中药超微粉碎机内速度差是怎么调节的?

1、恰当调理锤筛间隙:应用筛外表的摩擦力随物料与筛外表间隔不同而摩擦力不同的特性,经过调理锤筛间隙,增加锤片和物料的锤击速度差,从而进步效率.但是,在粉碎消费过程中,筛孔不同,原料不同,锤筛间隙需求经常调整;在粉碎机内,粉碎机的刚开端工作和工作一段时间后,粉碎机内腔的颗粒成分也会变化;在粉碎机部件中,锤容易磨损,锤片前端磨损后,锤筛间隙变化增加,产量就会降落,难以耐久
1. Appropriate adjustment of hammer-sieve clearance: Applying the different characteristics of friction force between material and screen surface, the efficiency is improved by adjusting hammer-sieve clearance, increasing hammer-sieve speed difference between material and hammer. However, in the process of crushing consumption, the need for hammer-sieve clearance is often adjusted because of the different sieve holes and raw materials; in the crusher, the initial work and working section of the crusher are often adjusted. After time, the particle composition in the inner chamber of the crusher will also change; in the parts of the crusher, the hammer is easy to wear, and after the front end of the hammer is worn, the gap between the hammer and the screen will increase, and the output will fall, which is difficult to endure.
当然,为了某种粉碎机产量测试工作的需求,对某种原料,某种筛孔,肯定适宜的锤筛间隙和吸风,在不思索筛片和锤片运用寿命的状况下,能够在短时间内获得很高的粉碎效率的数据,但是,在饲料粉碎消费中,这种以操作人员的工作经历为条件呈现的各种特定的测定数据和粉碎机自身的技术含量是二回事,具有丰厚操作经历的人员及其劳动也需求很高的运用本钱.锤片磨损后,锤筛间隙增加,摩擦力减小,粉碎效率降落
Of course, in order to meet the demand of production test of a crusher, the suitable hammer-sieve clearance and suction for a certain raw material, a certain sieve hole can obtain high crushing efficiency data in a short time without considering the service life of the sieve and hammer. However, in the consumption of feed crushing, this kind of specific measurement data and data presented under the condition of the working experience of the operator are presented. The technical content of the crusher itself is different. People who have rich experience in operation and their labor also need high cost of application. After the wear of the hammer, the clearance between the hammer and the screen increases, the friction decreases, and the crushing efficiency decreases.
2、合理应用筛的背面毛刺:将筛冲孔发毛的一面放在里面,能够增加摩擦力,但用不多久,筛孔毛刺磨光后,效率没有了.耐久时间约30分钟到1个小时
2. Reasonable application of the back burr of the screen: Punching the hair side of the screen into the screen can increase friction, but it will not be long before the burr of the screen hole is polished, the efficiency will be lost. The durability time is about 30 minutes to 1 hour

3、增加吸风:在粉碎机系统加负压,吸紧附在筛内外表的物料,使物料在筛外表摩擦力增加,也能够增加锤片和物料的锤击速度差,但吸风增加也会增加锤、筛的磨损,效率不耐久.同时吸风的功耗也增加
3. Increase suction: add negative pressure to the crusher system and absorb the material attached to the inside and outside surface of the screen, so that the friction of the material on the outside of the screen increases, and it can also increase the hammer and material hammering speed difference, but the increase of suction will also increase the wear of the hammer and screen, and the efficiency is not durable. At the same time, the power consumption of suction will also increase.
4、在粉碎机内放置搓板:搓板有阻物料环的作用,但是作用有限,一是搓板的齿作用于锤的前端,摩擦面小,锤片磨损也有耐久问题;二是搓板挤占筛的包角,搓板面积过大筛就会减小,而筛面积过小产量就会减少
4. Place a rubbing board in the crusher: the rubbing board has the function of blocking material ring, but its function is limited. First, the teeth of the rubbing board act on the front end of the hammer, the friction surface is small, and the wear of the hammer is also durable. Second, the rubbing board occupies the wrap angle of the sieve, and the area of the rubbing board is too large and the output of the sieve area is too small.
5、采用鱼鳞筛技术:鱼鳞筛外表有许多小的突起,起到加强摩擦的作用,鱼鳞筛不占筛包角能够增加筛面积,比搓板有进步,但鱼鳞筛的小突起容易磨损,价钱较贵,推行很艰难,核算增加的产量和抵去筛的费用后,效益不明显
5. Adopting scale sieve technology: there are many small protrusions on the surface of scale sieve, which can strengthen friction. Scale sieve can increase the sieve area without occupying the wrap angle of the sieve, which is better than the washboard. However, the small protrusions of scale sieve are easy to wear and tear, the price is more expensive and the implementation is very difficult. After calculating the increased output and offsetting the cost of sieving, the benefit is not obvious.
6、采用薄锤片技术:薄锤片外形侧面窄(4毫米以下),其原理是不易搅起物料,不易产生物料跟锤片同速旋转的趋向.普通状况下,在同种型号构造的粉碎机采用薄锤片后,都能够在原有的根底上增加产量20%左右,薄锤片技术比拟有效,又很荫蔽,十分有利于对各种粉碎机产品的销售工作,特别是在粉碎机在测定产量时,产生了短期的对粉碎机消费商有利的状态,很容易将其他非有效技术特征的产品采购进来
6. Using thin hammer technology: thin hammer has narrow profile (below 4mm), its principle is that it is not easy to stir up materials, and it is not easy to produce the tendency of material rotating at the same speed with the hammer. Under normal conditions, after using thin hammer in the same type of crusher, the output can be increased by about 20% on the original base. The thin hammer technology is comparable effective and very shady, which is very conducive to various crusher products. Sales work, especially in the determination of production of crushers, produces a short-term favorable condition for crusher consumers, and it is easy to purchase other products with ineffective technical characteristics.
