The purpose of this program is to demonstrate the feasibility and practicality of noise control for secondary and Tertiary crushers in surface noncoal mining plants and mills. Two noise enclosures were designed and evaluated for 7-foot-diameter secondary and Tertiary crushers installed at the Jackson County Iron Company in Black River Falls, Wisconsin. The first enclosure had a circular shape following closely that of the crusher and was built up entirely of quick- release panels that can be handled by the crusher operator alone. The second enclosure was octogonal in shape and can be rapidly removed, partially or totally, using an overhead crane. Both enclosures satisfy the noise reduction objectives and permit daily and long-term maintenance of the crushers.
