superheated steam jet mill utilizing waste heat energy

Superheated Steam Airflow Mill Overview

Superheated steam airflow mill in the crushing process, not only can efficiently refine the material, but also make full use of the existing energy, suitable for industrial waste heat recovery and low-temperature power generation after the use of steam. Compared with the traditional air mill, superheated steam air mill has stronger crushing capacity and energy saving effect, is a kind of high efficiency and environmental protection equipment with broad application prospects.

Working Principle of Superheated Steam Airflow Mill

Utilizing the high temperature and high pressure characteristics of superheated steam. Superheated steam is injected into the crushing chamber through the concentric nozzle to produce high-speed airflow. These high-speed airflow to accelerate the material particles, so that the particles of violent collision and friction, and then the material will be crushed to the required fineness. The crushed material enters the classifier, and through the airflow classification, the qualified fine powder is separated from the crushing system and collected through the collection system at the back end. Unqualified coarse powder is then returned to the pulverizing room to continue grinding until it meets the requirements. The whole process is carried out in a fully dry environment, and the steam is kept in a superheated state, thus improving the efficiency of energy utilization.

Characteristics and Advantages of Superheated Steam Airflow Mill

• High energy utilization efficiency: superheated steam airflow mill can make full use of industrial waste heat or low-temperature power generation after the generation of steam, to avoid the waste of steam, thus effectively reducing the cost of powder processing.
• Energy saving and environmental protection: through the use of existing steam or low-temperature steam, the energy consumption in the crushing process is greatly reduced, compared with the traditional air mill, the use of superheated steam air mill powder processing costs for the air mill is only 1/5 to 1/8.
• Strong crushing capacity: conventional air mill design line speed is usually 400m/s to 600m/s, while superheated steam mill crushing intensity can reach 1000m/s, providing stronger crushing force, to adapt to a wider range of material crushing needs.
• In line with energy saving and emission reduction policy: the design of superheated steam mill is in line with the current national policy requirements for energy saving and emission reduction, can effectively reduce energy consumption, while reducing environmental pollution. Its use of waste heat for production, reducing the dependence on high-energy resources.
• Strong economy: through the recovery and utilization of low-grade energy, can significantly reduce production costs, and has a high economic efficiency, suitable for use in industries that require a large amount of steam.

Application Areas of Superheated Steam Gas Flow Mill

• Mineral and metal processing: used for ultra-fine crushing of mineral materials such as ores, metal powders and so on. The materials that can be processed by superheated steam air flow mill include ores with high hardness, such as quartz, gypsum and so on.
• Chemical industry: in the production of fertilizers, pigments, ceramics, plastics and other chemical products, it can effectively crush raw materials, improve the uniformity and fineness of the product, and it is suitable for chemical powders that require higher powder fineness.
• Pharmaceutical industry: used in the crushing of drugs, is the need for precise control of particle size of the fine powder drugs, such as traditional Chinese medicine extracts, natural plant powders and so on. Can meet the high standard requirements in drug production.
• Food industry: in the processing of food powder, spices, coffee powder, milk powder, etc., the superheated steam air flow mill can provide precise control of the fineness of the pulverizing effect, to ensure the quality and taste of the product.
• Environmental protection industry: for the treatment of waste and waste materials, waste materials such as slag, coal ash, etc. can be crushed into ultra-fine particles, which is conducive to resource recycling and waste reduction.
• The energy industry: in the thermal power plant or other energy fields, superheated steam air mill can be used to waste heat recovery system, the original emission of steam effectively converted into crushing power to reduce production costs.
