As an important crushing equipment, cone crusher is usually used for medium and fine crushing operations. Over the years, Bellian mining machinery manufacturers have put hundreds of cone breakers into use all over the world, and have accumulated rich experience in production applications and equipment maintenance.

At present, there are three common types of cone crushers, namely Simmons spring cone crusher, single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher. Simmons spring cone crusher is a type of cone crusher commonly used in the past and can be used for medium and fine crushing operations. Unreliable, so it is gradually replaced by hydraulic cone crusher with better performance.
The single-cylinder hydraulic cone crusher has simple structure, low cost and stable performance. It is widely used in medium and fine crushing operations. The crushed materials are relatively uniform, the product particle size is excellent, and the needle flakes are few.
Single Cylinder Hydraulic Cone Crusher
Multi-cylinder hydraulic cone crusher can also be used for medium and fine crushing operations, with large crushing force, high output, good product size and shape, and is suitable for the crushing of hard materials. Although the multi-cylinder hydraulic cone crusher is superior, the choice of single-cylinder or multi-cylinder in the whole process depends on the arrangement of the whole process.
Multi-cylinder hydraulic cone crusher
With the development of the industry, Bellian mining machinery manufacturers mainly produce SC single-cylinder hydraulic cone crusher and HPM multi-cylinder hydraulic cone crusher. Taking the multi-cylinder hydraulic cone crusher as an example, the hydraulic system has safety protection and discharge port adjustment functions, provides automatic overload protection, allows iron blocks or other unbreakable objects to pass through, and then the system automatically returns to the original position of the main shaft to effectively protect the main engine.
These two types of cone crushers have multiple models to choose from, and can also be tailored according to the actual needs of customers. They perform well in practical applications and are well received by customers.
But no matter how good the equipment is, you should also pay attention to the relevant experience, so as to have a steady stream of productivity.
1. Installation of equipment
During installation, special attention should be paid to the stability of the foundation. Generally, machinery and equipment should be installed on a stable reinforced concrete surface, and of course they can also be mounted on other vehicles. The thickness of the concrete layer should be determined according to the local geological conditions. When installing the rack, ensure that it is vertical to the base surface and horizontally horizontal. Firm installation can be said to be the first step, after all, the foundation is not firmly shaken.

2. the protection of machinery and equipment
lubricating
Effective lubrication keeps machines running smoothly and productivity higher. When starting the machine, the machine can only be started after the lubrication system is running and the lubricating oil has returned to the oil storage tank for a period of time.
The lubricating oil used in different seasons will be different. The lubricating oil used in summer has a higher viscosity. In winter, running the machine will cause the lubricating oil temperature to rise. The return oil temperature should be controlled within the range required by the equipment. Keep oil temperature within safe operating range at all times.
The oil supply pressure should be controlled within a certain range. If the oil supply pressure is too small, the lubricating oil will not reach the corresponding lubricating parts, and it will not be able to effectively lubricate; The condition of being jacked up makes the top of the large gear contact with the bottom of the bowl-shaped shoe seat and rub against each other, which damages the machine.
Long-term use of lubricating oil will be polluted by the outside world. After a period of time, the oil station should be thoroughly cleaned and replaced with clean lubricating oil to ensure good mechanical lubrication effect.
High-end combined gas station
dust-proof
During the operation of the machine, metal slag will be caused by the wear of the parts, and dust will also enter the machine, which will contaminate the lubricating oil, affect the lubrication effect and service life of the machine, and increase the use cost of the machine, so dust prevention is particularly necessary. Taking the positive pressure dustproof system as an example, the internal air pressure of the crusher is higher than the external air pressure, which can effectively prevent the dust from entering the crusher and keep the lubricating oil as clean as possible, thereby prolonging the life of each friction component and reducing the equipment failure rate. The lubricating oil replacement cycle is longer, which greatly saves the cost of use.
3. Matters needing attention in the production process
pre-screened
When the material is crushed in the crushing cavity, if the space between the materials is small and the space required for the crushing of the large material is insufficient, it is difficult to effectively crush the material. In general, in production, the materials of medium crushing cone crusher generally come from the materials produced by the jaw crusher. Due to the source of raw materials or the insufficient pre-screening capacity of the feeder, the materials produced by the jaw crusher contain a lot of fine materials. Materials will be filled in the gaps of large materials, so attention should be paid to the pre-screening function.
Controlling the composition of the feed particle size
The feed of the fine crushing cone crusher is the product screened in the pre-screening operation, and the particle size range of the feed is small. For the fine crushing cone crusher with different feeding particle size composition, suitable crushing cavity type can be selected, so that the material fills the crushing cavity from large to small.
even feed
When conveying materials, the belt conveyor should be controlled to input the materials evenly. The materials should meet the requirements of the materials broken by the cone crusher. Too much or too little feeding will affect the production efficiency of the machinery and equipment. In addition, pay attention to the discharge of the cone crusher discharge port, and control the speed of the belt conveyor to ensure normal feeding and discharging.
Evenly convey the material into the cone crusher
packed with feed
When the hydraulic crushing production chooses to fill the feed, the lamination crushing has high efficiency. Pay attention to the speed of the material entering the crusher and the corresponding drop relationship. Since the speed of the conveyor remains unchanged, only the drop height of the material can be selected. When filling the feeding, it is necessary to pay attention to the fact that the feeding can not be more or less, and the height of the material in the feeding device must be controlled.
4. the new means of machine maintenance
Intelligent control system
The system can reduce the frequency of equipment overload, ensure that the equipment can achieve greater throughput and lower failure rate, can automatically adapt to changes in feeding materials, can realize automatic compensation for liner wear, and the automatic calibration function can realize one-key operation.
Remote Monitoring and Diagnosis System
Through the Internet of Things technology, the operating status of the cone crusher can be obtained in real time, such as the load situation, the use of the lining plate, and the frequency of failures. By analyzing these data, the possible failures can be judged in advance when the equipment is in normal operation. The equipment is maintained accordingly to effectively reduce the loss caused by equipment downtime.
At present, these two systems have been widely used in various cone crushers of Bellian mining machinery manufacturers, which greatly improves the efficiency of equipment use.
To sum up, in the process of using the cone crusher, attention should be paid to various related matters before and after, and attention should be paid to adopting scientific maintenance methods, which will greatly reduce the probability of problems in production and improve the production efficiency of equipment.
