The ball mill is mainly used to grind materials in mineral‚ cement‚ refractory‚ chemical industry‚ etc. Ball Mill has dry and wet ways. When wet Ball Mill works‚ certain water and other liquid will be added into materials to increase flowability of materials‚ so the capacity is increased. When dry Ball Mill works‚ capacity is affected because material flowability is reduced‚ so absorbing wind device is needed on the outlet of Ball Mill‚ and then negative pressure is formed in the Ball Mill to increase

"Her First Ball" is a title which itself suggests anticipation‚ excitement‚ fun; it is all that and more for Leila. Through the absent narrative‚ she is presented to us as a simple‚ innocent shy country girl who is yet to experience something fun and grand‚ like this ball. In fact‚ this ball itself is used as a metaphor for her own life; her transition from the innocent youth to the mature adult. We see this as the story progresses‚ and through her actions we recognize her thoughts. At the beginning

Name(s)_____________________ HOOKE’S LAW and SIMPLE HARMONIC MOTION INTRODUCTION Any motion that repeats itself in equal intervals of time is called periodic motion. A special form of periodic motion is called Simple Harmonic Motion (SHM). Simple Harmonic Motion is defined as oscillatory motion in which the resultant force on the oscillating body at any instant is directly proportional to its displacement from the rest position and opposite in direction to its motion. For a spring system‚ this can be written
