Abstract

The invention discloses a detection device of a static material layer thickness between dielectric spheres. The detection device comprises a support, guide rods are respectively fixed at the upper end of the support and the lower end of the support, a moving base is arranged on the guide rods, the moving base can slide along the guide rods in a left-and-right mode, a first ejecting rod is fixedly arranged at one end of the support, a first ruler rod is fixedly arranged on the first ejecting rod, one end of a screw rod is connected with a hand wheel in a rotating mode, the other end of the screw rod is connected with the moving base in a threaded mode, the hand wheel pushes the screw rod to rotate so as to drive the moving base to move along the guide rods in a left-and-right mode, the moving base is connected with one end of a force measuring device, the other end of the force measuring device is connected with a second ejecting rod, a second ruler rod is fixedly arranged on the second ejecting rod, and a V-shaped guide plate is arranged between the two guide rods which are arranged between the first ejecting rod and the second ejecting rod. According to the detection device of the static material layer thickness between the dielectric spheres, the static thickness of the squeezed material layer between the dielectric spheres can be effectively measured through measurement of change of distance between the two ruler rods, and more accurate experiment data can be provided for ball milling process design.

Description

technical field [0001] The invention relates to a device for detecting the thickness of a static material layer between dielectric balls. Background technique [0002] Spherical medium is the most widely used medium in the grinding production of ball mills. The crushing of particles is mainly realized by the collision and extrusion between two medium balls. However, due to the lack of an accurate description of the collision and extrusion process between the medium spheres, it is often simply considered that there is only a single broken particle between the medium spheres, or the empirical method is used to estimate the collision extrusion force required for particle crushing, which is different from the actual When the particles between the medium balls are collided and crushed, they exist in the form of material layers with large discrepancies, resulting in inaccurate ball milling process parameters and low energy utilization. Therefore, it is necessary to design the rel...
