TAKING CARE OF YOUR PLANT'S CYCLONES IN ORDER …
a mere 15%, the profit generated by a single 1000mm cyclone under these conditions is enough to pay for that cyclone in just more than a single shift's time (R300,000 ÷ (R132.22 ÷ 2 x 15%) = 8hrs 25min). Generating a profit in the order of R10/sec it becomes clear why it is worthwhile to ensure the cyclone is operating optimally.
