As one of leaders of rate analysis of crusher plant industry, SBM always seeks innovation & excellence.
In any crushing operation, the raw material flow rate and the reduction ratio (ratio of feed size to product size) have obvious influences on the wear of crushing equipment. However, the hardness and fracture toughness of the rocks being crushed are unavoidable parameters in allowing for the wear of crushing plant.

26/02/2016· The term "primary crusher," by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusher for this service are much the same, regardless of how many

The plant is fed with blasted rock defined as granite, with a particle size distribution denoted medium blasted rock, see the curve in Figure 1. The hauling capacity of the available trucks limits the feed rate to 270 tonnes per hour. Two different optimisations were done to demonstrate the influence of particle shape on the operation.

the oversize (+150 mm) advancing to the primary jaw crusher, which operates in open circuit. The jaw crusher opening is 1500 mm x feed 1070 mm and the installed power is 200 kW, operating at a closed side setting of 135 mm. The jaw crusher discharge product and the scalping screen undersize produce a mill feed that is 80% passing135

Because when the crusher runs at high speed, all the power consumed by the friction will be converted into heat, and the temperature of the parts will increase; if the lubrication works properly, the friction surface will absorb the heat and dissipate under the action of the lubricant, thereby reducing the machine The surface temperature, which reduces the maintenance rate of the jaw crusher

Sampling/Pilot Plant Crushers are ideal for clients who have applications that require relatively low feed rates but still expect the durability and robust design usually associated with larger crushing machines. Using a significantly oversized crusher to handle the crushing requirements in either type of scaled-down material handling system is not an effective option for a number of reasons

The coal crusher generates large vibrations when crushing coal blocks, which can affect the equipment itself, as well as the safety of the structure. In order to study the dynamic characteristics of coal crusher, a finite element model of the coal crusher chamber in the Shangluo power plant was built by using ABAQUS. Firstly, modal and harmonic response analyses were conducted, and the

the crusher. Following the analysis above, it is obvious that for the optimization of the capacity of the crushing circuit one has to take into consideration the breakage rate of the material as a function of the breakage intensity, the power of the crusher motor and the height lose in the circuit. In a real plant one should also take into consideration the energy consumed for the operation of
