Ore jaw crusher is a widely used equipment in mining, metallurgy and building materials industries. Its design goal is to crush large pieces of ore into small particles suitable for subsequent processing through the reciprocating motion of the fixed jaw plate and the movable jaw plate. Jaw crusher occupies an important position in the field of ore processing with its simple structure, convenient operation and high production capacity.

Ore Jaw Crusher Design Principle

The design of ore jaw crusher should follow the following basic principles:

High efficiency: The design of the crusher should ensure sufficient crushing efficiency and be able to handle a large amount of ore materials.

Durability: Since ore crushing often involves materials with higher hardness, each component of the crusher must have wear resistance and high strength to ensure long-term stable operation.

Safety: The safety of the equipment needs to be considered during design to ensure the safety of the operator and prevent equipment overload and failure.

Environmental protection: With the increasingly stringent environmental regulations, noise and dust pollution should be reduced as much as possible during design.

Ore Jaw Crusher All Parts Name/Jaw Crusher Components

Ore jaw crusher usually consists of the following main parts:

Frame: The frame that supports the entire crusher, usually made of high-strength steel, which can withstand the huge pressure generated when the equipment is running.

Jaw plate: It is divided into fixed jaw plate and movable jaw plate, which is responsible for clamping and crushing the ore. Its shape, material and installation method need to be considered during design to ensure efficient crushing.

Flywheel: The jaw plate is driven to reciprocate by rotating the flywheel. The design of the flywheel needs to balance the operation of the equipment to prevent excessive vibration.

Transmission system: It includes parts such as motors, belts and gears to ensure that the jaw crusher can operate stably and provide sufficient power.

Ore Jaw Crusher Design

Crushing chamber type:The deep chamber type is suitable for the crushing of large pieces of materials, with a larger feed port and a longer crushing path, suitable for coarse crushing. The shallow chamber type is suitable for the crushing of medium pieces of materials, with a shorter crushing path, suitable for medium and fine crushing.

Jaw plate shape:The straight jaw plate is suitable for coarse crushing, with a larger crushing force and higher crushing efficiency. The curved jaw plate is suitable for medium and fine crushing, with better material guidance and uniform crushing effect.

Discharge port design:The adjustable discharge port can control the discharge particle size by adjusting the size of the discharge port to meet different production needs. The fixed discharge port is suitable for production with specific particle size requirements, simple to operate, but less flexible.

Cavity shape ratio:A reasonable length-to-width ratio can improve the crushing efficiency of the material. Generally, the recommended length-to-width ratio is 1.5:1 to 2:1. Reasonable aspect ratio can reduce material accumulation and improve crushing effect. Generally, the recommended aspect ratio is 1.2:1 to 1.5:1.

Material flow path:The design should ensure that the material flows smoothly in the crushing chamber to reduce blockage and stagnation. Through reasonable feeding device and crushing chamber design, ensure uniform distribution of materials and improve the crushing efficiency of ore jaw crusher.

Wear resistance: Choose high wear-resistant materials to make jaw plates, such as high manganese steel, chrome-molybdenum alloy steel, etc., to extend the service life of jaw plates. Surface hardening treatment is performed on the jaw plates to improve their wear resistance and impact resistance.

Conclusion
The ore jaw crusher design should not only ensure that the equipment has efficient crushing capacity, but also consider its safety, durability and environmental protection. When designing, each component should be reasonably configured according to the characteristics of the ore and production needs. Through careful design, the ore jaw crusher can provide stable and efficient services in mining production.
