Lime Rotary Kiln

The lime rotary kiln, also known as the rotary drum kiln, is a widely used equipment for lime production. It has an advanced structure with a combined flake sealing at both ends of the rotary kiln, ensuring a leakage coefficient of less than 10%. It uses composite refractory materials to reduce radiative heat loss. The lime rotary kiln is a rotating device that is typically used to heat limestone and other raw materials to high temperatures, causing them to decompose into lime and compounds such as carbon dioxide. This process is known as lime calcination. In the lime rotary kiln, the raw materials are fed into one end of the kiln, pass through the high-temperature zone inside the kiln barrel, and eventually produce lime and other by-products at the other end.

Product Introduction

Performance Features

1. The advanced structure of the vertical preheater with low pressure loss can effectively improve the preheating efficiency. The decomposition rate of limestone after preheating can reach 20-25%, and it can directly utilize fine-grained limestone of 10-15mm.
2. The reliable combined flake sealing at both ends of the rotary kiln ensures a leakage coefficient of less than 10%. It uses composite refractory materials to reduce radiative heat loss.
3. The filling-type, zoned and ventilated circular or square vertical cooler allows the lime exiting the cooler to have a temperature of 800℃ + ambient temperature, facilitating transportation and storage. It also enables the preheating of secondary air entering the kiln to over 700℃, reducing the wear on moving parts and special materials.
