Coal mine belt conveyor control system based on load detectio

Gong-kuang zidonghua, 2018
For problems of high energy consumption of belt conveyor and inability to adjust control automatically according to actual coal quantity, a coal mine belt conveyor control system based on load detection was designed.

Analysis of Transient Belt Stretch for Horizontal and Inclined Belt Conveyor System [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2019
Belt is costliest part of belt conveyor system. Sudden rise in belt tension within transient starting condition, results in belt failure and structure damage. It is difficult to measure these stresses by static calculation method and hence their presence

Research on Audio-Visual Detection Method for Conveyor Belt Longitudinal Tear

IEEE Access, 2019
As a key equipment for production and transportation, conveyor belts are widely used in the coal mining industry. Once the conveyor belt longitudinal tear occurs, it will seriously affect the production and even cause personal injury.

Conveyor-belt clock synchronization [PDF]

Physical Review A, 2004
A protocol for synchronizing distant clocks is proposed that does not rely on the arrival times of the signals which are exchanged, and an optical implementation based on coherent-state pulses is described. This protocol is not limited by any dispersion that may be present in the propagation medium through which the light signals are exchanged ...

Ultrafast Chemical Pre‐Sodiation of Pseudocapacitive CaV8O20 Anodes for High‐Performance Sodium‐Ion Capacitors

Advanced Science, EarlyView.
An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Palmitoyl Acyltransferase Zdhhc17 Promotes Functional Recovery After Spinal Cord Injury by Targeting the Nuclear Transport Factors Kpna2 and Ipo9

Advanced Science, EarlyView.
In this study, we demonstrate that Zdhhc17, acting as a PAT, suppresses neuronal apoptosis and promotes axon regeneration after injury, thereby enhancing functional recovery following SCI. In this context, Kpna2 and Ipo9 serve as novel palmitoylation substrates of Zdhhc17, whose palmitoylation prevents the injury‐induced degradation of their proteins ...

Research on Deviation Detection of Belt Conveyor Based on Inspection Robot and Deep Learning

Complexity, 2021
The deviation of the conveyor belt is a common failure that affects the safe operation of the belt conveyor. In this paper, a deviation detection method of the belt conveyor based on inspection robot and deep learning is proposed to detect the deviation ...

Weather Attention in Online Discourse and Price Uncertainty in Agricultural Futures Markets

Agribusiness, EarlyView.
ABSTRACT Weather is a central determinant of production risk in agricultural markets, but markets respond not only to weather conditions themselves, but also to how those conditions are noticed, framed, and interpreted in public discourse. In this setting, real‐time online weather discussions may shape price uncertainty by influencing how market ...

Starting control method of pipe belt conveyor driven by three motors

Gong-kuang zidonghua, 2019
For working status of pipe belt conveyor driven by two motors at head and one motor at tail, considering viscoelastic mechanics characteristics of conveyor belt, a discrete model for belt and driving drum of pipe belt conveyor was built in AMESim ...

Aspects of Selecting Appropriate Conveyor Belt Strength

Energies, 2021
Breaks in the so-called “continuous” (unspliced) belt sections, and not in the spliced areas, are infrequent but do happen in practice. This article presents some aspects, which may account for such breaks in conveyor belts.
