sorry for hiding under a different screen name on YouTube, if you need more pictures of the muller let me know.
the short version is that like Mayhem said oil bonded sand has to be mixed under pressure to get the clay/Bentone/Petrobond to mix when mixing new sand. and to recondition the sand for reuse it has to be what is called mulled or mixed under pressure to get the clay to rebond to the burned sand.
the sand in the video is new thats the reason for the red color, actually the red color is due to the iron oxide in the clay. The sand in the first picture is over a year old and has been reused I don't know how many times, I just have to add a little bentone and oil and catalyist to it from time to time.
