对锤刀式湿煤破碎机的技术改造
|
摘要
对锤刀式湿煤破碎机的筛板、破碎部件、密封件、刮煤装置、机身等进行技术改造,可解决机器运行时有异响、机身晃动、煤样撒漏、破碎效率低、粉尘量大、机器易堵塞等问题。通过改造前后的制样精密度对比可知,改造锤刀式湿煤破碎机后可提高制样的准确度并解决煤样堵塞的问题,确保煤样顺利通过破碎筛分系统,可提升筛分效果和破碎效率并避免残留煤样互相污染。
The technological reformation on parts of knife type wet coal crushing machine such as sieve plate,crushing parts,seals,coal scraping device,machine body was done,the problems like different ringing during operation,machine body shaking,coal sample leakage,low crushing efficiency, large amount of dust, machine blockage could be solved. Through the comparison of sample preparation precision before and after reformation,after reformation of knife type wet coal crushing machine,the sample preparation accuracy could be improved,and the block of coal sample could be solved,therefore,the coal sample could get through the crushing and screening system smoothly,the screening effect and crushing effect could be improved,and the contamination of sample with each other could be avoided.
