Run of Mine (ROM) materials are brought directly from blasting projects and crushed a primary crusher for the first round of crushing. At this point, the material receives its first reduction in size from its raw state. Primary crushing produces materials ranging from 50" to 20" on average. The two main types of primary crushers are: Jaw crushersAs this crusher is tried to be fully loaded all the time, mass flows of the primary crusher are have a fixed throw for all blast tests. In this state was obtained that the material loaded crusher mouth continuously. Mass flows of the primary crusher effecting energy consumption are directly related with average size distribution of the heap.Development of a model estimating energy consumption values of primary

For the sedimentary rocks (Siltstone) the specific crushing energy is approximately 1.26 kJ/kg. Tosun and Konak (2014) measured power consumption of jaw crusher during crushing of limestone rocksA primary crusher breaks up large pieces of rock or concrete from the blasting or excavation process and turns them into smaller, more manageable chunks. This is the first step in the crushing process. The smaller pieces can then either be pre-screened or fed directly into a secondary impact or cone crusher.What is a Primary Crusher? machinerypartner

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm.
