The majority of these rules are echoed below: 1. An underground mine is more economically served by a belt conveyor than railcars or trucks when the daily mine production exceeds 5,000 tons. (Source: Al Fernie) 2. As a rule, a belt conveyor operation is more economical than truck haulage if the conveying distance exceeds 1 km (3,280 ft.).
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...
