A kind of multifunctional roller crushing experimental device and experimental method

Abstract

The invention discloses a multifunctional roller type breakup experiment device and an experiment method thereof. The device comprises a support and a top beam. Elevating platforms are arranged below the top beam. The elevating platforms are fixed on the top beam via fixing blocks, plug pins and hydraulic oil cylinders. The two sides of the elevating platforms are provided with an elevating frame. A breakup platform is arranged below the elevating platforms. The breakup platform is fixed on a revolving wheel which is arranged below the breakup platform. The revolving wheel is fixed on a moving platform which is arranged below the revolving wheel. The revolving wheel is connected with a step-less speed regulating motor via transmission shaft. The two sides of the bottom part of the moving platform are provided with a track frame. The moving platform is connected with the motor via a transmission mechanism. A revolving roller is arranged below the elevating platforms. A data acquisition system is arranged between the elevating platforms and the revolving roller. The limitation that a press machine and a ball grinder are adopted for operation respectively by a rolling experiment and static pressure and dynamic pressure breakup test experiments and a rolling breakup test experiment are not performed on one set of experiment equipment is solved so that optimization experiment research on all breakup parameters can be conveniently realized.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a multifunctional roller crushing experimental device and method. Background technique [0002] In the mineral processing plant, the crushing process is a unit operation with high investment and high energy consumption. Crushing equipment accounts for more than 50% of all equipment in the mineral processing plant, and energy consumption accounts for 60%-70% of the total energy consumption of the mineral processing plant. In the field of crushing, saving energy and improving comprehensive economic production efficiency are the fundamental goals of grinding. The high-pressure roller mill is a new high-efficiency and energy-saving material layer crushing process. Its appearance is a new level of crushing technology development, and it adds new content to the field of crushing theory. At present, among the experimental devices based on ore crushing research, most of the predecessors used pr...

Problems solved by technology

[0003] Furthermore, due to the complexity of crushing engineering and the limitations of research methods, some conclusions are still in the stage of experience summary

For example, although the crushing effect of material layer crushing, the direct relationship between crushing probability and crushing conditions have been studied at home and abroad, a lot of crushing has been done, but the research on the relationship and optimization of various crushing parameters is not deep enough.

These have led to many problems in the crushing mechanism of the material bed of the high pressure roller mill to the application, which needs to be further studied
