Profile: Mulzer Crushed Stone, Inc. delivers thousands of tons of state-approved crushed stone for driveways to highways construction projects. We also produce derrick stone, rip-rap, sand, gravel & high calcium limestone for power plant desulfurization equipment. We work with companies & government agencies on custom products. Our quarries supply crushed limestone that is as large as a car, or as small as dust. River & pit dredges allow us to provide most sand and gravel products. We have identified ledges of high calcium limestone that makes scrubber stone which is used by power plants to remove sulfur-dioxide produced by burning coal.
