[QUOTE="jethro, post: 583475, member: 1297"] Hey Ruddy I have made a small jaw crusher as well as a Impact mill. So heres a few observations/ tips. If you want to Hardface something you need to consider whether it will be and abrasive wea,r like the cutting edge on a dozer blade or wear caused by high speed impact with hard objects like in impact mills. Many of the welding consumable companies list their MMA rods and there ideal application on their websites. 16tc's are good for a cushion layer between the base and the hardface. Ive been using CIG Coblarc electrodes bought by the stick from Southern cross Welding supplies, as I dont need a whole Box. I cant remember the exact Code but they were a self air hardening Martenistic Rod. They work very well on both abrasive and impact type wear surfaces. If your jaw crusher is stalling on the belts you may need to add a flywheel to the concentric end of the eccentric shaft to give it some inertia. The shaft should be turning at between 60 and 100 rpm, also the larger the pulley contact length on the belt the more grip you will have for the same amount of belt tension. :Y: :Y: [/QUOTE]
