A rotary furnace is an industrial heating equipment that processes materials in a rotating drum. The used rotary furnaces are sold for those who want to save costs. They are often used to melt metals like aluminum, copper, lead, and zinc alloys. It's not uncommon for buyers to seek out the benefits that a used rotary furnace can bring to their businesses.
Here's a closer look at some types of used rotary furnaces:
Used rotary aluminum furnace
The used rotary aluminum furnace is an option many foundries are looking into. It offers a cost-effective way to produce more aluminum, reducing raw material waste. Used rotary aluminum furnaces can be found easily in the second-hand market.
Used rotary copper furnace
A significant portion of the world's copper supply comes from used rotary copper furnaces. These are also called shaft furnaces or vertical furnaces. Around 45% of the copper produced globally originates from rotary furnaces. This includes both shaft and cup furnaces. It is estimated that 25% of the copper used in the United States is recycled copper. A large number of used rotary copper furnaces can also be found in the market.
Used rotary смelting furnасе
Used rotary smelting furnaces offer the same concept. They typically have a length that is 4 to 6 times greater than the diameter. They are installed at a slope of around 1 to 3%. Rotary smelting furnaces work by mixing the ore and lime through the fans. The ore is processed at a very high temperature. The sulphur and unwanted parts are separated. The pure metal is extracted and goes into the metal collection vessel.
Used rotary cement furnace
Cement is produced from a rotary кимнатний піч. The raw materials are gathered and milled. The raw meal is then transferred and heated in the rotary cement kiln. Lime, silica, and alumina are the key elements of the cement. When building construction projects, cement is one of the first materials that is required.
Weight :
Typically, used rotary furnaces' weights range from 10 tons to 50 tons. Larger or smaller models are, of course, available.
Material :
Most used rotary furnaces are made from cast iron, but some models may use other materials, such as stainless steel or aluminum alloys.
Dimensions :
Some smaller models of the rotary furnace might have a dimension of around 1.8 m in length and 1.5 m in width. Whereas larger models can be over 3 m in length and 2.5 m in width.
Power supply :
Power supply Rotary furnaces usually have a 3kW 380V or 5kW power supply, which is adjustable according to customer requirements.
fan:
rotary furnaces are generally equipped with a fan of 7.5kW, which also can be adjusted as per customers' needs.
Gas types:
Used rotary gas furnaces can be fueled by natural gas, liquefied petroleum gas, or pipeline gas, or some can use other gas types depending on specific requirements.
Temperature control:
A rotary furnace can precisely control temperature up to 1,600 degrees Celsius.
Production capacity:
A used rotary furnace's production capacity is usually indicated in terms of processing tons per hour. For example, a high-capacity rotary furnace can handle 10 tons of material per hour.
For keeping a used rotary furnace in good condition and performing optimally, it's important to maintain it properly. Here are some tips for maintaining a rotary used furnace:
Regular cleaning:
A dirtier rotary furnace would definitely burn less effectively, which is why it's crucial to regularly clean ones. Even just wiping the dirt would go a long way. For those who don't know, cooking oil can repel dirt and make it easier for people to wipe off grime.
Periodic deep cleaning:
Deep cleaning involves cleaning every corner of the furnace. In this case, ask a professional to clean the unit. A deep professional cleaning can ensure used rotary furnaces work flawlessly and extend their lives for years. Deep cleaning periodically can ensure the tight spots of the furnace get cleaned. Moreover, professionals can quickly and safely remove cleaning products that have been used.
Replace/repair parts as needed:
A good thing about furnaces is that many parts can be replaced over time. So, rather than getting a completely new one, people can spend less by replacing a few key components, which can keep the furnace running smoothly for years. Additionally, in those that wear and tear more easily. Essentially, investing in quality parts can pay off in the long run.
Metal recycling companies are the largest buyers and users of these furnaces. They use them to efficiently recycle non-ferrous metals like copper, zinc, lead, aluminum, etc. The continuous operation and high-throughput t/readings of rotary furnaces make them suitable for handling large volumes of metal scrap, improving productivity.
Many legal and illegal brass manufacturers use a rotary furnace to melt brass. A brass rotary furnace is better than static ones because it mixes the alloy better. It is easier to clean when moving out residue, and more energy is used.
The used rotary kiln furnace is beneficial for the refractory industry. It assists in the production of refractory materials. Such materials can withstand high temperatures, making them suitable to line furnaces, kilns, and a wide variety of high-temperature equipment and industries.
Several metal smelting industries use rotary furnaces to melt ores and non-ferrous metals. These include zinc, copper, and aluminum. Rotary furnaces offer a cost-effective and environmentally friendly way to recover valuable metals from ore.
No dig, oil, or gas drilling companies are looking for ways to increase profits and reduce costs. Many of them have invested in rotary furnaces to conduct their onshore and offshore operations more smoothly. The used rotary furnaces recycle drill pipe and rig as well as other equipment used in the oil and gas industry.
Some automotive aftermarket businesses sell used rotary furnaces to customers who own or work in the following industries:
Used rotary furnaces are ideal for these industries because they efficiently handle electronic waste like circuit boards, cables, and electrical components, extracting precious metals like gold, silver, and palladium. Their versatility and high-temperature capabilities make them suitable for processing various types of e-waste, ensuring effective metal recovery and recycling.
Furnace buyers should keep the following factors in mind when choosing a rotary furnace:
Availability of power supply
Pneumatic and electrical rotary furnaces are common in the market. However, rotary furnaces with air-based mechanisms suit businesses with greater power needs. Buyers with large power needs will find more useable burners with gas power.
Production line compatibly
Active rotary furnaces are essential for production lines that are still in use. A new production line may require a new furnace. An adaptable rotary furnace could cater to different machines in the production line.
Furnace functions and features
Purchase a rotary furnace with the same features. Unnecessary features could raise costs. Special features, such as waterproofing or high temperatures, could improve an item's quality.
Furnace dimension and items
A suitable rotary furnace has the same dimensions and capacity as the required rotary furnace. Extra capacity will incur unnecessary costs.
Condition of furnace and service
The furnace's overall condition and the support staff are critical. Beware of furnaces that need extra parts that are hard to find. Find suppliers that offer extra parts and helpful customer care. Every used furnace will need maintenance and extra parts over time.
Q1: What are the safety precautions for operating a used rotary furnace for melting metal?
A1: Keeping the work area well-ventilated is a must to prevent gas build-up. Operators shouldn't enter the furnace for any reason to avoid the risk of entering death and only certified personnel should handle the rotary furnace. Protective gear like heat-resistant gloves, goggles, and face shields are also a must for protection against molten metal splashes and high temperatures.
Q2: Can a used rotary metal melting furnace be used to melt scrap aluminum?
A2: Yes, a rotary furnace can be used to melt scrap aluminum. In fact, they are commonly used for aluminum melting. One of the advantages of rotary furnaces is that they can accurately control the temperature, making them suitable for melting non-ferrous metals like aluminum.
Q3: Does a used rotary furnace have residual value?
A3: Rotary furnaces may still have residual value even after they are used and worn out. This is because they can still be refurbished and used by some industries or sold as parts to be used for repairing other furnaces.
