c) the wider the sieve is, the easier the pipe beam will break. according to experience, when the sieve width exceeds 3 m, it is better to use double channels. d) if the fracture of the pipe beam is not serious, in order not to affect production, the pipe beam can be repaired to continue to use..transportation engineering lab manual,mounted on stub shafts in such a way that it rotates about horizontal axis at 30-33 rpm. instructional capabilities: used for los angeles abrasion test on aggregate. coarse sieve shaker: it is used to sieve the coarse aggregates. it has 3”, 1.5”, 1”, ¾”, ½”, 3/8”, 4.75mm sieve sizes. specific gravity apparatus:.foundations for vibrating machines,horizontal displacement basket housing. table 2. general machinery – vibration severity criteria (baxter and bernhart, 1967) horizontal peak velocity (in/sec) machine operation <0.005 extremely smooth 0.005 -0.010 very smooth 0.010 -0.020 smooth.the design of a pedal driven pulverizing and sieving,2.3 maximum displacement of sieve bed the maximum displacement of the sieve bed from the top dead centre position is given as: l r x 2 sin (1 cos ) t2 t (11) x is the displacement of sieve bed (m), l is the length of the connecting rod (m), r is the crank radius (m), t is the angle of crank with the horizontal (0).
