Product Advantages

l Reducing Downtime

MKHP series cone crushers feature bidirectional iron release hydraulic cylinders that allow iron blocks to pass through the crushing chamber, preventing the crusher from stopping due to iron block jams, which can occur with many other manufacturers' crushers. The hydraulic cleaning stroke is large and unaffected by liner wear, reducing the workload required to clear blockages and quickly clean the chamber, thereby shortening downtime and increasing operator confidence. The hydraulic motor-driven adjustment allows for precise discharge opening adjustments and simplifies liner replacement, reducing maintenance workload significantly.

l Ease of Maintenance

MKHP series cone crushers use bronze bushings, which provide higher load capacity in environments with high vibrations and dust. These bushings are cost-effective and can be replaced with standard tools. All parts of the MKHP series cone crushers can be disassembled and maintained from the top or side, and the disassembly of the movable and fixed cones is straightforward, eliminating the need to disassemble the frame and bolts, making daily liner replacements easier.

l Low Maintenance Costs

The high-performance non-contact labyrinth seals prevent dust intrusion and wear, enhancing reliability. The simple design minimizes moving parts in contact with rock and dust. All crusher components have wear-resistant protection, including replaceable components like the movable cone spherical body, main frame seat liner, main frame pin bushing, drive shaft bushing protection plate, counterweight guard plate, main frame liner, and dead corner feeder hopper, thereby reducing maintenance costs to a minimum.

l Flexible Application

MKHP series cone crushers can change the crushing cavity type from standard super coarse to short head super fine by simply replacing the fixed and movable cone liners, adapter rings, and mold block tightening bolts, providing versatile application options.

l Ease of Operation

The hydraulic motor allows for load adjustment of the discharge opening, making it easy to balance the crushing circuit for optimal production efficiency. To integrate the crusher into a plant's DCS distributed control system for fully automatic control, only a hydraulic motor position sensor system is required to track the discharge opening, enabling seamless automation.

Production capacity of crusher

The listed crusher's production capacity is based on "instantaneous" sampling results.

The production capacity table can be used as a preliminary selection tool for MP cone crushers. The data in the table applies to production capacity under conditions of loose feed material with a density of 1.6 t/m³, feed with particles smaller than the discharge opening screened out, and open-circuit operation. In cases where the feed contains a high proportion of fine particles and the equipment operates in a closed circuit, the capacity is 15%-30% higher than in open-circuit operation. The crusher's performance is partly dependent on the correct selection and operation of other components in the production circuit, such as feeders, belt conveyors, vibrating screens, supporting structures, motors, transmission devices, and hoppers.

The following factors can enhance the crusher's production capacity and performance:

1. Select the correct crushing chamber for the material being processed.

2. Ensure the feed size distribution is appropriate.

3. Control the feed rate.

4. Distribute the feed evenly around the 360° range of the crushing chamber.

5. Match the specifications of the discharge conveyor to the crusher's maximum processing capacity.

6. Appropriately select pre-screening and closed-circuit screening screen sizes.

7. Use automatic control devices.

8. Keep the crusher discharge area clear.

The following factors can reduce the production capacity and performance of a crusher:

1. Presence of sticky materials in the feed.

2. Fine particles smaller than the discharge opening exceed 10% of the crusher's production capacity.

3. Excessive moisture content in the feed.

4. Segregation of feed in the crushing chamber.

5. Uneven feed distribution around the crushing chamber.

6. Lack of feed control.

7. Underutilization of recommended horsepower.

8. Insufficient conveyor capacity.

9. Inadequate pre-screening and closed-circuit screening capacity.

10. Blockages in the crusher discharge area.

11. Material that is too hard or too tough.

12. Operating the crusher drive shaft at speeds lower than the recommended full load speed.

The production capacity and particle size listed in the table are based on the average data obtained from the crushing of various types of ores, rocks, and minerals by installed equipment worldwide. For exceptional cases, please consult Metso.
