PSLQ450
The PSLQ/PSFQ series Batch Type Full-open-lid Basket Centrifuge is a piece of vertical type clean filtering equipment with intermittent operation. The materials enter the bowl from the feeding pipe on the closed housing. Under the action of centrifugal force, the liquids are discharged outside the machine after passing through the filter media. The solids are retained in the bowl and discharged from the top when the cover is opened after the machine stops. The cover can be turned totally at a turning angle higher than 90° through manual, hydraulic driving or pneumatic driving mode, so that all the parts of the bowl are exposed, making it convenient to carry out discharging, cleaning, filter bag replacement, etc. The whole machine is manufactured in accordance with the requirements in GMP and FDA. It is subject to polishing treatment without any dead corner. The PSFQ model centrifuge adopts motor direct driving and avoids dust that may be caused by triangular belts and mechanical braking. It is especially suitable for inflammable, explosive and poisonous applications.
It is widely used for separation and dehydration of suspensions containing solids of middle or fine granularity such as food additives, chemical condiments, MSG, pesticides, antibiotics, pharmaceutical intermediates, vitamins, Chinese patent medicines, activated carbon, dye intermediates, pigments, etc. in pharmacy, light industry, food, chemical industry, etc.
Fine chemicals, inorganic salt crystals, chemical intermediates, resin particles, solvent recovery
Pharmaceutical API, pharmaceutical intermediates, herbal extract separation
Food additives, citric acid, starch processing, edible salt
New energy materials, lithium-related salts, rare earth salts, ceramic powder
Wastewater salt recovery, sludge dewatering, hazardous waste treatment

Q1: What materials are suitable for batch type basket centrifuge? What materials are unsuitable?
A: Suitable for solid-liquid separation of granular and crystalline solid materials, such as salt crystals, traditional Chinese medicine extracts, chemical intermediates, resins, and food additives.
Not suitable for: materials with extremely fine particles that are easily penetrated by filters, materials with extremely high viscosity, materials that are prone to flocculation and sticking to the wall and are difficult to discharge; flammable and explosive high-risk materials require explosion-proof configuration.
Q2: What are the key parameters to consider when selecting a suitable model?
A: The main factors to consider are the drum diameter, drum volume, loading limit, rotation speed, separation factor, motor power, and filter media type. Also, confirm the material properties: corrosiveness, whether it is explosion-proof, temperature, and solid content.
Q3: What is the separation factor, and how should it be referenced when selecting a suitable model?
A: The separation factor represents the centrifugal separation capability; the higher the value, the stronger the separation capability. For crystalline materials, it is generally 800-1200; for fine particulate materials, it should be appropriately increased; for fragile materials, the value should not be too high to prevent particle breakage.
Q4: Why do different manufacturers have different loading capacities for the same drum diameter?
A: It is determined by the effective depth of the drum and the loading limit. You can't just look at the volume. You must abide by the rated loading limit of the equipment. Overloading will cause violent vibration and cause safety hazards.
Q5: How should a batch type basket centrifuge be configured for explosion-proof applications?
A: It is equipped with an explosion-proof motor, explosion-proof electrical control, anti-static configuration, nitrogen protection interface, sealed cover, explosion-proof valve, etc.; explosion-proof of the whole machine does not mean that the motor is explosion-proof. Explosion-proof certification of the whole machine is required. You cannot just replace the motor.
Q6: How to select equipment materials for corrosive materials?
A: SS304 for normal working conditions; SS316L for moderate corrosion; Hastelloy or PTFE lining for strong corrosion; avoid using ordinary SS304 for materials containing chloride ions.
Q7: How is material typically discharged from a batch type basket centrifuge?
A: Basic model: manual upper shoveling; hanging bag model: direct lifting of filter bags for discharging; high-end model: fully automatic scraper for bottom discharging.
Q8: What should be noted when feeding materials?
A: Low or medium speed feeding is required; high speed and large-volume feeding are strictly prohibited. The material should be distributed as evenly as possible inside the drum to prevent severe vibration caused by uneven loading. For materials with large fluctuations in solid content, try to ensure that the feed concentration is stable.
