Product Description Rotary kiln is a building material equipment category. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different processing materials. Cement kiln is mainly used for calcining cement clinker, divided into two major categories: dry cement kiln production and wet production cement kiln. Metallurgical and chemical kiln is mainly used for magnetization roasting of poor iron ore in the iron and steel industry of metallurgical industry; oxidation roasting of chromium and nickel iron ore; roasting of high-alumina bauxite ore in refractories plant; roasting of clinker in aluminum plant; aluminum hydroxide; roasting chromium ore in chemical plants And chrome minerals and other minerals. A lime kiln (active lime kiln) is used for roasting active lime and light-burned dolomite used in iron and steel plants and ferroalloy plants.Metal Industry Application In non-ferrous and ferrous metallurgy, metals such as iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, and niobium are used as smelting equipment for rotary kiln, and ores, concentrates, and intermediates are sintered and roasted. For example, in aluminum production, it is used to roast aluminum hydroxide into aluminum oxide; in ironmaking, it is used to produce pellets for blast furnace ironmaking; the foreign "SL/RN method" and "Krupp method" use it for iron ore. The direct reduction; chlorinated volatile roasting method using it to extract tin and lead and so on. In the beneficiation process, the roasting iron is magnetized and roasted in a rotary kiln, so that the original weak magnetic properties of the ore are changed to strong magnetism so as to facilitate magnetic separation. In the chemical industry, soda is produced in a rotary kiln, and phosphorus fertilizer and antimony sulfide are calcined. In the 1960s, LapPle et al. invented a new process for producing phosphoric acid using a rotary kiln. This method has the advantages of low energy consumption, low power consumption, no use of sulfuric acid, and the use of medium-low grade phosphate rock. It was quickly promoted, and the phenomenon of ring formation often occurred in the production of rotary kiln, and most of them were stopped by workers. But the impact on production and the increase in production costs have been eliminated. It can handle the ringing phenomenon very well.The main structureKiln sectionThe kiln head is a part of the rotary kiln, with a diameter greater than the diameter of the rotary kiln, and it is sealed by stainless steel fish scales and kiln. The main components are the inspection openings, coal injection nozzles, trolleys, and observation holes.Kiln sectionIt is the main body of a rotary kiln (rotary kiln), usually 30 to 150 meters long, cylindrical, with 3 to 5 rolling rings in the middle. Most of the cylinders are processed by the factory into 3 to 10 sections, which are welded after being transported by large trucks to the destination. The part of the rolling ring, also commonly known as the tire ring, is made of molten steel. The kiln body of the rolling ring is slightly thicker than other parts of the kiln steel plate because of the weight bearing. The supporting tugboat is also a part of the kiln body and the roller ring is correspondingly connected to the foundation. It is the bearing pillar of the entire rotary kiln. Usually a set of rollers consists of two idler rollers and two stop rollers. Rotary kiln should be covered with refractory bricks during normal operation.Kiln sectionThe kiln tail section is also an important part of the rotary kiln. The shape of the feed end is similar to the cover of a rotary kiln, and it is mainly responsible for feeding and sealing.Rotary kiln support frame1. The support frame of the rotary kiln can make our rotary kiln equipment more sturdy so that it will not shake and work stably during work.2. The support frame of the rotary kiln is mainly used to fix our rotary kiln equipment. When it is in use, it can prevent the deformation of our rotary kiln equipment. Everyone knows that if the rotary kiln equipment is operated improperly, it will have such a function. ;3. The rotary kiln bracket can facilitate the hoisting of our rotary kiln equipment, which is convenient for transportation.Preheating towerThe preheater is also called the preheater which is used to heat the material from the waste heat discharged from the rotary kiln before entering the rotary kiln. It is mostly a vertical structure. The principle is that the waste heat from the end of the rotary kiln is heated by the preheating tower filled with raw materials. Plus the preheat tower can effectively reduce energy consumption and improve the quality of finished products.CoolerCooler and preheater are the devices that cool the rotary kiln material quickly after cooling. It looks like a small rotary kiln. It is smaller and shorter in diameter. It doesn't need to lay firebricks and it is replaced by risers. The main role is to cool down the finished product quickly.conveyorConveyor belt is the material conveying device of rotary kiln. In the course of use, it often has various forms of damage, such as: edge delamination, fester, defect and cracking; Longitudinal longitudinal tear, deep scratch, hole, large area wear , covering plastic drum kits or peeling, joint defects and so on. Longitudinal tears are the most urgent, and the edges are the most common. Intrinsic defects in joints are difficult to avoid. The service life is most concerned after repair.The conventional high-temperature hot vulcanization process has poor repair effects for long-distance longitudinal tears, long-distance edge fester, and edge defects, and the rotary kiln is bulky and labor-intensive. The use of new materials in foreign countries to solve the problem of damage to the conveyor belt, Kester 90T high curing rubber repair cream or Forsorn rubber repair material repair. 90T has excellent adhesion, adhesion to all rubbers; excellent elasticity, elongation up to 300%; excellent anti-wear performance, abrasion resistance over heat-cured elastomer; anti-scattering performance, can be vertical or The top surface of the head smears 1 inch thick without scattering; 100% solids means no shrinkage, excellent chemical resistance, and resistance to a wide variety of chemical attacks. Forsorn is a new type of synthetic rubber product that can repair belts simply, quickly and for a long time. It has excellent abrasion resistance, impact resistance and long-term durability equivalent to extending the service life of the belt. main technical parametersModel Technical ParameterReducerMain Motor Suppport Quantity Weight(t) Rotate Speed(r/min)Slope(%)Capacity(t/h)Model Speed RatioModel Power(kw) Rotate Speed(r/min)φ1.6×360.26-2.6330.6-1.5ZL75048.57YCT250-4B221320/132347.5φ1.8×450.16-1.6241-4.5ZS110-580YCT280-4A301320/132380φ2.2×500.125-1.253.52-8ZS145-11160YCT280-4A451320/1323130.71φ2.5×500.62-1.863.57.5-15ZS145-7100YCT355-4A551340/4403167.5φ3×480.47-1.403.515-20ZS145-7100YCT355-4B751340/6003237φ3.2×500.398-3.9753.520-50ZL130-1640ZSN4-280-11B19010003263φ3.3×520.391-3.913.524-55ZSY500-2828ZSN4-315-08219010003280.8φ4×600.396-3.963.532-105ZSY630-35.535.5ZSN-355-09231510003487.5φ4.2×600.4165-4.1653.545-116ZSY710-35.535.5ZSN4-355-1235510003576.1
