Abstract: Liquid fertilizer is produced by mixing dry fertilizer components with water. The combination is introduced into a first cyclone separator which removes the larger chunks of material from the mixture and discharges them into a crusher containing a revolving paddle wheel. The smaller chunks and the solution are passed to a second cyclone separator where the smaller chunks are removed and passed to the same paddle wheel. The solution containing the dissolved material is passed on to a holding tank. The chucks which were passed to the paddle wheel are broken up by impact with the paddle wheel and the paddle wheel housing and thereafter fall through a discharge chute and become remixed with fluid from the holding tank or storage vat. The fluid and crushed particles are recirculated through the cyclones and crusher or impactor until all particles have become dissolved into the solution.
