Choosing the Right Centrifuge Machine for Your Industrial Needs

March 08, 2024

In many different fields, centrifuges serve a variety of purposes. Centrifuges are a powerful instrument for separating solids from liquids, and they find widespread use in many scientific and industrial processes. When shopping for a chemical centrifuge, there are many options to consider because there are many different models. You should know how different centrifuges function and what they're used for before purchasing them; otherwise, you might end up with equipment unsuitable for its intended use.


The centrifuge machine in pharmaceutical industry is just one of the many products offered by Shenzhou Machinery, which also boasts extensive experience designing and installing filtration systems. Below are a few of the many centrifuge types available and descriptions of their best uses to help you better comprehend their versatility in an industrial context.

Understanding Separation Requirements

"Defining a problem is half the solution," as the adage goes. Having a distinct idea of what you need from the separation and what you hope to achieve is critical. You must know the fluid type and the contaminants' types and quantities to specify your separation requirements.


At this early point, you have likely thought about several separation technologies, including settling, filtering, hydro-cyclones, filter presses, screw presses, and similar apparatus. These technologies are highly specialized and have limited generalizability. One way to reduce the pool of potential solutions is to grasp your unique needs fully.

The Different Types Of Centrifuge

Decanter Centrifuges

Decanter chemical centrifuges are called horizontal bowl centrifuges because of their distinctive design. Their capacity to manage large amounts of work makes them ideal for industrial use. Since they can run nonstop, fewer people will need to be involved. Wastewater treatment, sludge dewatering, waste oil management, and other similar applications are common for decanter centrifuge food processing.


An inlet pipe feeds the solid/liquid mixture (sludge) into the chemical centrifuge. The solids and liquids are separated using the centrifuge's high-speed rotation. The procedure involves pushing the solid material towards one end, where it is discharged using a helical screw that rotates at a different speed than the bowl. A separate outlet is used to discharge the remaining liquids.

Centrifuges in a Basket

Regarding sugar refining, pharmaceuticals, and certain chemical separations, basket centrifuges—also called centrifugal filters—are frequently employed. One of the most basic centrifuge designs employs a straightforward method for separating solids from liquids. A basket centrifuge food processing gives you more control over the process because it can be either fully automatic, semi-automatic, or manual, depending on the model.


The method employed by the basket chemical centrifuge is exceedingly straightforward. The centrifuge machine in pharmaceutical industry consists of a big drum that houses a basket with holes cut into it. Fine mesh screens are commonly found on the exterior walls of this type of basket. The centrifugal force draws solids to the inside of the spinning basket and forces liquids out through the holes as the basket spins.

Centrifuges for Oil

In many industrial settings, contaminants can be removed from oils, coolants, and other lubricants using an industrial oil centrifuge. Even though it's not rocket science, this filtering method is often considered superior. Your oil or lubricant may get contaminated with particles, usually metal, in an industrial setting. Metal particles (or any contaminants) in this oil could cause machinery damage if it is reused in another process. This is why reusing lubricant, coolant, or oil requires a filter.


The centrifuge machines in the pharmaceutical industry and Oil industries are functionally equivalent to basket centrifuges, except the latter do not use a basket. The basic design of this centrifuge—a single drum spinning at high speeds—makes it both simple and effective. A dense cake-like substance is formed as the drum spins by pushing particles and contaminants to the wall. Oil, being a liquid, is gravity-fed to the bowl's center and then released independently. There are self-cleaning systems available, but sometimes manual waste removal is necessary.

Factors To Consider When Buying A Centrifuge

Be Clear About What To Spin

Determine exactly what you want to spin before settling on a chemical centrifuge. Everything you're currently spinning and anything you could want to spin down the road is a part of this. For instance, you could spin microplates or 10 ml blood collection tubes. Ideally, you'd need two independent rotors for this situation.


For precise measurements in millimeters and milliliters, as well as the names of the tubes or containers you're spinning, precise information is required. Sending a picture and this information to any possible centrifuge supplier will help them understand exactly what you want to spin right from the start. If you don't do this, you might get adaptors or rotor buckets unsuitable for their intended use. Erroneously ordered parts can result in re-stocking fees and additional lead time, leaving you without a usable centrifuge wastewater treatment for an extended period.

Centrifuge speed

Different models and types of rotors allow laboratory centrifuges to achieve varying speeds due to their unique designs. Whether working in RPM, RCF, or "G force," you must choose a measurement for your desired speed. Various online calculators are here to help you determine the RCF. Despite the angled separation for centrifuge wastewater treatment, fixed-angle rotors typically outperform swing-out ones in speed. Usually, therRotor speeds of 4,000 to 5,000 rpm are easily within the range of most laboratory centrifuges. The typical maximum speed for fixed-angle ones is about 18,000 rpm.

Centrifuge size and capacity        

Due to the ever-increasing amount of laboratory equipment, many laboratories have limited bench space. The room's actual dimensions don't grow proportionally, though! Before shopping for a centrifuge, measure the area where you intend to put it in your laboratory to ensure it will fit.


This is especially important if you're short on space. Remember that a 30-centimeter clearance between the centrifuge and any nearby walls or sharp objects is required for safety. The reason is that the centrifuge must spin on its axis in case of disturbance.  The additional room also allows for sufficient airflow to keep things cool. Consider using a lockable castor trolley to move your centrifuge machine in chemical industry around your workspace if you're short on bench space. If you want to ensure the trolley fits your centrifuge perfectly, it's best to get them straight from the manufacturer.

Refrigerated Or Non-Refrigerated Centrifuge

Do you need to keep your samples at a certain temperature while spinning them in a centrifuge machine in chemical industry? If so, you will require a refrigerated centrifuge. Remember: the rotor and buckets will generate considerable heat while spinning at several thousand revolutions per minute. If you are spinning something like blood, for example, then you will most likely need a refrigerated centrifuge. But if you are not spinning anything sensitive to temperature, you can opt for a non-refrigerated centrifuge. Some people refer to non-refrigerated centrifuges as ‘air-cooled.’
