1. 10% Less Energy, 20% Higher Yield – Maximize Efficiency!

◉  Our limestone shaft kiln features distinct zones: preheating, calcination, and cooling. Cool air enters from the base, cooling the product while preheating itself. This preheated air then enters the calcination zone, optimizing combustion and effectively cutting energy consumption.

◉ The incoming hot flue gas efficiently preheats materials from ambient to pre-decomposition temperatures. As it exits the shaft kiln, the flue gas temperature lowers to 170-300°C.

◉ Kiln shell features vertical masonry with 4 refractory layers, ensuring excellent insulation. Shell temp can be controlled at +60°C ambient, showcasing impressive energy savings.

2. Durable lifespan reduces downtime costs, ensuring uninterrupted production.

◉ Durable refractories extend service life. Material interacts via gravity settlement, not direct impact, minimizing wear on refractories.

◉ In typical conditions, the refractory material has a lifespan of 6 to 10 years.

3. Multi-fuel options

◉ Co-fired kilns utilize lump and coking coal as fuel sources.

◉ Gas-fired kilns utilize high-calorific value fuels like natural gas, coke oven gas, petroleum gas, and low-calorific value fuels including converter gas, blast furnace gas, calcium carbide furnace tail gas, semi-coal gas, and producer gas.

◉ Oil-fired kilns utilize liquid fuels like heavy oil and diesel.

4. Compact footprint, saving valuable floor space

◉ Vertical design of the shaft kiln.

◉ Efficient vertical feeding via single-bucket hoist at steep angles; conserving valuable space.

◉ Efficient layout, each zone optimally organized for space conservation.

5. Low investment

◉ Reduced machined parts in the kiln's steel structure for lower processing costs.

◉ Simple setup, minimal masonry complexity using refractory materials



Our vertical shaft kiln has a successful track record with hundreds of companies across various industries, including but not limited to Steel, Mining, Cement, Limestone Development, Chemical, Coal Group, Railway Equipment Manufacturing Materials, New Materials, and more.
