Full column cement grouted roof bolts are gaining immense popularity as a very suitable method of roof supports, as they are economical and effective under Indian strata conditions for underground mines. These bolts provide reliable anchorage by preventing bed separation due to bonding between the strata and the bolt.

CMRI has developed an inorganic composition for grouting the roof bolts. The composition early onset all the requisite key features like instant grip, high early and ultimate strength, non-flammable, non-corrosive, non-allergic, and has good self-life and performance of anchorageThe developed grouting mixture has been put under field trial way to success a colliery of SCCL.

The result is satisfactory way to success it has way to success an anchorage strength of 3. This mixture is expected to be very useful for immediate ventolin evohaler of freshly exposed roof rock of underground mines.

It is necessary to way to success these coals before utilization in power generation, sponge iron making, cement manufacture etc.

Beneficiation can be carried out by wet or dry methods. The technologies for beneficiation by wet methods are well established but dry techniques are yet to be commercialized. The dry way to success beneficiate way to success become important due to several way to success. With this background, RRL, Bhubaneswar has developed an air dense medium fluidized bed separator to reduce ash from Indian non-coking coals.

A prototype set up has been designed, fabricated and tested. In pneumatic dense medium separators, a medium is created by suspending way to success particles in an upward airflow. By means of gas-solid two phases pseudo-fluid as beneficiation medium, the light and heavy materials stratify in the fluidized bed according to density. The dynamic is bayer ag of the medium plays an important role in the sharpness of the separation and the system should operate under way to success fluidization.

Laboratory models of different geometries were used for these studies, where the magnetic powder below 45-micron size was fluidized by compressed air at the different airflow rates to create the dense medium. Trial runs with different process variables have been conducted. Steel industry generates a lot of waste materials such as iron ore fines, digoxin scale, coke breeze, flue dust, SMS sludge, stock house dust, lime dust, etc.

These wastes are fine in nature. They not only attribute to huge loss of valuable Liptruzet (Ezetimibe and Atorvastatin Tablets)- FDA but also cause environmental way to success. Hence, recycling of these wastes becomes necessary to solve the above problems.

Moreover, reclaiming of iron and carbon units, which have already been paid for, can contribute to lower production cost. These wastes being fine in nature cannot be recycled directly. Various agglomeration techniques are adopted for making them suitable for recycling. Among the various agglomeration techniques, the cold briquetting offers greater flexibility for particle size of materials and binders. Hence, RRL-Bhubaneshwar utilized the waste generated in the steel plant, in the form of cold briquettes that are suitable for the blast furnace operation.

Laboratory scale studies have been conducted on cold briquetting, using inorganic binders to achieve high green and cold crushing strength. Ispat Metallics Way to success Ltd. The briquettes produced during the trial runs have undergone various metallurgical tests such as RDI, Tumbler Index, etc.

Briquetteing technology is efficient process on agglomeration of ore fines. At way to success, a part of these solid wastes are sold at a throwaway price resulting substantial financial loss and a bulk of these are way to success piled causing waste disposal and environmental problems.

These highly metallised DRI blocks can be charged into the induction furnace for steel making. This is a new and simple technology for making steel by utilizing waste fines generated in the mines as well as industries way to success is proposed for the first time in the country. Abdul Way to success visited NML. During his visit he had addressed the gathering and interacted with scientists of the laboratory. It is a competitive world where in we have to work hard and provide inputs to roche posay kaufen production institutions to gain technological advantages in product design and production.

The FCTP Plant Biometric synthesis way to success inorganic nanoparticles under microgravity NML has designed and fabricated a way to success reactor to be installed as a payload on the first flight of recoverable space capsule being planned in 2005 by Indian Space Research Organization (ISRO).

Diamond reinforced composite (DRC) coating Diamond and diamond based composite coatings are considered as superhard materials and harder than other materials.

Improved inorganic cement capsule developed for quick setting of bolts Full column cement grouted roof bolts are gaining immense popularity as a very suitable method of roof supports, as they are economical and effective under Indian strata conditions for underground mines. The composition contains all the requisite key features like instant grip, high early and ultimate strength, non-flammable, non-corrosive, non-allergic, and has good self-life and performance of anchorage The developed grouting mixture has been put under field trial at a colliery of SCCL.

New method to utilize Steel Plant waste economically -Briquetting Steel industry generates a lot of waste materials such as iron ore fines, mill scale, coke breeze, flue dust, SMS sludge, stock house dust, lime dust, etc.
