Reclaiming Operation Vs Machine Operator

-


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 operation started from the mid of the stockpile. The operator has started the reclaiming operation from the mid of the stockpile by lowering the boom to the stockpile.

This (reverse/middle cut) reclaiming operation is NOT ALLOWED since,
1.   The stockpile to be reclaimed has to be in front of the operator’s eye sight and not at the bottom of the operator cabin. In this case the stockpile is at the bottom hence the operator shall not get proper view of the stockpile.
2. While lowering the boom for reclaiming the next lower bench, there is a chance for the boom to collide with the top of the stockpile. This may disturb the stability of the machine and there are chances that the machine may derail.
3. Since the reclaiming operation has been started from the mid of the stockpile, in case of any failure in the machine it is impossible to take the maintenance crane near the machine since the machine is at the mid of the stockpile and both the sides are covered with the stacked material. Hence to create an approach to the machine, stockpile at one side to be cleared with the help of dozer or pay unloader which is a tedious operation.


TO CONCLUDE, IT IS IMPORTANT TO EDUCATE THE MACHINE OPERATORS REGULARLY ABOUT THE OPERATION OF THE MACHINE AND THE IMPACT IN CASE OF ANY FAILURE IN THE MACHINE.

Stockpile configuration

  To run any plant continuously, the basic requirement is the continuous supply of raw material. For example, to run a Thermal power-plant  or Steel plant or an Alumina plant, continuous supply of the raw materials viz., coal / iron ore / bauxite / limestone is required. Unfortunately, it is difficult to guarantee the continuous supply of raw material due to various factors viz., availability of raw material, transporting the raw material (by ship, wagon etc.,) or force majeure. Hence the solution is to store more than the required amount of these required raw materials in the plant itself. ‘Google’ defines stockpile as, ‘a large accumulated stock of goods or materials, especially one held in reserve for use at a time of shortage or other emergency’. Why the raw materials to be stacked and not dumped? It is because of the following limitations, ·        availability of space ·        quantity of material to be stored ·        equipment* used ·         p

Trapezoidal stockpile Vs Trapezoidal stockpile

Trapezoidal stockpile can be formed in the following two methods, 1.    Without compensating the travel length of the machine. 2.    By compensating the travel length of the machine. Each method has its own advantage and disadvantage. Before comparing the advantages and disadvantages, let us discuss how a trapezoidal stockpile is formed. Without compensating the travel length of the machine: The above figure shows a trapezoidal stockpile formed without compensating the travel length of the machine. By compensating the travel length of the machine: The above figure shows a trapezoidal stockpile formed by  compensating  the travel length of the machine. Travel length compensation: To understand travel length compensation, first let us discuss how a triangular stockpile is formed with the help of a stacking mode drawing. (Stacking mode drawing: Is the drawing which defines the slewing angle, luffing angle and the travel position of the stack

Consistency is an important and inevitable factor in any process plant. To meet a consistent quality output of the product (for example steel or cement) the raw material shall be fed continuously for processing in the required ratio. Consider a case in which the raw materials are stored in the stockyard in number of layers and during reclaiming if the consistency in blending is disturbed after sometime of reclaiming. The result will be change in product quality. Case study: Form a stockpile of 40m (Width) x 12m (Height) x 250m (Length) with 6 layers and discuss the consistency (mixture of all 6 layers of material) during reclaiming operation. Machines used for stacking & reclaiming, Stacker       - Luffing Stacker or Twin Boom Stacker Reclaimer   - Bridge Scrapper Reclaimer or Barrel Reclaimer or Wheel on Bridge Reclaimer (Note: above mentioned reclaimers are with harrow arrangement) STOCKPILE: Below sketch shows a stockpile of 40m x 12m x 250m (rep
