A closed circuit allows current to flow but an open circuit leaves electrons stranded Picture a gallon of water flowing through an open pipe The water will flow for a short time but then stop when all the water exits the pipe If you pump water through a closed pipe system the water will continue to flow as long as you keep forcing it to move

The same methodology has been successfully applied to other closed circuit cement mills with productivities ranging from 30 t/h to 90 t/h depending on the size of the circuit and the CEM type produced In cases where the flow rate of the material returned from the separator is measured then this variable can also be used as a process variable The corresponding dynamics between feed and

One of the significant difference between the open loop and closed loop control system is that in an open loop system the desired output does not depend on the control action While in the closed loop system the desired output depends on the control action of the system The other differences between the open and closed loop system are shown below in the comparison chart

For primary grinding the ratio could vary between 1 1and 1 For fine regrinding in open circuit the ratio ranges from 1 to 1 Some ball mills are separated in to compartments by grates The grates hold back particles above a certain size for additional grinding The compartments could contain different ball sizes Large to small

One circuit had two mills installed in series with the first mill operating in an open circuit and the second mill in a reverse closed circuit The second grinding circuit involved two mills operating in parallel both in direct closed circuits The results indicated that the parallel circuit produced 20% less slime than the series circuit with an additional % throughput in the flotation

Closed Center Versus Open Center Hydraulics If you ve been working with hydraulics for a while you probably consider a hydraulic system with a variable displacement pump to be more efficient than its fixed displacement counterpart As a generalization this is true but like most things in hydraulics it depends

So no live circuit must be open otherwise closed through the isolator process A complete live closed circuit should not be opened through the isolator process also a live circuit should not be closed as well as completed through the isolator process to keep away from huge arcing among isolator contacts So this is the reason isolators should be open once the circuit breaker is open
