Description

Vibrating screen discharging adjustable fineness modulus device Technical Field The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen discharging adjustable fineness modulus device. Background The vibrating screen is a high-efficiency screening device, and the vibrating screen is utilized to quickly separate and filter materials on the screen surface under the action of vibration. The vibrating screen mainly comprises a vibrating motor, a screen box, a screen, a damping spring and the like, and when the vibrating screen works, the vibrating motor drives the screen box to perform vibrating motion, so that materials roll and jump on the screen surface continuously, and the purpose of separating and screening is achieved. The vibrating screen is widely applied to various industrial production fields, such as mining industry, chemical industry, food and the like, so as to improve the production efficiency, reduce the production cost, improve the product quality and meet the environmental protection requirement. The fineness modulus is a comprehensive index for representing the granularity degree of aggregate (such as sand), is a dimensionless value obtained by calculation after standard screening test according to the particle content of different particle sizes, and is generally used for evaluating the granularity distribution of the sand and reflecting the proportion of fine particles, medium particles and coarse particles of the sand. The larger the fineness modulus value is, the coarser the aggregate particle size is, and the smaller the value is, the finer the aggregate particle size is.
