The proportion of the working principle of stoner

Depending on the proportion of stoner food grain and gravel gravity and suspension velocity , the grain of the stone side by side ( with the grain of sand grain size and shape approximation ), and other miscellaneous isolated heavy machinery . Ctgrain Destoning Machine has to stone effect, simple structure, small size and low power consumption advantages . After gravity stoner food once cleared, except for stone greater than 95% , in addition to brick, mud rate greater than 60 %, and lost less food grains , clear and full grain sand grains containing no more than 100 / kg. Works With vibration exercise, adjust the airflow and adjust the screen surface inclination to separate grain and gravel . The food is scattered by the particle size and the proportion of mitochondria of different particles, when subjected to vibration or movement in some states , a variety of different particles will follow their proportion, size, shape and surface state and divided into different levels . Specific gravity stoner work , material from the hopper to continue into the middle of the screen surface of the stone . Due to vibration and air flow through the material layer effect screen surface , so that the porosity between the particles increases , the material in a fluidized state promote the automatic grading , heavy stones sank underlying surface contact with the screen , a small proportion of food floating to the top , gravity , inertia and promote continuous feed , fell to a net grain exports ; rather than the major stones vibrating sieve surface under the effect of the inertial force and airflow system relative to the screen surface slippery stone by stone area toward poly selection area. Featured chamber selected areas introduced by the fan airstream . Blowback square in front of the screen along an arcuate path , the stone tablets containing a small amount of grain blowing back POLYROCKS area , along with gravel to avoid discharge . Type by using the airflow is divided into two kinds of suction and blowing . Blowing gravity stoner from the feed device , to stone screen surface , part of the air flow system and the drive mechanism (Figure ) . Sieve and fan housing is fixed integrally connected with the boom hanging on the rack , eccentric drive mechanism driven by the reciprocating movement. Parties to face is a piece of stone rows of scales shaped sieve punched steel sheet according to the different roles , divided into separate , poly stone and a selection of three zones . Sieve has raised scales and double -sided raised two kinds of mesh mouth is small, food grains can not only make a certain direction of air flow and prevent stones decline.
