Rubber Panels And Plates for NSH Series Screening Equipment

Screening equipment is widely applied in industrial sectors of metallurgy, building material, coal, and road construction. The screen panels and sieves of a screening equipment can separate mixed material of different kinds into different classes of particle sizes through the combination of single-deck or multi-deck screens, so as to meet the requirements of a certain ore dressing process.

Some major factors affecting screening effects such as :

Screen panels and sieves made of different material affect significantly the screening efficiency of different kinds of material; the vibrating or jumping frequency on the screen sieve can increase the quantity of material screened, as well as separate the adhesiveness between materials so that more loose particles can pass the meshes;

(1)     shapes of holes in various sieves

(2)     staggered round holes

(3)     staggered hexagon holes

(4)     square holes

(5)     staggered square holes

(6)     rectangular holes staggered at bottom

(7)     rectangular holes staggered at sides

(8)     straightly-arranged rectangular holes

(9)     mostly applied and accurate, suitable for screen-separating of regularly-shaped particles  / square holes

(10)   When thicker screen wires are used, the precision rate drops due to high hole-opening rate and high throughput  /Rectangular holes

(11)  It has the highest hole-opening rate, but has a poor precision rate; if it is used by shifting it by 90 degrees, the precision rate will be improved; owing to the long holes and the vibration of screen wires, blockage does not tend to occur  /Long three-weft holes

(12)  Round  / Long service life, fixed precision, easy to be blocked, poor efficiency and low conveying capacity

(13)  Triangle  / Good precision, high efficiency, but low capacity in anti-blockage and conveying, holes enlarged after wears

(14)  equilateral triangle  /

(15)  Grizzly type  / The conveying capacity increases with the increasing of the height of rods, and the efficiency slightly drops when the rods become straight at both sides, and blockage gets worse

(16)  Guide-track type  / Normally it is co-operated with a grizzly in order to protect the rods and reduce the wear

(17)  Angled arrangement  / It can be used on any rod in any horizontal screen so as to increase the conveying capacity

(18)  Loose rod arrangement  / It can decrease blockage, but has a poor precision rate

Size of screen aperture: the larger the screen apertures are, the higher production rate the unit screen sieve area offers and the higher capacity of separation it offers; however, the sizes of screen apertures depend on the purposes and requirements intended. When it is intended to obtain material as fine as possible that passes the screen aperture among the upscreen material, smaller apertures shall be adopted; the other way round, when it is intended to obtain underscreen material with sizes larger than specified as much as possible, the aperture is not supposed to be oversized. The specified particle size shall be the limit of the width of screen aperture.

Rubber screen panels and sieves have the following advantages:

2.1 Depending on the shapes of material, the rubber screen panels and sieves can be easily designed with different aperture shapes;

2.2 Site installation and disassembly is made easier due to light weight of rubber screen panels and sieves;

2.3 The high damping of rubber screen panels and sieves can reduce noises;

2.4 The sound elasticity of rubber screen panels and sieves can increase the jumping frequency of material and raise screen separation efficiency;

2.5 Different framework materials can be added during the molding process of rubber screen panels and sieves so as to extend their service life;

Depending on our customers’ requirements, Naipu company can supply rubber screen panels and screen sieves with different aperture shapes, structures, sizes and formulations based on different types of screening equipment. Rubber screen panels and sieves produced by Naipu company. have a stronger advantage than those made of other materials in price-to-performance ratio for operations, and users are warmly welcomed to choose NSH Series rubber screen panels and sieves for screening equipment manufactured by Naipu company.
