Derived from the classic 1856 design and upgraded by Halstec, the Hoffman Kiln is an intermittent circular sintering kiln with the characteristics of low investment, low fuel consumption and flexible layout, ideal for small & medium brick production projects and emerging markets.
Core Features
Wide raw material adaptability: Suitable for clay, shale, coal gangue, fly ash and other conventional raw materials
Low fuel consumption: Rational heat utilization, exhaust temperature only 100-120℃, fuel combustion heat fully used for brick preheating and sintering
Small investment: Low supporting equipment and steel consumption, reduce initial project investment
Simple operation & maintenance: No need for kiln cars, pushers or ferry cars, easy management and daily maintenance
Short construction period: Fast construction and commissioning, quick return on investment
Continuous production: One-time ignition, circular roasting without interruption, high yield and stable output
Unique Sintering Principle
Hoffman Kiln is a circular/elliptical long tunnel divided into multiple chambers, with fixed bricks and movable fire. The kiln is divided into preheating zone, burning zone and cooling zone, which move along the circular kiln path with continuous loading and unloading. Fuel is injected from the roof coal feeding hole, burns in the brick stack gap and generates heat for sintering; the air required for combustion is fully preheated by the cooling zone hot air, realizing ultra-high heat utilization efficiency.
Applicable Scale & Fuel
Land area: 20,000-30,000 ㎡
Fuel: Solid fuels (coal gangue, coal, fly ash, coke)
Suitable for small & medium brick production projects (8-30 million standard bricks/year)
