The main products are ceramic inner tube for preheater, which are used in preheaters of new-type dry-process cement production lines as an alternative to nickel and chromium alloy steel and can realize chrome-free cement production. The products have been applied in over 200 cement production lines domestically, and the annual capacity is 300 sets.

The rotary kiln is the heart of a cement manufacturing plant. Cement kilns have all chemical ingredients. These. ingredients are at a broad range of gas temperatures from 100° to 1650°C. The emissions contain: High concentrations of alkaline solids, including sodium and potassium oxides; High concentrations of freshly created Calcium Oxide.

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

The three broad processes of cement manufacturing are: Raw milling — the preparation of the kiln feed. Calcining and burning or clinkering — the conversion process that takes place within the cement kiln and associated equipment. Finish milling — the grinding of clinker to produce cement. Raw Materials

Disclosed is a bypass system for use with off gases that have exited a cement kiln utilized in a cement making process. The bypass system is adapted to remove both NOx and volatile components that are present in the off gases while the off gases are in the bypass duct.

Temperatures – Cement kilns operate at 2500° to 3000° F; pre-calciners can reach 1800°F. The various stages in the preheater tower and the clinker cooler operate at temperatures up to 700° F. Rotary Feeder & Rotary Valve Applications in Cement. In most applications, no matter the industry, rotary feeders and valves have one or two functions.

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.

Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.

Stage 4: Burning . The raw mix is pre-heated before it goes to the kiln, which is heated by a flame that can be as hot as 2000° C.; The raw mix burns at 1500° C producing Clinker.; Stage 5: Grinding . The Clinker and the Gypsum are very finely ground giving pure Cement. Other secondary additives and material can also be added to make a blended cement.

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...
