Applications
Crystallization routes suited to this equipment family.
Applications include evaporative oslo crystallization and cooling oslo crystallization. Confirm material properties and process conditions before selecting the equipment configuration.
Cooling OSLO crystallization
External cooling generates supersaturation before liquor enters the suspension bed.
Large-crystal production
Suitable duties requiring classified growth and consistent crystal size after process review.
Working Principle
From conditioned solution to classified crystals.
The sequence summarizes the documented process route.
External circulation
Clear mother liquor circulates through the selected heater or cooler.
Supersaturation generation
Evaporation or cooling creates the controlled supersaturated liquor.
Suspension-bed growth
Liquor enters the crystal bed where larger particles contact it first.
Classification & discharge
Crystal residence and withdrawal are managed around the target product size.
Performance Highlights
Crystal growth and classification in one engineered system.
Final performance remains dependent on solution properties and operating conditions.
Large uniform crystals
Classified suspension supports consistent crystal growth.
High production capacity
Continuous operation can be configured across a broad duty range.
Low secondary nucleation
High circulation with low supersaturation supports stable growth.
Reduced crystal breakage
Clear-liquor recirculation limits direct pumping of larger crystals.
