Low price 110kw power composite rubber open mill double roller hardening process longer service life

XK-550 rubber mill has the following advantages:

1. Strong processing capacity:
- Large roller size: The roller diameter is up to 550mm, the working length is long, and it can handle relatively more rubber raw materials. The feeding amount is considerable at one time, and the production capacity is high. It is suitable for large-scale production or scenes with high requirements for processing volume.
- High hardness roller: The roller material is mostly chilled alloy cast iron, and the surface chilled layer hardness can reach 65-70HSD or even higher. The depth of the chilled layer can also meet certain requirements. It is hard and wear-resistant, and can maintain a good working condition for a long time, reducing the frequent replacement or maintenance due to roller wear, and ensuring the continuity and stability of production.
2. Excellent performance:
- Good transmission system: It is usually equipped with a hardened gear reducer. The gears of this reducer are all made of alloy steel hardened teeth. After the gear grinding process, the accuracy can reach 6 levels or above, with high transmission efficiency, low noise, and long service life. It can stably and efficiently transmit the power of the motor to the roller to ensure the normal operation of the roller.
- Accurate distance adjustment device: The distance adjustment range is large, generally adjustable between 0.5-15mm, which can meet the requirements of roller distance for different rubber products. And the distance adjustment accuracy is high. Whether it is manual distance adjustment, electric distance adjustment or hydraulic distance adjustment, the roller distance can be accurately adjusted to control the processing accuracy and quality of rubber.
- Reliable temperature control: The roller temperature adjustment device can effectively adjust and control the working surface temperature of the roller during the rubber mixing process. Some are composed of rotary joints and nozzles, and some can also be equipped with intelligent temperature control systems with high temperature control accuracy. According to different rubber processing requirements, the roller temperature can be accurately controlled to ensure the quality of rubber mixing.
- Effective safety protection: Safety facilities such as emergency stop devices and overload protection devices are equipped. When encountering emergencies, such as accidental injury to the operator or accidental failure of the equipment itself, the emergency stop device can perform emergency braking on the machine to flip the roller and minimize the damage to people and equipment; the overload protection device can automatically stop the equipment when the load is too large to protect the main parts from damage due to excessive load.
3. Easy to operate:
- Flexible operation: Different operation modes can be selected according to user needs, such as manual, electric, etc. Manual operation is suitable for some occasions where the operation accuracy is not high and flexible adjustment is required; electric operation can improve work efficiency, reduce the labor intensity of operators, and the operation is simple and easy to master.
- Easy to maintain: The structural design of the equipment is relatively reasonable, and the layout of each component is compact, which is convenient for daily maintenance. For example, the bearing adopts double-row spherical roller bearings, which are easy to operate and easy to disassemble and replace; the lubrication system adopts manual glycerin pumps, electric dry oil pumps or thin oil lubrication, which is convenient for lubrication and maintenance of key parts such as bearings.
4. Wide applicability: It can be used for various rubber processing processes such as hot refining, mixing, plastic refining of raw rubber and sheeting of rubber materials, which can meet the different needs in the production process of rubber products and is a very practical equipment in the rubber processing industry.

Technical Parameters:

The following are the steps to operate the XK-550 rubber mill:

I. Preparation before starting

1. Check the equipment:
- Check whether the connection of each component is firm, such as rollers, reducers, motors, drive belts, etc., to ensure that there are no loose or damaged parts.
- Check the lubrication system to ensure that there is enough lubricating oil at each lubrication point, such as bearings, gears and other parts.
- Check the electrical system to ensure that the wires are connected normally, there is no damage or short circuit, and the buttons and indicators on the control panel are working properly.
2. Clean the roller: Wipe the surface of the roller with a clean rag or solvent to remove residual rubber, oil and other impurities, and keep the surface of the roller clean.
3. Adjust the roller spacing: Adjust the roller spacing according to the processing requirements. It can be adjusted manually, electrically or hydraulically to ensure that the roller spacing is accurate.

II. Start-up operation

1. Start the power supply: Turn on the power switch and start the motor. When starting the motor, pay attention to the operation of the motor, such as whether there is abnormal noise, vibration, etc.
2. Preheat the roller: Let the roller idle for a while to preheat. The preheating time is generally about 30 minutes, and the specific time can be determined according to the ambient temperature and equipment requirements. During the preheating process, the roller speed can be adjusted appropriately to make the roller surface temperature rise evenly.
3. Adding materials: When the roller surface temperature reaches the process requirements, add the rubber raw materials between the rollers. When adding materials, pay attention to adding materials evenly and avoid adding too much raw materials at one time to avoid overloading the equipment.
4. Adjust the roller spacing and roller speed: According to the processing conditions of the rubber, adjust the roller spacing and speed in time. Generally speaking, during the mixing process, the roller spacing should be gradually reduced and the roller speed should be appropriately increased to improve the mixing effect.

III. Operation during operation

1. Observe the processing conditions: During the operation of the equipment, always observe the processing conditions of the rubber, such as the mixing degree of the rubber, temperature changes, whether there is scorching, etc. If any abnormal situation is found, the machine should be stopped in time for processing.
2. Replenish lubricating oil: Check the lubrication system regularly. If the lubricating oil is insufficient, it should be replenished in time. At the same time, pay attention to the quality of the lubricating oil. If the lubricating oil is found to be deteriorated or contaminated, it should be replaced in time.
3. Clean impurities: During the processing, if impurities or rubber burnt materials are found on the roller surface, the machine should be stopped and cleaned in time. Use special tools when cleaning to avoid damaging the roller surface.

IV. Stop operation

1. Discharge: When the rubber processing is completed, adjust the roller spacing to the maximum and discharge the rubber from between the rollers. Pay attention to safety when discharging to avoid your hands being caught by the rollers.
2. Stop: After the discharge is completed, turn off the motor first, and then turn off the power switch. During the shutdown process, pay attention to the stopping of the equipment to ensure that the equipment stops completely before proceeding to the next step.
3. Clean the equipment: After the shutdown, clean the equipment in time, including the roller surface, feeding port, discharge port and other parts. Use appropriate tools and cleaning agents when cleaning to avoid damaging the surface of the equipment.

V. Precautions

1. Operators must undergo professional training and be familiar with the operation methods and safety precautions of the equipment.
2. During the operation, the operating procedures must be strictly followed, and the equipment parameters and operating methods must not be changed without authorization.
3. During the operation of the equipment, it is strictly forbidden to put your hands or other objects between the rollers to avoid danger.
4. Regularly maintain the equipment, such as changing lubricating oil, checking the electrical system, cleaning the equipment, etc., to ensure the normal operation of the equipment.
5. If the equipment fails, it should be shut down in time and professional maintenance personnel should be notified for repair. The equipment must not be disassembled or repaired without authorization to avoid greater losses.
