ca888亚洲城分析型煤中的破碎机特点


发布时间:2018-07-18 发布人:亚洲城ca88唯一官网

ca888亚洲城认为,型煤生产一般要求物料粒度在≤3mm,能满足该性能的破碎机很多,破碎机又各有特点,究竟该选择什么样的破碎机用在自己的型煤生产中需要综合考虑,不能盲目的说哪一种破碎机好,因为工况不同、型煤用途不同就需要不同的破碎机来完成,例如破碎无烟煤的破碎机和破碎兰炭粉的破碎机就不同,生产煤棒和煤球对物料粒度要求不同破碎机也不一样,生产的煤球用于工业锅炉还是民用取暖也会对破碎机有不同的要求,所以下文北京鑫众威矿ca888亚洲城会重点先容型煤生产中常用的几种破碎机的性能和特点,以方便型煤企业在选择破碎机的时候作为参考。
Type crusher manufacturers think, coal production general requirements material particle size in 3 mm or less, can satisfy the performance of the crusher, crusher and have their own characteristics, how to choose what kind of crusher is used in your model should be considered in coal production, cannot blind say which kind of crusher is good, because the working condition of different type, coal use will require a different crusher to complete, such as breakage of anthracite coal crusher and broken carbon powder of the crusher is different, the production of coal rods and coal requirements for material particle size and different crusher is different also, the production of the coal used in industrial and civil heating boiler also has different requirements to the crusher, So below Beijing xin zhong wei mine coal crusher manufacturer will focus on performance and characteristics of the commonly used several kinds of crusher, type for coal enterprise in choosing a crusher for reference.

1、双级破碎机
1. Two-stage crusher

双级破碎机主要是针对要求出料粒度较细的场合,在型煤生产中ca888亚洲城认为双级破碎机可以替代鼠笼破碎机,其结构上类似两台反击锤破碎机的组合,物料在进入第一级破碎机后经过初级破碎,在获得初级破碎机的动能的情况下进入二级破碎,从而达到细碎的要求,生产能力相对于同型号的单机锤破要低,堵料的几率要比同型号的锤破要高,出料粒度比同型号的锤破要细很多。
Two-stage crusher is mainly aimed at for discharging a finer granularity of occasions, coal type crusher manufacturers think that the two-stage crusher can replace squirrel-cage crusher, its structure is similar to the combination of the two hammer crusher, material into the crusher is the first step on the primary crushing, after enter the kinetic energy of the primary crusher secondary crushing, so as to achieve finely requirement, production capacity compared to the same single hammer broken, lower chance of plugging material to be higher than the same hammer broken, discharging granularity than the same hammer broken thin a lot.

ca888亚洲城指出这种破碎机的特点是:破碎比大,检修方便简单;缺点是:能耗高。目前这种破碎机在煤球生产中应用较多。
The crusher manufacturer pointed out that the characteristics of this kind of crusher are: large crushing ratio, easy maintenance; Disadvantages: high energy consumption. At present, this kind of crusher is widely used in the production of coal ball.

2、立式破碎机
2. Vertical crusher

立式破碎机是指传动轴是垂直的,相对于以上几种水平轴破碎机来说的,以上几种破碎机也可以统称为卧式破碎机。
Vertical crusher refers to the vertical shaft is vertical, compared with the above several horizontal axis crushers, the above crushers can also be collectively referred to as horizontal crushers.

立式破碎机一般是在一个圆形的破碎腔内的立轴上装有多层锤头,物料从上部入料口进入破碎腔中,通过自由落体到达第一层锤头,高速旋转的锤头会迅速将到达的物料通过离心力甩至桶壁的衬板上,物料遇到衬板会向桶中心反弹,同时下落至二层锤头,如此多次破碎后经破碎机的正下方排除,从而达到细碎的要求。因为型煤生产多为粉煤细碎,而且大多物料都含一定的水分,所以在破碎的过程中物料的反弹力较小,特别是筒体上壁在黏上部分碎煤后几乎使物料丧失了反弹力,所以容易造成堵料,破碎效果差,目前型煤生产用户较少。
Vertical crusher is usually in a circular multilayer hammer head mounted on the vertical crushing cavity, the material from the upper into the into the cavity broken through free-fall hammer head reached the first floor, the high-speed rotating hammer head quickly to jilt to barrel wall materials will arrive by centrifugal force on the lining of the material plate to the barrel center backlashes, falling to hammer on the second floor at the same time, after so many broken out just below the crusher, so as to achieve finely. Type for coal production is pulverized coal more finely, and most of the material containing certain moisture, so in the process of crushing material of rebound is small, especially on the cylinder wall on the sticky part after crushed coal materials almost lost the rebound, so easy to cause plugging material, crushing effect is poor, now the user type coal production is less.

ca888亚洲城指出这种破碎机的特点是:检修方便简单,能耗低,破碎比小,适用于干煤破碎。目前这种破碎机在煤型煤生产中应用较少。
The crusher manufacturer pointed out that the characteristics of this kind of crusher are: easy maintenance, low energy consumption, small crushing ratio, suitable for dry coal crushing. At present, this kind of crusher is seldom used in coal - type coal production.

最后北京鑫众威矿ca888亚洲城提箱各位,型煤生产过程中的破碎机选择要根据自身的工况来选择,不能一味的推崇或者否定某种破碎机,每种设备都有自身的特点,在选择破碎机的过程中也可以结合生产情况选择两种类型破碎机组合生产;型煤生产中不建议选择有筛底的破碎机,因为一旦煤湿造成产量降低很容易堵料,清理起来相当麻烦。
Finally Beijing xin zhong wei suitcase you ore crusher manufacturer, type in the production process of coal crusher choice to choose according to own condition, cannot blindly advocate or deny a crusher, each device has its own characteristics, in the process of selecting the crusher can also be combined with production situation to choose two types combination crusher production; It is not recommended to choose the crusher with sieve bottom in the production of type ii coal, because once the coal is wet, it is easy to block the material and it is quite troublesome to clean it up.
