Take this shale shaker upgrade strategy to meet more material screening!

[technical article of China Pharmaceutical network] vibrating screen is suitable for screening and filtration of powder, granule and liquid, widely used in fields such as chemical fertilizer and pharmaceutical powder, and also used for screening and filtration in the process of sewage and wastewater treatment in environmental protection industry It is reported that the vibrating screen on the market can be divided into special vibrating screen and multi-functional vibrating screen As the name implies, the special vibrating screen is a kind of screening equipment for a specific material, while the multi-functional vibrating screen can achieve a machine to screen materials of different shapes, sizes and characteristics for different purposes For users, the screening effect, function and cost performance of the vibrating screen equipment are the factors they care about when they choose the model Compared with the multi-functional vibrating screen, the special vibrating screen is more in line with the needs of small and medium-sized pharmaceutical enterprises in terms of price and space Some customers ask if the special vibrating screen has the upgrading strategy to meet the screening of more materials? The manufacturer of the shale shaker said that the key to upgrade from the special type to the multi-functional type is to adjust the screen, amplitude and exciting force of the shale shaker in a diversified way so as to realize the variability of these three parameters Method 1: replace the screen The particle size of materials varies greatly according to the different shapes and types Therefore, in order to realize the screening of various materials by special vibrating screen, it is necessary to make the mesh number of the screen varied According to the manufacturer, the simpler way is to purchase multiple screens with different mesh numbers from the vibrating screen manufacturer or the nearest manufacturer, and replace the screens manually according to the demand, so as to realize the screening of various materials It is worth noting that the screen is a part of the vibrating screen equipment that directly contacts with the material, and it is an important guarantee to determine the screening accuracy and output value of the material However, many users often find that the screen is broken Industry insiders suggest that users should pay attention to: the oscillating force should not be too large, it should be within the range of equipment, and the feeding amount should not be too large to prevent the screen from breaking In addition, the quality of the screen is determined by the selection of materials, the thickness of silk warp and the placement of warp and weft during weaving, so good suppliers should be selected when selecting relevant accessories Method 2: change the vibration amplitude of the shale shaker according to the material characteristics It is understood that in order to achieve better screening effect for materials with different properties, the vibration amplitude of the shale shaker needs to be adjusted accordingly, because different materials have different shapes due to the molecular structure, and the requirements for the vibration amplitude are also different For example, the materials with heavy specific gravity and good fluidity are suitable for screening with low amplitude, while the materials with poor fluidity generally need to use high amplitude to achieve better screening effect Method 3: adjust the vibrating screen force according to the output requirements and the difficulty of material screening It is understood that the adjustment of the vibrating screen force is mainly achieved by changing the angle of the upper and lower hammers of the vibrating motor According to the introduction, the reason why the vibrating screen force should be changed is that the viscosity, water content and specific gravity of the materials are closely connected with the screening rate, and the output of the two different materials on the same equipment is also quite different Therefore, it is necessary to increase the vibrating screen force to ensure a certain production efficiency when screening the materials that are difficult to be screened, and reduce the vibrating screen force to reduce unnecessary energy waste when screening the materials with high screening rate The manufacturer also said that the size of the vibrating screen force is not only related to the type of materials, but also closely related to and proportional to the mesh number of the screen, that is, the larger the mesh number requirements, the more suitable for using a larger vibrating screen force.
