Description
Technical Field
The utility model relates to a slag processing technology field, concretely relates to be suitable for production line of steel slag processing's horomill that crouches.
Background
The horizontal roller mill has the working pressure between the vertical mill and the roller press, adopts medium pressure, has better energy-saving effect, has low energy consumption and metal abrasion, and is suitable for milling steel slag. The horizontal roller mill system is lack of iron removal and iron discharge functions, when the milled materials contain iron, metal particles are difficult to mill and cannot be collected through powder selection and dust collection, so that iron enrichment is formed in the mill system, MFe can be enriched to about 10%, working of the mill is affected, equipment abrasion is caused, and energy consumption is increased.
SUMMERY OF THE UTILITY MODEL
The above-mentioned not enough to prior art, the utility model provides a be suitable for production line of steel slag treatment's horomill crouches through increase deironing, selection iron module on the production line, can effectively improve the production efficiency of horomill, reduces the iron enrichment in the horomill system, promotes horomill production efficiency, and reduce system's equipment and energy loss realize economic benefits.
The technical scheme of the utility model as follows:
the utility model provides a be suitable for production line of steel slag treatment's horomill, includes raw materials storehouse, horomill and selection powder machine, is provided with the lifting machine between horomill and the selection powder machine, and the selection powder machine includes qualified output and unqualified output, its characterized in that: a feeding conveyor belt is arranged at the feeding end of the raw material bin, and an iron remover I is arranged above the feeding conveyor belt; a conveying channel is arranged between the raw material bin and the horizontal roller mill, and a hot blast stove is arranged on the conveying channel; the unqualified output end of the powder concentrator is connected with the horizontal roller mill through a material returning conveying belt, and an iron remover II is arranged on the upper portion of the material returning conveying belt.
Preferably, a permanent magnet roller I is arranged on the feeding conveyor belt.
Preferably, a permanent magnet roller II is arranged on the material returning conveying belt.
Preferably, a dust collector is arranged at the qualified output end of the powder concentrator, and a finished product is output at the output end of the dust collector.
The use process comprises the following steps: the MFe content of the raw materials is generally less than 3%, and after the raw materials are subjected to iron selection through a feeding conveyor belt through an iron remover I and a permanent magnet roller I, the MFe in the raw materials can be reduced to be lower than 1%; the raw materials after iron selection enter a raw material bin to ensure the balance and stability of production and feeding; the raw materials in the raw material bin are dried by a hot-blast stove to meet the moisture requirement of horizontal roller milling; and the horizontal roller mill mills the dried raw materials, the milled raw materials are lifted by a bucket elevator and conveyed to a powder concentrator for sorting, and the raw materials with the fineness meeting the requirement enter a dust collector through a qualified output end to be captured and serve as finished products to be stored in a warehouse. The material that the fineness does not reach the requirement passes through unqualified output, circulates through the material returned conveyer belt and goes into the crocus mill until the fineness reaches standard. In order to reduce the circulating enrichment of raw material iron in the system, an iron remover II is arranged above the material returning conveying belt, so that the MFe of raw materials which are circularly fed into a mill and ground can be reduced to be within 3 percent, and the good working condition of the mill is ensured.
The beneficial effects of the utility model
The utility model relates to a novelty, simple, easy operation through utilizing the tubing pump to extract the quenching oil in cooling water and the quenching oil pond in the cooling water pond respectively, make cooling water at water-cooling cooler and cooling water pond inner loop, the quenching oil is at quenching oil cooling bath and quenching oil pond inner loop, realizes that the quenching oil flows the cooling. The temperature rise of quenching oil caused by the heat treatment of the high-temperature blank is effectively reduced, the heat treatment time is saved, and the processing efficiency is improved.
