Bond Ball Mill Work Index is calculated as follows: Wib——Bond Ball Mill Work Index,kW·h/st; P1—— Test screen aperture,μm; Gbp—— the weight of new undersize material generated per rotate,g/r; P80——the aperture size which 80% product particles can pass,μm; F80——the aperture size which 80% feed particles can pass,μm.
During HPGR comminution the feed material is exposed to very high pressure for a short time.
The high pressure causes the formation of microcracks in the feed particles and generates a substantial amount of fine material [5, 6, 7].

In this paper, analysis the humus soil pellet which made by a foreign company by SEM-EDAX, release test of organic material by mass spectrometry.
Experiment Materials and methods 1.1Experiment Materials The humic soil pellet made by foreign manufacturers, the appearance of the pellet is gray cylinder, the average diameter is 25.0mm, long 55.0mm, volume is about 27.0cm3, the average mass is 23.0g, specific gravity is 0.89 and the average porosity is 68%. 1.2Experiment methods 1.2.1 Test on humic biological pellet release organic matters Take four beakers fill with 1L distilled water, control dissolveded oxygen content at 0.5 ppm, 1 ppm, 4 ppm and 8ppm, blown nitrogen through the rotameter to adjust the content of dissolved oxygen, while using Dissolved Oxygen Meter (Germany, WTW inolad pH / Oxi level portable) for real-time monitoring dissolve oxygen content in water to reach the set states; Added humic biological pellet into each beaker with similar quality, and volume when beakers dissolved oxygen contents were stable, detected and analyzed the release of material composition in each beaker after 24 hours fully released.
With the growth of the retention time of the release of weakly polar organic materials are increasing gradually.

Introduction With the development of society and economy, the transformation of power grid is imminent .traditional power grid is not suitable for industrial electricity requirements, therefore , China has proposed building a smart, reliable, cost-efficient, environmentally clean, transparent and open smart grid.with the development of the national economy, electricity has become the primary energy of the country. along with a rich people's material life, the improvement of living standards, Demand for electricity is growing. the current railway sector electricity management is too backward.
Locomotive power management fees is used to power, after meter reading, and then pay the way. this through a matrix, each column is provided with a table of locomotive, by writing partition table data and summary data control way is now standard method of electric charge ,And in this way increases the workload management.according to statistics, only the power sector reading team is very large, and human faults, low work efficiency, easy to cause the waste of material resources[1].
