2.5*50m Cement rotary kiln

Introduction:
Raw materials extraction (mining) → crushing→ raw materials storage and pre-homogenization (ball mill) →raw material homogenization and storage, calcinations (raw material enter into rotary kiln after pre-heater in cyclone tube, calcinated to clinker) → cement grinding (mix other chemical material according to cement quality to grind) → cement storage and transportation
This is a simplified process of cement production. Our company can supply almost all the equipments in all the necessary section of this line. We can also provide unique solution to our customer.
Cyclone preheater is suitable for all kinds of kiln type supporting the use, Our Researcher developed ***0 tons of decomposing furnace with a magnitude of five suspension preheater. Preheater sized cement can be widely used in the newly built and renovation. Grate type cooling machine is a sudden cold type cooler, its principle is: with blower, will lay the ChuiLengFeng in grate board into layer of clinker to sudden cold, make °C plunged by 1,**0 clinker temperature of **0 °C below, the cooling of the large exhaust except for secondary air kiln.
Cement in our country is full-fledged development, cement equipment after the development direction of how to judge? Cement as now the most important materials of construction of its investment prospects are bright, the market demand is huge. As people life quality increasingly improved and all of their quality of life of the demand is higher and higher, buildings as the main place of production and life of people. The city of new cement is indispensable product, it has the broad market, in the vast market in the quality of the people will value, focuses on the quality at the same time also must yield, in the increasingly competitive today, how to choose a high quality high yield of production equipment is a primary problem. Because our country started than western developed countries to much later than in development of equipment to lag behind other developed countries, but we have the world's largest market, plus increased this year to state this aspect of the r&d makes domestic cement production equipment made great breakthrough, broke the overseas for technical monopoly. Greatly reduce the cost of investment is the huge market benefit more feminine. Therefore said to cement of investment prospects are bright, the market is the largest r&d power. Both are mutually promote mutual benefit.
Cement kiln maintenance mainly include playing kiln skin, demolition brick, masonry and cleaning. In order to try and shorten the stop time, it is to be in commonly kiln kiln, ****2 hours after cooling make skin and dismantle brick kiln stove temperature, then will be at *0oC above, thus playing kiln skin and dismantle tiles are in high temperature and high dust environment. According to common sense, and generally do not want to diesel engine drive equipment in high temperature and high dust under the conditions of use, because of diesel engine, and high temperature resistant not high dust will paste die air filter and radiator, cause failure frequency, the influence dozen brick homework.Under the influence of size and spake, general bridge is narrow, the machine by bridge through Bi cold machine best VIP car separation. Driving small excavators through the bridge cause people to car fall into the Bi cold machine malignant accidents at home and abroad have also been reported. Demolition brick and playing kiln is through hydraulic hammer skin to breakage, inevitably have crumbs jumped splashing kiln and the skin, in order to prevent chunks personal safety accidents, hope the operator to stay away from the coolie, don't sit on the machine can't avoid fixed. In order to enter the smaller spake, and do not want to of kiln hoods conduct additional transformation, asked to play the width and height of the brick machine is small, the weight should be light. At the same time of hydraulic hammer impact power wants big, with quick finish the homework, but also to play moving kiln head castable. Demolition brick kiln skin can be quickly dozen contrangle dismantle brick, but cannot damage cylinder. And this requires hydraulic hammer impact energy and frequency kiln adjustable steplessly. The machine must be considered in the design of high temperature and high dust circumstances and reliable operation, low failure rate, using low cost. Therefore, the international common practice is no longer the diesel engine driven engineering machinery used in rotary kiln leather down within dozen brick.
Cement kiln / cement mill / cement production line / Cement Equipment can be widely used in the newly built and renovation.
1.1 Cylinder by welding sliping structureWelding sliping structure can improve the cylinder force situation, reducing mill canister weighed, facilitating tube system build, manufacturing quality easy control as well as reducing equipment manufacturing cycle etc, and will become the large tube mill barrel structure development direction, and comprehensively will replace hollow shaft and casting roller ring structure form.Adopt sliping supporting mill barrel can greatly reduce get machine supporting center distance, make mill barrel bending moment, obviously decreased compared YuZhongKong shaft structure, the maximum stress the same circumstances, mill barrel plate thickness can reduce ~ *0%. Add sliping part of the weight of ease, canister weighed significantly reduced. While reducing the equipment configuration dimensions. Connect sliping adopts thick plates welded together, make the mill barrel manufacturing difficulty reduced. Thick plate quality can be controlled by NDT, welding quality of sliping through has rich manufacturing experience of technicians and factory complete welding process is effectively controlled and guarantee.

1.2 Flat structure baseSliding shoe bearings adopts the originality of one-piece plate structure base. Make sliding shoe bearings with installation is simple, convenient maintenance, sliding shoe covers sealing effect of simple structure, good advantages .

1.3 Composite wear-resisting steel liningEnter, discharging device, return feeder and drying storehouse adopts has good abrasion resistance of composite wear-resistant steel lining, enormously increased its for material wear washouts, service life than ordinary steel up *0 times above.

1.4 The overhanging the cantilevered drying storehouseUsing the overhanging the cantilevered drying storehouse, thinning the drying storehouse cylinder thickness, improving grinding storehouse cylinder of stress condition, thus enhancing the safety factor of grinding machine, reduced the mill weight.

1.5 High-pressure thin oilSliding shoe bearings lubrication adopts a high-pressure dilute oil, both simplified site equipment layout, convenient operation and control and also reduces the equipment manufacturing cost .
