Continuous Pusher Centrifuge for Chemical Crystal Dewatering is designed for continuous solid-liquid separation of chemical crystals, crystalline slurry, and crystallizer discharge slurry in chemical production lines.
In many chemical processes, crystals are formed through cooling crystallization, evaporation crystallization, reaction crystallization, or concentration. These crystals often carry mother liquor, soluble impurities, or process liquid after crystallization.
A pusher centrifuge removes free liquid through centrifugal filtration and continuously discharges the dewatered crystal cake before drying, cooling, screening, or packaging.
| Output Phase | Typical Composition | Main Purpose |
|---|---|---|
| Chemical Crystal Cake | Product crystals, granular solids, crystalline wet cake | Recover solid chemical product and reduce free liquid |
| Mother Liquor | Process liquid containing dissolved salts, chemicals, or residual reactants | Separate liquid from crystals for reuse, recovery, or treatment |
| Wash Liquor | Washing liquid after product cake washing, if used | Remove residual mother liquor or soluble impurities |
The actual separation result depends on crystal size distribution, crystal shape, slurry concentration, liquid viscosity, screen opening, washing requirement, and operating parameters.
Chemical crystallization products often need stable dewatering before drying or further processing. If liquid carryover is too high, the plant may face:
A pusher centrifuge continuously separates mother liquor from chemical crystals. When required, wash liquid can be sprayed onto the crystal cake to reduce soluble impurities or residual mother liquor.
Chemical crystal slurry enters the centrifuge through the feed pipe and is distributed evenly onto the rotating screen basket.
Under centrifugal force, mother liquor passes through the screen opening and is collected as filtrate. Chemical crystals are retained on the screen surface and form a filter cake.
The pusher mechanism moves the crystal cake forward step by step. During this movement, the cake continues to lose liquid. If product washing is required, wash liquid can be sprayed onto the cake to remove residual mother liquor or soluble impurities.
Finally, the dewatered chemical crystal cake is discharged continuously from the basket end and sent to the dryer, cooler, screening machine, packaging section, or next process step.

The machine supports continuous feeding, filtration, washing, dewatering, and discharge in chemical production lines.
Centrifugal filtration removes free mother liquor from the crystal cake, helping reduce the load on downstream dryers.
The pusher mechanism moves the cake forward step by step, supporting stable and continuous solids discharge.
Wash liquid can be added during cake transport to reduce mother liquor residue, soluble impurities, or surface contaminants.
Proper screen opening and stable cake formation help reduce crystal loss in the filtrate.
The centrifuge can be connected with crystallizers, reactors, evaporators, dryers, coolers, screens, and packaging systems.
Wetted parts and screen segments can be selected according to corrosion, abrasion, crystal size, and process liquid composition.
Under suitable feed and operating conditions, the system can typically help achieve:
Final performance depends on crystal size, particle shape, slurry concentration, liquid viscosity, screen opening, centrifugal force, washing condition, corrosion level, and operating parameters.
To recommend a suitable pusher centrifuge for chemical crystal dewatering, please provide:
It is used for continuous dewatering and washing of chemical crystals after crystallization or reaction.
It can handle free-draining crystalline products such as ammonium sulfate, sodium sulfate, sodium carbonate, sodium bicarbonate, potassium chloride, potassium sulfate, ammonium chloride, and other chemical crystals.
Yes. Washing nozzles can be added to wash the cake and reduce residual mother liquor or soluble impurities.
A pusher centrifuge is a filtration centrifuge using a screen basket. It is suitable for crystals and granular solids. A decanter centrifuge is a sedimentation centrifuge and is more suitable for sludge-like or fine suspended solids.
The screen segment controls filtration performance. Slot opening, material, surface smoothness, and manufacturing accuracy affect cake moisture, filtrate quality, product loss, and maintenance cost.
If you have customer resources or project opportunities in chemical crystal dewatering, crystallization product separation, inorganic chemical production, fertilizer crystal separation, or solid-liquid separation systems, Peony welcomes cooperation.
We support distributors, agents, and project partners with model selection, process advice, customized configuration, equipment manufacturing, installation guidance, spare parts, screen segment customization, and after-sales service.
Send us your material name, capacity, crystal size, solids content, mother liquor composition, and target cake moisture. Our team will help evaluate the suitable chemical crystal dewatering solution.
