Various types of material handling technologies are used in the stone crushing industry for the purpose of moving the stones from one equipment to other, right from the point of raw material unloading upto stockpiles of products. Primarily, feeders and conveyors are used in almost all crushers , which are briefly described below.
Feeders
feeder is used for conveying raw, mined stones from the stone well to the Primary Crusher. Feeder movement is controlled by electrically operated switch. Some of the common feeders in use are apron, belt and vibratory type feeders, which are briefly described below.
Apron feeder:
This type consists of uniform overlapping pans attached on to chains or joined by integral links to form an endless conveying medium that travels over supported rollers. The underside of these pans is reinforced to withstand impact and pressure.
Belt feeders:
Belt feeders can handle a wide range of materials including sand, gravel, crushed stone, crushed rock, and other bulk materials.
Vibratory feeders:
This type vibrates at relatively high frequency and small amplitude.
Conveyors
Types of Conveyors are as follows:
Apron conveyor :
This type comprises overlapping beaded metal apron for carrying non granular hot or abrasive materials, horizontally or at inclinations dictated by economy and allowed by flowability. Normally these conveyors are supported and moved by a pair of matched roller chains with the usual head and foot sprockets. To withstand the severe impacts involved when receiving very heavy loads, the aprons may be of shock resistant alloy-steel and slightly under their path at the loading point, rails or other means may be installed to help curb permanent deformations of those that yield under shock.
Belt Conveyor:
Comprising an endless belt operating over idlers, this type is the most widely used conveyor in stone crushers.
Bucket Elevators
Bucket Elevators are used for lifting crushed stone from crusher to the vibratory screen installed at high level well above the storage bins. The bucket elevators arranged in a slight taper angle of about 75 to 80 degrees. These are commonly used where there is space constraint while installing a stone crusher .
