■Reasonable structure design. The CIP cleaning system (spraying system) ensures the requirements for cleanliness and conforms to the GMP standard.
■The automatic actuating elements adopt the pneumatic system, which is clean and sanitary.
■Electromechanical material layer control.
■The optional gas-assisted scraper ensures there is no residual cake in the bowl after discharge.
■Foundation-free installation, simple structure, beautiful appearance, convenient cleaning.
■Vibration damping and isolation system with scientific and reasonable design. The balancing block and imported high-precision liquid damping agent type vibration isolator is adopted. The equipment vibration is totally absorbed by the vibration isolation system without vibration interference to foundation grounds and surroundings.
■The equipment foundation balance plate can serve as an operation platform with more convenient operation and maintenance.
■Safety protection: rotation speed detection, over-vibration protection, uncapping protection, motor overload and overheat protection, scraper turning and lifting machinery electric dual-control, linked locking of scraper and bowl.
■Structure: The housing is equipped with the feeding pipe, washing pipe, sight glass, exhaust port, and lighting hole. The closed structure, bowl, housing and cover are made of stainless steel SUS304. The machine base is made of castings. The surface is coated with stainless steel. The interior and exterior surfaces of bowl and housing, and the surface of exposed parts in the machine are all subjected to polishing treatment.
■All fasteners are made of stainless steel.
■PLC control is adopted.
■Electromechanical material layer control.
■Driving and braking: ordinary motor (or explosion-proof motor) + frequency converter + dynamic braking.
■Pneumatic system or hydraulic system.
■Foundation-free type (balancing block + imported high-precision liquid damping agent type vibration isolator).

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: 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.
