THE ANALYSIS OF RESULTS OF EXPERIMENTAL RESEARCHES OF PROCESS OF LEVIGATING IN PEBBLE MILLS

The analysis of the received data at carrying out experimental issledovayony is the integral requirement for reliability definition analiyoticheskih the expressions presented in dissertational work, and also for an estimation of efficiency of process of levigating in a spherical drum-type mill.

By means of studying and tracing of these data exists vozmozhyonost precisely to estimate, as varied factors influence investigated process what of factors are the most significant and how much truly process has been described theoretically [1].

By means of a technique which has been described in chapter 3 section 3.6, were proyovedeny experimental researches of process of levigating on laboratory installation of a spherical drum-type mill, and also by means of numerical modeyolirovanija in program complex EDEM.

At performance of laboratory experiments on a natural model there was proyovedena a shooting by a high-speed videocamera in which result were poluyocheny time-lapse pictures of trajectories of movement of grinding bodies in the case of a drum head of a pebble mill. As a result of processing of numerical experiments trajectories of movement of grinding bodies ustanoyovivshegosja a levigating mode have been defined at any moment. Such approach has allowed to execute sravnitelyonyj the visual analysis of trajectories of movement of the grinding bodies, described in razdeyole 4.1.

At value of the varied factor x3=1,0число ledges is fractional (9,6), that is inadmissible. The decision to spend experimental isyosledovanija for 9 and 10 ledges was accepted, and then average values vyyohodnyh factors have been calculated.

The results of the experimental researches received on earlier opisanyonomu to the plan of experiments according to selected varied faktoyorami, are shown in table 4.1.
