A conveyor that consists of a suitably tensioned endless belt made from hard wearing materials and arranged to run over rollers.

A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.

A dynamic compressor in which one ore more impellers accelerate the gas and where the main flow through the impeller is radial.

A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.

A conveyor in which endless chains are used to support slats, apron, pans, buckets, as distinct from the use of single band.

A device compensating for axial or radial movement between two elements that is connected.

A 'device' that is providing diversion of something from an expected course or direction.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

A closed transport device that is a gathering line tied into a trunk line.

A separator intended to remove solids from vapour or liquid.

A trough that is located along the eaves to catch and carry liquid.

A vessel with a conical shape for filling or dosing purposes.

A motor that is intended to generate power by means of high pressure oil.

A system that provides lubricant to rotating or moving items.

A physical object that contains a chamber with several openings.

A positive displacement compressor in which forced reduction of gas volume takes place by the movement of a displacing element in a cylinder or enclosure.

A conveyor comprising a series of closely spaced rollers set so that their crests can support articles to be conveyed. They may be power-driven, or freely revolving. Tapered rollers are used to form bends in the conveyor line.

A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.

A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.

Is a conveyer intended to move dry, solid material from one location to another by means of a helix or screw rotating in a cylindrical conduit.

A vibrating screen for sifting out rock cuttings from drilling mud.

A conveyor consisting of a series of slats generally made of metal or wood attached to an endless chain.

A well drilling system and an artefact in which the motor which turns the drill string is connected to the upper end of the string and moves downwardly with the drill string during the drilling operation.
