  • ZKD/ZXD equal-thick (banana) vibrating screen

Use:

ZKD/ZXD series equal-thick (banana)vibrating screen is a new screening machine developed by zhenyuan machinery based on advanced technologies both at home and aborad. It can be drive the exciter to make reverse self-synchronization run using the universal coupling connected by two motors. Compared with linear vibrating screen and circular vibrating screen with same specification ,the screen has the advantages of higher screening efficiency and larger capacity .It is suitable for raw coal dewatering and medium draining and other lump materials screening. Therefor ,the screen has been widely used in industry of coal ,metallurgy and mine, etc.

Working principle:

ZKD/ZXD series equal-thick (banana)vibrating screen  is driven by two shafts adopting the principle of self-synchronous vibration. Screen deck is composed of many screen plateds with differents slope angles, and formed banana shape in cross-section so that ensure material thickness os every screen deck shall be approximately equal at inlet,which makes the screen improve screening effiency. During operation period, materials move fast at the head setion in order to feed evenly and rapidly ,and bed of materials become thin because of penetrating reaching secondary section, but they obliquity reduce and moving speed slows dwon to get invariable thickness of materials, which gets same use ratio for the whole screen deck, thus obtaining larger capacity, the screen is 1-2 times as capacity as common vibrating screen ,moreover it is suitable for dry and wet classification of middle and fine materials.

Structure features:

ZKD/ZXD equal-thick (banana) vibrating screen mainly consists of screen box,vibration reduction spring, exciter as well as spring support, coupling,electromotor and bracket. The screen box is composed of screen frame, screen plate and fixing device.

Exciter is installed on big beam on the top of screen box, and connected by high-tensile bolt and self-locking nuts.

Electromotor is mounted on the fixing bracket and connected with the universal coupling and exciter. The sieve plate may be classified into woven screen mesh and polyamine screen plate, etc. according to the different physical propertyies of material.
