Slag Dry Granulating Thermal Insulation Buffer Electric Furnace

The slag dry granulating thermal insulation buffer electric furnace is a piece of high-efficiency, energy-saving and environment-friendly industrial thermal equipment specially developed for the harmless treatment, resource utilization and waste heat recovery of high-temperature molten slag generated in metallurgy, chemical industry, building materials and other industrial production. It integrates dry granulation, thermal insulation buffering and electric heating regulation, and provides a reliable technical solution for green and low-carbon transformation of industrial slag treatment.

Working Principle


This equipment takes high-temperature molten slag as the treatment object, and abandons the traditional water quenching wet granulation process to realize the whole dry operation. Under the action of the internal mechanical or pneumatic granulation mechanism, the high-temperature molten slag is dispersed and crushed into uniform solid particles rapidly.

Equipped with a professional thermal insulation structure and electric temperature control system, the furnace body can maintain a stable high-temperature environment, playing a role of thermal buffering. It avoids the rapid temperature drop of slag particles, prevents slag agglomeration and bonding, and ensures the continuity and stability of granulation. Meanwhile, the electric heating component provides auxiliary heat compensation, so that the slag can maintain the appropriate temperature required for granulation and subsequent waste heat recovery, and the waste heat of high-temperature slag can be efficiently captured and converted into available energy such as steam and hot water.

Main Structural Features

Dry Granulation Module: The core execution unit adopts a precision granulation structure, which can adapt to the physical properties of different types of molten slag, and produce slag particles with uniform particle size, good activity and high utilization value, laying a foundation for the subsequent production of cement admixture, concrete aggregate and other recycled products.
Thermal Insulation Buffer Furnace Body: It uses high-performance refractory and thermal insulation materials, with excellent heat preservation performance and low heat loss. The buffer space inside the furnace can adjust the residence time of slag, balance the fluctuation of slag incoming flow, and match the rhythm of front-end smelting and back-end collection and transportation.
Electric Heating & Temperature Control System: Driven by electric energy, it realizes accurate and stepless adjustment of temperature. Equipped with an automatic control system, it can monitor key parameters such as furnace temperature, granulation speed and slag flow in real time, automatically adjust operating indicators, reduce manual intervention, and improve operation stability.
Closed & Environment-Friendly Structure: The whole equipment is designed with closed sealing, which can effectively control dust emission and avoid secondary pollution. There is no large amount of waste water and waste residue generated in the dry process, which conforms to the national environmental protection and energy conservation standards.

Performance Advantages

Environmental Friendly: Completely get rid of the dependence of traditional slag treatment on a large amount of water, eliminate the generation of waste water and harmful water vapor, reduce dust and noise pollution, and meet the requirements of clean production.
High Resource Utilization Rate: The dry granulated slag has stable quality and high potential hydraulic activity, which can be widely used in building materials, road construction and other fields, realizing the complete resource utilization of industrial solid waste.
Energy Saving & Waste Heat Recycling: The thermal insulation buffer structure reduces ineffective heat dissipation, and the electric auxiliary heating is precise and controllable. Combined with the matched waste heat recovery device, it can recycle high-quality waste heat, reduce energy consumption of enterprises and improve economic benefits.
Strong Adaptability & High Stability: It can be applied to blast furnace slag, steel slag and other industrial molten slag, with flexible operation, strong anti-interference ability, and can realize continuous and stable operation for a long time.
Intelligent and Automated: With integrated automatic control, it supports data recording and remote monitoring, which is convenient for daily operation and maintenance, and helps enterprises realize intelligent management of slag treatment.

Application Scope
This equipment is mainly used in the metallurgical industry such as iron and steel smelting, as well as the high-temperature slag treatment links in chemical engineering, non-ferrous metal smelting and building materials manufacturing. It is an ideal supporting equipment for industrial enterprises to achieve solid waste reduction, resource utilization and carbon emission reduction.
