Abstract
The utility model provides a nickel ore uniformly mixing machine. The nickel ore uniformly mixing machine comprises a pedestal and a stander fixed on the pedestal, wherein a feeding hopper is arranged on the stander, a pair stirring rolls capable of oppositely rotating are arranged in the stander, a plurality of stirring teeth are uniformly formed in the peripheries of the stirring rolls axially, and the stirring teeth on the opposite stirring rolls are mutually staggered with one another. The nickel ore uniformly mixing machine has the beneficial effects that the structure is simple; by utilizing the stirring rolls which are capable of oppositely moving and are provided with stirring teeth, a nickel laterite ore raw material, calcined lime and blast-furnace return ores are adequately mixed, and the processed nickel laterite ores are ground into small particles; in a processing process of the nickel ore uniformly mixing machine, the utilization rate of a water-absorbing material is high, the dust is little, and the secondary pollution is avoided.
Description
Technical field
The utility model relates to a kind of nickel minerals mixing machine.
Background technology
Along with steel industry enters meagre profit or loss period, reduce costs, improve enterprise competitiveness and become the direction of each iron and steel enterprise's research, existing iron and steel mostly uses 7%～12% lateritic nickel ore to carry out sintering and uses for blast furnace.
Because lateritic nickel ore water content is large, about more than 30% nickel minerals is comparatively sticky glutinous, thereby first a lot of factories employing quick lime and BF return fines water suction, and lateritic nickel ore moisture content drops to 10%～15%, places and sieves two days later, thereby reach sintering plant user demand.
In above-mentioned technique, the steel plant of existing use lateritic nickel ore all adopt hook machine puddle or with baking mode carry out, the former on-the-spot dust is very large, quick lime loss is serious, and cannot realize and mixing efficiently, adopt the mode output little (40～50t/h) of baking, and due to the baking of 12000m/h blast furnace gas, cause secondary pollution.
Summary of the invention
The utility model improves the problems referred to above, and the existing lateritic nickel ore that the technical problems to be solved in the utility model is anhydrates and adopts in hybrid technique hook machine to puddle or by the method for baking, dust is large, and raw material loss causes greatly and easily secondary pollution.
Specific embodiments of the present utility model is: a kind of nickel minerals mixing machine, described nickel minerals mixing machine comprises base and is fixed on the frame on base, described frame is provided with feed hopper, in described frame, be provided with a pair of agitating roller that can rotate in opposite directions, described agitating roller peripheral part is evenly equipped with some stirrer gears vertically, and the stirrer gear on described relative agitating roller staggers mutually.
Further, described frame one side is provided with overload protection device, and described overload protection device comprises the spring base that is fixed on frame, and described spring base outside is provided with spring bearer plate, between described spring bearer plate and spring base, is provided with spring.
A kind of nickel minerals mixing machine according to claim 2; agitating roller rear side cover near overload protection device in described frame has a cover body; described cover body outside is provided with an adjustment screw rod; cover body is fixed on through nut in described adjustment screw rod one end; the other end stretches out spring bearer plate outside through spring base, and described spring base outside is also provided with and is placed on the locking nut of adjusting screw rod outside.
Further, described agitating roller is driven and is rotated by the drive unit that is arranged at nickel minerals mixing machine side, and described drive unit comprises motor and decelerator, and described decelerator is driven through a shaft coupling and is connected with the rotating shaft at agitating roller middle part by motor.
Further, between the interlaced stirrer gear of described two agitating rollers, gap is less than 2 ㎝.
Further, described agitating roller rear side is provided with screw-down type grease cup.
Compared with prior art, the utlity model has following beneficial effect: the utility model is simple in structure, agitating roller by move toward one another with stirrer gear, fully lateritic nickel ore raw material is mixed with quick lime and BF return fines, and lateritic nickel ore after treatment is rubbed and forms less particle requirement, utilize in this device processing procedure, to absorb water that raw material availability is high, dust is few and can not cause secondary pollution.
