In iron ore processing and production, a 500 t/h production line is essential for the efficient operation of the enterprise. As the first crushing equipment of the production line, the rationality of the selection of jaw crusher directly affects the production efficiency, cost and product quality of the entire production line. The following will discuss in detail the selection of jaw crusher in 500 t/h iron ore production line.

 

Recommended Applicable Models

 

• PE1200×1500 Jaw Crusher

 

This model of crusher has a maximum feed size of 1020mm and a processing capacity of 400-800 tons/hour, which is fully adapted to the production needs of 500 tons of iron ore per hour. Its motor power is 160-220kW, with a stable structural design, capable of withstanding the impact and wear of high-hardness iron ore, and very suitable for coarse crushing of iron ore.

 

• JC125 European version jaw crusher

 

This crusher has a processing capacity of 270-800 tons/hour and has significant advantages in design. The design of symmetrical V-shaped cavity and heavy movable jaw assembly makes it highly impact-resistant, especially suitable for high-wear scenes such as iron ore, which can effectively improve production efficiency and equipment life.

Key factors in selection

• Material characteristics

 

Iron ore has a high hardness and its compressive strength is generally between 160-350MPa. Therefore, when selecting, it is necessary to choose a model with a high manganese steel jaw plate and a wear-resistant design, such as the PEW European version series jaw crusher. This material jaw plate can better resist the wear of iron ore and extend the service life of the equipment.

 

• Feed size matching

 

The feed size of the raw ore is an important basis for selection. If the size of the raw ore is ≤850mm, you can choose a PE1000×1200 jaw crusher with a feed opening of 1000×1200mm and a processing capacity of 315-500 tons/hour, which can meet the requirements of feed particle size and output.

 

• Energy consumption and cost

 

Different models of jaw crushers have different motor powers, and energy consumption costs also vary. For example, the motor power of PE1200×1500 is 160-220kW, while the motor power of PE1000×1200 is 110kW. Enterprises need to combine the local electricity budget and comprehensively weigh the purchase cost of the equipment and the energy consumption cost of long-term operation.

 

• Finished product particle size adjustment

 

During the production process, the finished product particle size may need to be adjusted according to different production needs. When the discharge opening is required to have a wide adjustable range, the PE series is preferred, which has flexible discharge opening adjustment; or the JC series is selected, which uses a hydraulic adjustment system, which can more conveniently and accurately adjust the discharge opening size to meet different production process requirements.

 

Matching scheme and manufacturer's suggestion

• Production line matching

In order to form a complete crushing process and improve production efficiency and product quality, the jaw crusher (coarse crushing) → cone crusher (medium crushing) → sand making machine/screening equipment is usually used. The jaw crusher first crushes the iron ore coarsely, breaking the large ore into smaller particles; the cone crusher performs medium crushing to further reduce the ore particle size; the sand making machine can process the ore into finer particles, and the screening equipment is used to screen out the finished products that meet the requirements.

 

• Manufacturer selection

 

When selecting a jaw crusher manufacturer, give priority to manufacturers with experience in iron ore projects. Dahua Heavy Industry provides customized production line solutions based on the specific needs of the enterprise, and provides comprehensive after-sales support in equipment installation, commissioning, maintenance, etc. to ensure the stable operation of the production line.

 

• Precautions

 

Before determining the selection of the jaw crusher, it is recommended to test the actual capacity and wear of the equipment on site through the trial machine service provided by the manufacturer, so as to understand the performance of the equipment more accurately. At the same time, attention should be paid to the long-term maintenance cost of the equipment, including the replacement cycle of wearing parts and the price of accessories, such as jaw plates, bearings, etc. Selecting wearing parts with reliable quality and reasonable prices can reduce the maintenance cost of the equipment and improve the economic benefits of the enterprise.
