Coal mining scraper conveyor are widely used, especially indispensable conveyor equipment for large feed mills. Coal mining scraper conveyors include: horizontal scraper conveyor, inclined scraper conveyor, and self-cleaning scraper conveyor. Although the squeegee conveyor looks simple, in actual production, the squeegee conveyor is one of the equipment with the highest frequency of failure, so the correct maintenance and use of coal mining scraper conveyor becomes particularly important.
The composition and structural characteristics of the coal mining scraper conveyor:
Coal mining scraper conveyor are used extensively in feed mills and grain processing plants. It can transport raw materials and finished products horizontally or at an angle. The basic structure of the conveyor is composed of a chain and an upper scraper. It can be designed into various structures, such as multiple inlets, intermediate discharge, and different tilt angles. The design flexibility makes modern scraper conveyor versatile in feed mills. The professional design can make the scraper conveyor run on a steep slope, and has a good self-cleaning function. Some scraper conveyor are equipped with chain break or block protection switches and tail wheel axle speed monitoring.
There are several types of inlets for coal mining scraper conveyor. One is a standard inlet with a simple opening on the top of the scraper conveyor that directly receives material. These inlets require controlled feed, such as with a device or a door, to prevent material blocking. The second type is a bypass or diverting inlet, which guides the material to the scraper conveyor buffer bucket, and then the inlet controls the conveying flow to the scraper conveyor. The thickness of the material is controlled by these inlets, so even if the inlet is blocked, no blockage will occur. There are other ways of feeding.
The coal mining scraper conveyor needs some way to support the chain because the chain comes back from the top of the coal mining scraper conveyor. There are several ways for the chain to return: roller or sprocket. The chain is placed directly on the plastic roller or sprocket. Generally speaking, this method is the most economical. When the chain is not fully tensioned, there is room to sag. But it is not very suitable for wider scrapers, because if the chain is not too tight, the scraper may tilt.
