As a rule, dry screening at less than around 5 mm aperture size must be performed on perfectly material, unless special measures are taken to prevent blinding. These measures may include using heated decks to break the surface tension of water between the screen wire and particles, ball-decks (a wire cage containing balls directly below the screening surface) to impart additional vibration to the underside of the screen cloth, or the use of nonblinding screen.
Aug 09, 2021 For a circular vibrating screen, the moving speed of the material along the screen surface is related to the inclination angle of the screen surface. The relationship between the thickness δ of the material layer and the sieve size a is shown on the right δ≤(3~4)a the relationship between the thickness and the average particle size d0 of.
Operating viscosity at 75 C (165 F) is around 40 mm 2 s, based on diagram 3. κ = ν ν 1 = 40 10 = 4 is confirmed Relubrication interval and quantity. Experience suggests relubricating the bearings in the vibrating screen every 75 h with 30 g of grease.
Pre-sized raw coal (-50 x 0 mm) is mixed with water and passed over a deslime screen to remove the fine material i.e. below 0.5 mm or 1.0 mm in size. The undersize material passes to the fines treatment circuit(s) and the oversize ‘deslimed coal’ is mixed with the correct medium and pumped to a dense medium cyclone by the cyclone feed sump.
As per different size sieving demand, there will be 1-4 screen section from small size to big size, the oversize than the 4 th size will be discharged from outlet. It can be equipped with the comb type cleaning device which can make the continuously cleaning for screen mesh during the sieving process so as to make the screen mesh keep smoothly.
Basic formula for calculating screen area (per deck) • U Required screening area (Sq.ft.) • A Nominal capacity for separation • B Oversize (.33 – 1.21) • C Halfsize (.40 – 2.40) • D Deck location (.80 – 1.0) Screening Area = U (A x B x C x D x E x F x G x H x J) • E Wet screening (1.0 – 1.25) •.
Jun 20, 2016 The problem arises when the hole size is large (50 mm or ). In practice, the stroke used in a horizontal screen is 7 – 20 mm. A small stroke can be used when screening with a small hole size. Because of mixing and separation, a large stroke is recommended. Stroke is defined by the swinging mass and the flywheel moment of the vibration unit.
