In the entire chain of mine production, the feeding link, as a key node connecting ore storage and deep processing, its operational efficiency directly determines the capacity release and product quality stability of subsequent crushing, grinding and other processes. Pendulum feeders and trough feeders, with their differentiated performance advantages, have become the core equipment in this link, providing indispensable support for the continuous production of mines.
According to industry research, pendulum feeders occupy an important position in small and medium-sized mines due to their flexible adaptability. The equipment drives the pendulum rod to swing periodically through an eccentric shaft, driving the feeding trough to realize reciprocating pushing action, which can evenly transport the ore in the storage bin to downstream equipment. Its significant advantage lies in being compatible with multi - granularity ore processing. Whether it is lumpy raw ore or granular materials, it can achieve stable feeding. At the same time, the feeding amount can be accurately controlled by adjusting the swing frequency, forming a dynamic match with the processing capacity of crushing equipment, so as to ensure the continuous and efficient operation of the crushing process. In addition, the equipment has the characteristics of simple structure and convenient maintenance, so that it can still maintain stable working conditions in complex mine environments with high dust and humidity, and is recognized by small and medium - sized mining enterprises.
Compared with pendulum feeders, trough feeders have become the preferred equipment for large - scale production in large mines due to their large capacity and high stability. It is composed of a feeding trough, a driving system and a regulating device. It realizes continuous feeding by driving the ore inside the trough to move directionally through the driving device. Thanks to the large - volume trough design, the equipment can efficiently handle large - granularity and high - tonnage ore raw materials, with a feeding capacity of hundreds of tons per hour. The stable feeding rate can provide homogenized materials for subsequent crushing and grinding equipment, effectively avoiding problems such as sudden changes in equipment load and excessive product granularity caused by feeding fluctuations. In the intelligent production lines of large mines, trough feeders can realize linkage control with upstream and downstream equipment through regulating devices, accurately matching the capacity requirements of the whole process, and helping to improve the overall production efficiency of mines by more than 30%.
Experts in the mining equipment industry point out that although pendulum and trough feeders have different application scenarios, they form functional complementarity in the feeding link and jointly build an efficient channel for ore transportation. Scientific selection and standardized operation and maintenance of these two types of equipment can not only improve the operation efficiency of the feeding link, but also provide key support for cost reduction and efficiency increase in the whole mine process. With the acceleration of the intelligent upgrading of mining equipment, a new generation of feeders with remote monitoring and automatic speed regulation functions has entered the application stage, and will play a greater role in the construction of green mines in the future.
