So I bought this from eBay of all places and had it shipped in from the factory in China. The crushing size is about 14X8 but that is going to depend on what you are crushing and how big the opening is set at the bottom. The machine is powered by a one cylinder Chinese diesel motor that has proven to be reliable so far. Their air cleaner is a joke so plan on rigging your own. Also it is water cooled but lacks a cap (or even a cover) and they expect you to drain the water out each time when you are done. Because I think it is only a matter of time before i forgot and froze the thing I run antifreeze in it. Because the coolant tank is a big open hole rock dust settles in there, I will have to come up with a solution for that. I ran the thing with loose belts for a while to insure it would stall out without damage if anything went wrong but once I got comfortable with it those were tightened back up.
Besides some loose jaw clamps that had to be reground the only serious issue was the keyway mismatch between the crankshaft and pulleys. Two different sizes. Luckily we noticed the pulleys were moving on the shaft and cut some custom keyways because that would have wrecked both the shaft and the pulleys in very short order. Not a hard fix but not one that most people would think to check until too late. I would be sure to check that on any machine from now on. Beyond that I have fabricated a crappy little rock cage to keep stones from crashing down on the motor and converted it to grease from oil because of the mess it was making.
Importing means dealing with a bunch of paperwork and customs crap where you are always waiting on people in another country. Each time I contacted them there was yet another little fee tacked on. Sounds and feels like a racket but it is apparently what to expect unless you are a big importer. Just budget another 20-30% shipping on top of whatever they quote you. We picked our crusher up from the port itself in Washington. If you are going to have it drop-shipped that will also be extra.
So far I haven't been overly impressed with the build quality but it isn't far from what I expected. The jaws are reversible (supposed to be anyway) and I am sure I will be able to flip them but since they are not uniform it will take some modification. I have no idea where to get replacements if they ever wear out but so far that hasn't been and issue. The rock we are crushing is crazy hard so I expect less durability than those in other environments.
When I started this I was originally going to buy from Baker Mountain Mining and Metals. They have a number of videos here and buying from them would give you some peace of mind when it comes to parts and inspections. Sometimes I still wish I had just paid and bought from them even myself, but as a cheap bastard... I didn't. Anyway be sure to check them out first. They seemed like knowledgeable guys. Link below.
