In the sand production line, in addition to equipment such as crushers and sand making machines, other auxiliary equipment is also needed to improve the production efficiency of machine-made sand, such as vibrating feeders, vibrating screens, belt conveyors, etc. Among them, vibrating screen for mining is an essential auxiliary equipment. Advantage 1. With advanced structural design and prod...

Vibrating screens consist mainly of: screen body (vibrating basket / live frame), vibrator assembly (vibrating unit), screening media, supporting frame and drive unit. Above figure shows components of a typical vibrating screen. Screen Body The side plates of screen body are reinforced with plates and angles or channels. The side plates are connected to each other by the screen deck (bucker-up-fra...

Oil Lubrication Manufacturers will design grease lubrication systems because it simplifies sealing, making it the most economical choice. In addition, the grease acts as an additional barrier against contamination. However, grease is not suitable for all applications due to its inability to operate at higher speeds. Oil Lubrication allows the bearing to operate at higher speeds, dissipates heat qu...

Basic Terms Stratification This phenomenon occurs as vibration is passed through a bed of material. The vibration of the machine sifts the material bed so that finer material passes through the coarser material. This enables particles smaller than the mesh of the screen to pass through it. Bed Depth It is the depth of the material on any given screen deck. The depth of the material on the screen a...

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 (...

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...

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 ...

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...

The technical-economic indicator of screening process are screening efficiency and productivity. The former is quality index, the latter is quantity index. There is a relationship between those two indexes, We need to make sure what factors will affect the screening process before purchasing a vibrating screen. Those factors can be classified into three categories. 1. Physical properties of bulk m...
