Conveyor rollers are used in roller conveyors and material transport stands to support and move bulky items such as boxes and totes. The rollers let loads roll from one place to another, reducing the effort it takes to move the loads. These rollers can be used to replace or upgrade the existing rollers on compatible conveyors or stands.

These movable bearings are springloaded to provide a safety relief for excessive pressures, such as are caused by tramp iron, etc. They are drawn up against locating shims which establish the spacing between roll faces (discharge setting), and are held in that position by the springs, which are preset to the working pressure for which the particular machine is designed.
ATOX coal mill ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers.

INTRODUCTION TO BOWL MILLS: Coal is the one of the most dominating energy source because of its cost, availability and transportability. Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of lowgrade coals.
Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
