What Is a Conveyor Feeder?
Plate feeders are generally divided into three types: heavy, medium and light. They are commonly used as feeding equipment in concentrators.
- Plate feeders are generally divided into three types: heavy, medium and light. They are commonly used in ore dressing plants.
- Tensioning device adopts screw tension type
- The tensioning support adopts a steel and bolt connection structure, which has a beautiful appearance and convenient assembly and disassembly. For heavy and super heavy tensioning devices, add a set of springs to cushion the vibration. In addition, there are the following two characteristics: (1) The screw of the tensioning device of the medium and light plate feeder is located above the slide seat and placed under the inverted equilateral angle steel.The screw part can be free from pollution and damage; heavy and Tensioning device for super heavy products, the screw passes through the center of the slide. (2) The tensioning device is divided into two types of standard and heavy structure, and it is serialized and universal with the lower tensioning device of the bucket elevator.
- Head and tail bearings mostly use rolling bearings
- The head bearing seat is not horizontally supported on the frame, but the bearing seat is vertically connected to the frame with four bolts. In this way, on the one hand, the bearing bearing force is consistent with the direction of the working tension, improving the bearing condition of the bearing seat and the connecting bolt, and on the other hand, reducing the space size.
- Using combined sprocket
- The material of the driving sprocket is cast iron or steel, and the rim is made of high wear-resistant hardened steel with replaceable teeth. The gearless rim of the tensioning sprocket is combined and replaceable. This can reduce a lot of maintenance and reduce maintenance costs. In addition, the interchangeable gearless edge can ensure correct and constant contact between the chain and the sprocket, and prevent the tooth surface from being glued.
- Support roller
- The medium and light plate feeder support rollers are external, separated from the traction rollers, and have the following advantages: (1) It is easy to set the guide groove. (2) Reduce traction roller wear. (3) Easy to manufacture. For heavy-duty and super-heavy plate feeders, fixed supporting rollers are arranged on the frame. The rollers and the head and tail bearing seats are lubricated by a centralized oil supply method to ensure that the lubrication is regular and comprehensive.
- Hydraulic coupling
- A hydraulic coupling is installed between the drive motor and the reducer, which can ensure the smooth start of the plate feeder and provide overload protection. A chain drive is used between the reducer and the main shaft, which has a buffering effect, can also make the transmission ratio stable, can transmit high power, and the center distance can be adjusted, which is easy to arrange and install. The drive shaft is equipped with a backstop to prevent reverse rotation of the conveying trough. In addition, for example, Yantai Xinhai Mining Machinery Co., Ltd. is equipped with an automatic meter for the amount of material on the plate feeder, and dust removal devices are installed at the head and tail, which greatly improves the work efficiency and is widely used. In summary, although the newly established standards in China are close to the international advanced standards in terms of feed volume and conveying tank size, etc., how to ensure the performance of the whole machine, and achieve high efficiency, low energy consumption, high reliability, etc. Work hard.

- use
- Plate feeder is a continuous transportation machine widely used in mining, metallurgy, building materials, ports, coal and chemical industrial and mining enterprises. It is mainly used to continuously and uniformly supply and transfer various large weights and abrasive bulk materials from the storage bin or the transfer funnel to the crusher, batching device or transport equipment. It is one of the important and essential equipment in the process of ore and raw material processing and continuous production. [2]
- Most no-load start, basically no overload, occasionally start with rated load, the receiving hopper has a maximum of 70t coal;
Zero-speed start is required, and the speed range is 0 ~ 0.6 m / min. Slow acceleration or deceleration can be controlled manually. The speed is 0.3 ~ 0.5m / min.
The external load is basically stable and the impact is small during stable operation;
The ambient temperature is low and the dust is large. [2]
