BASICS IN STACKER RECLAIMER

In the previous article (titled ‘Reclaim Mode Drawing and Case Study on YouTube Video’), a question has been asked along with a photograph. For your convenience the same is mentioned below: Although it is possible for the operator to reclaim (in manual mode) the material from the stockyard as shown in the below photo, IT IS NOT ALLOWED to do so. ‘WHY IT IS NOT ALLOWED’? It has been explained in the previous article that the reclaim operation has to be started only from the EDGE of the stockpile. Whereas in the above photo, the reclaim operation has been started from the mid of the stockpile by the operator. That’s why instead of a CONCAVE CURVE, we see a CONVEX CURVE on the stockpile. For more clarity refer the below 3D models. 1.    Stockpile 2. Forward cut reclaiming operation (GENERAL PRACTICE) in which the reclaiming operation started from the edge of the stockpile. 3. Reverse/Middle cut reclaiming operation (NOT ALLOWED) in which the reclaiming opera

I’ve seen an animation in the YouTube on reclaiming operation by a bucket wheel reclaimer machine. The animation is very good, but the reclaimed portion of the stockpile is not represented correctly in the animation. Before looking into this, I just want to explain THE RECLAIM MODE DRAWING ie., HOW A BUCKET WHEEL STACKER CUM RECLAIMER RECLAIMS THE STACKED MATERIAL FROM THE STOCKPILE. This will make you to understand the wrong representation of the reclaimed stockpile portion in that animation. (It is not ethical to give the YouTube video/link in this blog, since the YouTube video contains the company logo also. For your reference, I’ve just shown the screen shot from the video WITHOUT the company logo) Consider the stockpile (& other parameters) we have discussed in one of the previous articles (titled “Trapezoidal stockpile Vs Trapezoidal stockpile”).
