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.

A huge quantity of implant designs with varied size, shape, materials, and features have been developed successfully [5].
In this investigation, the mechanical properties of the materials, such as Poisson's ratio and Elastic Modulus, were standardized, and all materials were assumed to be isotropic, homogeneous and linearly elastic.

The Production Scheduling Problem of Aluminum Casting Based on Theory of Constraints Peng pin1,2,a and Chen enhu2,b 1Business School of Central South University,Changsha,Hunan,china 410083 2Jiangxi University of Science and Technology,Ganzhou, Jiangxi, China 341000 aPengpin@126.com, bchenenhu87@163.com Key words: Aluminum casting; Theory of Constraints; Production scheduling Abstract.
The holding furnace not only removes the gas and slag, but also plays a buffer role of post-melting for molten aluminum which helps to avoid the long melting time of furnace and ensures the continuous operation of casting machine. 3) Scheduling of bottleneck process Aluminum production scheduling should focus on strengthening the management of melting and select the appropriate production scheduling rules according to the different optimization goals and production rules to ensure melting the molten aluminum sent from electrolysis process completely, minimizing non-commissioned materials in the casting process and reducing the ingot inventory.

Introduction Zinc oxide is an important material with applications ranging from the fabrication of Ultraviolet (UV) optical detectors to photovoltaic devices [1,2].
An important limitation of this material for photovoltaic application is that it is only sensitive to the UV region of the solar spectrum.
