  • 2.3.1 Coefficient of Friction

    But in a fixed-speed, horizontal conveyor, tension is decided by those factors shown below: The coefficient of friction between the chain and the rail when conveyed objects are placed on the chain. The coefficient of friction between conveyed objects and the rail when conveyed objects are held on the rail and pushed by the chain. NOTE: There are two types of tension: the first occurs when

  • Bulk solid stability on inclined belt conveyors

    In this, preliminary testing using two coals, two rubber belts and several different operational conditions were used, such as loads and moisture content. The experimental results confirm that both static and kinetic angles of friction between the belts surfaces and the coals tested are considerable higher than the presently recommended maximum inclination angle for belt conveyors.

  • Fire Protection Requirement for Conveyor Belts

    21.10.2018· Conveyors are made of stainless steel frames with plastic wear strips and plastic chains (low friction acetal). We have provided Fire protection system at the ceiling level (11.1 Mtrs. High) in the factory process area where the filling and packaging machines/conveyors are present. The level of conveyor belts from ground is about 1.5-2 Mtrs. I had a doubt, is there a separate requirement for

  • Load Analysis of Trestle Leg Conveyor Support

    In other cases, particularly in the coal industry, the load-out conveyor is supported on trestle legs which are substantially buried in the stockpile as illustrated in Fig. 1. It is this system that is the subject of this paper. The paper builds upon the work of Roberts et al [1-3] which dealt with buried structural members which are square or rectangular in cross-section. In this current

    Application on conveyor belt and coal transport trestle. According to actual situation, there are 2 options: Plan A. If the width of conveyor belt is less than 0.4m, protect it with an equal length of optical fiber sensor cable. Optical fiber cable can be fixed directly on the appendant right above the centre of the conveyor belt less than 2.25m. The appendant can be a supporting wire or original fixture. Supporting

    Conveyor belt tracking problems can occur even on the most modern and sophisticated systems. At the Newcastle Coal Infrastructure Group (NCIG) terminal in Newcastle, NSW, Australia, some 167 kilometres north of Sydney, belt tracking issues generally occur because of a lack of friction between the belt and the aluminum idlers.

  • Fire-protection guidelines for: Conveyors transporting coal

    roller, or the friction between a seized roller and the belt, will result in a build up of heat which can be sufficient to ignite the belt, when the belt stops. The introduction of coal makes a fire highly probable. Many different types of fire detector have been tried for conveyors. These attempts, some going back many years, include:- ♦ Collective reflectors (thermo-couple hoods

  • Wire Rope Sheave Friction Effects - ppi-global

    Wire Rope Sheave Friction Effects on the Takeup Carriage Belt Tension by: Jeff Poe Mechanical Engineer, Precision Pulley, Inc., Pella Iowa ABSTRACT When a takeup weight is offset to the side of a conveyor, a wire rope is commonly routed from the take-up weight through a series of sheaves to the take-up carriage. The friction developed from a series of wire rope sheaves can effect the actual
