易磨性

与 易磨性 相关的网络例句 [注:此内容来源于网络,仅供参考]

In addition, there is delamination removal at weak interface due to decarburization.

普通涂层的磨损机制为微切削;纳米涂层在轻载(10 N)下,以塑性变形为主要磨损机制,随载荷增加至30 N,纳米WC粒子不能起到阻抗陶瓷球对磨副的磨削作用,而是随粘结相一起被去除,同时由于纳米涂层脱碳导致的层间结合薄弱,在滑动磨损中易发生成片剥落,耐磨性大幅下降。

This is the result of different grinding properties.

这是由于熟料的中各矿物的易磨性不同造成的。

Crystalline transformation of finely ground sand stone with and without the addition of mineralizer of A,B,CaF2 and CaSO4+CaF2 heated at certain temperature was determined by means of DTA and XRD.The test of burnability of raw meal was also conducted in this work.

将砂岩细磨或在砂岩中分别掺入矿化剂A、B、CaF2、CaSO4+CaF2,然后在适宜温度下煅烧,用DTA和XRD测试了砂岩的晶型转变,并进行了生料易烧性试验。

Process of flotation of acture ore is the following: firstly, adding Na_2CO_3, ZnSO_4, CSU-1 to the pulp while grinding, and thus in this condition of low Eh, marmatite is inhibited; Secondly, adding CSU-1 to the pulp out of grinding machine, then amesonite and iron sulfur mineral can be flotated using diethyldithiocarbamate as collector; High quality lead and antimony concentrate can be got by adding CSU-1 and calcareousness; Lastly, marmatite is flotated by adding calcareousness, CuSO_4, xanthe, and D-250 to get zinc concentrate.

小型试验研究表明,首先在脱硫粗选作业只加入适量的Na_2CO_3、ZnSOO_4、和CSU-1至磨矿机,利用磨矿机的研磨和磨机中的低电位环境,使铁闪锌矿受到抑制,而最容易浮的脆硫锑铅矿和黄铁矿、磁黄铁矿等硫化矿物则依然具有可浮性;在磨机出来的矿浆中分别加入CSU-1进一步抑制易浮的铁闪锌矿,然后加入乙硫氮将脆硫锑铅矿和硫化铁矿快速浮净,加入石灰和CSU-1,浮选分离出高质量的铅锑精矿;接着添加石灰、CuSO_4、黄药及2~#油选别铁闪锌矿。

The grindability of cement clinker was better than ordinary Portland cement, for example, on the same condition it took the high alite content Portland cement clinker 4.5min to grind to a specific surface area of 320m2/kg, while the o...

同时这种水泥熟料的易磨性优于普通硅酸盐水泥熟料:在相同条件下,磨细到比表面积320m2/kg时,这种熟料需要4.5min,而普通硅酸盐水泥熟料则需要8.0min。同时对该熟料进行了岩相检验分析。

The sort and reason of grinding burn were analyzed. Based on the characteristic of the coned shape grinding wheel, the fac-tors of affecting the depth of the thermal damage layer were found.

锥面砂轮磨齿机工作时,由于工件受热和冷却、膨胀和收缩等不均匀性及磨削过程中各种变化因素的作用,极易产生磨削裂纹和烧伤。

This trial test prows that when specific surface remains constant, the output of mill was l0%~15% increased per machine-hour, power consumption reduced 3 kWh/t; when admixture adding rate increased 6%, strength of test samples in each age is equal to that of samples without compound grinding aids added; the initial setting and final setting time are shortened slightly; the workability and fluidity of cement and the grindability of materials are improved remarkably.

结果表明,在比表面积保持不变时,台时产量可提高10%~15%,粉磨电耗成本可下降约3kWh/t;混合材掺量增加6%后,试样各龄期强度与不加复合助磨剂的水泥样强度相当;水泥的初、终凝时间均有所缩短;水泥的和易性、流动性及物料的易磨性能等方面均得到较大的改善。
