Polishing Barrel Drum
Wire Nails are produced by wire Nail Making Machines. The Nails are to be polished as well finished products. The quality of the Nails produced depends upon the wire used on the Machine.
Generally, the wire received from the supplier is found dull due to the Wire Drawing process and also sometimes gets rested due to weather effects. The wire for the process of cutting Nails is not so bright as a result, the Nails produced do not have brightness and shine.
Such finishes are never acceptable to buyers. Thus, the Nails do require polishing which results in attractive finished products.
To overcome this difficulty, the machine known as a Polishing Barrel Drum has been devised. The polishing barrels are available in two sizes viz. 250 kg and 500 kg. Capacities per charge.
1) Load the polishing barrel with wire nails 3 to 4 inches above the half size of the barrel and the remaining portion with Saw Dust. If the Nails are found rusty, it is advisable to mix a little quantity of paraffin oil (Half litre Kerosene) prior to loading of Saw Dust. Rotate the barrel with blind lid on, for about 10 minutes. After this process, load the barrel with Saw Dust and rotate the barrel for about 30 minutes fixing the blind lid-take out the blind lid and fixing up the perforated lid to take out Saw Dust from the barrel by rotating. Continue this process again for about 40 minutes loading the barrel with fresh sawdust. This will result in a bright shining look of Wire Nails. The Saw Dust used in the second sequence can be re-used for the first cycle of the same process in the next batch. This ensures the economy of Saw Dust and solves the storage space.
2) If the mirror finish is required on the Nails, it is advisable to use SOFT LEATHER PIECES in the second sequence of polishing instead of Saw Dust, 15 to 20 kg. of such LEATHER PIECES are required for 250 kg. Capacity Polishing Barrel. These LEATHER PIECES can be applied again and again for about 15 to 20 cycles till they become very oily.
