Fertilizer process solution
Fertilizer Slurry Filtration & Cake Washing
A filtration route built around wash duty and product handling
Fertilizer and phosphate process streams differ in solids, liquid value and washing needs. Hexin reviews the feed and desired cake or filtrate outcome before proposing equipment, washing stages and discharge interfaces.

Define the value of each process stream
Washing is useful only when it serves a verified purity or recovery objective. The process design starts by identifying what must stay in the cake and what must leave with the liquid.
Slurry composition, particle size and mother liquor determine filterability and component compatibility.
Specify what soluble material must be removed or recovered and how wash liquid will be managed.
Capacity, availability, filter-cloth care and downstream cake handling shape the line layout.
Process selection
Separate first. Wash only as needed.
A staged route can combine cake formation, optional washing, drying and discharge, but the number of stages must follow tests and a mass balance.
Characterize
Document feed composition, solids load, liquid value and handling target.
Test formation
Measure filtration rate, cake release and filtrate separation.
Test washing
Compare wash stages against required purity or recovery and water demand.
Configure line
Specify filtration, wash supply, discharge, controls and utilities.
Final equipment configuration and achievable results require representative material testing and project engineering.
Equipment in the process
Match the filter to the duty
Equipment selection and washing stages should follow representative material tests and the project mass balance.
Horizontal Vacuum Filter
Continuous filtration with configurable washing and cake discharge where tests support a belt route.

TFP Vertical Automatic Pressure Filter
An alternative for duties requiring a tested pressure cycle and optional cake washing.
Explore Equipment →The number of washing stages, construction materials and filtrate streams should be defined from test data and the project mass balance.
Proof before specification
Prove the washing duty before sizing
For fertilizer-process slurries, wash-stage performance must be established with representative feed and a clear recovery or purity target. View Related Case →
Cake formation
Measure filtration rate, cake permeability and discharge with representative process slurry.
Wash response
Test impurity removal or product recovery against wash volume and stage count.
Process interfaces
Document filtrate segregation, wash-liquid supply, corrosion requirements and acceptance criteria.
From selection to operation
Coordinate washing with the whole plant
A proposal should define feed, wash-liquid supply, filtrate segregation, cake discharge and site responsibilities together.
Process review
Confirm what is being recovered, removed or retained in each stream.
Stage configuration
Specify filtration and washing stages, equipment materials and controls.
Project support
Agree factory checks, installation, commissioning and training for the chosen scope.
