Embodiment Construction

[0043] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings: figure 2 , 3 Shown is a rock crushing simulation test device. The simulation test device includes a horizontal test platform. One end of the test platform is provided with a test chamber 3 containing a rock test piece inside. The sliding piston 4 is used to place, load and recover the rock specimen. The test chamber 3 and piston 4 simulate the hardened metal surface in actual engineering. A test rod 7 is set on the outer side of the piston circular plane and on the central axis of the piston, which is airtightly fitted with the piston 4. A compression strain gauge is pasted at 1 / 2 of the length of the test rod 7, and the compression strain gauge is connected to the dynamic strain gauge 8. The dynamic strain gauge 8 is connected to the oscilloscope 6; at the other end of the test rod, at a distance of 10cm~15cm from the end of the tes...

Abstract

The invention relates to an experiment device for testing rock breakage and a method for calibrating impact speed and loss energy. The device mainly comprises a test piece chamber, an impact loading system and an experimental test system, wherein a multi-granule rock test piece is arranged in the test piece chamber; the impact loading system comprises a test pole, an emission bar, an emission sleeve and an air compression system; the experimental test system comprises a linear speed meter, a strain gauge, a dynamic strain gauge and an oscilloscope. The method for calibrating impact speed and loss energy comprises the steps of recording the impact speed of a piston by using the linear speed meter and the oscilloscope; respectively recording the time-variable signals of shock-loaded waves and reflected waves in the test pole by time using the dynamic strain gauge and the oscilloscope; calculating the collected data to obtain the energy loss in an experiment process. After the device andthe method are adopted, the relationship between rock breaking effect and energy consumption can be studied under the different loading rates by changing the air pressure. The simulation experiment device has the characteristics of being simple in structure, high in simulation authenticity and good in repeatability of a test process.

Description

Technical field [0001] The invention relates to an experimental device for testing rock crushing and a method for calibrating impact velocity and energy loss, and belongs to the technical field of rock crushing research and testing. Background technique [0002] Rock fragmentation is a very important part of the mining and metal smelting process. The process usually uses a pair of hardened ferroalloy surfaces to break large pieces of rock to obtain fine rock particles. According to statistics, the world produces more than 3 billion tons of various metal ores each year. These ores are usually crushed in a rock crusher before subsequent processing. Rock fragmentation is not only a subject of theoretical research, but also an important subject of practical application research in production. In practical engineering applications, rock crushability is usually used as a quantitative index to judge the ability of rock to resist mechanical crushing in the crushing process. It is the m...
