The size of a jaw crusher directly impacts its capacity for a few key reasons:
Feed Opening Dimensions: The size of the feed opening dictates the maximum size of material that the crusher can accept. A larger feed opening allows larger-sized material to be processed, which can lead to higher capacity as more material can be fed into the crusher at once.
Volume of the Crushing Chamber: The overall size of the jaw crusher, including the volume of its crushing chamber, affects how much material can be processed at one time. A larger chamber size typically means that more material can be held and crushed in each cycle, enhancing throughput.
Discharge Setting: The size setting of the discharge opening also plays a role. If the discharge opening is larger, more material can exit the crusher, allowing for a higher throughput. Conversely, a smaller setting results in more fine material, which may slow down the feeding of larger material.
Stroke Length and Speed: Larger jaw crushers with longer throw and faster speed can generate more power and offer higher capacity by pushing more material through the crushing chamber during each cycle.
Overall Crusher Design and Construction: Features such as the angle between the jaws, the design of the toggle plate, and the crushability of the material being processed all contribute to the overall capability and efficiency of the crusher, impacting capacity.
In summary, larger jaw crushers generally have higher capacity because they can handle larger loads and process more material with each stroke, assuming other operational conditions are favorable. However, it's important to balance size with the requirements of particular applications, material characteristics, and operational considerations.
