sieve is sieving important working parts to complete the screening process, each shaker should choose a job in line with its requirements sieve. have an impact various characteristics, different structures sieve, various parameters of materials and shaker
product are vibrating sieve screening capacity Jaw Crusher In Turkey (http://www.lynbrookaquatics.com/)
, efficiency, run rough and life, different materials, different in different places should be used sieve to achieve the best results screening.
sieve should have sufficient strength, a higher opening rate and easy clogging properties. When the shaker vibration sieve through different shapes and sizes of materials, material size, the role of vibration force will separate materials of different particle size, reach grade purposes.
comb sieve:
comb sieve having a non-blocking, high screening efficiency significantly, suitable for higher coal, metallurgy, chemical industry, sintering, clinker, coke and various raw block ore hardness, greater weight of dry material, the sieve according to choose different materials, can achieve different life.
according to different materials can be divided into: the new wear-resistant alloy plate, high wear-resistant alloy plate, stainless steel casting sieve, sieve spraying, welding plate, wear-resistant steel sieve, sieve ordinary.
large comb sieve:
The sieve is suitable for coke, ore screening, its advantages are not blocking materials, resonance factor, high screening efficiency. The sieve according to screening different materials, length of life, use of different materials cover (material: wear resistance, high abrasion resistance, wear-resistant alloy, spraying, welding, etc.) for users to choose. Grade material particle size: 25-80mm
welding seam weld seam
sieve sieve sieve bars and is welded frame made of.
main screen bar made of stainless steel, with most of 1Cr18NiqTi and 1Cr18Niq. There are some cases, it may be less expensive and ordinary 1Cr17,1Cr13 45 # steel.
sieve angle: 20 ° -30 ° moderate grade material particle size:. 6-80mm
addition to casting strip every plate, its materials are stainless steel, ordinary steel, etc.
metal wire cloth sieve:
woven wire sieve bend buckle is embossed with wires woven, mesh size of a square or rectangular shape. Its advantages are: light weight, opening rate; and in the screening process, because the wire has a certain flexibility, but for the high-frequency vibration, so stick to the wire off fine-grained materials, thereby improving the screening efficiency. Suitable for grading the job fine grade material. But its drawback is that life is short.
woven wire mesh coarse pores and pore surface points two kinds. Rough hole woven mesh manufacturing materials, low-carbon structure steel, spring steel and stainless steel wire. Mesh size is generally: 4-125mm, wire diameter is 1.6-12.5mm. Pore braid generally consists of mild steel, brass, tin, tin, copper, and stainless steel sheet and other materials, a dedicated knitting machine woven. Its opening ratio: 36% -80%, mesh size: 0.03-16mm. Suitable sieve angle: 18 ° -30 °.
hot casting sieve sieve:
the sieve having a heat resistance, wear resistance, corrosion resistance, high impact strength plate, is mainly used for screening operations sintering, coke, ore and other raw materials.
cold casting sieve sieve:
the sieve with wear, corrosion resistance, high impact strength plate, is mainly used for screening operations sintering, coke and other raw materials. Production types are: a variety of shapes of cast stainless steel sieve, sieve high strength wear-resistant casting, ordinary steel plate, high-chromium steel sieve, sieve and other ductile iron. Its mesh shape rectangular hole Nigeria Best Stone Crusher Plant Supplier (http://www.ngacrusher.com/), square hole, diamond hole, comb hole, the word hole and the tapered hole and so on.
plate-shaped sieve:
plate-shaped sieve is a method for drilling or punching of perforated steel plate, the thickness is 5-8mm, the thickness of not more than 12mm. Advantages of the plate-shaped sieve is: relatively strong, long life; the drawback is low porosity; generally 40% -60%. Mesh size is generally 6-80mm, common pore diameter 10-50mm. Screen surface of the plate-like material, has good wear resistance, commonly 16Mn, 16MnCu, 16MnCr other steel, sometimes with Q235-A steel plate. Shape more circular holes, in some cases, also the use of square holes, rectangular holes, hexagonal holes, a mesh may be arranged in parallel to be staggered.
polyurethane sieve:
polyurethane elastic sieve sieve is a polymer, which has excellent abrasion resistance, oil resistance, hydrolysis resistance, fungus, anti-aging properties. The sieve not only can greatly reduce the weight of the equipment, reduce equipment costs, extend life, and reduced noise, widely used in mining, metallurgy, coal, coke, coal, petroleum, chemical and other industries washing and grading operations shaker. shape
polyurethane sieve holes are: comb, square hole, a long hole, round hole and seam type and so on. grading granularity
materials: 0.1-80mm.
