OPEN & CLOSED CIRCUIT Self contained breathing apparatus can be divided into two main categories open circuit systems and closed circuit systems An open circuit system supplies the wearer with fresh oxygen and releases the carbon dioxide expelled by the wearer to the outside atmosphere through a valve in the facepiece
·The data obtained was compared to a simplified relationship for closed circuit grinding performance model developed by Magdalinovic in 1991 to quantify the effect of classification efficiency
·With a closed circuit breathing apparatus commonly known as a rebreather the exhaled gas is scavenged scrubbed of carbon dioxide enriched with oxygen and then sent back to the diver in the breathing loop The oxygen consumed by the diver via metabolic consumption is the only thing replaced to continue to sustain the diver
3 ·In a closed recirculating water system water circulates within a closed loop continuously moving through the system and undergoing cooling or heating processes before being reused Closed recirculating cooling systems optimize industrial processes while reducing water consumption and environmental impacts and play a key role in sustainable
·The requirement of the HPGR circuit is to reduce this feed to an 80% passing size of mm by operating the HPGR in closed circuit with a vibrating screen The target circuit throughput rate is 1000 tph This material is then to be fed to a ball mill in closed circuit with hydrocyclones with a target overflow P80 of 150 μm see Table B1 and B2
·The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow resulting in a classification efficiency of 50% This efficiency was chosen as an industrial practice average from the data presented in Fig 6
The crusher in closed circuit is then used to reduce the size of the critical size material and return it to the mill As the pebble ports also allow steel balls to exit An example SABC A circuit is the Cadia Hill Gold Mine New South Wales Australia Dunne et al 2001 The project economics study indicated a single grinding line
