At present, China's production of circular vibrating screen mainly: YA circular vibrating screen, YKR circular vibrating screen, SZZ self-centering shaker, DD, ZD with single-axis shaker type mine, DDM, ZDM type of coal with a single-axis vibration Screen, YK type circular vibrating screen, DYS type large circular vibrating screen, SZ type inertial seat type circular vibrating screen, H, YH and YAH type heavy vibrating screen, etc., there are more than 100 specifications. Although it has a large number of models, it is essentially a type of self-centering vibrating screen (except for the SZ type).
SZZ self-centering shaker, with a single-axis shaker DD and ZD-type ore beneficiation is our plant since the 1960s of the 20th century's most widely used screening equipment, DDM and single-axis shaker with ZDM coal is our country coal preparation One of the most widely used screening equipments in the factory for many years, the YA type, YKR type, YK type and DYS type circular vibrating screen are the advanced screening equipments produced in China in the 1980s, and have been selected for many mines and coal mines. The STS type three-axis elliptical vibrating screen is a new type of equipment produced in recent years.
1.YA type circular vibrating screen YA type circular vibrating screen is a new type of equipment imported from the Anshan Mine. The RS company has the world's advanced level technology in the early 1980s and began production in the mid-1980s. The technical performance and quality level of the product. It has reached the level of similar foreign products. YA type circular vibrating screen adopts international advanced ring groove rivet, plate type screen box frame structure, eccentric shaft and eccentric block vibrator, high performance gear transmission system, low stress damping spring and super heavy duty large clearance bearing and thin Advanced technology and technology such as oil lubrication, with high strength of screen frame structure, reasonable mechanical structure, low temperature rise of large clearance bearing operation, small running noise, long service life, safe and reliable production and easy maintenance, suitable for beneficiation and selection For the classification of crop materials in coal, building materials, electric power and chemical industries, it can also be used for dehydration, de-mudging and de-intermediation, with good classification quality and high efficiency. In recent years, the screen has been widely promoted and applied in China, and has been well received by users.
YA type circular vibrating screen is divided into single layer and double layer, and has light and heavy weight, there are 40 kinds of specifications; screen mesh structure has woven mesh, punching sieve plate, and can also choose iron sill sieve plate; motor can be installed On the left or right side, the user installs and supplies according to the installation drawing when there is no special requirement.
Product model description such as 2YAH1836: 2 double layer (single layer is not injected), Y - circular motion, A - shaft eccentricity, H - heavy duty screen (light weight not), 18 - screen width (dm), 36 - Screen length (dm).
The performance and parameters of the YA type circular vibrating screen are listed in Table 1. The appearance and installation dimensions are shown in Figure 1 and Table 2. In addition to the Anshan Mine, the Shan Mine, Huai Mine and Xinhai Mining Machinery also produce YA series circular vibrating screens. Saddle weight produces similar YAg series circular vibrating screens and YAK series circular vibrating screens, where g is the improved design and K is the block eccentricity.

2.SZZ self-centering shaker The shaker is a traditional Chinese family, the most widely used as a screening device, available for mining, coal, metallurgy, building materials, chemical and other departments in the fine fraction of material grading Especially played an important role in the mineral processing industry. Therefore, there are many manufacturers of such vibrating screens, mainly including Anshan, Anzhong, Yankuang, Qunying, Nanzhong, Zhuneng, Huai Mine, Baotou, Dahua Heavy Machinery, Zheng Mine, Zhu Mine, and South Mine. Changfa Mining Machinery, Ningde Gravity Mineral Processing Equipment Manufacturing Plant (hereinafter referred to as Ningde City Gravity Selection Plant) and Xinhai Mining Machinery, etc., have about 20 specifications.
SZZ self-centering vibrating screen is divided into single layer and double layer. There are two types of installation methods: hanging type and seat type. Most of them are hanging type. Small size screen machine can also be equipped with mobile base frame. The screen structure has braided screen. Net and punching screen, motor can be installed on the left or right side, no special requirements to install according to the installation diagram. If the screen angle is changed as required, the seat type can be designed separately, and the hanging type can be realized by the user by adjusting the length of the wire rope of the hanging device. The basic bolts are generally provided by the user.
Model meaning example SZZ 2 1500×3000: S——vibrating screen, Z——center, Z——custom, 2——double layer (single layer not), 1500——screen width (mm), 3000— - Screen length (mm).
The products of Nanzhong are listed in Table 3. The products of Anshan Mine are listed in Table 4. The products of Nanfang and other manufacturers are listed in Table 5. The products of Huai Mine are listed in Table 6. The products of various mines are listed in Table 7. The shape and installation dimensions of the self-centering vibrating screens of various mines and saddle mines are shown in Figures 2-9. The shape and installation dimensions of several self-centering vibrating screens in Huai Mine are shown in Figures 10~12.

3. DD, ZD type single-axis vibrating screen for mining This series of circular vibrating screen has simple structure, convenient maintenance, reliable operation, high screening efficiency and good permeable. The whole series has 17 specifications for mine, coal and electric power. The division of medium-grained materials is classified by the departments of construction and chemical industry, and the classification of coke materials by rubber-tilted panels is particularly good.
DD, ZD type single-axis vibrating screen for mining is divided into single layer and double layer. The installation method includes hanging type and seat type. The screen structure has woven screen and rubber sieve board. Punching screen board can also be used. The motor can be installed. On the left or right side (no special requirements to install according to the installation diagram). When selecting, if it is required to change the screen inclination angle, it can be separately designed for the seat type screen, and the hanging type screen can be realized by the user by adjusting the length of the wire rope of the hanging device. The foundation bolts are all provided by the user.
Model meaning example 2D (Z) D1530J: 2 - double layer (single layer not numbered), D (Z) - hanging type (seat type), D - single axis, 15 - screen width (dm) , 30 - sieve length (dm), J - rubber sieve plate (non-rubber sieve plate is not injected).
At present, there are many manufacturers of DD and ZD mine single-axis vibrating screens, mainly including Anshan Mine, Shan Mine, South Mine, Saddle Heavy, Changfa Mining Machinery, Ningxin Plant, Shicheng Election, Huai Mine, Xinhai. Mining machine, Nanchang Mining and Metallurgical Machinery Factory (referred to as Nanye), Guangzhou Mine and so on.
