The design of the hammer plays a crucial role in its performance. Its shape and material composition determine how effectively it can handle different types of materials. For instance, a hammer made from high-strength alloys can withstand the impact of hard rocks, ensuring durability and efficiency. The movement of the jaw is powered by a motor, which drives the eccentric shaft. This shaft converts rotational energy into the linear motion required for crushing.

Crushing Process and Material Breakdown

The crushing process begins when you feed material into the jaw crusher. The material enters the crushing chamber, where the moving jaw compresses it against the fixed jaw. This action reduces the size of the material, making it easier to handle or process further. The hammer's impact creates fractures in the material, breaking it into smaller pieces.

The efficiency of this process depends on several factors, including the material's hardness, size, and the design of the crusher. For example, softer materials like limestone break down more easily than harder ones like granite. The energy used during crushing is distributed across various components. A significant portion of this energy is released as elastic strain energy, which contributes to the creation of new surface areas.
