The Export Condition about the Mining Equipment

<p>When the rotating speed of ball mill exceeds a certain speed (with much higher speed), the steel ball will rotate with the barrel and won&rsquo;t fall down, in a condition of centrifugal movement. There is no impact force, so the grinding function is much less, and the ball mill stop grinding. The ball mill rotating speed is called critical speed when the outmost layer balls just rotate with the barrel and don&rsquo;t fall.</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete mixer,<a href="http://www.doubleshaftconcretemixer.com/beltplant/hzs60-belt-conveyor-type-concrete-mixing-plant.html">concrete batching plant</a>s,concrete mixer,blocking making machine,concrete pump,etc. <p> <p>The critical speed of various ball mills is in direct proportion with its diameter <a href="http://www.daswellmachinery.com/product/Concrete_Batching_Plant/20130927/19.html">Stationary Concrete Batch Plant</a>, the absolute figure of critical speed is hard to calculated, and now only the calculation formula on critical speed in theory is widely used. When the non-smooth lining plate is used, the filing ratio of ball load is among 40%~50%. When the ore-grinding concentration is larger, the grinding effect is close to the practical production.</p>
