Banjo spray bars

I have had a few discussions with members recently about spray bars on banjos!! the common problem was that every one was getting wet !!! well guys its not a fault!I find that if you have not got a water haze around the top section of the banjo ,you dont have the pressure high enough!! You need the water at such a pressure to cut the clay and keep it in suspension whilst it travels down the riffle tray . This is why James 101 hammers on about the levels of the top and bottom hoppers and while on the topic of angles ,dont forget that you are shovelling in the Banjo and hitting the front of it so every now and again CHECK that the front legs arnt driven so far into the ground that the angle is way too steep on the bottom box

Spot on with the angles and how easy they can change! As much as it's a pain to carry more equipment, the old spirit level helps out heaps not only for changes, but for setting up in the first place! You can easily think your standing on flat ground when your not even close to being right? Even a small level a straight edge and a couple of different size small blocks of wood of pre determined size will give you the same set up every time! "No guess work".

Spray bars on banjos!! And getting wet !!! It all comes back to the way you operate or have been shown to operate your unit. Yes the levels on your Banjo are very important more so when it comes to getting wet, the angle of your jetting must be right if it is hitting the side wall of the hopper your going to get wet. Pressure is another factor as Murachu has stated and only experience can teach you on just how much pressure you will require to process the material you are working. But most importantly it is the wind or breeze you must consider and learn to work with. When setting your unit up it dose not matter which type of highbanker you have make sure the wind or breeze will blow the spray in the opposite direction to which you are working simple but often overlooked. The above all helps to stay dry it’s not so bad in summer but a bugger in winter. Cheers.

This is how your spray bars should work.

This is how the Spray bars should look when working right. It's only a short video but it will give you a better idea. cheers
