• A new cone has been introduced as a tertiary crusher in a plant • Target product is 57’s (1” x 3/8”) –Most of the time they don’t have much market for 89’s (-3/8”x#4) or the fines • A bigger cone was put in place, so we have to be careful on how much recirculating load builds up or we will overflow the belts

It is stated as a percentage of the new feed to the crusher. The equation for circulating load percentage is: R = 100/E/r-1 where R = circulating load, % E = screen efficiency, % r = % oversize in crusher product. To help understand this determination and the equation use, take the example of 200 tph original or new material to the crusher.

If it isn''t already running, turn on your pool pump and keep it running for the next 24 hours. Increase the pH to 7.8 to 8.2 for five days after treatment, adding borax or soda ash. Borax is preferable as soda ash tends to raise the total alkalinity and pH. Wait seven days and test the water hardness again.

Pressure tests are a non-destructive way to guarantee the integrity of equipment such as pressure vessels, pipelines, plumbing lines, gas cylinders, boilers and fuel tanks. It is required by the piping codes to confirm that a piping system is able to bear its rated pressure and it has no leaks. The most widely used code for pressure and leak test is the ASME B31 Pressure Piping Code.

Note that the above calculation of impact force is accurate only if the height h includes the stopping distance, since the process of penetration is further decreasing its gravitational potential energy.. The average impact force calculated here is the average over distance, which can be presumed to be proportional to, but not the same as, the average over time.

h = m, then the velocity just before impact is v = m/s. The kinetic energy just before impact is equal to its gravitational potential energy at the height from which it was dropped: K.E. = J. But this alone does not permit us to calculate the force of impact! If in addition, we know that the distance traveled after impact is

Impact breaking is a kind of crushing machine which uses impact energy to crush materials. When the material enters the action area of the plate hammer, it will be broken by the high-speed impact of the plate hammer, and it will be thrown to the impact device installed above the rotor to be broken again, and then it will bounce back from the impact lining plate to the action area of the plate
