That is a very good screener, but like all devices MUST be setup correctly.

If i am not mistaken those VIBRATORS can be setup with more or less vibration from feed end to discharge end of the length of the deck.

So, theoretically where the load is heaviest........like the FEED END, the amplitude of stroke should be STRONGER to move the incoming heavy load.

as we proceed downward on the screener deck, the vibration should be decrease nominally as the BED DEPTH it has to deal with is LESS AND LESS.

you must have the correct SCREEN TENSION on those wirecloth sections also.

A word with PEP FOLKS would be excellent as they have all the little tricks. ■

I've applied correctly and sold several PEP High Frequency screens in Ontario and continue today representing the Ultra-Vibe High Frequency Screen manufactured by the original owners of PEP in Atlantic Canada.

1st thing I would like to ask, ........ are you trying to screen crushed material or bank run?

High Frequency screens work exceptionally well in crushed material and not very well in bank run. If your screening bank run sand I would recommend changing to a conventional incline screen deck and run it at 1200 cpm.

Assuming your screening crushed stone try the following:

Remove all end caps off vibrators and set the top three vibrators counter weights to setting (5) to get the most amplitude. Set the remaining at setting (3).

Make sure that the aggregate coming off the conveyor feeding the screen is impacting and "aggregate spreader", falling into the feed box and spreading out the entire 6 ft. width of the screen.

Adjust the screen box angle to 41 degrees as a starting point. You can adjust incline slightly more or less if necessary.

Make sure all flow regulators are running at 3 gpm. You can adjust is necessary.

Make sure you are using stainless wire cloth and use a slotted screen. If your sizing a 3/8" chip for example use the cos formula to determine correct slot length. If your pulling out fines at say 3/32" use a 3" slot to maximize open area.

PEP Screens excel in pre-screen and post screen applications.

Happy Screening! ■

Hi Peter........and thanks kindly for your contribution to our forum.....excellent information and i am sure much appreciated.

Wishing you GOOD VIBRATIONS.
