All you need is an export bus and some sort of way to import back in. TE auto exports, but if you want to reduce entity lag entirely, having directly attached import buses/interfaces will alleviate that problem.
I would also suggest going for induction smelters, since you skip the dust stage entirely. You can pulverize the infinite cobble you have for the sand you require.
