In the mining, washing, and utilization of coal, the first crucial step is crushing. Among these processes, the jaw crusher, with its robust structure, reliable performance, and wide applicability, has become the undisputed "king of primary crushing." This article will take you deeper into understanding this indispensable core equipment in the coal industry.
I. How Does a Jaw Crusher "Gnaw" at Large Pieces of Coal?
The working principle of a jaw crusher simulates the chewing action of an animal. Its main working components are two jaw plates:
1. Fixed Jaw Plate: Like a sturdy incisor, it is vertically fixed to the frame.
2. Movable Jaw Plate: Positioned at an angle, it forms a "V"-shaped crushing chamber with the fixed jaw plate. Driven by an eccentric shaft, it periodically moves closer to and further away from the fixed jaw plate.
When large pieces of raw coal are fed into the feed inlet, the movable jaw plate squeezes forward, and the material is crushed by the enormous crushing force between the two jaw plates. When the movable jaw plate retracts, the material, now smaller than the discharge opening, is discharged from the bottom by its own gravity. This cycle repeats continuously, achieving continuous and efficient crushing operations.
II. Why is a jaw crusher the preferred choice for coal crushing?
1. Powerful crushing capacity: Suitable for various materials with a compressive strength not exceeding 320MPa, more than capable of handling hard coal gangue and large chunks of raw coal.
2. Simple structure and easy maintenance: The overall structure is simple, the core components are robust and durable, and daily maintenance and replacement costs for wear parts (such as jaw plates) are low, with simple operation.
3. Stable operation and strong adaptability: It has low requirements for the moisture content and gangue content of materials, maintaining stable operation even under harsh working conditions, with a low failure rate.
4. High return on investment: The equipment price is relatively affordable, and the operating cost is low, making it an ideal choice for coal companies seeking high cost-effectiveness.
III. How to choose the right coal jaw crusher model?
Choosing the right model is key to ensuring production efficiency. You need to focus on the following parameters:
• Feed size: What is the maximum size of the coal you need to crush?
• Discharge Particle Size: What is the desired particle size of the crushed coal? (Controlled by adjusting the discharge port at the bottom of the jaw plate)
• Processing Capacity (Output): How many tons of coal do you need to process per hour or per day?
• Motor Power: Ensure the on-site power supply can meet the equipment's requirements.
We recommend informing our technical engineers of your specific needs so we can recommend the most suitable model, avoiding issues of over-engineering or insufficient capacity.
A high-efficiency, reliable jaw crusher is the "pioneer" of a coal production line, its performance directly affecting the smoothness of subsequent processes and the quality of the final product. Choosing a high-quality jaw crusher lays a solid foundation for your entire coal processing business.
