Material handling system, mobile single-roll crusher, control method and system thereof

Abstract

The invention discloses a control method and control system of a mobile single-roller crashing machine. The control method includes the step 410 of detecting the operation current of a traveling part, judging whether the operation current is larger than twice of a rotation-stop reference current or not, and if yes, timing the holding time; the step 420 of judging whether the holding time is longer than the second set time, and if yes, carrying out the step 430; the step 430 of controlling a crashing part of the mobile single-roller crashing machine to store energy; the step 440 of adding 1 to the energy storage frequency, judging whether the energy storage frequency is larger than the first set value, and if yes, carrying out the step 450; and the step 450 of giving a command to make the crashing part stop operating and make the traveling part stop operating or retreat to the standby station, and sending a crashing failure alarm. Through energy storage, the crashing work can be conducted when crashing kinetic energy restores to a certain extent or to the maximum extent, and thus the overloading probability is lowered and the crashing efficiency is improved. The invention further provides the mobile single-roller crashing machine with the control method or the control system applied, and a material processing system.

Description

technical field [0001] The present application relates to the technical field of crushing equipment control, in particular to a control method and control system for a mobile single-roll crusher. The mobile single-roller crusher can also be a grate (grate) crusher or a grate crusher, a traveling type cutting and dredging machine, etc. [0002] In addition, the present application also relates to a mobile single-roll crusher to which the above-mentioned control method of the mobile single-roll crusher or the control system of the mobile single-roll crusher is applied. In addition, the aforementioned mobile single-roll crusher control method and mobile single-roll crusher control system can be used in equipment for excavation or tunneling after adaptive adjustment. [0003] In addition, the present application also relates to the application of the above-mentioned control method of the mobile single-roll crusher, the control system of the mobile single-roll crusher, or the bulk...

AI Technical Summary

Problems solved by technology

After the crushing roller is "blocked", it may cause the crushing roller to stop rotating (at this time, the drive motor or motor is blocked), and the stopping of the crushing roller will cause it to be unable to crush the material on the grate, and the material cannot fall from the grate hole, resulting in The walking system of the mobile single-roll crusher is also blocked or the mobile single-roll crusher has a climbing phenomenon

If the "blocking rotation" does not cause the crushing roller to stop rotating but only the speed to drop, the crushing kinetic energy of the crushing roller will decrease, the crushing capacity will decrease, and the traveling system will be overloaded due to the blocked progress, which will also lead to a decrease in the working efficiency of the entire processing system; Of course, in this case, there is a higher probability that the speed of the crushing roller will be zero due to a vicious circle caused by the reduction of the crushing roller's speed due to "blocking" and the reduction of crushing capacity.
