Elasticity' chart, we can assume an average modulus of 1,400 kg/cm2 for LDPE. 1.5% of 1,400 is .015 x 1,400 = 21 kg/cm2 = 0.21 kg/mm2 If our film sheet is 1500mm wide and .05mm thick, then the cross sectional area is 1500mm x .05mm = 75 square mm. Therefore the maximum allowable tension would be: 0.21 kg/mm2 x 75 mm2 = 16 kg Total Web Tension

Drum Mill TM 500. The Drum Mill TM 500 is a laboratory ball mill designed to grind large sample volumes up to 35 l. It accepts initial feed sizes of up to 20 mm and can achieve grind sizes down to 15 µm by friction and impact. Hard, brittle or fibrous samples are pulverized in the 150 l drum filled with 80 kg grinding balls.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

Covered rolls should be at room temperature and rotated slowly for a few hours before grinding. This will allow the cover to stabilize and round out. Roll grinding Grinding restores the original properties and qualities of the cover. Oxidation, blemishes, surface checks, cuts, and cracks are removed by grinding.
