Which Crusher is the Best Primary Rock Breaker. Since the minimum dimension of the feed opening of a crusher determines the maximum size of lump that it can take, the choice of a primary breaker is dependent as much on the size of the feed as on the hourly tonnage. Thus a 15 in. by 24 in. jaw crusher would be suitable for a small mine hoisting ...

For coal, many times, rotary breakers are used as primary crushers and ring granulators are used as secondary crushers. Information on construction and working of various crushers is given in the following chapters. 8 Construction, Working and Maintenance of Crushers for Crushing Bulk Materials


Jaw crusher is used as primary crusher. It uses compressive force for breaking the material. This mechanical pressure is achieved by the two jaws of the crusher. Reduction ratio is usually 6:1. The jaw crusher is consisting of two vertical jaws installed to a V form, where the top of the jaws are further away from each other than the bottom.


Finally, coal was brought into furnace by primary gas, and the feeding rate was controlled at 0.3 g/min. Meanwhile, primary and secondary gases were mixed at the exit of injector for the complete combustion of coal. The conical breaker and fiberglass filter installed at the bottom of drop tube furnace were used for collecting ash particles.

Energy production – mainly the burning of fossil fuels – accounts for around three-quarters of global greenhouse gas emissions. Not only is energy production the largest driver of climate change, the burning of fossil fuels and biomass also comes at a large cost to human health: at least five million deaths are attributed to air pollution each year.

Primary fuels or primary energy sources are dense sources of primary energy found as natural resources.Primary fuels are fuels that are found in nature and can be extracted, captured, cleaned, or graded without any sort of energy conversion or transformation process. This means that all processing and collecting of the fuel is done before the fuel is converted into heat or …

Here, the coal was crushed, washed, and sorted according to size. The coal would come down a chute and along a moving belt. These breaker boys would work in what was called the picking room. Here, they would work hunched over for ten hours a day, six days a week, sorting the rock and slate from the coal with their bare hands.
