Description
Technical field
The utility model belongs to the slag comprehensive utilization technical field.
Background technology
Utilize slag to produce the history of slag silicate cement at the existing many decades of China.Because original technology of slag tailings processing steel slag cement base-material of utilizing is limit, slag steel content is higher in the steel slag cement base-material of processing, generally more than 5%.Because the existence of a large amount of slag steel in the steel slag cement base-material, and that the slag steel is difficult to is levigate, and can form infringement to grinding element, cause in the production process abrasion higher, mill efficiency is lower, the cement fineness of producing is not high yet, has greatly influenced the quality of steel slag cement, has influenced the usage quantity of steel slag cement yet.
The utility model content
The utility model is higher at slag steel content in the existing steel slag cement base-material, the ropy problem of steel slag cement, and the utility model provides a kind of preparation facilities of steel slag cement base-material.This device has reduced the content of slag steel in the steel slag cement base-material, has improved the quality of steel slag cement.
To achieve these goals, the utility model proposes following technical scheme:
A kind of preparation facilities of steel slag cement base-material, it comprises magnetic separator No. one, a described magnetic separator back is provided with sieve apparatus No. one, the back, sieve top of a described sieve apparatus is provided with crusher No. one, the branch back, lower part of screen of a described sieve apparatus is provided with magnetic separator No. two, and the back of a described crusher is provided with magnetic separator No. two.
Between a magnetic separator noted earlier and the sieve apparatus, between a described sieve apparatus and the crusher, between a described sieve apparatus and No. two magnetic separators, all be connected between a described crusher and No. two magnetic separators by belt.
Scheme noted earlier is a screening slag steel process, can be implemented in the slag tailings screening steel of slagging tap by described process, with the tailings that screened the slag steel as the cement base-material can so that in the cement iron-holder greatly reduce.
Can also proceed screening after said process again: be provided with No. two sieve apparatus in the back of described No. two magnetic separators, the back, sieve top of described No. two sieve apparatus is provided with crusher No. two, and the back of described No. two crushers is provided with magnetic separator No. three.
Between described No. two magnetic separators and No. two sieve apparatus, between described No. two sieve apparatus and No. two crushers, between described No. two sieve apparatus and No. three magnetic separators, all be connected between described No. two crushers and No. three magnetic separators by belt.
When above-mentioned second took turns screening process, the sieve diameter of a sieve apparatus in can first round screening process was set to 20mm, and the sieve diameter of No. two sieve apparatus is 8mm, thereby realizes fragmentation and magnetic separation better.
A foregoing magnetic separator, No. two magnetic separators and No. three magnetic separators can all be set to magneticstrength between 0.3-0.4T.
The continuous grading that the slag tailings is made up of the material of different-grain diameter, before each fragmentation, sieve, will need broken segment and not need broken segment to separate, only the bulk slag is carried out fragmentation, can improve crushing efficiency, multi-stage screening can improve screening efficiency simultaneously.Select suitable magneticstrength to separate the slag steel, can guarantee effectively to sub-elect the slag steel in the slag tailings, make the slag steel content in the product reach the quality product requirement, guarantee that again selected slag steel has higher quality simultaneously, therefore the effective recycling of slag steel can be beneficial to and apply.
