Jaw crusher is generally used as the primary crusher in the crushing circuit and connects to the ore feeding machine. In the early years, common used plate feeder, but now, the vibrating feeder is more popular. Practice has proved that the vibrating feeder has advantages of low power consumption, strong transportation capacity, low failure rate The particle-size-distribution characteristic curve of ore crushing products is always “sandwiched” between the curves of pyrrhotite, sphalerite, and quartz within the same feed-size range.

احصل على السعرNumerical Study on Crushing Law of Iron Ore under
Ore crushing is one of the most important steps in mine engineering, and numerical simulation is a useful way to predict the crushing effect under impact load. Based on continuum discontinuum element method (CDEM), by introducing the linear elastic constitutive law into the element and the cohesive model into the virtual interface, the Ore medium crushing is a process of crushing ore blocks with a feeding particle size of 125–400 mm to 50–100 mm. The maximum crushing ratio of medium crushing is about four. The force in the process of ore crushing is mainly crushing and impacting. The main equipment suitable for medium crushing operations is a jaw crusher, Ore Crushing SpringerLink

Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone crushers.3.

This study reports on the design optimisation of the swinging jaw crusher plate. Jaw crusher machines are used in the mining and construction industry for crushing rocks and mineral ores to the appropriate sizes for direct application or further processing. During the crushing process, large and non-evenly distributed impact forces occur, crushing to fully open the ore mineral in one crushing machine. At each stage, crushers and mills of various types are used, depending on the size of the material [2, 3]. The differences in the stage of crushing and grinding depending on the nominal size of the starting material and the final product are shown in Table 1.
