On March 17, 2026, Lead Equipment officially shipped its independently developed dry mix gunning machine for refractory. This blue gunning machine, with a maximum displacement of 3 m³/h, will bring a revolutionary change to the refractory construction field with its superior performance and environmentally friendly characteristics.


The dry mix refractory gunning machine employs an advanced rotor-type feeding system, achieving precise matching between material conveying and water jetting. Its unique pre-wetted nozzle technology reduces the rebound rate from the industry average of 25%-30% to 10%-15%, significantly reducing material waste and construction costs.


Four Core Advantages:
1. High-Efficiency Spraying: Breaking through the limits of traditional construction, achieving 6 times the efficiency of manual masonry, with a single spray thickness of 50-200mm, easily meeting the rapid spraying needs of large equipment such as blast furnaces and converters.
2. Flexible Adaptability: With a body width of only 700mm, it can operate deep into furnaces through narrow passages; the 360° rotating nozzle design perfectly adapts to various irregular working surfaces, covering the entire metallurgical, building materials, and chemical industries.
3. Economical and Environmentally Friendly: Dry mix spraying technology saves 80% more water and increases material utilization by 30% compared to traditional wet methods, bringing significant cost and environmental benefits to users.
4. Intelligent Operation and Maintenance: Equipped with a cloud-based data monitoring system, it analyzes equipment operating status in real time, enabling preventative maintenance, extending equipment life by 30%, and reducing operation and maintenance costs by 40%.


Dry mix refractory gunning Lead Equipment's machine boasts comprehensive application scenarios, serving as a versatile tool in the refractory spraying field. It has been successfully applied to:
Metallurgical Industry: Online thermal spraying of converters at Baosteel Group, and blast furnace lining repair at Ansteel Group
Building Materials Industry: Routine maintenance of cement rotary kilns at Conch Group
Chemical Industry: Rapid repair of cracking furnace linings at PetroChina
Non-ferrous Metals: High-efficiency spraying of refining furnaces at Jiangxi Copper


To ensure construction safety and quality, Lead Equipment provides comprehensive technical support to its clients:
