Abstract

The invention relates to the technical field of rock milling and crushing, in particular to a method for establishing a rock milling force model and a rock milling test device. The method comprises the following steps of: carrying out an intrusion test on a rock sample block, and determining the intrusion strength of the rock, and based on the intrusion strength of the rock, determining a millingforce calculation model of the rock. The milling force is no longer studied by directly carrying out a milling test; the rock milling force calculation model is determined on the basis of the rock intrusion test, the test process is simple, the manpower and material resource cost can be saved, the obtained milling force calculation model provides a theoretical basis for rock milling force research, and the rock milling force research process can be effectively simplified.

Description

technical field [0001] The invention relates to the technical field of rock milling and crushing, in particular to a method for establishing a rock milling force model and a rock milling test device. Background technique [0002] Rock milling and crushing is a complex process in which rock-breaking tools such as picks interact with rock. The rock-breaking tool installed on the rotor rotates and squeezes the rock. When the squeezing force exceeds the limit of the physical and mechanical properties of the rock, the rock breaks and breaks. [0003] The study of milling force has certain theoretical guiding significance for the customized design of rock breaking tools under different operating conditions, the design of rotor installation and arrangement, and the matching design of milling torque and propulsion force of the whole machine. [0004] In the related art, there is no directly usable milling force model, and the milling force can only be studied directly through milli...
