锤破和反击破碎机如何取舍?
网址:http://www.dhfjx.cn    发布时间:2021-07-08
加工不同硬度的岩石,配置的机器也不同,反击式破碎机和锤式破碎机都是利用高速冲击作用来破碎物料,而且反击破和锤式破不仅外形相似,还都有转子结构。所以,很多人认为反击破和锤破这两种破碎设备没什么区别,其实除了设备外观、构件的不同以外,反击式破碎机和锤式破碎机在破碎腔、易损件、出料调节、转子结构等方面都有着很大的差别。下面,我们就具体看看反击式破碎机和锤式破碎机有哪些不同吧。
Processing different hardness of rock, the configuration of the machine is also different, impact crusher and hammer crusher are using high-speed impact to crush materials, and impact crusher and hammer crusher are not only similar in shape, but also have rotor structure. Therefore, many people think that there is no difference between impact crusher and hammer crusher. In fact, in addition to the differences of equipment appearance and components, impact crusher and hammer crusher have great differences in crushing cavity, vulnerable parts, discharge adjustment, rotor structure, etc. Now, let's take a look at the differences between impact crusher and hammer crusher.
破碎腔不同
Different crushing chamber
反击破的破碎腔较大,进料口低矮且大,物料的破碎不仅靠锤头的冲击作用,还利用物料与反击板或物料与物料之间的反复冲击,受到的冲击破碎作用更加充分,从而更好地破碎大块物料。而锤破的破碎腔较小,结构密封性能好,解决了破碎空间的粉尘污染和机体漏灰等问题。
The crushing cavity of impact breaking is large, and the feeding port is low and large. The crushing of materials depends not only on the impact of hammer, but also on the repeated impact between materials and impact plate or between materials. The impact crushing effect is more sufficient, so as to better crush large materials. However, the crushing cavity is small and the sealing performance of the structure is good, which solves the problems of dust pollution in the crushing space and ash leakage of the body.

板锤/锤头作用方向不同
The action direction of plate hammer / hammer head is different
反击破的板锤是从下往上迎接物料进行破碎作业的,并且会把物料抛到上方的反击板上。锤式破碎机则是顺着物料落下的方向打击破碎的。反击破转子顺时针运转,板锤从下往上迎向物料;锤破转子逆时针运转,锤头顺着物料落下的方向打击
The plate hammer of impact breaking is to meet the materials from bottom to top for crushing operation, and will throw the materials onto the impact plate above. Hammer crusher is along the direction of falling materials to break. The counter breaking rotor runs clockwise, and the plate hammer faces the material from bottom to top; The hammer rotor runs counter clockwise, and the hammer head strikes in the direction of material falling
易损件磨损不同
Wear of vulnerable parts is different
板锤和锤头分别是反击破和锤破的主要易损件。反击式破碎机板锤的磨损主要出现在迎向物料的一面,板锤的金属利用率可达到45%-48%。而锤破的锤头因为呈悬垂状态,磨损发生在上、前、后和侧面,相对于板锤,锤头磨损更严重,金属利用率在35%左右。
Plate hammer and hammer head are the main vulnerable parts of impact and hammer respectively. The wear of plate hammer of impact crusher mainly appears on the side facing the material, and the metal utilization rate of plate hammer can reach 45% - 48%. Compared with the plate hammer, the wear of hammer head is more serious, and the metal utilization rate is about 35%.
出料调节方式不同
The discharge adjustment mode is different
反击式破碎机下部没有篦条筛,产品粒度的调节可以通过调整转子速度或转子直径、调整分料器开口大小、调节研磨腔的间隙的方法来控制。锤式破碎机则通过调节筛板缝隙的大小来控制产品粒度。因而,在处理含水量较大的物料时,反击式破碎机能够避免破碎湿物料时堵塞篦条的现象,更加有优势。
There is no grate screen at the bottom of impact crusher. The adjustment of product particle size can be controlled by adjusting the rotor speed or rotor diameter, adjusting the size of distributor opening and adjusting the gap of grinding chamber. The hammer crusher controls the particle size of the product by adjusting the gap size of the sieve plate. Therefore, when dealing with materials with high water content, the impact crusher can avoid blocking the grate when crushing wet materials, which has more advantages.
转子链接不同
The rotor links are different
反击式破碎机的板锤和转子是刚性链接的,即板锤固定地安装在转子上,破碎时能充分利用整个转子的惯性对物料进行冲击作用,不仅破碎物料,还具有很大的速度和动能。而锤式破碎机的锤头是单个对物料进行破碎的(锤头呈悬垂状态),具有的速度和动能都有限。
The plate hammer and rotor of impact crusher are rigidly linked, that is, the plate hammer is fixed on the rotor. When crushing, it can make full use of the inertia of the whole rotor to impact the material. It can not only crush the material, but also has great speed and kinetic energy. However, the hammer head of hammer crusher is used to crush the material individually (the hammer head is suspended), and its speed and kinetic energy are limited.
从以上对比我们可以看到,反击式破碎机在破碎大块物料、含水量相对较高的物料方面更有优势,而锤式破碎机更适合破碎粒度较小的物料。在实际生产中,您可以根据自己的生产情况选择适合的设备,保证生产效果。
From the above comparison, we can see that impact crusher has more advantages in crushing bulk materials and materials with relatively high water content, while hammer crusher is more suitable for crushing materials with smaller particle size. In actual production, you can choose suitable equipment according to your own production situation to ensure the production effect.
