When Do Impact And Attrition Occur If Crushing Process

To maximize crushing, you must marry impact and attrition actions.When size reduction begins, the material is picked up by the lower liner, moved outwardly and caught between the crushing members.The impact of the head results in reduction of material by grinding and by facture of particle-upon-particle caused by forceful relocation to the particles within the mass.Even at the closest approach of the attrition members, the liners are still separated by a layer of small particles of substantial thickness.In most instances it has been found that a better product and greater usable quantity of desired size is obtained by increase rather than decrease of gap when it becomes a question of optimizing crusher capacity and power draw.Therefore, the setting of the crushing members is not as directly related to the size of the product required as is the setting in the cone-type crusher.Remember that during the upward thrust of the rotating head two distinct processes combine to reduce the feed into a uniform fine product: 1.The impact of coarse particle against fine particle similar to the action of balls or pebbles in a grinding mill.The progressive structuring of cubical shaped, fine, particles is clearly shown in these two enlarged views of the attrition zone.Finely crushed particles are discharged at perimeter of attrition chamber.2.The attrition resulting from the high surface friction during forceful relocation of the particles into smaller voids within the feed mass.In the gyradisc crusher, the combination of impact and attrition offers the most efficient power utilization as compared to other fine crushing or reduction methods employed today.Hongxing company lays much emphasis on the quality and clients.We serve clients with the quality guideline of being responsible for every working procedure, every product and every client.What we have done is for the clients and we believe that quality is the best way to develop market.All of the products have passed the authentication of iso9001.Hongxing brand is the chinese famous brand.Reliable and stable quality is the key to success.Our products are well known at home and abroad.Now we have tens of thousands of users throughout china and more than 30 world markets.As the professional manufacturer of complete sets of mining machinery, such as magnetic separator,cement mill,vibrating screen,dryer machine,classifiers, henan hongxing is always doing the best in products and service.Cement production line: http://www.Hxjqchina.Com/n27.Htmlchina cone crusher: http://www.Crusher-machine.Com/4.Htmlartificial sand maker: http://www.Crusher-machine.Com/18.Html.
