According to the calcination character of limestone, lime rotary kiln is specialized design for production of active lime. This type of kiln can work with vertical preheater and vertical cooler to achievethe advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc. Our products advantages: 1.According to the character of limestone and its calcination requirement, the structure of kiln inlet and outlet sections has been optimized. It can resolve the problem of material returning back to kiln inlet and the leakage of dust. 2.Evenly heating for limestone, low rate of less calcination and over calcination. Especially suitable for the high activity lime for steel making?? Technical configuration is optional: matched vertical preheater can use the high temperature from rotary kiln to preheating the limestone from room temperature to decomposition condition; matched vertical cooler can cooling down the high temperature of lime in the shortest time, and process can increase the activity of lime and also easy for transportation and storage. Lime kiln is mainly compose of driving device, supporting roller, catching roller, cylinder, kiln inlet, kiln outlet and sealing device. 1. 2-3 supporting points can guarantee the contacting surface between supporting roller and tyre is paralleled with axis line of cylinder during installation. 2.

Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials equipment category. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. Cement kilns are mainly used for calcination of cement clinker, divided into two categories: dry production cement kilns and wet production cement kilns. Metallurgical chemical kilns are mainly used for the magnetic roasting of lean iron ore in the metallurgical industry; oxidation roasting of chromium and nickel iron ore; roasting high alumina bauxite ore in refractory plants and roasting clinker and aluminum hydroxide in aluminum plants; roasting chrome ore in chemical plants And minerals such as chrome ore powder. Lime kiln (i.e. active lime kiln) is used to roast active lime and light-burned dolomite used in steel plants and ferroalloy plants. Rotary kilns are divided into variable diameter rotary kilns and through-diameter rotary kilns according to their appearance. According to their uses, they can be divided into cement rotary kilns, ceramsite sand rotary kilns, kaolin rotary kilns, lime rotary kilns, etc., according to different energy supply effects. It is a gas-fired rotary kiln, a coal-fired rotary kiln, and a mixed-fuel rotary kiln.

molecular sieve calcination technology - jinan, shandong, china - shandong tianli energy co.,ltd

Molecular sieve material refers to a crystalline aluminosilicate material. It is also called saturated zeolite or zeolite. The crystal structure has regular and uniform pores, and the pore size is on the order of molecular size. Because it only allows molecules with a diameter smaller than the pore size to enter, it can screen the molecules in the mixture according to size, so it is called molecular sieve. Molecular sieve materials can be used as solid adsorbents in the chemical industry, and can also be used for drying, purification, separation and recovery of gases or liquids or as cracking catalysts in the petroleum refining industry. Molecular sieve catalyst materials suitable for different catalytic processes have been developed.

There are two kinds of molecular sieve zeolite materials: natural zeolite and synthetic zeolite. Among them, the preparation process of synthetic zeolite is as follows: raw material mixing ---- granulation ---- sieving --- drying --- calcination --- packaging, in which calcination is a crucial technical link of the whole process. The dried molecular sieve will be put into the calciner for calcination to obtain the finished molecular sieve.

The rotary calciner is a kind of high-temperature treatment equipment which is transformed on the basis of the traditional rotary drum dryer, by changing its heat source supply method. The material enters into the rotary drum of the calciner through the feeder. An arch-shaped heating device (built kiln body) is set outside the middle section of rotary drum. The furnace is equipped with fuel burners or electric heating elements. The FBT (furnace box temperature)is adjusted by the burner flame or the current of the electric heating element which is controlled by the automatic control system , so that the material is calcined at a certain temperature, and the calcination time can be controlled by adjusting the rotation speed of the rotary drum. The processed material is discharged from the lower end by the inclination of the rotary drum.

In addition to catalyst calcination technology, Tianli Energy also has rich engineering experience in catalyst spray drying technology, molecular sieve flash drying technology and molecular sieve calcination technology.

impacts of karst phenomena on engineering properties of limestone foundation bed, ar riyadh, saudi arabia | springerlink

impacts of karst phenomena on engineering properties of limestone foundation bed, ar riyadh, saudi arabia | springerlink

Evaluation of mechanical and petrophysical properties of the karst limestone became essential to avoid future risks in the construction of new urban cities built on limestones. Therefore, this study aims to evaluate the impact of karsts phenomena on engineering properties of limestone foundation bed at Ar Riyadh in Saudi Arabia. Three hundred core plugs were obtained by rotary drilling at depths ranging from the ground surface to 20m collected from 24 boreholes in two sites: (1) karst limestone (KL) at Al Aziziyah district and (2) massive hard limestone (HL) at Hittin district in Ar Riyadh city, Saudi Arabia. Petrographic, SEM, EDX, and XRD analyses are used to identify the mineralogical composition and microstructures of limestone samples. The petrophysical properties included the ovendry density, P-wave, and porosity where the mechanical properties covered the uniaxial compressive strength (UCS), point load strength index (PLI), and rock quality designation (RQD) for the karst and hard limestone samples. KL is characterized by 17.11% total porosity, 14.71% water absorption, 32.1MPa UCS, 1.70g/cm3 ovendry density ( dry), 51% weathered RQD, 5.49MPa medium shear strength, and low modulus of deformation of the plate loading test. HL showed 11.63% total porosity, 9.45% water absorption 43.1MPa UCS, 2.50g/cm3 ovendry density ( dry), 78% hard to fresh rock affinity RQD, and 9.93MPa high strength and high modulus of deformation of the plate loading test. For the water absorption (%), KL at Al Aziziyah district showed a range of 12.8517.80% averaged 14.71%. HL at Hittin district varied between 7.04 and 11.29% with an average of 9.45%. KL proved to be dense with ovendry density ( dry) averaged at 1.70g/cm3 while HL showed very dense affinity of 2.50g/cm3. KL clarified a UCS range from 22.5 to 40.1MPa and an average of 32.1MPa while HL showed a range from 35.4t o 48.1MPa with an average of 43.1MPa. KL is moderately weathered with RQD average of 51% while HL showed a hard to fresh rock affinity of 78%. Point load test clarified a medium shear strength with 5.49MPa for KL and high strength of 9.93MPa for HL. Plate loading tests indicated low and high modulus of deformation for KL and HL, respectively. Results of petrographical analyses and XED of limestone samples showed that the strength parameters of samples mostly composed of micrite (mudstone/wackestone) and dolomite in hard limestone of Hittin district. In Al Aziziyah district (KL), the samples mostly consist of foraminifera and high amount of calcite as in karst limestone (wackestone/packstone). Rock mechanical tests with combination of fabric analyses have shown that strength parameters depend not only on the amount of karst but also on the amount of allochem. Major geomechanical differences between the two types of limestone provide the proper base for prioritizing areas to alleviate future risks and sustainable urban planning for decision makers. The karstic limestone, therefore, is considered as an acceptable foundation bed for light engineering structures. However, for heavy structures and buildings, improving the foundation bed strength by grouting, cement injection, and mat foundations is necessary to avoid future failure risks.
