Bottom Discharge Centrifuge Manufacturers in India
Febchem Engineering Pvt. Ltd. manufactures high-performance Bottom Discharge Centrifuges designed for efficient solid-liquid separation across a wide range of industrial applications. Our robust and reliable centrifuge systems provide automatic cake discharge, high separation efficiency, and consistent performance for the pharmaceutical, chemical, food processing, and process industries.
What Is a Bottom Discharge Centrifuge?
Bottom Discharge Centrifuge is used to separate a mixture that consists of two substances with different densities by using the centrifugal force resulting from continuous rotation.
In Bottom Discharge Basket Centrifuges, cake is scrapped (through a scrapper operated either manually, pneumatically, or through a hydraulic cylinder) and discharged from openings in the basket bottom and inertia plate while the basket rotates at a slow speed.
How Does a Bottom Discharge Centrifuge Work?
The system is designed to handle a wide range of crystalline, granular, and slurry materials while maintaining high separation efficiency. Its robust construction and controlled discharge mechanism help improve productivity, reduce downtime, and ensure reliable operation in demanding industrial processes.

Benefits of Bottom Discharge Centrifuges
Bottom Discharge Centrifuges offer several operational advantages for industrial processes that require effective solid-liquid separation and controlled cake removal.
Automatic Cake Discharge
The scraper-based discharge mechanism removes the collected solids through the bottom opening, reducing the need for manual cake removal.
Reduced Manual Handling
The bottom discharge arrangement helps minimise direct operator involvement during cake unloading.
Efficient Solid-Liquid Separation
Centrifugal force supports effective liquid removal and solid cake formation during batch processing.
Improved Process Control
VFD-controlled operation allows speed adjustment during different stages of the separation cycle.
Reduced Product Handling
A controlled discharge arrangement helps reduce unnecessary handling of separated material.
Suitable for Industrial Applications
The machine can be configured for different pharmaceutical, chemical and food-processing requirements.
Bottom Discharge vs Top Discharge (Bag Lifting) Centrifuge
Bottom Discharge and Top Discharge Centrifuges are used for solid-liquid separation, but they differ in their cake removal arrangements and operating requirements.
| Comparison Factor | Bottom Discharge Centrifuge | Top Discharge / Bag Lifting Centrifuge |
|---|---|---|
| Cake Removal | Scraper removes cake through bottom openings | Filter bag and cake are lifted out from the top |
| Discharge Arrangement | Bottom discharge | Top discharge |
| Material Handling | Scraper-based cake removal | Bag-based cake removal |
| Operator Involvement | Reduced manual cake handling | Involves filter bag handling |
| Operation | Batch operation | Batch operation |
| Typical Application | Depends on material and process requirements | Depends on material and process requirements |
How to Choose the Right Bottom Discharge Centrifuge?
Selecting the right Bottom Discharge Centrifuge is important for achieving effective separation, suitable cake dryness and reliable batch processing. Before selecting a machine, consider the following process requirements.
1. Particle Size and Solids Concentration: Understand the particle size and percentage of solids present in the slurry.
2. Filtration Characteristics: Evaluate the filterability of the material and the type of filter medium required.
3. Batch Capacity: Determine the required batch size and production volume to select a suitable basket configuration.
4. Material of Construction: Select SS 304 or SS 316 according to the chemical properties and corrosion requirements of the process.
5. Cake Washing Requirements: Identify whether the process requires cake washing and additional moisture removal.
6. Hazardous Area Requirements: Consider process requirements for explosion-proof equipment, nitrogen blanketing and solvent handling.
7. Automation Requirements: Decide whether manual controls, PLC, HMI or additional monitoring systems are needed.
