A link for a conveyor chain includes a first portion and a second portion laterally spaced apart from the first portion. The first portion includes a first sprocket-engaging pin, and the second portion includes a second sprocket-engaging pin. The first sprocket-engaging pin and the second sprocket-engaging pin protrude laterally away from one another. The first sprocket-engaging pin and the second sprocket-engaging pin may each have an oblong cross-section. At least one retainer can secure a connecting pin against movement relative to at least one of the first portion and the second portion, and each retainer can be positioned substantially within one of the first portion and the second portion.

In some aspects, a conveyor chain includes a first link, a second link, and a coupler link coupled between the first link and the second link. The first link includes a first portion and a second portion, the second portion oriented parallel to and laterally spaced apart from the first portion. The first portion includes a first sprocket-engaging pin protruding laterally, and the second portion includes a second sprocket-engaging pin protruding laterally. The second link includes a first portion and a second portion. The first portion includes a first sprocket-engaging portion protruding laterally, and the second portion includes a second sprocket-engaging portion protruding laterally. A flight bar is positioned adjacent an end of the first sprocket-engaging portion of the first link.

A linkage for moving material from a first end of a conveyor toward a second end of the conveyor includes a first link and a second link. The first link includes a first side edge and a first indicator. The second link includes a second side edge and a second indicator. The second link is coupled to the first link such that the first side edge of the first link overlaps with the second side edge of the second link. Elongation of the first link in the direction of movement causes the first indicator to move relative to the second indicator, and a position of the first indicator relative to the second indicator provides an indication of a wear condition of the first link. In some aspects, a first surface and/or a second surface of one of the links includes a wear indicator representing a surface wear condition.

A drive mechanism for a chain conveyor includes an elongated shaft that extends along an axis and is configured to be driven to rotate by a motor. A sprocket is integrally formed with the shaft. The sprocket includes a plurality of lobes that extend around a perimeter of the shaft. Each lobe is spaced apart from an adjacent lobe by a recessed portion. Each of the recessed portions is configured to receive a drive pin of the chain conveyor.

A method for reducing the turbidity of as-mined sand comprising adding water to the as-mined sand to increase its moisture content to between about 5% and about 40% by weight, mixing the sand and water, piling the wet sand on the ground, allowing the sand to rest for a predetermined period of between about 12 hours and about 3 days, then harvesting less than all of the sand from the pile as reduced turbidity sand.

A cartridge assembly for use in a load zone support includes a shaft that is able to be connected to an idler frame of a belt conveyor system. The cartridge assembly further includes a support plate coupled to the shaft and a wear pad coupled to the support plate.

Mined material is transported within and outside a mine (10) in containers (26) that are fixed. discrete load units. namely containers that define a fixed maximum volume that can be carried in each container. The containers can be carried on or coupled to and then removed from vehicles (16) or other transport options. such as flatbed trucks. flatbed rail carriages or overhead suspension units. The containers can be stored at designated container storage facilities (28) in the mine. The container storage facilities are holding areas for loaded containers at mines until decisions are made to transport the containers to mineral processing plants (30) in the mine or to end-use customers. for example via rail to a shipping port (24).

There is provided a material categorisation and transportation system including a plurality of mine vehicles for transporting material within a mine site from a first location in the form of a blast site to a second location. The system includes a sensing device for actively sensing chemical property characteristics of raw blasted mined material such that the raw material can be categorised into a plurality of material categories based on the sensed characteristics. The system further includes a loading device located at blast site for loading the raw material into a predefined one of the mine vehicles based on material category for transportation to the second location. The system is such that each of the mine vehicles only carries raw material of a predetermined one of the material categories.

An apparatus is provided for improving sand storage at a well site, and a system and method are provided for using the apparatus. The apparatus, which may be referred to as a portable tunnel structure, include a hopper having a perimeter edge and surfaces that are sloped downward and inward to a plurality of hopper outlets, a conveyor system having a conveyor belt disposed below the plurality of hopper outlets, and a support framework including a horizontal base structure for supporting the support framework on a load bearing stratum, horizontal hopper reinforcement beams secured along the outer perimeter edge of the hopper, and outer vertical support beams extending between the horizontal base structure and the horizontal beams.

A vibrating screen feed conveying apparatus for conveying and separating sticky moisture laden bulk solids which are sticky and wet flowing onto a vibrating screening feeder and into a hopper. The apparatus includes a bed on which material is conveyed, a longitudinal counterbalance supported on a plurality of isolation springs, a plurality of inclined drive springs extending between the bed and the longitudinal counterbalance, and a plurality of stabilizers for controlling movement of the drive springs along their central axes. A plurality of vibratory motors, each having rotatable eccentric weights are attached to the rear end of the longitudinal counterbalance. The eccentric weights rotate in phase with one another to vibrate the bed at a vibration frequency.
