In most plants, moving material from one point to another is left to a conveyor: crushed stone leaving the quarry, cartons entering a warehouse, wheat rising to a silo or bricks le... More Details

A concrete plant has no single main motor; every step from the aggregate bin to the mixer gate is run by a separate drive. A weighing belt measures the aggregate, an inclined charg... More Details

On a farm or in an agricultural plant the electric motor usually works in places nobody looks at: at the head of the bucket elevator that lifts harvested grain to the top of the si... More Details

In a factory or warehouse, moving material usually requires an electric motor. The belt that takes raw material into the plant, the roller line carrying products from station to st... More Details

A plastics plant houses loads that have almost nothing in common under one roof: the extruder screw turns against a steady torque all day, the granulator rotor takes a blow with ev... More Details

In a roll crusher the rock is drawn between two cylinders turning towards each other, squeezed and broken by compression; in single-roll types a toothed cylinder presses the rock a... More Details

In most quarries the machine that takes the large blasted blocks from the truck dump hopper and releases them into the primary crusher at a steady rate is a pan-type (apron) feeder... More Details

Sand, chippings and gravel coming out of crushers and screens wait in separate piles in the open yard until they are sold or shipped. The machine that builds these piles is the sto... More Details

Before a marble, granite or travertine slab becomes a saleable product, it is divided into strips of a set width and pieces of a set length. Two machines share this work: the strip... More Details

Small tiles, mosaic pieces and borders cut from travertine, marble or limestone are put through an antiquing process so that they lose their freshly cut, sharp look and take on the... More Details

The vacuum press is the machine that turns clay from a plastic mass into a shaped column and is regarded as the heart of the brick and roof tile line; we summarised the whole line ... More Details

In ceramic tile, sanitaryware and tableware plants, the body sent to forming is first prepared by grinding clay, kaolin, feldspar and quartz together with water for many hours. The... More Details

Whether it is a small grinder on a butcher's counter or a large screw-fed machine in a meat plant, the force that produces minced meat comes from a single rotating shaft. This page... More Details

In a line that extracts juice from apples, pomegranates, grapes or carrots the press never works alone: first a mill crushes the fruit, then the press squeezes the mash, and then a... More Details

Mixed packaging waste or household waste is tipped into a sorting plant by truck; at the outlet, paper, plastic types, metal and glass have been collected separately. The line that... More Details

A rotary screen, or trommel as it is called on site, is a large inclined cylinder whose shell is made of perforated plate or screen panels. As it turns slowly, the material inside ... More Details

Clay, silt and dust left in sand after crushing and screening are unwanted contaminants in concrete and plaster. The machines that remove them work in water, turning very slowly wh... More Details

A belt conveyor works by an endless rubber or PVC belt, tensioned between two pulleys, running over carrying idlers. The belt carries the material, and what moves the belt is frict... More Details

A screw conveyor pushes powder, granules and fine-grained material with a helical screw turning inside a closed trough or tube. It does not carry the material on top like a belt; t... More Details
