For Excellent Screen Result To Choose Proper Mesh Shape

The mesh shape directly influences the effective area of the screen.The effective area, also called effective screen surface, refers to the ratio between the sieve mesh area and the geometric area of the screen surface.The larger the screen effective area is, the more screen meshes there will be on the unit screen surface, and meanwhile the bigger probability of materials passing through the screen mesh there will be.Thus, the production capacity and the screening efficiency will be higher.In the screening operations, the commonly used mesh shapes include round, square and rectangle.The sieve mesh of the perforated screen surface is round, while the woven screen surface is with rectangular hole and square hole.Practice has proved that screen surface with different mesh shapes has different effective screen surface areas, and at the same time the probability of mineral grains passing through the screen mesh is different as well.In general, the rectangular screen mesh has the biggest effective area followed successively by square mesh and round mesh.Therefore, the productive capacity of unit screen surface area becomes smaller according to the above order.One of the rectangular mesh's advantages is that the sieve mesh is difficult for clogging.Finally, the mesh shapes should match the shapes of the materials.Generally speaking, the lump materials should adopt the square hole, while the plate materials should select the rectangular hole.The mesh size and grain size are determined according to the following formula: dmax=ka.The fully-mobile crushing plant can also be called self-propelled crushing plant.In accordance with different moving modes, it can be divided into crawler type, rubber-tyred type and walking type.The flexibility degrees are different for the three types of moving modes.Thus, they have different uses.Generally speaking, the crawler type mobile crushing plant can work in coordination with excavators.However, it is restricted by the heavy machine body, so it has a relatively small processing capacity.Currently, its largest known capacity is 1000t/h.The rubber-tyred type and the walking type can only work under relatively fixed conditions.Unlike the crawler type mobile crushing plant, they can not work in coordination with excavators.However, they have large processing capacity, which can reach up to 2000-3000t/h.Jaw crushers: http://www.Hxjqchina.Com/product-list_30.Htmlmobile crusher: http://www.Hxjq-crusher.Com/10.Htmlsand washer: http://www.Hxjqchina.Com/product-list_29.Html.
