Pellet mixers are widely used in many industries. They are often designed with margins and are usually not fully loaded. Traditional pellet mixers do not have speed regulation or mechanical speed regulation, resulting in large losses, fluctuating operation and low efficiency. FRECON FR500A inverter can accurately control speed and is highly efficient and energy-saving. Adding it to a pellet mixer can solve the problem and save energy to recover the cost.
Pellet mixersare widely used in chemical, pharmaceutical, food and other industries for uniform mixing of materials. It is composed of a mixing container, a mixing device, a transmission device and a support frame. The mixing container is mostly made of stainless steel, which is corrosion-resistant and well sealed. Mixing blades can be installed inside, and heating and cooling functions can be equipped as needed. The mixing device is the core component, including a mixing shaft, blades and a motor, which can fully crush, disperse and mix materials. The transmission device consists of a reducer, a coupling and a motor to provide stable power. The support frame plays a supporting and fixing role. The material is mostly steel structure or cast iron, which can be adjusted according to the environment to ensure stable operation of the equipment.
The working principle of the pellet mixers is to use the torque generated by the rotation of the stirring rod to operate the particles in the mixture. The stirring rod pushes the granular material from the inside of the machine to the edge of the mixing barrel, and at the same time allows the material to flip and slide at different positions, so that the particles are fully mixed in the horizontal and vertical directions. After this series of processes, the materials can finally reach a uniform mixing state, meet the requirements of the corresponding production process for the degree of material mixing, and ensure the smooth progress of production.
Variable frequency control technology is the core of electrical automation control and plays an important role in equipment control. In the field of mixers, its application is an inevitable trend and the core of mixing process control automation. After the mixer adopts this technology, it can flexibly adjust the speed and accurately control it as needed, improve the mixing efficiency and quality, and reduce energy consumption and equipment loss, bringing positive effects.
Energy saving and high efficiency: Set multiple speeds according to material characteristics and cooperate with program operation mode to reduce labor intensity and improve efficiency; use V/F function to automatically adjust the curve to reduce current while ensuring torque to achieve energy saving.
Improve performance: Improve the grid-side power factor to above 0.9, reduce reactive power; achieve stepless speed regulation, adapt to the best working conditions, and reduce mechanical losses and operating costs.
Protective equipment: Soft start of the motor, low current, extended life, reduced impact; comprehensive protection functions, adapt to voltage fluctuations, automatic frequency reduction when overloaded.
Optimize the environment: Improve the level of automation, the electrical transmission equipment can be remotely located, the operation is convenient and safe, and it is easy to monitor real-time data.
The FRECON FR500A inverter has excellent performance, greatly improving the operating stability and safety of traditional mixers and reducing the workload of equipment maintenance. Its customized control system integrates a variety of safety technologies and automatic control functions, providing a full set of electronic control solutions for mixer manufacturers and revitalizing old mixers. After its launch, it has received positive reviews from users, solved the problem of backward electronic control of machinery manufacturers, and brought good benefits.
