80L working volume falling type rubber banbury mixer adopts
automatic batching system
- Introduction to the Falling - type Rubber Banbury Mixer
- The falling - type rubber Banbury mixer is a kind of advanced
rubber mixing equipment. It is designed to mix rubber compounds
with various additives such as fillers, accelerators, and
antioxidants to achieve a homogeneous mixture.
- The "falling - type" feature usually refers to the way the ram or
the upper part of the mixer operates. It can move in a downward
motion during the mixing process to apply pressure on the materials
inside the mixing chamber.
- Working Principle
- Mixing Chamber and Rotors: The mixer has a closed - loop mixing chamber where two rotors
rotate in opposite directions. The rotors have a special shape with
helical lobes. As the rotors turn, they cut, shear, and knead the
rubber materials. The relative motion of the rotors creates a
complex flow pattern of the rubber mass, which helps in the
dispersion of additives and the breakdown of rubber agglomerates.
- Pressure Application: The falling ram exerts a downward force on the material. This
pressure is crucial as it helps in improving the mixing efficiency.
It forces the rubber and additives to be in closer contact and
enhances the shearing action of the rotors. The combination of the
rotor movement and the pressure results in better dispersion of
fillers and chemicals into the rubber matrix.
- Components and Structure
- Mixing Chamber:
- The mixing chamber is usually made of high - strength steel with a
special internal surface treatment to prevent the rubber from
sticking. It is designed to withstand high pressures and
temperatures during the mixing process.
- The chamber may have a jacketed structure for temperature control.
Coolant or heating medium can be circulated through the jacket to
maintain the desired temperature of the rubber mixture.
- Rotors:
- The rotors are the heart of the mixer. They are made of alloy steel
with high - strength and wear - resistance characteristics. The
shape of the rotors, including the angle and shape of the lobes, is
carefully designed to optimize the mixing effect.
- There are different rotor designs available, such as tangential and
intermeshing rotors. Tangential rotors have a more shearing -
dominant mixing action, while intermeshing rotors provide better
material turnover and mixing uniformity.
- Ram and Pressure System:
- The ram is responsible for applying the downward pressure. It is
usually actuated by a hydraulic or pneumatic system. The pressure
can be adjusted according to the specific requirements of the
rubber mixture and the mixing process.
- The pressure system also includes pressure sensors and control
valves to ensure the accurate and stable application of pressure.
- Advantages
- High - quality Mixing: The combination of the falling - type pressure and the rotor
action results in excellent dispersion of additives in the rubber,
producing a high - quality rubber compound with consistent
properties.
- Efficient Mixing Process: It can significantly reduce the mixing time compared to
traditional open - mill mixing. The closed - chamber design also
reduces the loss of volatile additives and improves the overall
efficiency of the mixing operation.
- Automation and Control: Modern falling - type rubber Banbury mixers are often equipped
with advanced automation and control systems. These systems can
precisely control parameters such as mixing time, rotor speed, and
pressure, enabling consistent and repeatable mixing results.
- Applications
- The falling - type rubber Banbury mixer is widely used in the
rubber - manufacturing industry. It is suitable for the production
of various rubber products such as tires, conveyor belts, rubber
hoses, and sealing products. In the tire - manufacturing process,
for example, it is used to mix the rubber compound for the tread,
sidewall, and carcass, ensuring the excellent performance and
durability of the tires.
