Coal Stacking, Blending & Reclaiming
Dear Mr. Riaan,
Please clarify the following:
1.What is your mode of unloading method. Is it by wagon tippler with SAC.
2. What is the storage method.
3.What is the layout.
Please give some basic information to get reply.

Re: Coal Stacking, Blending And Reclaiming
Dear Mr. Riaan,
The information mentioned by you is not sufficient to understand your exact requirements. Firstly you are saying you have to handle 9 types of coal for unloading and reloading. It is improbable that at a time you will be receiving 9 types of coal and at a time you have to dispatch 9 types of coal. In all probability you will be receiving only one type of coal at a time and may be dispatching coal at one or two points.
Suppose you have to dispatch only blended coal. In this case, you have to put incoming coal into blending yard. You have to also decide how many categories of coal you intend to blend. Suppose you intend to blend 4 categories of coal then, you have to select the size of the blending yard such that before the blended stockpile full capacity is reached, you must receive the designated 4 categories of coal in appropriate quantity. This means the system and modality of blending is greatly influenced by frequency and duration of arrival of various types of coal and frequency and duration of dispatch of the coal. The formulation of this appropriate system is very crucial for easy management and operation of the entire system afterwards.
As for the degree of homogenization and blending efficiency is concerned, the equipment appropriate to this requirement can be selected. The type of equipment will depend upon the capacity and degree of homogenization or blending.
In short, the efficiency (i.e. efficiency in relation to qualitative as well as quantitative output) will be consequence of right choice of the overall system and individual equipment. How so good individual equipment but arranged improperly will not give desired result.
There are various methods for blending, depending upon capacity and other points. It can comprise of regular stacker reclaimer etc. or in certain situation it can be just mixing of coal from different storage points and create the blended coal. For example, if there is continuous incoming coal-A by one conveyor and coal-B by another conveyor, people are also creating blended coal just by discharging both the conveyors in to a common chute.
This is a lengthy and serious subject and further elaboration is difficult in this forum. In case you need more guidance, you can communicate by email.

Coal Stacking, Blending and Reclaiming
Can anyone help me with the following problem/Project we has to undergo in ISCOR South Africa.
We are currently Unloading and Loading 9 different commodities of coal at ISCOR South Africa, because of different properties we are looking for in all the caol.
The handling of 9 commodities is a logistical nightmare. It takes us about 25 minutes to change between the different commodities (Because of the conveyer belt length, the commodities must first loaded off before starting with a new commodity). We want to blend the different coal on a storage area (Outside in the open) and then only reclaim one "Commodity"
Can somebody help me with suggestions and pitfalls IO must lookout for
Any help will be of utmost appresiation ■
