磨粉

The motion state and grinding theory of milling medium in tube object of vibrating mill are analyzed in this paper.

分析了振动磨筒体内研磨介质的运动状态及粉磨机理，在此基础上，从能量观点出发，对振动磨整机的功率消耗进行了研究，并提出了计算振动磨机功率的理论公式。

As the density of Al and Cu was quite difference,it was apt to delaminate and restrain the process of alloy by wet milling.The case was improved when dry milling,though it would be some reunite with the time of ball-milling prolonging.(2)The best technique parameters of high energy ball milling to prepare metastable powders of Cu-Al alloy were;the addition of Al powders was 1% in quality,the powders of Cu-Al were completely alloyed after high energy ball milling for 20 h.

1提出采用高能球磨制备Cu-Al合金粉的有效方法，认为由于Cu和Al的密度相差比较大，采用以液态酒精为过程控制剂的湿磨时，容易发生分层，抑制了合金化，采用干磨时，以硬脂酸为过程控制剂，虽然随球磨时间的延长会发生轻微的团聚，但能达到良好的合金化效果。

Effect of grinding aids on grinding efficiency of Portland cement,slag cement and pozzuolana cement was evualated by adopting indexes such as residue of sieve,specific surface area and size distribution.Some references were provided for the selection of grinding aids by comparision test and results analysis.

选取了立窑和回转窑2种熟料，在同一试验条件下掺入不同种类及掺量混合材磨制成若干个试样，并采用筛余、比表面积及粒度分布等指标来评价助磨剂对普通硅酸盐水泥、矿渣水泥和火山灰水泥粉磨效率的影响，并进行了对比研究，通过作用效果的分析，为助磨剂的选用提供了参考依据。

A new type cement commonly apply closed-circuit circulatory system, that cement production not only rely on closed-circuit grinding system as well as the election system to elect the cement powder, but also the dust collection system to close down.

新型水泥制备普遍采用闭路循环系统，闭路水泥生产不仅要靠粉磨系统把水泥磨出来，靠选粉系统把水泥选出来，还要靠收尘系统把水泥收下来。

The main reasons of such explosions are that the velocity of primary air is too low when turn on and off the pulverizing system and the level of the coal in ball mill is too high.

通过分析，启停制粉系统时一次风速过低及磨煤机料位控制过高是造成爆炸的主要原因，为此提出制粉系统运行控制要点，及增加磨煤机火灾保护逻辑，效果明显。

Combined grinding of clinkers obtained from different types of kilns was studied with fuzzy sub-cluster theory. Clustering degree was proposed and used to represent the clustering ability of particles.

提出了用模糊群子理论的观点来看待两种熟料的混合粉磨过程，可采用群聚度来表征粉磨过程中粉体颗粒的聚集能力。

It is shown that combined grinding is very effective for clinkers with quite different clustering degrees. However, in the case of clinkers with similar clustering degrees, combined grinding is not recommended

研究表明：对于群聚度相差较大的立窑熟料与NSP窑熟料，宜采用混合粉磨方式；而群聚度相差不大的立窑熟料与NSP窑熟料，混合粉磨的效果不理想。

The vertical mill combines the functions of milling, selecting milled ore and stoving.

立式磨集粉磨、粉选、烘干功能于一体。

Meanwhile, it also analyzes the feature and development of semi-finish grinding and finish grinding by roller press.

同时进行了辊压机半终粉磨和终粉磨系统的特点和发展分析。

It also analyzes the feature and development of semi-finish grinding and finish grinding by roller press.

同时进行了辊压机半终粉磨和终粉磨系统的特点和发展分析。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
