No, I currently do not have a crusher, but the last one I used was a leased Extec c-10 jaw crusher (I only needed it for one job). It was sufficient for the job but if I were to buy one I would probably go with a larger unit (just for flexibility of throughput).

In a related note, I have recently signed as an independent rep for MetalTech Systems, a General Kinematics/Sherbrooke OEM distributor. We manufacture custom material handling systems, so if you are looking for a site oriented c&d screening/recycling system, I would like to be able to help.
You can pm me if you want and I will send you some contact info.
