A used compound rubber machine refers to any machine that compounds rubber. Several industrial machines mix rubber compounds. Here are some of the most popular options.
Banbury Mixer
The Banbury mixer is a great used rubber compound machine for mixing bigger batches. It continuously rotates and pushes the material forward using its unique shape. The material is then heaved and fluffed up using the rotating blades. Besides mixing rubber, the Banbury blender is also suitable for mixing other materials like plastics and food.
Internal Mixer
This machine is ideal for mixing small to medium rubber compound batches. Internal mixers have a closed mixing chamber. A rotating drum with paddles is used to mix and knead the rubber. The paddles push the material against the chamber walls, giving the compound an excellent mix.
Open Mixer
An open mixer is suitable for mixing large rubber compounds. It has an open mixing chamber with a flat pan and mixing rollers. An open mixer combines elastic materials by spreading them on a flat surface and working them through two counter-rotating cylinders. An open mixer is energy efficient but takes extra effort to operate manually.
Rubber Kneader
A used rubber kneader machine is suitable for processing rubber compounds with fillers, fibers, and other solid materials. It works by rotating its screws in a heated chamber. The screws move the material forward while turning and folding it, providing excellent mixing and dispersion. This machine can also process other viscous materials like plastics, foams, etc.
Calender
A used rubber calendering machine makes thin rubber sheets with good dispersion firmness. The machine flattens rubber sheets into thin sheets with four to five heavy rotating rollers. The sheets are then passed through a heated chamber, which cures and solidifies the sheets.
Extruder
This machine creates custom rubber profiles, gaskets, and seals. It mixes raw rubber and other compounds and pushes the material through a heated chamber. An extruder can be single-screw, twin-screw, or segmented-screw.
Capacity:
Typically measured in tons or kilograms of rubber mixed per batch. For example, a machine with a capacity of 300 kg can process 300 kilograms of rubber at a time.
Power:
Generally measured in horsepower or kilowatts. For example, a machine with 75 kW power rating means that it consumes 75,000 watts of electricity to run its mixing engine.
Roll diameter:
Usually measured in inches or millimeters. For example, a roller with a diameter of 16'' can represent a 16-inch cylindrical surface.
Roll width:
Usually measured in inches or millimeters. For example, a roll width of 36'' means that the width of the roller is 36 inches, which is large enough to accommodate the wide rubber material.
Temperature control:
It is usually described as a range, such as "The mixing temperature is between 60 and 80 degrees Celsius." This indicates that the mixing temperature is within a specific range to ensure the proper mixing of rubber compounds.
Regular cleaning:
First, the entire machine should be cleaned to prevent the accumulation of rubber residuals and materials. Then, various parts should be cleaned separately, such as mixing barrels, blades, and discharge ports. Also, special cleaning tools and solvents should be used to clean them thoroughly. Besides, the floor of the machine should be cleaned to keep the production environment tidy and safe.
Lubrication:
The lubricating oil and grease used for the used rubber compound machine should be checked first. Then, the key parts such as bearings, gearboxes, etc. should be lubricated. While doing this, the lubricating oil should be evenly coated or injected to ensure smooth operation of moving parts. Regular lubrication can reduce friction and wear, thereby prolonging the service life of the equipment.
Equipment inspection:
Users should regularly inspect the rubber compound machines to ensure that they are in good working conditions. They should check whether the fasteners are loose or not, and whether there is any wear or damage to the parts. If any problems are found, the corresponding repairs or adjustments should be made to avoid potential safety hazards and equipment failures.
