This Ty-Rail Quick-Tensioning System will save you lots of time
How much time do you spend on screen media changeouts? Probably more than you'd like to. According to Haver & Boecker, the traditional way of doing it is not only time-consuming, because it requires removing and replacing many pieces of hardware per screen section, but also costly because washers and bolts are usually lost in the process.
Trying to solve this issue, the company launched its Ty-Rail quick-tensioning system, composed by two tension rails, eight angle boxes, and eight bolts. Once installed, each rail becomes a singular, removable piece since the bolts remain attached to the rail, and the angle boxes remain attached to the vibrating screen. To remove the tension rails, an operator has to loosen the bolts on each, shift the angle boxes up and lift the rail and bolts out as one piece.
As H&B's Tyler Engineered Media Manager, Steve Fair, explained during his presentation at MINExpo International 2016, the new process reduces screen media changeout times by about 50%.
Full presentation transcribed for clarity:
We are introducing something brand new in the industry. We asked our customers what’s the biggest challenge that you have when it comes to screening and the answer was inevitably the same: It’s doing screen changeouts.
There are up to 18 pieces that everybody has to handle every time they do a screen changeout on every rail, and what we’ve done is that we’ve come up with a product that will change that. We’ve turned those 18 pieces into one piece.
So here’s your typical screen changeout. You’ve got a tension rail, and what you have to do is you’ve got to loosen the tension rail off. Normally, you would take the bolts out, you would take the knots out, you would take the washers out, you would take off all of those things, and what we have done is we have turned this into a one-piece project.
Now, normally speaking all of these pieces would have to come off of the bolt in order for it to be taken out, and all of those pieces would have to put down into a box in order for this rail to come out.
Our process, literally, allows you to take it out in one piece. You are probably saving yourself 60% of the time it takes to do this.
You change the screen out. When you are finished changing the screen out, you literally take the one piece and you put it back in as one unit and you tighten it back up.
You put the gates back down, and we’ve gone from a 16-piece project to one-piece process. All done.
