Gravity destoner is based on the proportion of different food grain and gravel and suspension speed, the grain size and grain shape approximate grain sand and other debris separated from the machine.
Gravity destoner to stone with a good effect, simple structure, small size and low power consumption advantages. The proportion of food through a machine to clean up the stone, rock removal rate of more than 95%, in addition to brick, mud rate greater than 60%, and less loss of food grains to clear gravel containing full grain grains not more than 100 / kg.It works by means of vibrational motion, adjusting the air flow and adjust the inclination of the screen surface to separate food and gravel. Food is shot by the body size and proportion of different particles, when subjected to vibration or motion in a certain state, a variety of different particles according to their specific gravity, particle size, shape and surface state and is divided into different levels.
When Gravity destoner work, the 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 of the role screen surface, so that the porosity between the particles increases, the material in a fluidized state promote the automatic classification, heavy stones and sank the bottom of the screen surface in contact, a small proportion of food floating to the top, under gravity, inertial force and the continuous feed, driven down to net grain exports; rather than the major stones under the influence of the screen surface vibration system inertia force and air flow relative to the screen surface slippery stone, poly-stone towards the area Featured area. Featured Featured room area by the introduction of an airflow fan. Blowback square in front of the screen along an arcuate path, a small amount of food grain stones contained in polyethylene blown back stone area to avoid discharge together with stones. Type manner by using a jet into the suction blowing two. Proportion to stone-blowing from the feed means to stone screen surface, part of the gas flow system and drive mechanism, etc. Sieve and fan housing is fixedly connected integrally with the boom hanging on a rack driven by the eccentric drive mechanism reciprocate. Stoner is an associative face punched rows of scale-shaped mesh sheet steel. Depending on the action, divided into separate, poly stone and a selection of three zones. Scale mesh-sided and single-sided convex protrusions are two types of small mesh opening, grain by grain not only the air flow in a certain direction, and prevents stones fell.
