| Life is about 20000 tons and Cost is Rs 80,000.00 So the Cost is per ton Rs 4.00 per Ton.
Wearing of the anvil depends upon the feed size. More wear for bigger feed, and less wear
for smaller feed size. Value is given for below 40 mm feed assorted. It may change with the
density of the stone, More density means more wearing. It may vary about 30% plus or minus
as per density of the stone.
Other items such as feed tube, top liner plate, etc cost is very negligible and it have much
more life. Due to it's special design there is no wear of the feed tube. Cost of Feed tube and
assembly is Rs 6,000.00. It have Very less Wearing Say negligible, and feed guide ring is
Rs 1200.00. A special design of feed tube develops stone lining so no wear.
Thus the total wear cost will be about Rs 3+ 1.39 + 4.00= Rs 8.39 per ton .
Say Rs 9.00 per ton. Considering 30 % more for hard and abrasive stone it may be Rs 12.00
Maximum. We hope this is much less then any other make. ( it may be around Rs 20 per
100 cft of metal ) These figures are the result of our observation with a particular stone, it
may vary with other stones as per the density and hardness. This is given for your reference,
and should not be treated as binding upon us in every respect.
Wear Cost per Ton ………………………..Rs 9.00………….(2)
This plant should be made fully automatic, feeding, and Conveying must be with the
help of conveyor belts. For a 50 tons per hour machine, Only one operator per shift, and 3 or 4
helpers per shift will be sufficient to run the machine.
Operator Salary (One operator)…………………..Rs 4000 per shift Helper Salary (four Helpers)……………………Rs 10,000 per shift
This comes to total 14,000 Maximum. Which will come to
Rs 1.4 per Ton.
Labor Cost per Ton………………………..Rs 1.4 ……..(3)
The V.S.I Crusher is oil lubricated, the oil is required to be changed approximately 6 to 8
months. About 70 ltrs of oil is required each time. Which cost about Rs 4500.00 Which will come< out per Ton Rs 0.08 (Very negligible.) will be about Total will be about say Rs 0.08 per Ton.
Lubricating Cost per Ton comes to Rs 0.08 .............. (4)
Saving in Oil Lubrication Cost Compared to Grease Lubrication systems is about
Rs 1,15,000.00 per year. (Detail of this comparison is given on separate sheet) 3
Thus the total Cost of Crushing one ton Metal comes to total of 1+2+3+4 items. =
Power Charges + Wear Cost+ Labor charges + Lubricating Charges =
Rs 14.75+ Rs 9.00 + Rs 1.4 + Rs 0.08 = Rs 25.23 per Ton. Say Rs 25.5
Weight of One Cu Mtr metal is about 1600 Kg So Crushing
Cost per Cu Mtr will be Rs. 40.8 say Rs. 41.00
If the cost of Stone is added to this cost, it will give the production Cost of the Metal.
(This figure is given for general idea, There may be some variation for place to place and stone
to stone, so should not be taken as binding upon us in every respect.) |
