 · CNC turning is usually priced lower at 35 per hour, while the machine cost per hour of multiaxis CNC machining typically ranges between 75 and 120 or higher. On the other hand, the hourly rate of industrial 3D printers varies between 1020 for industrial SLS or FDM machines to more than 100 per hour for metal SLM and DMLS 3D ...

 · The Pollution Index PI of any industrial sector is a number from 0 to 100 and the increasing value of PI denotes the increasing degree of pollution load from the industrial sector. Based on the series of brain storming sessions among CPCB, SPCBs and MoEFCC, the following criteria on 'Range of Pollution Index 'for the purpose of egorization of industrial sectors is finalized.

How the mining industry prevents arsenic pollution . A number of technologies are being used to capture and remove arsenic from smelting stacks and mine tailings.
