In mining equipment, there are many types of feeders. This chapter mainly introduces plate feeders used in combination with open-pit mining, transportation, and crushing. Other types of feeders will be introduced in subsequent chapters.

Summary

Plate feeders are generally divided into three types: light, medium, and heavy. Light plate feeders are suitable for short distance transportation of block materials with a particle size of 160mm or less; The medium-sized plate feeder is an intermittent feeding machine suitable for short distance transportation of block materials with a particle size of less than 400mm; The heavy-duty plate feeder is used for continuous and uniform feeding from the silo to the primary crusher, and can also be used for short distance transportation of materials with larger particle size and specific gravity. For light and heavy-duty feeders, it is relatively simple and there are many factories that can be built. This article will sort out the brands of heavy-duty plate feeders.

Heavy plate feeders are mainly used under silos and funnels to transport various large capacity materials uniformly and continuously over short distances to stage crushing, screening, and transportation equipment, especially suitable for use below primary crushing. It is not only suitable for handling coarse grained materials, but also suitable for fine grained materials. It can complete heavy work in harsh environments and has great adaptability to the particle size, temperature, viscosity, frost, rain and snow effects of materials, or frozen materials. The feeding amount is uniform, and the machine can be installed horizontally or obliquely. The maximum inclination angle for upward transportation is 20 °.

In the practice of mines, crushing stations, as the main supporting facilities of open-pit mines, have grown very fast in the past two decades.

Heavy Plate Feeder

For foreign brands, heavy-duty plate feeders produced by German companies such as O&K and ThyssenKrupp can have a maximum width of 4000mm and a feeding capacity of 6000t/h. The transmission chain is a track chain, and the driving device can be mechanical or hydraulic. The technology that many factories in China first introduced for learning was from O&K Company.

For Chinese brands, Shenyang Mining Machinery Factory (the early name of Northern Heavy Industry) introduced the technology of O&K Company and formed a certain series of products (ZBD type) in the 1990s. In the following 20 to 30 years of development, Northern Heavy Industry made outstanding contributions to the design, research and development, production, promotion and application of heavy plate feeders. However, after 2015, due to its own national physique, it was unable to fully adapt to market competition, In multiple aspects such as sales, design, and after-sales service, Northern Heavy Industries has become increasingly distant from its customers, especially in the 5-6 years before and after being acquired by FangDa, which has been on a downward trend. We hope to regain momentum in the future market.

At present, Beijing BoChuang KaiSheng is a rising star and has made new contributions to the large-scale and intelligent research and application of heavy plate feeders. In 2023, it produced BCZB4000 ×10m heavy-duty plate feeder for a certain mine in Inner Mongolia. It is currently the world's widest heavy-duty plate feeder, and its maximum processing capacity can reach 12000 t/h when applied in coal, mining, and other places.

Some other Chinese companies are also entering the field of heavy plate feeders, hoping to emerge more brands in the future.

Crushing Station

In Brand Collection 3, mobile crushers are introduced. This section mainly introduces large open-pit mining crushing stations, which are usually effectively composed of four modules: feeding module, crusher module, discharge belt conveyor module, and control tower.

Among foreign brands, companies like ThyssenKrupp can design and produce crushers themselves.

For Chinese brands, companies such as Northern Heavy Industry and Taiyuan Heavy Industry can complete the design of crusher stations, but the actual equipment used may be a combination of different brands. In recent years, the design and application examples of BoChuang KaiSheng in crushing stations have been continuously advancing.

BUTTRESS ROOTS will provide the latest brand collection and supply to global mining users.
