Rating of Multiple-Ply Belts

 Rating of Multiple-Ply Belts

Multiple-ply belts are now rated on the basis of tensile strength (in pounds-per-inch-width per ply) when the splices are vulcanized. With normal mechanical-fas tener splices, the rating is reduced to approximately three-quarters of the vulcanized values. Some belt man ufacturers can get adequate fastener holding due to their weave, and no reduction in the rating is required.

Sugar Mill Roller Grooves

SUGAR MILL ROLLER GROOVING     The three rolls of a conventional mill are arranged in a triangle so that the fiber is squeezed twice between the top roll and the feed roll and the top roll and the discharge roll. The rolls have cast iron, grooved shells mounted on steel shafts. Fiber passing between the top and feed roll is conducted over a turner plate to the discharge roll. The rolls are pinion driven from the top roll which is driven at a speed of 3 to 6 rpm by a gear reduction system. The feed and discharge rolls are fixed, while the top roll is free to move up and down by means of a hydraulic pressure system. Cane is moved between mills by means of intermediate conveyors. They are generally rake or drag-slat type, which carry the fiber to a fixed chute leading to the next mill. 1)       Circumferential Grooves a)       Cutting grooves around the roll gives a corrugated surface of increased area which has better gripping action because of the compression of

What is ‘pharmaceutics’?

  What is ‘pharmaceutics’? The word ‘ pharmaceutics ’ is used in pharmacy and the pharmaceutical sciences to encompass a wide range of subject areas that are all associated with the steps to which a drug is subjected towards the end of its development. It encompasses the stages that follow on from the discovery or synthesis of the drug, its isolation and purification, and its testing for beneficial pharmacological effects and absence of serious toxicological problems. Put at its simplest – pharmaceutics converts a drug into a medicine.
