How much material can the K-JC 503 crush per hour?
This unit will crush up to 34 tons per hour, however your output production will depend on specific material types, material sizes, desired output sizes, and the overall setup and operation of the machine.
Many variables can affect the actual production rate, including:
- Material Type: Different materials have different densities and properties, which can impact processing efficiency.
- Material Size: The size of the input material can affect the machine’s performance. Larger pieces may require more time to process.
- Desired Output Size: The finer the output size, the longer it can take to process the material.
- Operation Setup: Proper setup and maintenance of the machine are crucial for achieving optimal performance.
What does “up to tons per hour” really mean?
The “up to” production rating refers to the maximum potential output a machine can achieve under ideal conditions—this includes consistent feed material (size, hardness, and moisture), skilled operator use, proper setup, and minimal downtime. For example, clean concrete with no rebar, fed at a steady rate in optimal weather, will produce higher output than mixed, wet, or irregular materials. Every job site is different, which is why we emphasize that this is not a guaranteed or average output, but a best-case scenario metric. If you’re unsure what output to expect for your application, we’re always happy to review your material and help you model realistic results.
What size can the K-JC 503 crush down to?
This compact mobile crusher can crush material that is roughly 12″ to 10″ minus, down to a range of sizes from 3/4″ to 3-1/4″. Your output size can be hydraulically adjusted using the remote controller to any size within this range.
What type and size of materials can the K-JC 503 crusher process?
This compact mobile crusher works best with hard, brittle materials like concrete, softer stone, brick, cold asphalt, and other natural rocks. The jaw inlet opening is 19″ x 12″ so we recommend pre-processing material down to roughly 10″ minus.
