The belt conveyor is the most commonly used conveying equipment in the coal mining industry. As the core part of the conveyor, the belt is vulnerable to various failures, such as scratches, cracks, wear and tear. Inspection and defect detection is essential for conveyor belts, both in academic research and industrial applications. In …

Abstract: This paper studies the characteristics and design concept of low-speed high-torque direct-driven PMSM with fractional-slot concentrated winding used in coal mine belt conveyor system. The fractional slot concentrated winding PMSM with high efficiency, high power density and simple windings type is used widely, and more attention is paid …

Two new Illinois Basin installations were engineered for high-performance by steve fiscor, editor Successful coal operators know the importance of well-designed conveyor systems. They also know the …

Large foreign object transporting by coal mine conveyor belt may lead to production safety hazards. To reduce safety accidents during coal mining, a large foreign object detection method based on machine vision is proposed in this paper. An adaptive weighted multi-scale Retinex (MSR) image enhancement algorithm is proposed to …

Belt conveyor is a crucial equipment during the coal mining- and transportation-operation process. Foreign objects, like large gangue, anchor rods, once mixed into the belt, can lead to the belt's damage and will thereby cause safety problems in mines. Since the belt is working in a bad illumination and a rather high-speed condition, accurately detecting …

Figure 2 shows a view of the face fill for solid backfill mining. This includes hydraulic support, scraper conveyors, throwing machines and their supporting equipment systems. The hydraulic ...

BSFH 520 Braking System Mining & Aggregate SOBO Brake Control. Syntron Material Handling, a leading mine conveyor OEM, needed a complete braking system for use on two downhill longwall panel conveyors at the Deserado Coal Mine located near Rangely, Colorado. Each conveyor is approximately 14,500 ft. long with 725 ft. of drop from tail to …

In the process of coal mining, a conveyor belt control system also needs to be closely integrated with modern industrial systems and information systems, which greatly improves its work efficiency. ...

While the effectiveness of conveyor belts can be taken for granted, ineffective belts can severely undermine productivity at mine sites. The World Coal Association estimates that over 7,200 million tonnes of hard coal are produced worldwide, all of which will need transporting around mining operations, either for processing or …

The control strategy and algorithm adjust the running speed of the belt conveyor accurately according to changes in the material flow rate, thus reducing damage of frequent speed regulation to the belt …
