MHC Series Multi-cylinder Hydraulic Cone Crushers

MHC Series multi-cylinder hydraulic cone crushers are designed for secondary, tertiary and fine crushing of hard rocks and ores in mining, aggregate and industrial slag processing. Their multi-cylinder hydraulic system supports discharge setting adjustment, overload protection and flexible crushing chamber configurations for controlled product sizing and continuous crushing operations.

Working Principle of Multi-cylinder Hydraulic Cone Crushers

Multi-cylinder hydraulic cone crushers use compression crushing to reduce the size of hard rock and mineral materials.

After entering the crushing chamber, material is compressed between the moving mantle and stationary concave liner. The eccentric movement of the crushing cone creates repeated compression forces, breaking larger particles into smaller sizes.

The closed-side setting (CSS) determines the minimum discharge opening and plays an important role in controlling product size and processing capacity.

The MHC Series incorporates multiple hydraulic cylinders and accumulators around the machine body. When uncrushable materials such as iron enter the crushing chamber, the hydraulic system provides overload relief, allowing the material to pass and helping protect major crusher components.

Applications of Multi-cylinder Hydraulic Cone Crushers

MHC Series multi-cylinder hydraulic cone crushers are designed for demanding crushing operations involving hard and abrasive materials.

1. Metal Mining and Ore Processing

In metal mining operations, cone crushers are commonly used for secondary and tertiary size reduction after primary crushing. The MHC Series is suitable for processing hard ores where stable crushing performance, controlled product sizing and high throughput are important.

2. Quarrying and Aggregate Production

Quarries process hard rock such as granite and basalt into aggregates for construction and infrastructure projects. The MHC Series provides a crushing solution for reducing feed material into different product sizes according to production requirements.

3. Industrial Slag Processing

Industrial slag processing requires equipment capable of handling abrasive and variable feed materials. Multi-cylinder hydraulic cone crushers can be used for suitable slag crushing applications, subject to material characteristics and equipment configuration.

How to Select the Right Multi-cylinder Hydraulic Cone Crusher

Selecting a suitable multi-cylinder hydraulic cone crusher requires matching the equipment specifications with the material characteristics and production targets.

1. Maximum Feed Size

Check the maximum feed size of the selected model and ensure that the upstream crushing equipment delivers material within the permitted range. Oversized feed may cause unstable operation and increase wear.

2. Closed-Side Setting (CSS)

CSS refers to the minimum discharge opening of the crusher. It directly affects the product size distribution and processing capacity.

Buyers should select an appropriate CSS according to the required finished aggregate size and downstream processing requirements.

3. Required Processing Capacity

Determine the target hourly production capacity based on the complete crushing plant requirements. The actual output depends on the selected model, CSS, feed gradation, material hardness, crushing chamber and operating conditions.

Refer to the MHC Series capacity table to compare the nominal output ranges under different CSS settings.

4. Crushing Chamber Configuration

The MHC Series supports standard and short-head crushing chamber configurations. Buyers should select the appropriate configuration according to feed size, crushing stage and required finished product size.

The chamber configuration can be changed by replacing the corresponding mantle liners, concave liners, adapter rings and fixing components.

5. Maintenance and Operating Conditions

Consider the availability of maintenance space, liner replacement requirements, lubrication arrangements and equipment installation height. The MHC Series features an upper-section maintenance design and hydraulic adjustment system to simplify servicing and routine operations.

Multi-cylinder Hydraulic Cone Crushers in a Complete Crushing Plant

In a complete aggregate or mining crushing plant, multi-cylinder hydraulic cone crushers are generally used after primary crushing equipment to perform secondary or tertiary crushing.

For example, jaw crushers can handle primary size reduction of large raw materials before the material enters the MHC Series cone crusher for further crushing.

For production lines requiring additional fine crushing and particle shaping, the VSI Series Vertical Shaft Impact Crushers can be installed downstream to produce manufactured sand and improve aggregate particle shape.

The final equipment arrangement should be determined according to raw material characteristics, target capacity, finished product specifications and site conditions.
