Cement Rotary Kiln in Indonesia

Nowadays, the Indonesia’s government develops the construction of major infrastructure projects. As we know, the construction sector is sensitive to the GDP growth. So the significant development of construction industry leads to the great demand for cement. Indonesia produces various types of cement. The main type is ordinary Portland cement. Other types include special ones and mixed cement, for certain uses in relatively small quantity. In addition, the Indonesia government paid much attention to developing the cement industry. And they allow small cement companies to develop due the great gap between the demand and supply of cement. Every year, small cement companies order cement rotary kilns and other cement production machines from neighboring countries, especially from China.

Overview of Cement Rotary Kiln in Indonesia

Generally, cement rotary kiln is a long cylinder rotating about its axis once every minute or two. And the axis is inclined at a slight angle, the end with the burner being lower. Nowadays, over a billion tonnes of cement are made per year, and lime kiln equipment is the heart of this production process: their capacity usually determines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas-emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology. In addition, recycling the waste concrete has become a popular trend among cement manufacturers. According to technical process, the cement rotary kiln in Indonesia can be divided into dry process kiln and wet process kiln, and the former is widely used.

Small Cement Production Machines in Indonesia

In the cement industry, the small cement plant refers to the cement machinery with the capacity less than 200 tonnes per day. And the cement factory employs less than 100 workers. Of course, small cement plant is made up of small cement production machines. It is well known that at present levels of technology, it is economically feasible to build rotary kiln with a capacity of less that 200 tonnes per day. Therefore, vertical shaft kilns are appropriate for small cement factory. Typically, small cement plants are consisted of crushers, belt conveyor, hammer mill, bucket elevator, raw material silo, storage silo, ball mill, blending silo, vertical shaft kiln, and truck loading.
