S configurations provide their own corresponding ranges. These figures should be selected according to the specific chamber and production requirement rather than used as a universal setting.
Applications in Mining and Aggregate Production
Single-cylinder hydraulic cone crushers are widely used for secondary and tertiary crushing of rock and mineral materials. Typical applications include aggregate production, quarrying, mining, and other material-processing operations where primary-crushed material needs further size reduction. GP-type cone crushers are used in secondary, tertiary, and quaternary crushing circuits in aggregate and mining applications.
Depending on the crushing circuit, the equipment can be integrated with vibrating feeders, screens, jaw crushers, conveyors, and other processing equipment. The cone crusher then functions as part of a complete production line rather than operating independently.
Selecting the Right Model
Model selection should be based on the required production capacity, maximum feed size, target product size, CSS, stroke, motor power, and material characteristics. Feed size is particularly important because the crusher chamber must be suitable for the material entering the machine. The desired final product also determines whether a coarser or finer crushing configuration is more appropriate.
The supplied GP and GP-S capacity tables should therefore be used as the primary reference when matching a model to a production requirement. Since capacity changes with stroke and CSS, selecting a model based only on its nominal name or motor power may not provide an accurate indication of actual production.
Technical Data
GP Series Production Capacity
| Model | Stroke (mm) | Max. Feed Size (mm) | Motor Power (kW) |
|---|---|---|---|
| GP100 | 18 / 25 | 60 / 120 | 110 |
| GP200 | 18 / 25 | 60 / 150 | 200 |
| GP300 | 25 / 32 | 70 / 160 | 250 |
| GP500 | 25 / 32 | 80 / 180 | 315 |
The detailed capacity of each model varies according to stroke and CSS, with the supplied table providing the corresponding production ranges.
GP-S Series Production Capacity
| Model | Stroke (mm) | Max. Feed Size (mm) | Motor Power (kW) |
|---|---|---|---|
| GP100 | 18 / 25 | 210 / 250 | 110 |
| GP200 | 18 / 25 | 210 / 280 | 200 |
| GP300 | 25 / 32 | 240 / 320 | 250 |
| GP500 | 25 / 32 | 320 / 420 | 315 |
The detailed GP-S capacity also varies according to CSS and the selected operating configuration. The values above are summarized from the supplied product table; the original detailed capacity ranges should be used for final equipment selection.
Conclusion
The Single-Cylinder Hydraulic Cone Crusher provides a flexible solution for controlled secondary and fine crushing in mining, quarrying, and aggregate-processing operations. Its hydraulic adjustment system, selectable stroke and CSS configurations, and range of GP and GP-S models allow production requirements to be matched with different feed and product conditions. The supplied GP Series covers GP100 to GP500, while the GP-S Series provides configurations for higher-capacity crushing requirements. Final model selection should be based on the complete production-capacity table, feed characteristics, required product size, CSS, stroke, and motor power.
