BALDWIN LIMA HAMILTON
Posted by GUSTAVO from CHULA VISTA, CA, US on March 27, 2009
WOULD YOU KNOW OF ANYBODY THAT STILL CARRIES PARTS,
JAWS, TOGGLES, ETC. FOR BALDWIN LIMA HAMILTON CRUSHERS??
This could either be an old Eagle or Austin Western Jaw crusher. We may have parts for this depending upon what size & model crusher it is. Physical dimensions of the stationary & movable jaws along with photographs would get us closer to determining if we had anything we can supply. If you wish, follow up with me directly at steve_dz@columbiasteel.com
Cylinder End Bushing
Posted by Brett from Randolph, MN, US on March 19, 2009
I need to make replacement bushings for my customers cyl. rod. He gave me a worn out one for a sample. I had it analyzed and was told it has: C - 1.10, Mn - 13.0, Si - 0.55, P - 0.030, S - 0.010.
None of my regular suppliers seem to know what grade of material this is.
Can you help me?
Brett
The following answer was supplied by David Havel, Chief Metallurgist at Columbia Steel:
The material in question is a grade of Hadfields Manganese Steel. ASTM classifies this material as A128 grade A or grade B-2, both would provide for the measured chemistry. This type of material is used for bushings due to its anti-friction and work hardening properties. Columbia Steel makes bushings in this alloy as well as a few other suppliers. Most bushings of this material are castings, but a few suppliers sell forged bushings in this type of material.
Type of Crusher Best for Recycling
Posted by paul from lansing, MI, US on March 13, 2009
What type/model crusher would you recommend for recycling 4″–6″ thick slab concrete broken into approx. 2′x2′ pcs. down to 3/4–1″ aggregate? I would like tranport the crusher to the jobsite, moving 1–3 times per week and reuse or sell the crushed concrete.
Thanks, Paul
There are a broad range of crushers available for the recycle industry. They range from vertical to horizontal impactors to special wide jaw crushers. It appears that the general consensus is to use horizontal impactors. Most of the large crusher manufacturers offer one or more sizes to choose from. I would contact one of these manufactures for your needs.
TOGGLE BEARING
Posted by John from Langeloth, PA, US on March 12, 2009
i AM LOOKING FOR 2 PCS. TOGGLE BEARING #866 FOR BIRDSBORO SAMPLE CRUSHER, 12 X 16
Although we do not have anything listed for this size crusher, it does not imply that we cannot help out. We would need a sample casting or dimensional data in the form of a sketch or end tracing w/overall length to determine if we had anything close enough to offer or to make new drawings for quotation purposes. Feel free to contact me directly if this is the direction you'd like to pursue -- steve_dz@columbiasteel.com
