Embodiment

[0028] Example: During the rainy season, in order to prevent collapse, the height of the stockpile will be reduced from the existing 10m to 8m, the total amount of stockpiles will be reduced to 85,000 tons, the average consumption of sintering machine burnt materials is 20,000t / d, and the batching amount of the raw material field is 19,000t~ About 24,000t (1500t / h in rainy days, 1800t / h in sunny days), each stockpile is used for about 5 days, and within 5 days, the maximum ingredient surplus is 2.0 tons, which is only enough for sintering for 1 day. Through improvement, the secondary material The stockpiling capacity of the yard increased from 90,000 tons to 125,000 tons, and the stockpiles of ingredients were reduced from 6 stockpiles / month to 5 stockpiles / month, reducing the end-end tailings by about 4,000 tons / month, and the quality of sinter was more stable and more effective. Assure.

Abstract

The invention relates to the technical field of schreyerite, and discloses an improving method for comprehensive capacities of a schreyerite stock yard secondary material yard. The improving method comprises the following steps that (1) a conventional site is planned and measured through professional staff, normal mounting and reasonability of equipment are guaranteed, and equipment chaos and potential safety hazards are avoided; (2) conventional uniformly mixed material strips are extended through construction instruments according to a planning scheme till the material strips are extended toproper length; and (3) a conventional stacker is studied and observed, a depression angle lifting problem of the stacker is simulated and studied, and the stacker lifts secondary material stock pilesto the maximum extent under the precondition that safety operation of the stacker is guaranteed. According to the improving method for comprehensive capacities of the schreyerite stock yard secondarymaterial yard, normal amount of sintering feed in rainy season can be guaranteed, the situation that an operator does not have time to maintain the stacker and other equipment as the feeding pace isquick is prevented, and quality of sintered ore is more stable.

Description

technical field [0001] The invention relates to the technical field of vanadium-titanium ore, in particular to a method for improving the comprehensive capacity of a secondary stockyard of a vanadium-titanium ore raw material field. Background technique [0002] Vanadium is known as "the monosodium glutamate of modern industry". It is widely used in the fields of steel, chemical industry and aerospace. Rare metals have a wide range of uses. It is known that vanadium is mainly used in alloys to improve the properties of steel. [0003] The maximum storage capacity of the secondary stockyard of the raw material yard is limited under the current two-pile and two-take mode, and the secondary stockyard of the raw material yard is an open-air stockyard, and the height of the stockpile is greatly affected by the rainy season. During the rainy season, in order to prevent collapse, the height of the stockpile will decrease, and the total amount of piled material will decrease with t...
