Various countries list as the pulverized coal ash comprehensive utilization the national environmental protection, the building materials department's important matter.
In general, when research development use superfine pulverized coal ash material, must display its shape effect, the active effect and the micro aggregate effect three big effects as far as possible, achieves the improvement regeneration concrete workability, to enhance the intensity in order to and the durable goal. 1 Experimental material and plan basis 1.1 Experimental materials and instrumentation equipment The superfine pulverized coal ash enhancement engineering research, the thick aggregate uses completely regenerates the thick aggregate, abandons the basketball court concretes ground demolition take Dongyang some school as raw material (original concretes intensity rank C15, uses pebbles construction, gradation and service life, cement model and so on correlation technique material is unclear), after artificial becomes appropriately stave massive when changes over to the jaw type breaker to carry on is further stave, working procedures and so on sieving, graduation, clean to

Fig.3 Structure of the tube roller mill In operation, the ground materials were falling by gravity in a horizontal rotating cylinder body, uniformly distributed on the cylindrical inner surface of the cylinder by the action of centrifugal force,which formed the entrance end, with the rotation of the cylinder the material got into the grinder and grinding roller extruding channel, roll to the grinding material pressure by hydraulic system and pressure hydraulic system that caused by the friction does passive rotary motion, material in the extrusion passageway was promoted through a material guide device for an extrusion grinding operation.
After repeated extrusion grinding materials leaved grinder, and discharged from the chute.
Therefore,we must take both the equipments large scale and high energy saving into consideration, and combined the material science at this stage with excellent grinding theory achievements organically, to produce a large equipment could ensure the grinding efficiency, improve equipment station efficiency and service life, achieve the aim of resources comprehensive utilization.

Application of MEMS technology, the micropyrotechnic igniter are produced.The principle is based on the integration of the potassium salt of 7-hydroxy-4,6-dinitro-5,7-dihydrobenzofuroxanide (KDNBF) material within a micropyrotechnic igniter, which is produced by MEMS with 3 by 3 micro-igniter.
Micro-pyrotechnics can be defined as the integration of an energetic material into a multi-functional micro-system, for which the thermal, mechanical and chemical energy released by decomposition[8].
The variance of resistance on Ni-Cr bridges are less than 5Ω, but the variance of resistance on Al bridges are about 20Ω.Range and variance of resistance of Ni-Cr bridges are minor,which indicate that compatibility and homogeneity of resistance of Ni-Cr bridges are better than resistance of Al bridges. 3.Experiments The energetic materials of pyrotechnics are relatively unstable materials, which is easy to explosion and burning effect by exoteric energy.
