Jenike & Johanson can help you meet your cement industry needs with retrofitting of bins to alleviate costly material flow problems, implementing new mass flow silos or stockpiles to maximize efficient gravity reclaim, or feeding of alternative fuels to the cement kiln or pre-heater calcination tower.
Raw Mix Preparation Raw Mix Optimization Raw Mill Optimization What is OptimizeIT Raw Mix Preparation? The consequences of poorly prepared raw meal are well known. High lime causes meal to be burned harder and refractory ITlife drops. High alkalines may cause cyclone blockage and restrict the use of the cement produced. Moisture content
Cement Production: Raw Meal Production in Steps Perfectly mixed, accurately fed without pulsation, and precisely weighed. The key word is quality! And this quality is achieved during cement production with exactly matched process steps. In the first stage, the raw meal is produced, as described below.
