The ultimate goal in optimizing aggregates production is to increase the number of tons produced per man-hour. And crusher capacity is probably the first line of offense in reaching production goals. The coarse aggregate crusher is a modern, high production secondary cone crusher specifically designed for large, extra coarse feed material. The cone serves the mining and aggregate industries with reliable high performance.
Coarse aggregate crusher
Fitting into secondary crushing circuits that used to require larger crushers, Zenith coarse aggregate crusher in Tanzania can reduce the capital requirements for plant expansion projects. Accepting extra coarse feed, the machine allows primary crushers to operate at larger settings and at greater capacities, providing opportunities to increase plant production with minimum investment.
An evolution from the productive cone crusher, it incorporates new internal components that significantly increase the feed opening while maintaining optimum crushing characteristics. The crushing plant also incorporates modern features identical to those in design.
The horizontal-shaft impact crusher with two shafts typically reduces materials before a subsequent process stage, usually further size reduction. Common applications are reducing up to 10-inch chunks or lumps of material with a Mohs hardness of up to 3, including caked powder and filter press cake, resin, wax, ammonium nitrate, pigments, and other materials. By applying shearing and compression forces, the crusher typically reduces the material to 0.5-inch or larger particles.
Material is gravity-fed between the shafts, which rotate at low speeds up to about 120 rpm. As the material is drawn down between the rotating shafts, the tools shear and compress the particles. The reduced particles discharge by gravity through an outlet screen below the shafts, which retains oversize particles to control the final product’s particle size.
The horizontal-shaft impact crusher can handle large throughputs. For instance, the relatively small unit, with a feed inlet of 12 by 18 inches, can reduce 8 inch resin blocks to 2-inch particles at 9,000 lb/h, 4inch wax blocks to 0.75-inch particles at 5,000 lb/h, or 3- to 4- inch pigment blocks to 0.5-inch particles at 10,000 lb/h. These crushers typically come in models ranging from 0.5 to 10 horsepower.
