Multi-cylinder hydraulic cone crusher structure principle and maintenance

Xingaonai multi-cylinder hydraulic cone crusher is a new generation of high-efficiency cone crusher successfully developed based on more than ten years of crusher research and development experience and combined with advanced foreign technology. It integrates mechanical, hydraulic, electrical, intelligent, automation and other technologies. It is suitable for crushing various ores and rocks with medium and above medium hardness. Based on the traditional multi-cylinder hydraulic cone crusher with fixed main shaft, eccentric sleeve rotating structure around the main shaft and laminated crushing principle, breakthrough optimization of the equipment structure has been carried out, which significantly improves the equipment's performance and crushing capacity. The multi-cavity type After conversion, one machine can be used for multiple purposes, and it is the mainstream crushing equipment in the mining industry.

Structure: 

The structure of multi-cylinder hydraulic cone crusher is relatively complex, mainly including frame, transmission parts, eccentric sleeve, bowl-shaped bearing frame, crushing cone, support sleeve, adjustment sleeve, safety cylinder, lubricating hydraulic part, electronic control part, etc. The support sleeve, adjustment sleeve, safety cylinder and electronic control part are the main research objects of cone crusher intelligent control.

Principle:

Xingaonai multi-cylinder hydraulic cone crusher operates on the lamination principle. The motor rotates through the pulley transmission, and the transmission shaft and a pair of bevel gears drive the eccentric rotation. The crushing cone shaft moves eccentrically, so that the crushing wall surface sometimes approaches and sometimes leaves the crushing wall surface, so that the ore is continuously squeezed and crushed in the crushing chamber. The locking protection cylinder part consists of several locking protection cylinders, iron protection accumulators, buffer accumulator groups and pipelines. The locking protection cylinder mainly plays the role of iron protection and cleaning the crushing chamber. Every two hydraulic cylinders are equipped with a buffer accumulator. During normal crushing, it is used to absorb the impact of the adjustment ring jump caused by a small amount of hard materials during buffering.

Maintenance:

1. Check the vulnerable parts regularly, and pay attention to whether there is wear inside the machine. If there are parts that are worn to a certain extent, they should be replaced in time.

2. Replace the lubricating oil regularly. The lubricating oil is very helpful for the operation and life of the equipment. Generally, it should be replaced every 3 months. When replacing the lubricating oil, the dirt inside the bearing and the bearing seat should be cleaned.

3. Check the quality of the hydraulic oil regularly to prevent water splashing or dust and fiber debris from entering. Too many impurities in the hydraulic oil will not only affect the quality of the product, but also damage some easily worn parts.

4. Keep the inside of the machine dry and clean. After each working day, wipe the surface of the equipment with a clean cloth on the outside of the equipment.

5. Regularly check whether the fasteners of various parts of the machine are loose, the degree of wear, whether there are cracks, etc., and adjust them in place.

Troubleshooting:

1. If the equipment cannot be started normally, check whether the power distribution line in the distribution box is normal and whether the switch is damaged.

2. Check whether there are foreign objects in the crushing chamber before starting to ensure that the equipment can operate normally.

3. If there are abnormal noises, vibrations or hot hydraulic oil during operation, the hydraulic system should be inspected and repaired.

4. When the crushing equipment is not used for a long time, the equipment should be thoroughly cleaned, lubricated and maintained to ensure the service life of the equipment.

From August 25th to October 6th, Xin Gaonai will hold a large-scale promotion with the lowest price of the year.
