 Jaw crusher, commonly known as jaw crusher, also known as a tiger's mouth, is a kind of crushing equipment. It consists of two jaw plates, a movable jaw, and a static jaw, to form a crushing cavity. It simulates the movement of two jaws of animals to complete the material-crushing operation. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy, and chemical industries. This kind of crusher has the characteristics of a large crushing ratio, high output, uniform product particle size, simple structure, reliable operation, easy maintenance, and economical operating costs.




Jaw crushers are divided into simple swing jaw crushers (simple swing jaw crushers) and complex swing jaw crushers (complex swing jaw crushers). The former's movable jaw only makes a simple arc swing during operation, while the latter's movable jaw also moves up and down while making an arc swing. In addition, jaw crushers are also divided into PE series and PEX series. The PE series jaw crusher has large feed particle size and is suitable for coarse crushing or primary crushing; while the PEX series is suitable for fine crushing or secondary crushing.


Jaw crusher is suitable for processing various coarse, medium, and fine materials (granite, limestone, concrete, etc.) with a side length not exceeding 500mm and a compressive strength not exceeding 350 MPa. It is the first choice for aggregates used in high-grade highway surfaces and hydropower construction. Ideal processing equipment, with its excellent performance and good performance, is widely used in the fields of highway construction, water conservancy projects, and construction gravel processing.


When considering purchasing a jaw crusher, there are several factors to consider.


1. The strength of the crusher manufacturer. The equipment quality of powerful manufacturers is more guaranteed and the after-sales service is better.
2. Crusher model selection. It is necessary to select the appropriate model based on actual production needs to avoid equipment models that are too large or too small.
3. The quality of the crusher. The manufacturing materials, workmanship, and structure of the equipment need to be carefully inspected to ensure that the quality of the equipment meets the requirements.
4. Crusher performance. Factors such as the crushing efficiency, energy consumption, and maintenance costs of the equipment need to be considered to select equipment with excellent performance.
5. Cost of replacement of wearing parts of the crusher. The replacement cycle and replacement cost of wearing parts need to be considered to save costs in long-term use.
6. After-sales service of crusher. It is necessary to choose a manufacturer with complete after-sales service so that you can receive timely technical support and maintenance services during use.
7. Price factors. You need to choose the right equipment within a reasonable budget to avoid being too high or too low.


Additionally, it is crucial to consider the durability and reliability of the jaw crusher. Since it is expected to withstand heavy-duty operations, it should be built from sturdy materials and designed to withstand the harsh conditions of a quarry or mine. To ensure the service life of the machine, regular maintenance and inspection are also required.


When purchasing and using a jaw crusher, you need to pay attention to the following points:


1. Purchase appropriate models and specifications, choose appropriate equipment according to actual production needs, and avoid equipment that is too large or too small.
2. Pay attention to the manufacturing materials, processes, and structure of the equipment to ensure that the quality of the equipment meets the requirements.
During use, it is necessary to regularly check the operating status of the equipment, detect and handle faults promptly, and avoid production interruption due to serious equipment failures.
3. Pay attention to the maintenance and upkeep of the equipment and perform maintenance according to the maintenance procedures recommended by the manufacturer to ensure the normal operation and service life of the equipment.
4. Pay attention to the replacement cycle and cost of wearing parts, and replace worn parts in time to avoid greater failure or damage to the equipment.


In summary, the jaw crusher is an important machine in the mining and construction industries for the primary crushing of rock. Factors such as capacity, feed opening size, power and efficiency, durability, reliability, and safety features should be considered when purchasing a jaw crusher. Investing in high-quality machinery will help you operate efficiently, increase productivity, and ultimately be successful in your mining or construction business.
