04 Dec 08 How Screening Machine Works?
In screen grading, the material is separated mechanically on screen plates. Rolling bearings in vibrating screens are stressed by high, mostly shock-type loads. Moreover, the bearings, while rotating about their own axis, perform a circular, elliptical or linear vibrating motion. This results in high radial accelerations which additionally stress the bearings, and especially the cages, considerably. The operating speeds are usually very high. As a result, the bearing temperatures are up to 20 to 30 degrees Kelvi... Full articleTags: screening, screening machine, screening machine principle, separation, working principle
04 Dec 08 How VSI Crusher Works?
The stuffs, which fall into the high-speed rotating impeller from the upper of the VSI crusher, were stroked with other stuffs, which more around the impeller, because of high-speed centrifugal force .After they strike mutually, whirling fluid is produced between the impeller and outer covering .Through repeatedly striking and rubbing, the stuffs are crushed into pieces and straightly come out of the lower. The operating process circulates repeatedly. And then attains the fineness of the product. >>>Wo... Full articleTags: crusher, sand making mchine, VSI crusher
04 Dec 08 How Roller Mill Works?
Feed the stuff evenly and continuously into the grinding chamber. Due to the centrifugal force in rotation, the roller swings outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded. After being grinded, the stuff is to be routed to the sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the product cyclone collector toge... Full articleTags: grinding, grinding machines, mill, roller mill, working principle
20 Nov 08 How Ball Mill Works?
A ball mill operates by rotating a cylinder with steel grinding balls as media, for the ball to fall back into the cylinder and onto the material to the ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter is, the slower the rotation will be. If the peripheral of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. >>>Working Principle of othe...

20 Nov 08 How Cone Crusher Works?
Cone crusher is suitable for crushing various mid-hard and above mid-hard ores and rocks. It has the advantages of reliable construction, high prod activity, easy adjustment and less cost in operation. The spring release system of cone crusher acts an overload protection system that allows tramp to pass through the crushing chamber without damage to cone crusher. Two kinds of sealed formation dry oil and water are used, the plaster stone and engine oil are separated, and reliable performance is ensured. >>...
