Adam.morris08 Posted August 6, 2015 Share Posted August 6, 2015 Hi I've sourced a 25kg bag of dolomite from a local pottery supplier. The tech sheet for it says that 87% of it will pass though a 75 micron seive. Will this be alright to put straight through a comco abrasive unit? Or will I need to screen it further? Cheers Adam Link to comment Share on other sites More sharing options...
ZiggieCie Posted August 6, 2015 Share Posted August 6, 2015 (edited) Congrats on your comco unit. here is there website. I had been through there before and they have a section on supplies, the products available and I thought the sizes of the material. Good luck with your TOY. http://www.comcoinc.com/products/microblaster/ Abrasives pdf http://www.comcoinc.com/wp-content/uploads/2012/06/MABMediaGuide.pdf Edited August 6, 2015 by ZiggieCie Link to comment Share on other sites More sharing options...
jpc Posted August 7, 2015 Share Posted August 7, 2015 I get my dolomite from pottery suppliers. It is called Dolowhite, and it works very well in both a Comco and a Swam Blaster. I use a size 40 soil sieve to screen my powder. Link to comment Share on other sites More sharing options...
