Centrifuges play a critical role in separating solids, liquids, and mixtures in industrial processes. From chemical production to food processing, these machines ensure reliable separation, improved product purity, and consistent throughput. While new centrifuges can be expensive and require long lead times, many facilities prefer used and surplus centrifuges because they offer dependable performance at a significantly lower cost.

If you are planning to expand capacity, replace aging equipment, or support new processing requirements, understanding the value and types of used centrifuges can help you make an informed decision.

What Are Industrial Centrifuges?

Industrial centrifuges are mechanical separation devices that use high rotational forces to isolate components based on density. When a mixture is fed into a spinning bowl or basket, heavier materials move outward while lighter components move inward, enabling efficient separation.

At JM Industrial, we supply a wide range of used, unused, and surplus centrifuges sourced from industrial facilities across the U.S. Each unit is inspected for mechanical integrity, operational reliability, and cleanliness before being listed for sale.

Why Industries Choose Used Centrifuges

1. Significant Cost Savings

Used centrifuges offer substantial financial advantages. Instead of investing heavily in new equipment, industrial plants can acquire high-performing centrifuges at a fraction of the cost.

2. Immediate Availability

New centrifuges often involve long manufacturing cycles. Used and surplus units allow facilities to upgrade or replace equipment without operational delays.

3. Proven Performance

Used centrifuges originate from operational environments, which means their reliability and efficiency have already been tested under real industrial conditions.

4. Environmentally Responsible Choice

Reusing industrial equipment supports sustainability goals by reducing manufacturing waste and extending equipment lifespan.

Types of Used Centrifuges Available for Industrial Applications

1. Decanter Centrifuges

Decanters continuously separate solids from liquids using a rotating bowl and screw conveyor.

Advantages:
• Ideal for high-solids content mixtures
• Continuous operation
• Excellent for large-scale processing

Common Uses:
Wastewater treatment, chemical slurries, food byproducts, mineral processing

2. Basket / Batch Centrifuges

These centrifuges use a perforated basket that spins at high speed to separate solids from liquids.

Advantages:
• Simple design
• Effective for batch separation
• Can handle coarse solids

Common Uses:
Pharmaceutical powders, food ingredients, industrial chemicals

3. Disk Stack (Disc Bowl) Centrifuges

Disk centrifuges use stacked conical discs to maximize separation efficiency for fine particles.

Advantages:
• Excellent for fine particle removal
• High throughput
• Suitable for heat-sensitive products

Common Uses:
Oil purification, dairy processing, beverage clarification, biotech fluids

4. Tubular Bowl Centrifuges

A high-speed vertical bowl separates fine particles or immiscible liquids.

Advantages:
• High G-force
• Superior clarity
• Excellent for low-concentration solid removal

Common Uses:
Pharmaceuticals, essential oils, chemicals, fermentation broths

5. Peeler Centrifuges

These centrifuges use a scraper mechanism to remove cake solids from the rotating basket.

Advantages:
• Gentle handling
• Automated operation
• Suitable for crystals and fragile solids

Common Uses:
Fine chemicals, specialty salts, starch, and polymers

Industries That Rely on Used Centrifuges

Used centrifuges are widely used in industries that require continuous, reliable, and high-efficiency separation:

• Chemical Manufacturing

• Pharmaceuticals

• Food & Beverage

• Wastewater Treatment

• Oil & Gas

• Plastics and Polymers

• Mining & Minerals

• Biotechnology

Each industry selects centrifuge types based on mixture characteristics, solids concentration, and product quality requirements.

Factors to Consider When Buying a Used Centrifuge

1. Material Characteristics

Know whether your mixture contains fine particles, coarse solids, multiple liquid phases, or heat-sensitive materials.

2. Desired Separation Level

Choose based on clarity requirements — coarse separation, fine polishing, or high-purity clarification.

3. Speed & G-Force

Higher G-force improves separation efficiency but must match your process needs and product limitations.

4. Bowl Size & Throughput

Ensure the centrifuge can handle your required processing capacity (batch or continuous).

5. Construction Material

Stainless steel, Hastelloy, or other corrosion-resistant alloys may be needed depending on chemical compatibility.

6. Drive System & Controls

Check motor integrity, variable speed options, and whether the unit is compatible with your plant control system.

7. Maintenance History

Reliable suppliers provide:
• Inspection records
• Mechanical condition reports
• Wear component checks (bearings, seals, bowl integrity)
