The information window mine explosion-proof micro DC air compressor was born by Shandong Coal Science Research Institute and Jinan Air Compressor Factory. The flexible and explosive mine-type micro-DC air compressor jointly developed by Zhangzhou Mining Group Corporation Xinglongzhuang Coal Mine can provide compressed air for various mining pneumatic tools. It effectively solves the problem that some places in the coal mine have no wind source or inconvenience caused by the air duct cable, which has affected the use of the pneumatic tools, and has passed the technical appraisal.
The main features of the DC air compressor are as follows: 0Using the power supply of the 5 explosion-proof special-type battery motor car, avoiding the explosion-proof DC-type power-off and voltage regulator for the extraction and pulling of the cable mine, so that the air compressor exhaust temperature and exhaust pressure are super Automatic shutdown after the limit 3 uses a dual gas storage tank structure. Improve the stability of the equipment; the design uses a direct-coupled flexible coupling 1 generation tape drive. Both meet the requirements of the speed. The efficiency is improved; the vent valve is provided on the pneumatic automatic switch to reduce the load when the motor is restarted. Li Jianfeng Wennan coal mine thin coal seam mining to achieve mechanization Shandong Xinwen Mining Group Wennan Coal Mine in the thin coal seam mining process test application of plow. Received 1 good effect.
The plow is a kind of coal mining machine designed according to the characteristics of the thin gauge. It has the characteristics of fast running speed and is suitable for medium hardness. The application of the top and bottom plates to smooth the gently inclined coal seam with a simple geological structure. This technology has achieved good results in the test application of Wennan Coal Mine, and the mechanization level of mining in thin coal seams will be greatly improved.
The 15-story coal mining height of the main coal seam in Wennan Coal Mine is 1.64, of which the upper coal has a thickness of 76, which is mainly bright coal and asphalt luster. The thickness of the block-shaped clamp is 52. In the past, the blasting of the coal was used. Has been forced to stop mining. The mine decides to use only the upper coal for the rational use of coal resources to reduce resource losses, and adopts the plow mining process. The process has been tested for more than three months. Success has not only changed the non-minable coal seam into a recoverable coal seam, but also prolonged the service life of the mine, and the efficiency of the human tons is not reduced. The calorific value of coal has increased from less than 17% to the current 29.3%. 8. Increased by nearly 50. Stabilized coal prices and improved product reputation. Compared with the increase, it also greatly reduces the labor intensity of workers. For the mechanization of thin coal seams, we provide experience in Ding, Zhou Fenggaobin metal wear self-healing materials, and metal wear self-repair materials with independent intellectual property rights. Recently, it was published in Harbin, Heilongjiang Province. It is only necessary to add an extremely small amount of such ultrafine powder material to the carrier lubricating oil. The metal friction surface can be reached quickly. Automatically repair the worn parts. So that all kinds of mechanical equipment will be overhauled for life. This is a major breakthrough in the research and development of friction reduction mechanism in the field of tribology in China, and it is the second revolution in the maintenance and repair of mechanical equipment.
The metal wear self-healing material is an ultrafine particulate material composed of various complex components such as magnesium hydroxysilicate. It is not a chemical replacement reaction occurring at a portion of the heat energy, and a cermet layer having excellent anti-wear properties and a large increase in microhardness is produced.
Experts detect it. This material allows the bearing to maintain optimum dimensional accuracy. Increase the rated service life by more than 21 times and increase the service life of the cutting tool by more than 5 times. The life of special steel is more than doubled.
At present, Harbin Shenglong New Material Technology Co., Ltd. has built China's first metal wear self-healing material production line in Harbin. The Jianxin 525 Continuous Shearer Bolting Machine Company has developed a type 525 continuous miner bolting machine, which was recently exhibited at the exhibition. It is regarded as a major breakthrough in the application of its advanced technology in continuous miners. There are 1 spiral warping cutters on the left and right sides of the machine. In the rear track 1 walking mechanism, the Shi’an section is scraped, and the conveyor is equipped with 2 bolts and eye-mounting machines. The quality of the 525 continuous miner bolting machine is 6,1. The cutting depth is not limited. The height of the excavation or the height of the mining is 91.41829. Equipped with an efficient dust removal system. The track shoe is wide. 9. Grounding pressure In terms of safe operation, the operator of the bolting machine can control the operation mode of the continuous miner. Ensure the safety of the support work. Also. The polelayer is also equipped with an automatic temporary roof support system. Effectiveness guarantees the safety of personnel. Songbai strong wishes
Manufactured by casting and melting is called cast Steel Ball. Production process is:Raw material chemical composition and optional proportion-- Melting and pouring-- Oil quenching-- Temper-- Polishing. Casting chrome grinding balls are widely used in thermal power, and ultra-fine powdering of cement, metal ores and coal slurries. Cast grinding balls have excellent toughness, preserve their circular shape, low wear and tear, and a low crushing rate. It is widely used in a variety of dry mills. Casting chrome grinding balls include lower chrome, medium chrome, high chrome and special High Chrome Cast Ball.
