The heavy vibrating screen esigned and manufactured by Henan Hongxing Mining Machinery is put into use in the open pit coal preparation plant in 1983 to replace the spiral screen for sculping gangue and grading the large and medium blocks, which has conducted innovations and practices for the heavy vibrating screen products. A lot of large equipments of Henan Hongxing Mining Machinery are imported from the foreign countries. The super heavy screening equipment is needed to match for the equipment imported. In 1992, Henan Hongxing Mining Machinery successfully developed the YAC-2460 super heavy vibrating screen, whose maximum feeding size can be up to 400mm with a capacity of 1000t/h. Good results have received after it has been put into use.

Vibration screen is usually used to classify material in different size. Rounding Vibrating Screen has been widely used in chemical industries, transportation, construction, energy and mine. It is a multi-layer and high efficient vibrating screen. The screen line of material is long and the screening specification is various. Every screen specification is clear. It adopts the tubbish vibrator and eccentric adjustment, with the feature stable structure, strong exciting force, high efficiency, easy to maintain and durability, handy maintenance and safety.

Vibrating Screen is one of the auxiliary equipments in stone production line. Although Vibrating Screen doesn"t play an important role in the whole production line like Jaw Crusher or Sand Maker, it"s necessary. It can not only screen different final sizes but also screen waste garbage.

The rocks that have been crushed are mixed rockes with different sizes. Before using them or further process, we often need to grade these rock materials into different levels with different granularity. Screening refers to the grading process of separating the mixed materials with different sizes according to their different granularity by means of the multi-hole working face. The multi-hole working face is called screening face and the machine with a screening face that is used for grading materials is called a screening machine. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like sand making machine, Henan Hongxing is always doing the best in products and service.shaking concentrator:http://www.china-mills.com/p21.html

The screening process can be divided into three stages, the first screening of the crude ores, the second screening before the burning, the fine screening with the strong magnetic and weak magnetic beneficiation and the residue removing screening in the process of the strong magnet beneficiation.

The detailed screening process is that the crude ores are screened for the first time and the new can get two kinds of products which are powder ore and lump ore. The lump ore will be screened for the second time and then goes into the shaft furnace for roasting, and the powder ore will directly goes into the strong magnet beneficiation process for screening. Hydrocyclone equipment and spiral grading machine belong to gravity grading equipment which means that these machines grade materials with the sedimentation theory and the grading efficiency is very low. Generally speaking, it is 30% to 40%.

Rounding Vibrating Screen is a multi-layer and high efficient vibrating screen( three layers or four layers), it is often used after the use ofJaw Crusher orImpact Crusher. Henan Hxjq adopted eccentric block to produce strong exciting force and the screen are connected with high strength screw bolts. So they have the features of simple structure and easy maintenance.

The domestic vibrating screens can be divided into circular vibrating screen, linear vibrating screen, oval vibrating screen, high frequency vibrating screen, high frequency vibrating fine screen, sieve bend, banana vibrating screen, probability screen, cold griddle, hot griddle and dewatering screen, which are more than 50 series and nearly 1000 kinds of specifications. The products have been widely used in many industries, such as metallurgy, mining, coal, electricity and building materials, which basically meet the needs of domestic economic construction. According to the industry survey in 2002, the screening machinery manufacturing enterprises have been more than 300.
