Rotary Kiln Calcined Limestone Turn Key Solution
The quality of lime produced by the rotary kiln is stable, the output of a single kiln is large, and the maximum daily output can reach 2200t. Lime rotary kiln can directly calcine fine-grained limestone of 10-50mm. The rotary kiln can directly use pulverized coal as fuel, and it can support a wide range of fuels.
Solid fuel: coal, coke, etc.
Liquid fuel: heavy oil, kerosene, diesel, etc.
Gas fuel: liquefied petroleum gas, producer gas, natural gas, etc.
Other types of fuel: Electricity.

How to Select a Suitable Lime Kiln
The selection of the lime kiln project needs to comprehensively consider the influence of various factors. We need to comprehensively consider factors such as fuel resource utilization, project static investment, product quality, and lime kiln operating costs. At the same time, it also needs to combine its own fuel conditions and consider the requirements of the local environmental protection department for a low-carbon economy and sustainable development.
Total investment cost. Choose the right kiln type according to the investment cost.
Site and production scale. The floor area and the number of auxiliary equipment of different kilns will be different and can be configured according to the actual situation.
Requirements for product quality. Depending on the end use, the demand for finished lime quality varies. The quality of lime produced by rotary kilns and different types of shaft kilns will also vary. The right type of lime kiln solution needs to be configured under the guidance of an expert.
