INVT GD880 VFD for Aluminum Kneader Application

1. Background of the project

From bauxite to aluminum is a long and highly technical process, and the kneader is one of the key equipment.In the past, the related driving equipment has been monopolized by foreign brands for a long time in China, but with the continuous improvement of technology and service level of domestic brands, localization substitution has now become a major trend.

2. Customer demand

In Lanzhou China, an aluminum company, the customer original use of the international big brand VFD age has been long, the service life of the basic reached the limit, so the demand for optimization of the VFD update, its requirements of the new VFD:

2.1 Must be in the original process production system does not do under the premise of transformation, completely replace the original product.

2.2 The production of instantaneous torque, fast response speed, power changes smoothly, small rate of change, to protect the production quality of the kneader is stable.

2.3 The accuracy of the feedback speed and the given speed is less than 1 revolution, for example, when there is a large piece of asphalt, the frequency converter can output a large torque in a short period of time to mix it evenly with other materials, while the current and power changes are small, and won't trigger the system to protect the shutdown.

3. INVT Solution
In response to customer needs, INVT provides GD880 series engineering drive VFD.

Based on the continuation of the high reliability of GD800, GD880 series engineering drive VFD is characterized by excellent speed and torque control performance, modular design, long-life device selection, free programming function, etc., which satisfy the customer's needs in terms of delivery cycle, price, maintenance and production stability.

4. Customer Beneifts

* Reliability: Since the electrolysis process requires a continuous, uninterrupted supply of carbon anodes to the production process at all times, the reliability and stability of the kneader drive is of paramount importance. Therefore, the reliability and stability of the kneader drive is crucial. GD880 series products have an average trouble-free time of up to 80,000 hours, high reliability has been verified in a large number of sites, to ensure the stable operation of the equipment, to ensure the production of key raw materials to protect the customer's problems, reduce labor maintenance and equipment costs.

* Performance: excellent performance, the key technical indicators can be comparable to imported leading brands, to achieve the perfect solution for localization substitution. On the basis of maintaining the original production capacity of 28 tons per hour, the output is increased to 30 tons per hour.

* After-sales service: INVT provides 7*24 hours after-sales service, and can guarantee to arrive at the scene to solve the problem in 24 hours.
Ending

The successful application of INVT GD880 series of engineering drive VFD in kneaders has strongly impacted the long-term monopoly of foreign brands on the kneader drive market, and set an outstanding milestone for domestic VFD brands.

At present, INVT can provide complete system solutions in all segments of the non-ferrous industry, and has accumulated a large number of successful cases. Through its advanced technology, it has helped global non-ferrous enterprises significantly improve the energy-saving level of load equipment, significantly reduce production and maintenance costs, and greatly enhance the degree of automated operation and production efficiency. In the future, INVT will create high-quality solutions for more enterprises, and join hands with all parties to promote the continuous progress and development of the industry.
