Paddle Feeder Discharge Arms - A Study on Performance Characteristics

Performance of paddle feeders is mostly dependent on the correct design of the curved rotating discharge arms or “blades” as they are called. This study is an effort to ascertain the appropriate curvature of the blades which will ensure smooth and non jamming performance with minimum power consumption. Effort is also made to establish a procedure for evaluation of torque, speed, capacity and power.
Introduction
The paddle feeder is a reclaiming equipment, widely used in bulk material handling. Its application is found almost in all sectors, such as mining, power, steel, cement, etc. Precise control and capability to facilitate automation in reclaiming has made it widely acceptable in the industry.
The most important part of the equipment are its discharge arms. There has been continuous effort to improve its performance by the equipment manufacturers and the users as well. In continuation, an effort is made here to identify the appropriate curvature, speciality and the benefits.
