I built one a few years ago.
Farm & Fleet - 310 gal cone bottom tank with stand.
Chemical resistant trash pump
1.5" hose
Various fittings and valves
Trash pump sucks material out the bottom and it is pumped along the outside of the tank back up to the top and gets discharged back into the tank. A T and some valves allow me to open up the sprayer fill hole and divert some or all into the sprayer.
Awesome for melting down fert. I only use for fertilizer breakdown, all turf chemicals are added to each sprayer tank. Great for quick fill applications, especially if you spray at high volumes and multiple tanks. Total cost was ~$1000.
