一、仪器简介：
狄法尔磨耗试验机适用于絮状矿物纤维的抗磨耗性能试验，同时也适用于欧标、法标等相关标准对石料集料的磨耗率试验，也就是抗摩擦和抗冲击试验。可以测量出石料的耐磨强度。对于一些石料，这种耐磨强度在干燥和含水的情况下是不同的。主要用于石料的磨耗率试验，也就是抗摩擦、抗冲击，为鉴定集料品质的指标。
1. Introduction
The Diffar abrasion tester is suitable for the abrasion resistance test of flocculent mineral fibers, as well as the abrasion rate test of the European standard, French standard and other related standards on the stone aggregate, that is, the anti-friction and impact resistance test. The wear resistance of the stone can be measured. For some stone materials, this abrasion strength is different in dry and hydrated conditions. It is mainly used for the abrasion rate test of stone, that is, anti-friction, anti-impact, as an index to identify aggregate quality.

二、主要结构：
狄法尔磨耗试验机有滚筒、密封盖、支架、变速箱、电机、控制器等部份所组成。整机结构简单操作方便，运行时间可调。
2. Main structure
The Diffar abrasion tester is composed of rollers, sealing covers, brackets, gearboxes, motors, and controllers. The whole structure is simple and easy to operate, and the running time is adjustable.

三、仪器特点：
它包括有四个一端封口的空心圆筒，对于粒度介于 4 至14 毫米之间的粒料，圆筒内直径为 200±1 毫米，有效长度为154±1 毫米。圆筒为不锈钢材质(Z 2 CN 18-10), 厚度不小于3 毫米。它们被安装在两条水平轴上。每个圆筒可以用于一个试验。圆筒内部不能存在任何由于焊接或固定方式引起的隆突不平。用8 毫米厚的平盖来封闭圆筒。通过平盖上的接缝来确保密封性。磨料由直径为 10±0.5 毫米的不锈钢圆形滚珠组成 Z 30 C 13。使钢珠通过两个间距为 9.5 毫米的平行棒，或者以10 个用过的滚珠为一组称量其质量，该质量不能够小于34 克，由此快速地检查滚珠的直径。一个电动机(大约1 千瓦)，它必须确保圆筒以100tr/min±5 tr/min 的速度匀速旋转。一个在试验结束时可以自动中断发动机运转。
Three, instrument characteristics
It includes four hollow cylinders sealed at one end. For pellets with a particle size between 4 and 14 mm, the inner diameter of the cylinder is 200 ± 1 mm and the effective length is 154 ± 1 mm. The cylinder is made of stainless steel (Z 2 CN 18-10), and the thickness is not less than 3 mm. They are mounted on two horizontal shafts. Each cylinder can be used for one test. There should not be any bulges caused by welding or fixing in the cylinder. Use an 8 mm thick flat cap to close the cylinder. Sealing is ensured by the seams on the flat cover. The abrasive consists of stainless steel round balls with a diameter of 10±0.5 mm Z 30 C 13. Pass the steel ball through two parallel rods with a spacing of 9.5 mm, or weigh the mass of 10 used balls as a group. The mass cannot be less than 34 grams, thereby quickly checking the diameter of the balls. An electric motor (approximately 1 kilowatt), which must ensure that the cylinder rotates at a constant speed of 100 tr/min ± 5 tr/min. One can automatically interrupt engine operation at the end of the test.
