Everything about the cement industry

  The most important points of lubrication for cement industry There are 4 types of lubricants: Oil, Grease, Penetrating Lubricants, and Dry Lubricants. The 2 most common lubricants you'll be dealing with daily are oil and grease, however, your facility will still be using dry and penetrating lubricants.

  Let's get to know the stages cyclone Preheater Cyclone Preheater Introduction: The cyclone preheater is the core equipment of the new dry process cement production technology. It uses the suspension preheating method to preheat and partially decompose the raw material to shorten the length of the rotary kiln, and at the same time make the raw material and the hot gas flow in the kiln full. Mixing, improving heat exchange efficiency, thereby achieving the purpose of improving the production efficiency of the entire kiln system and reducing the heat consumption of clinker firing. Cyclone Preheater In Cement Plant Cyclone Preheater Performance Advantages Cyclone preheater can make full use of the heat in the kiln, reduce the heat consumption of clinker burning, reduce the floor space of the burning equipment, fully utilize the heat in the kiln, reduce the heat consumption of clinker burning, and reduce the floor space of the burning equipment At present, the five-stage cyclone preh

   Introduction to cement Raw Materials Raw materials used for manufacturing of Portland cement are found naturally  in  the  earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale. Let’s understand the various types of cement raw materials used in the cement manufacturing process. Limits of Main Chemical and Oxide Constituents of OPC are Given in this Table Functions of the Constituents of OPC Lime It is the main constituent used in cement manufacturing. It is responsible for imparting the cementing property to cement. An excess quantity of lime causes expansion and disintegration of the cement. Deficiency of lime causes decreased strength and the cement sets quickly. If it is used in the right proportion, it makes the cement sound and strong. Thus, lime can drastically change the properties of ce

Coolax Cooler, design and operation CIS - Controlled Impact System CFG - Controlled Flow Grate RFT - Reduced-Fall Thru Grate   The COOLAX high efficiency  grate cooler has greatly improved heat recuperation com-pared with traditional coolers. The efficiency of a grate cooler may be characterized in terms of cooler loss, this being the amount of clinker heat not recirculated to the pyro process. Traditional cool-ears have a loss of about 140 kcal/kg clinker. The COOLAX has a loss of only 95-100kcal/kg clinker. In the heat recuperation zone (CFG zone)the cooling air is supplied direct to the grate plates through a system of ducts and hollow beams instead of via an under grate compartment as in conventional coolers. On l ya small portion of the air enters the clinker bed from the under grate compartment This is the sealing air. The CFG zone is divided into sectors sup-plied with cooling air from separate fans. These ctors are subdivided into smaller segments each with their own adjustable

Clinker Coolers Introduction for cement industry In the beginning, I offer you the simplest information about Clinker cooling is achieved by passing air streams through the grates. Due to an oscillatory movement, the grates cause the  flow and the spreading of the solid material. The thickness of the bed depends on the speed of the grates as well as on the mass rate of clinker  in  the  kiln  outlet.  Consequently  a  heat exchange is  performed between clinker  and air.  A part of the hot air volume is introduced inside kiln as secondary  air  and  used  for  the  fuel  combustion, while the  rest is  evacuated towards the  de-dusting filter characterized as exhaust air. Efficiency of the cooler  includes  two  operations:   (i)  The  heat recuperation from the clinker entering to the cooler, (ii) the cooling of the clinker. A fast cooling, i.e. a low  clinker  temperature  in  the  installation  outlet, contributes to an increase of the product quality See More Information Download 

CF Raw Meal Silo How it works  The CF (Controlled Flow) silo is a continuously operating system for homogenization and storage of cement raw meal, where the material is extracted simultaneously at different flow rates from a number of outlets in the silo bottom. The CF system, including suitable kiln feed equipment, ensures stable kiln feed composition at minimum power consumption and investment cost. The efficient performance of the CF homogenizing silo results in stable kiln operation so that changes in kiln speed or firing rate are rarely needed and stable coating in the kiln is maintained. In order to ensure high homogenization efficiency, all the raw meal in a silo must be kept in constant movement towards the outlets. Furthermore, the raw meal must pass through the silo in flow zones with different residence time. The CF silo complies with these demands. It extracts raw meal at different rates from several outlets in the silo bottom and mixes the stream from these outlets. The CF

 Want to know How Steel Cord Conveyor Belt Splicing STEP BY STEP The belt is one of the most important parts of a conveyor system when it comes to design and investment costs. Due to logistic reasons, the belt can only be transported in segments to the conveyor system, limited by weight or length of the individual segment. The splicing is done directly at the system. In the splice, tensile forces are transferred through the core rubber and not via tension member. This fact makes a splice the weakest point of a conveyor belt. The tension member of a belt can consist of textile fabric or steel cords, depending on the tensile strength of the belt. Steel cord conveyor belts can reach a nominal belt breaking strength up to  10.000 N/mm. Fig. 1 shows the general structure of a steel cord conveyor belt Fig. 1. Steel cord conveyor belt Fig. 1. Steel cord conveyor belt  The steel cords are covered in core rubber and form the carcass of the belt which is covered by top and bottom cover. The bott

 Preheater Cyclone Modification and Main Components     Low- pressure drop   Reduction in pressure drop of the gas is partly achieved by large inlet area and outlet area for a given cyclone size and partly by providing more space for the gas flow in the top part of the cyclone. Due to this geometry the inner pipes can be shorter to decrease the resistance in the system and in the same time still the separation efficiency of the cyclone will achieve the needed rate. Pressure drop will be between 5 to 15 mbar depending on dimension of the cyclone and on its type but modern preheater are designed with total pressure-  drop of 35 m bar through out the total preheater. -          Preheater string consists of four or five or six cyclones called stages and these cyclones are a reversed flow cyclones with a vertical axes     As a rule the higher the number of preheater stages, the lower will be the drying capacity of this modern kiln system -with cyclone preheater and Precalciner. -          E
