Double Head Rolling Machine

China Professional Electric Jewelry Rolling Mill Supplier

jewelry electric rolling mill

The double-head rolling mill is used for the production of gold, silver, copper, platinum and other jewelry sheets or wire. It can simultaneously realize the pressing of sheets and wires. Later, it can complete bangles, rings and chain with the use of hollow tube welding  machines, bangle forming machines, wire drawing machines and chain making machines.  Double heads design work more efficiently and can easily achieve mass production.

At present, there are more manual rolling mills on the market, the efficiency is very low, and the finished products are rough. For some large jewelry manufacturers, it is particularly important to choose a jewelry rolling mill that is efficient and can easily realize mass production. The SuperbMelt double-head rolling machine is more suitable for jewelry making factories with medium scale or scarce personnel because it can acheives one machine can be used for multiple purposes, saving time and manpower.

    Chapter 1:

    SuperbMelt What Kind of Products can be Pressed?

    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.


    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.


    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.


    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.

    Finished Products

    Jewelry rolling mill is a machine commonly used by jewelry manufacturers. With the use of other jewelry equipment, the final product can be made into hollow bracelets, rings, bracelets, necklaces, etc. It is also a more efficient rapid prototyping tool for metal sheet and wire for the metalworking industry.

    Operating Process and Precautions

    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.

    What is The Difference between Double Head Rolling Machine and Ordinary Electric Rolling Mill?

    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.
