Vibrating screen for gypsum processing

What is a vibrating screen for gypsum processing?

Vibrating screen for gypsum processing is a screening equipment used for particle size grading, impurity removal or dehydration of gypsum ore or gypsum powder. It is widely used in the pre-crushing screening, pre-grinding grading and finished product screening of raw materials such as building gypsum, desulfurized gypsum, and phosphogypsum. Because gypsum materials have the characteristics of large particle size span, easy moisture absorption and agglomeration, and high dust, the vibrating screen used is usually required to have anti-blocking nets, good sealing and high screening efficiency.

According to different process requirements, single-layer or multi-layer screening structures can be selected. For example, circular vibrating screens are often used to remove large impurities in the coarse screening stage, linear vibrating screens are often used for particle size control in the medium screening and grading stages, and rotary vibrating screens are often used in the fine screening stage to finely grade gypsum powder.

What types of vibrating screens are there for gypsum processing?

In the field of gypsum processing, vibrating screen is an indispensable key equipment. It mainly uses the principle of vibration to efficiently screen gypsum particles and powders, achieve accurate classification of different particle sizes, and effectively separate impurities. The vibrating screens used in gypsum processing mainly include rotary vibrating screens (circular vibrating screens), straight screen, linear vibrating screens, ultrasonic vibrating screens, etc., which ensure that the gypsum raw materials required for subsequent production links meet strict fineness requirements, thereby ensuring the quality and performance of the final gypsum products. It is an important guarantee for improving efficiency and product quality in modern gypsum production lines.

Rotary vibrating screen uses a vertical vibration motor to make the screen surface produce horizontal, vertical and inclined three-dimensional vibration, thereby achieving efficient layered screening. It is particularly suitable for fine screening of small batches of gypsum powder, such as the processing of ultrafine powder of 325 mesh and above. The rotary vibrating screen has high screening accuracy (up to 95% or more) and can be configured with 1 to 5 layers of screens. It is widely used in the deep processing of gypsum powder, such as fine screening, impurity removal or particle size classification of gypsum retarders and gypsum-based coatings.

Straight screen uses a vibration motor to quickly discharge the material on the screen along a straight line trajectory, achieving efficient screening under large feed rates. It is particularly suitable for rapid screening and impurity removal of gypsum powder, such as impurity removal of gypsum powder on a gypsum powder production line. It is widely used in the initial screening and rapid impurity removal of gypsum powder, such as coarse screening and impurity removal of gypsum powder in gypsum building material production.

Linear vibrating screen allows the material to move linearly on the adjustable screen surface, achieving a long-term retention of the material and a stable classification effect. Therefore, it has the characteristics of large processing capacity and high screening efficiency. It is suitable for coarse or medium screening of gypsum particles, such as separation of coarse particles (such as coarse particles larger than 10 mm) after desulfurized gypsum and natural gypsum crushing, and particle size classification of gypsum mortar raw materials.

Ultrasonic vibrating screen generates high-frequency micro-vibration of the screen by superimposing the ultrasonic screening system, thereby effectively solving the problem of fine powder agglomeration or screen hole blockage. It is suitable for high-purity, high-fineness (such as 800 mesh or above) viscous and easy-to-agglomerate materials such as gypsum powder. It is widely used in ultra-fine screening of high-end gypsum products such as medical gypsum and precision casting gypsum, as well as processing gypsum powder with high water content.

What is the function of vibrating screen for gypsum processing

During the processing of gypsum, whether it is the mining, crushing, grinding of natural gypsum, or the processing of industrial by-product gypsum (such as flue gas desulfurization gypsum), there are the following requirements:

Grading: Separate gypsum raw materials or finished products according to different particle size requirements to meet the needs of different products (for example, coarse aggregate gypsum for building materials, and ultrafine gypsum powder for fine molds or additives).

Impurity removal: Remove impurities and non-gypsum substances with larger particles mixed in the gypsum raw materials to improve product purity.

Dehydration: For wet-process or water-containing gypsum materials, the vibrating screen can perform preliminary dehydration treatment to reduce the energy consumption of subsequent drying.

What are the advantages of vibrating screen for gypsum processing

The advantages of vibrating screens in gypsum processing are clear and practical. First, it can accurately screen gypsum powder of different mesh sizes to meet your particle size requirements for different products such as putty powder and gypsum board, avoiding problems such as wall cracking and insufficient board strength caused by uneven particles; second, the good screening effect reduces production time, allowing you to get customized gypsum materials faster, especially when the construction schedule is tight; third, the equipment has good sealing and dust removal design to reduce dust pollution and ensure a clean working environment in your workshop; fourth, the wear-resistant material and stable structure extend the service life and reduce maintenance and replacement costs. In long-term cooperation, we can continue to provide you with reliable gypsum raw material screening guarantees.

Model parameters of vibrating screen for gypsum processing

In the process of gypsum processing, vibrating screen is often used for screening of raw gypsum, grading of gypsum powder after crushing, and particle size control of building gypsum or desulfurized gypsum particles.

What is the purpose of vibrating screen in gypsum processing

The vibrating screen for gypsum processing plays a key role in all aspects of gypsum production. After the gypsum ore is mined, the crushed material is coarsely screened through a circular vibrating screen or a linear vibrating screen to separate large particles larger than 50 mm and return them to the crushing process to ensure that the particle size of the material entering the grinding process is qualified; in the grinding stage, the rotary vibrating screen and the ultrasonic vibrating screen can classify the calcined gypsum powder according to the fineness, for example, α gypsum and β gypsum are screened into different specifications such as 325 mesh and 800 mesh to ensure that the fineness of the finished product meets the standard; in the treatment of slurries such as desulfurized gypsum and phosphogypsum, the dehydrating vibrating screen and the wet linear screen can effectively separate the solid and liquid, reduce the water content of the gypsum slurry to 10%-15%, and recover the solid gypsum; in addition, in the batching of gypsum products, the vibrating screen can also screen the mixture of gypsum powder and additives such as retarders and fibers to ensure that the material uniformity and impurity content meet the requirements, and help produce high-quality gypsum boards, gypsum mortars, medical gypsum and other products.

How to choose a vibrating screen for gypsum processing

Vibrating screen for gypsum processing is an important screening and grading equipment on the gypsum production line. Its role runs through multiple links from raw ore pretreatment to finished gypsum powder quality control, and optimizes the entire production process. By reasonably selecting a vibrating screen, the degree of refinement of gypsum processing can be improved to ensure the quality stability of the final product (such as gypsum board, gypsum mortar, medical gypsum, etc.).
