Bulk material conveying system, mobile single roll crusher and control method thereof

Abstract

The invention discloses a control method and system of a mobile single-roll crusher. The mobile single-roll crusher comprises a crushing part and a walking part, wherein the crushing part comprises a crushing pin roll. The control method comprises the following steps: step 610. detecting the operating speed of the crushing pin roll of the crushing part, judging whether the operating speed is less than the stall reference speed, if so, counting the hold time, and if no, further detecting the operating speed of the crushing pin roll; step 620. judging whether the hold time is more than the first setting time, if so, executing the step 630, and if no, resetting the hold time; step 630. controlling the crushing part of the mobile single-roll crusher to store energy. The control method has the beneficial effects that through the step of storing energy, the crushing part can carry out crushing again after the crushing kinetic energy of the crushing part recovers to a certain or the maximum state, so that the overload probability is reduced, thus improving the crushing efficiency of the crusher. The invention also provides the mobile single-roll crusher applying the control method or the control system and a bulk material conveying 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.
