An apparatus for the transport and storage of proppant has a container with a top wall, a pair of end walls and a pair of side walls. The pair of side walls extend between the pair of end walls. The container has a bottom discharge opening. The container includes a funnel extending from the pair of side walls and from the pair of and walls toward the bottom discharge opening. The funnel has sides extending in an angle of greater than 25° with respect to horizontal. The funnel includes a pair of side plates extending respectively from the pair of side walls toward the bottom discharge opening and a pair of end plates extending respectively from the pair of end walls toward the bottom discharge opening. Each of the side plates and the end plates is formed of a stainless steel material.

A light curing device comprises a conveyor belt and a light source provided above the conveyor belt. A positioning block is provided on at least a portion, which is parallel to a conveying direction of the conveyor belt, of a carrying surface of the conveyor belt, and the positioning block includes a positioning surface which is perpendicular to the carrying surface of the conveyor belt and extends along the conveying direction of the conveyor belt. The positioning surface is configured to position an object to be conveyed.

A conveyor belt is formed by covering a belt core body with a cover rubber. The cover rubber has a fine ridged/grooved structure formed on at least a portion of a surface thereof, and has a surface roughness of 1 μm or more and 12 μm or less, a degree of sharpness of 2 or more and 9 or less, and a specular gloss at an angle of incidence of 60° of 0.1 or more and 10 or less due to the fine ridged/grooved structure. The surface roughness is preferably 2 μm or more and 5 μm or less, and the degree of sharpness is preferably 3 or more and 5 or less, and the specular gloss at an angle of incidence of 60° is preferably 0.1 or more and 3 or less. Such conveyor belt is less likely to have a poor appearance due to bloom.

The bristle brush comprises a support plate (1), a plurality of bristles (2) emerging from one of the surfaces thereof, the distal ends of the bristles (2), the ones further from the support plate (1), defining a support surface intended to receive a piece to be transported and/or cut or handled, wherein the distal ends of the plurality of bristles (2) have a semi-spherical or conical shape ending in a tip. It enables a bristle brush to be provided wherein the distal ends of said bristles have a shape which enables the bristles to move when a cutting blade or any other element comes into contact with them, without damaging them.

The present disclosure concerns a belt conveyor roller wear liner superposable against an outer peripheral surface of a roller cylindrical body, the roller wear liner comprising: a shock-absorbing matrix; and a plurality of inserts, spaced-apart from one another and embedded in the shock-absorbing matrix with external surfaces of the inserts and the shock-absorbing matrix, extending between the inserts, being exposed outwardly, the roller wear liner being substantially ring-shaped. It also concerns a corresponding belt conveyor roller assembly, a corresponding belt conveyor and a corresponding method.
