Embodiment 1

[0017] Embodiment 1: The trapezoidal protrusion is located on the discharge side of the strip plate body, the small end of the trapezoidal protrusion faces the discharge side, and between two adjacent strip plates, the strip shape near the feed side The trapezoidal protrusion of the plate is welded above the body of the strip plate near the discharge side. The structure described in this embodiment is easy to manufacture and has excellent screening effect.

Embodiment 2

[0018] Embodiment 2: The trapezoidal protruding part is located on the feed side of the strip plate body, the large end of the trapezoidal protruding part faces the feed side, and between two adjacent strip plates, the strip plate near the discharge side The trapezoidal bulge is welded under the body of the bar near the feed side. The structure described in this embodiment has a better screening effect for some specific ores.

[0019] The full trapezoidal through-hole sieve plate can be used independently, or the alternate layout of trapezoidal through-hole sieve plates and round-hole sieve plates can be used to improve the screening efficiency. After entering the vibrating screen during the process, the blocking problem is greatly improved, the screening effect is better, the fine powder rate is significantly reduced, the residence time (or cycle time) of the material in the system is significantly shortened, the service life of the sieve plate is significantly extended, and ...

Abstract

The invention discloses a vibrating screen plate used for ore crushing and separation. A plurality of through holes is formed in the screen plate, some or all of the through holes are trapezoidal through holes, the small head ends of the trapezoidal through holes face the feeding side, and the large head end face the discharging side. According to the vibrating screen plate, through the above through-hole structure, ore is not prone to being clamped in the through holes during screening, material blocking cannot occur, the hole wear is greatly reduced, and the screening efficiency is significantly improved; the screen plate is composed of a plurality of strip plates connected sequentially in the feeding direction, the length direction of each strip plate is perpendicular to the feeding direction, one side of each strip plate body is provided with a plurality of trapezoidal protrusions, and one of every two adjacent strip plates is connected with the trapezoidal protrusion of the otherone strip plate; and rolling of the ore is facilitated through the stepped screen plate structure, and the occurrence of material blocking can be further avoided.

Description

technical field [0001] The invention relates to ore screening equipment, in particular to a vibrating sieve plate used for crushing and separating ore. Background technique [0002] At present, Panzhihua Iron and Steel Xichang Steel Vanadium Vanadium Products Branch is the only one that uses large-scale tilting furnace electric aluminothermic method to smelt ferrovanadium at home and abroad. At present, the round-hole vibrating sieve plate is used to sieve ferrovanadium in the crushing process. Since the crushing of ferrovanadium adopts the process of "two-stage jaw crushing + vibrating screen screening", and the screening uses a round-hole sieve plate, during the crushing and screening process, the material is blocked seriously, the screening effect is poor, and the round hole is easy to wear and become deformed. Large, resulting in long crushing time of ferrovanadium, high fine powder rate, gradually larger product particle size, lower production efficiency, higher product...
