ZDS series elliptical equal thickness screen
Elliptical equal thickness screen is used for ore classification of sinter, sinter pellet and mining industry in metallurgical industry, and classification and screening operation in coal industry. Compared with other types of sieving machines of the same specifications, the processing capacity is larger and the screening efficiency is higher. It is the first choice of large-scale vibrating screen in large-scale sintering plant, pelletizing plant, concentrator, coal preparation plant, and is an ideal substitute for imported large-scale vibrating screen.
Working principle and structural features:
Working principle: the screen surface of ZDS series screen is composed of three sections with different inclination angles, which makes the thickness of each section of material layer on the screen surface approximately equal; adopting the principle of three-axis drive and forced synchronous excitation, the motion state is stable. The motion track of the screen box is ellipse, and the elliptical equal thickness screen is conducive to the forward transportation, stratification and sieving of materials on the screen surface, so it has larger processing capacity and higher screening efficiency than ordinary linear screen and circular motion screen. However, when the same treatment capacity and screening efficiency are the same, elliptical equal thickness screen has a smaller screening area, which can save investment.
Structural features: elliptical equal thickness screen is composed of screen box, vibration exciter, vibration isolation system and transmission device. According to the properties of screened materials, the material of sieve plate can be polyurethane or wear-resistant alloy. The eccentric block of vibration exciter is driven to rotate by motor through synchronous transmission device. The ellipticity and direction angle of the motion track of the screen box are adjustable.
