Unless you're working in petrobond sand (and intend to do a production run using more than two wheel barrows full of sand mix) a muller is a waste of time, money, and space for the small amount of work you guys generally do. If you're working entirely in green sand then all you need is a seive screen you can work batches through by hand. You can process and/or recover two wheel barrows full of sand (approximately four 18 x 24 plaque molds worth), in about 20 minutes. Make yourself a seive that's automated and you can process a ton of sand within an hour.

There's wealth of learning to be had in doing everything by hand, particularly so in developing a sand mix while learning this process. You get to a point where you're at your best quality then you tend to experiment more till you either deminish it or improve. There are times i actually degrade my sand mix to produce an effect no other foundry could accomplish with what they have to work with. This is where keeping a journal of everything you do, including the effects achieved off of your failures, LOL.... helps out. But like I've said often to others, it's not just the sand mix... it's SOOOOOO MANY other things one has to dial in to make an effective and quality cast each and every attempt. Like a book i once read on the subject of casting metal, the author said, ... "everything there is to know about casting bronze and aluminum can be printed in a book thin enough to fit in a tee-shirt pocket. To apply this knowledge, and master it, however, will take a minimum of 20 years and as much as a lifetime." I'm here to tell ya, Mike... that's the silver ring of truth in that quote. The only thing I can add to it is... "you get out of it proportionate to what you put into it".

I totally agree with that quote Frank.....Today I took 5 kgs of my greensand and added 100 grams of corn flour and that sure increased the green strength
