Functional Principle In the DM 200 the feed material enters the dustproof chamber from the filling hopper and is fed centrally between two vertical grinding discs A moving grinding disc rotates against a fixed one and draws in the feed material The necessary comminution effects are generated by pressure and frictional forces
principle paper is made by 1 pulping to separate and clean the fibers 2 beating and refining the fibers 3 diluting to form a thin fiber slurry suspended in solution 4 forming a web of fibers on a thin screen 5 pressing the web to increase the density of the material 6 drying to remove the remaining moisture and 7 finishing to provide a suitable surface for the intended end
Now the tire building can begin The various semi finished products come together on the tire building machine and are assembled into what is known as a green tire This is done in two stages the casing and the tread/belt assembly This green tire is then sprayed with a special fluid to prepare it for vulcanization
