Crystallization from melts . Equipment for crystallization from melts differs considerably from the solution crystallizer. The article discusses: Trough crystallizers, belt crystallizers, pastillators, flakers, screw crystallizers, and prilling towers. The kinetics of melt crystallization is simpler than that from solution, and the secondary nucleation becomes less important. Environmentally, crystallization from melts is more attractive because absence of solvent obviates waste products. Dust problems are avoidable by flaking, pastillizing, and prilling.
