Proper screen tension is crucial for effective screening and longer screen life. Proper screen tension helps spread material across the full width of the screen. Uniform tension must be also maintained on the screen surface to prevent whipping and to maintain contact between the screen surface and the capping rubber (also called channel rubber, bucker-up rubber, etc.) on the longitudinal support (...

Banana (Multi-slope) screens have become widely used in high-tonnage sizing applications where both efficiency and capacity are important. Banana screens typically have a variable slope of around 24°-45° at the feed end of the screen, reducing to around 0°-8° at the discharge end of the screen. Banana screens are usually designed with a linear motion/stroke vibrator. Stage 1: High velocity The fee...

Installation The supporting steel structures on which the screen and drive motor are mounted must be sufficiently strong and braced to accept without deflection the dynamic loads caused by the vibration of the screen. Adequate clearances must be allowed between the screen and the fixed structure, chutes etc., to allow enough space because the movement of the screen is large in the so-called resona...

The main obstacles to efficient screening are plugging/pegging, blinding and carryover. Each can be minimized with a variety of solutions. Plugging/pegging happens when near-size particles become lodged/wedged, blocking the openings. Generally, if loose particles/rocks (“Carrots” Shape) get stuck in the media holes it is called plugging whereas if particles get jammed in the openings, it is called...

Size control is the process of separating bulk material into two or more products on basis of their size. In mineral processing practices, two methods dominating size control processes are: screening and classification. As shown in the following figure, while screening uses a geometrical pattern for size control, classification uses behavior of particle’s (finer than 1 mm) motion in air or liquids...

Vibratory feeders have been used in the manufacturing industry for several decades to efficiently move fine and coarse materials which tend to pack, cake, smear, break apart, or fluidize. Because they can control material flow, vibratory feeders handle bulk materials across all industries, including pharmaceuticals, automotive, electronic, food, and packaging. These feeders also advance materials ...

When the vibrating screen is started, sometimes it cannot be started properly. The following is to give you an analysis of the reason and solutions: 1. The voltage required by the vibrating screen is 380v three-phase power, please make sure that you use a three-phase power supply 2. Motor is damaged, need to replace the motor 3. Electrical components in the control line are damaged and need to be ...

1. Introduction Large vibrating screen is widely used for screening, grading and dewatering in mining, metallurgy and chemical industries [1-3]. In the working process the beam of the vibrating screen is impacted by the particles and corroded by slime water, which result in fatigue fracture of the beam and suspended production [4]. If the fatigue crack of the beam is diagnosed and the fatigue resi...
