Building a Jaw Crusher: From Plates to Feeder

TLDRIn this video, I document the process of building a jaw crusher from scratch. I start by ordering the plates and side plates needed for the crusher, and then I figure out the best location for the crusher in my workshop. I drill holes, fasten the plates, and use a magnetic drill for precision. I also share the cost of the plates and the challenges I faced while welding. Finally, I build a feeder with a belt drive and demonstrate how it works. Overall, it was a challenging but rewarding project.

Key insights

🔧Building a jaw crusher from scratch requires careful planning and precise measuring.

⚙️The crusher needs to be properly aligned with the motor to ensure smooth operation.

💰The cost of the plates needed for the crusher can be quite high, but they are essential for its functionality.

⚒️Welding galvanized steel can be challenging and requires extra precautions.

👷‍♂️Using a plasma cutter can make cutting metal easier and more precise.

Q&A

How much did the plates for the crusher cost?

The fixed plate was 950 €, the removable plate was 1050 €, and the side plates cost a total of 600 €.

What challenges did you face while welding?

Welding galvanized steel was difficult and required extra care to avoid fumes and achieve strong welds.

How did you align the crusher with the motor?

I used a laser to ensure that the belts were aligned and that the crusher would run smoothly.

Can you explain the belt drive system for the feeder?

The belt drive uses multiple belts to transfer power from the motor to the feeder, providing controlled feeding of materials.

What precautions did you take when cutting metal with a plasma cutter?

I made sure to wear appropriate safety gear and followed safety guidelines to prevent accidents and protect myself from sparks and debris.
