C Highhelix twist drills Highhelix twist drills are designed for drilling deep holes in aluminum copper diecast material and other metals where the chips have a tendency to jam in a hole. The high helix angle 35 to 45 and the wider flutes of these drills assist in clearing chips from the hole but weaken the drill body.

Variables that Affect Weld Penetration
An E70T1 electrode typically has deeper penetration while an E71T1 electrode typically has shallower penetration. Travel Angle: the degree of the travel angle whether a push or drag travel angle affects how much of the arc force is directed down into the base plate.
AMIT 145: Lesson 4 Gravity Separation Mining Mill Operator
Centrifugal Force F c When the particle size falls below 1 mm the rate of separation significantly impacts efficiency. To allow density based separations a centrifugal field is applied by either a mechanical action or by accelerating the particles around a rotational axis.

The Lorentz force on a charged particle has a component along z given by Fz qv Br 3.320 where the azimuthal particle velocity averaged over a LWPCradius r rL gyration is v v . The average force on the particle is then F z 1 2 mv 2 B Bz z. 3.321 The magnetic moment of the gyrating particle is defined as

Air Classifiers Sturtevant Inc.
Sturtevant air classifiers balance the physical principles of centrifugal force drag force and gravity to generate a highprecision method of classifying particles according to size or density. All three Sturtevant air classifiers offer durable construction as well as time and energysaving advantages.
