    Dust suppression system for roads in rural Costa Rica

    Thanks for the insight oldestguy. Seems like a pretty clear win. Anyone have feedback on the international transport of solid Mag Chloride and later diluting it in water? Is there a target concentration? I'm sure google can yield answers, but I trust those with hands on experience the most...

    Dust suppression system for roads in rural Costa Rica

    Thanks for the help so far. Because there is lush vegetation and animal habitat, as well as landscaped properties with ornamental and fruit-providing trees and plants, anything that would degrade soil fertility is concerning. Would mag chloride definitely have this deleterious effect? Also...

    Dust suppression system for roads in rural Costa Rica

    Hello folks, Can you guys recommend a method/technology/company that offers a VERY economical solution to road dust? This is still the developing world and civil works are greatly underfunded. The rural areas do not pull the votes to merit investment in the eyes of the politicians. We have a...

    Tire cutting band saw?

    I'm not sure exactly how many tires need to be cut. I think it is more for examining internals of the tire construction, within a factory, rather than a recycling operation. Any other feedback or suggestions is welcome and appreciated. The ideal machine will be stationed in the workshop...

    Tire cutting band saw?

    Hi all, I'm looking for a US made band saw to cut through tires. Ideal saw will cut vertically, with tire braced vertically so as to cut it into two semicircles. I realize the blade will have to be durable to cut through tread grit and steel beads. Suggestions? Thank you!
