The rolls of this double-head rolling mill can be customized for different output, finished product size and finished product type requirements. It can largely solve the problem of resource utilization, and the two sides can be flexibly designed to achieve maximum output and efficiency.
Shape
The processed material will finally be presented in the shape of a sheet or wire, and the sheet mainly pays attention to its maximum and minimum thickness. In addition to determining the required size of the wire, the shape of the finished product should also be specified. Grooves made of wire can be customized as round or square.
Metal
The hardness of different metals is different. Double head rolling mill uses cold rolling method, which is more suitable for ductile metals, such as gold, copper, silver, copper, platinum, palladium, rhodium, etc., can be processed by rolling mills. When these metals fail to work, it is only necessary to anneal the material and then process it.
Size
For sheet material, the maximum feeding width of the machine can reach 190mm, the thickness can be realized as minimum as 0.1mm, and the maximum feeding thickness is 12mm. As for the wire, it can be between 14-0.8mm, and the size customization is accepted.

How to Use a Double Head Rolling Mill: Step-by-Step Guide
Step 1：Early Inspection
- Ensure that the workbench is clean and no other debris, and check whether the protective device buttons can be used normally.
- Check whether the processing material can be used, such as determining what metal it is and measuring the thickness and width of the material to be processed. Avoid machine damage due to the use of unsuitable materials.
- Check whether the oil level of the fuel tank reaches the standard position, and add it in time when there is no oil to ensure the normal operation of the automatic refueling function.
- Turn on the machine and let the machine run for two laps, check the condition of the rollers, whether there is damage or stains, to avoid waste of materials.
Step 2：Runtime Considerations
- After the inspection is completed, the power can be turned on, and the material can be placed close to the working area of the rolling mill.
- During the rolling process, the screws on both sides can be turned to adjust the distance between the two rollers, and the screws are controlled by the gear on the top of the machine. so turning the gear plate on the top can realize the adjustment of the roller crimp.
- When adjusting the seam every time, avoid too tight adjustment at one time, which will easily cause damage to the machine. The operation should be repeated several times until the desired thickness appears.
- The pressure roller of the electric rolling mill rotates relatively fast, so when putting in the material, you should quickly withdraw your hand to avoid being crushed by the opposite roller.
Step 3：Post-maintenance
- After the rolling work is finished, turn off the power in time.
- The most important part of the rolling mill is the counter roll, so it must be well maintained. It should be noted that a machine with a horsepower of more than 10p should be selected for extremely hard materials, otherwise it is easy to cause pits or indentations on the rollers, which will affect the quality of the finished product.
- When the pressure roller is damaged, please hand it over to a professional for repair.
- The coolant needs to be checked regularly, and replenished in time when it is lacking.
- The machine should be installed in a place without shock source, sunlight and radiation. Keep dry, away from moisture or drafts.
- Regularly check the electrical box to see if the components inside are abnormal.
Double Head Rolling Mill vs Single Head Rolling Mill: Key Differences
Production Requirements
The most intuitive difference between ordinary and double head rolling mills is the number of machine press rolls. Double head rolling mills are more suitable for factories with large output requirements. Whether you are a professional sheet maker or wire maker, its output is twice the output of the same horsepower.
For some factories with a wide variety of jewelry production styles, the double-head rolling mill is also very practical, because two pressure rollers can be reasonably used, the sheet and wire pressure can be combined to work at the same time. However, ordinary rolling mills can only achieve these under one roll, and the efficiency will be lower, so the output will be lower.
Various Finished Products
The double-headed rolling mill is more flexible, and the display of the finished product can be diversified. For example, when you need the finished product to have a smooth mirror effect, you can customize the tungsten steel pressing roller.
With the use of the double-headed design, even if you need to press the metal or the finished product various effects, all of which can be easily realized on one machine
Production Speed
Many electric rolling mills have a fixed speed, which makes it difficult to rationally allocate resources, resulting in an inability to increase the production speed.
The double head rolling mill uses frequency conversion to adjust the speed, and the adjustment range on both sides is 0-22 rpm. The speed can be adjusted according to the number of production personnel or production needs, so as to achieve more efficient resource allocation and thus increase production speed.

1. What is a double head rolling mill used for in jewelry making?
A double head rolling mill is designed to roll both metal sheet and wire simultaneously using two separate roller sets in one machine. In jewelry manufacturing, it is widely used to flatten gold, silver, copper, and platinum into uniform sheets for rings, bracelets, and pendants, or to reduce wire diameter for chains and prongs. The dual-head design eliminates the need to switch between two separate machines, significantly improving production efficiency.
2. What is the difference between a rolling mill and a wire drawing machine?
A rolling mill uses two rotating rollers to compress and flatten metal, reducing its thickness while increasing its length. It can process both flat sheet and wire profiles. A wire drawing machine, by contrast, pulls wire through a series of dies to reduce diameter — it only works on round wire and cannot produce flat sheet. For jewelry workshops that need both sheet and wire output, a double head rolling mill is the more versatile and cost-effective choice.
3. Can the SuperbMelt double head rolling mill process platinum?
Yes. The SuperbMelt double head rolling mill is compatible with platinum, gold, silver, copper, palladium, and most precious and semi-precious metals commonly used in jewelry production. The rollers are made from high-grade hardened steel to withstand the hardness of platinum without deforming. For best results with platinum, we recommend starting with a thicker gauge and reducing in multiple passes.
4. What is the minimum thickness this rolling mill can achieve?
The SuperbMelt double head rolling mill can roll sheet metal down to a minimum thickness of 0.1mm, making it suitable for producing ultra-thin decorative inlays and foil-like components. Wire roller output ranges from 0.8mm to 14mm in diameter, covering most standard jewelry wire gauges.
5. How long is the warranty and what after-sales support is available?
SuperbMelt provides a standard 2-year warranty on all rolling mills, covering manufacturing defects and mechanical components.

8. What is the difference between a manual and an electric rolling mill?
A manual rolling mill requires the operator to turn a hand crank to feed metal through the rollers, which demands more physical effort and makes it difficult to maintain consistent rolling speed. An electric rolling mill automates the feed process with a motor-driven system, delivering more uniform pressure, higher output speed, and significantly reduced operator fatigue. For commercial or high-volume jewelry production, an electric double head rolling mill is strongly recommended.
9. Does the rolling mill require any special installation or electrical setup?
No special installation is required. The SuperbMelt double head rolling mill is a plug-and-play machine that comes fully assembled. It operates on standard 110V or 220V power supply depending on your region. The machine can be placed directly on a workbench with adequate load-bearing capacity. No foundation work, ventilation systems, or specialist technicians are needed for basic setup.
10. How do I maintain the rollers to extend the machine's lifespan?
To keep the rollers in optimal condition, clean the roller surface with a dry cloth after each use to remove metal debris and dust. Apply a thin layer of machine oil to the rollers and gear components weekly to prevent rust and reduce mechanical wear. Avoid rolling hardened steel or abrasive materials, as these can scratch the roller surface. With proper maintenance, the SuperbMelt rolling mill rollers typically last 5–8 years under regular production use.
