There's a company that does quite alot of cable granulation about an hour from me, and I bought a dump trailer just for their waste. Should tell you everything right there. The table needs these factors for variability because of two things, strand size and weight and as time goes by on the knives you will start to increase the heat they produce, on vinyl insulation such as computer stuff, LV cable etc, they tend to "stick" just a bit so a more violent stroke is needed to throw the product with an increase in the declination. I try not to post process at all any vinyl insulated product, it will make it worse.
Best brand for an air table is Guidetti, they are made in Italy, and from their website they do have UK support. You normally cannot order a table by itself as they are part of a full system, just let your sales rep know your intention, tell them the feed rate and they should be able to get you a table that will work for you.
