辊式破碎机辊皮磨损的5大主要因素!
网址:http://www.dhfjx.cn    发布时间:2019-06-17
对辊式破碎机适用于在水泥、化工、电力、矿山、冶金、建材、耐火材料、煤矿等行业脆性块状物料的粗、中级破碎。对辊破碎机辊皮的磨损程决定着生产能力的多少,只有在辊皮好的状态下才可以使产量保证大,同时成品粒度保证好。那么有哪些因素会影响对辊破碎机辊皮的磨损呢?下面我们一起来看一下。
Roller crusher is suitable for crushing brittle bulk materials in cement, chemical industry, power, mining, metallurgy, building materials, refractories, coal mines and other industries. The wear process of the roll skin of the roll crusher determines the production capacity. Only under the best condition of the roll skin can the output be guaranteed to the maximum and the particle size of the finished product be guaranteed to the best. So what factors will affect the wear of roll crusher roll? Let's take a look at it.
辊皮磨损的主要因素
Main Factors of Roller Skin Wear
1、待处理矿石的硬度。如果物料硬度抗压强度大于 300MPa,则物料难以破碎,并且容易磨损辊皮。
1. Hardness of ore to be treated. If the hardness and compressive strength of the material is greater than 300 MPa, the material is difficult to break and easy to wear the roll.
2、辊皮材料的强度。一般采用耐磨性好的高锰钢或特殊碳素钢(铬钢、铬锰钢等)制作,可提高辊皮的耐磨性。
2. Strength of roll material. Generally, high manganese steel with good wear resistance or special carbon steel (chromium steel, chromium manganese steel, etc.) are used to improve the wear resistance of roll covers.
3、辊子的表面形状和规格尺寸以及操作条件。如果辊子表面不平滑,规格尺寸不符合要求,或者操作不当,都会造成辊皮磨损。
3. Surface shape and dimension of rollers and operating conditions. If the surface of the roll is not smooth, the specifications and sizes do not meet the requirements, or the operation is improper, it will cause roll skin wear.

4、给料方式和给料粒度。给料时分布不均,辊皮不但很快磨损,而且辊子表面会出现环状沟槽,从而破碎产品粒度不均匀。在破碎机的运转中,还要注意给给料粒度的大小,给料粒度过大,将产生剧烈的冲击,辊皮磨损严重,粗碎时尤为显着。
4. Feeding mode and feeding granularity. When feeding, the distribution is not uniform, the roll skin not only wears quickly, but also the surface of the roll will appear ring grooves, thus breaking the product particle size is not uniform. In the operation of crusher, attention should also be paid to the size of feeding granularity. Excessive feeding granularity will produce severe impact. Roller skin wear is serious, especially when crushing.
5、辊子的移动方式。当需要改变破碎比而移动辊子时,必须使辊子平行移动,防止辊子歪斜,导致辊皮迅速而不均匀的磨损。
5. Roller movement mode. When the crushing ratio needs to be changed to move the rollers, the rollers must be moved parallel to prevent the rollers from skewing, resulting in rapid and uneven wear and tear of the rollers.
