斯奈德(Snyder)法基本上是一种应用空气、气体或者蒸气压力于压力室中进行破碎物料的方法,物料被压力突然消失时所产生的应力所破碎,并使物料沿管道排入收集室。本文的首要目的是介绍该法破碎不同物料的某些应用。在所选择的例举中均进行了一般碎矿法的平行试验。例举说明了下一步选矿的对比详细情况,并且指出了两者最终精矿品位和回收率的差别。该差别表明,在各种情况下,采用斯奈德法破碎物料均具有良好的选矿效果,该效果被认为是由于在较粗粒级时矿物的解离度得到了改善,在某些例举中,显微镜观察结果也证实了此种情况。关于该法的发展历史、最初级工业设备的改进以及工业方面的需用情况进行了一般介绍。概述了引起物料破碎的各因素,这些因素已纳入进一步的研究计划中。介绍了美国康涅狄格州的布鲁克菲耳德(Brookfield)的试验设备、步骤以及正规的试验研究工作,目前最大的设备在开路条件下其试验处理物料的能力接近30吨/小时,所要增加的更大的试验设备正处于设计阶段或在考虑之中。
The Snyder method is basically a method of crushing material in a pressure chamber using air, gas or vapor pressure. The material is crushed by the stress generated when the pressure suddenly disappears and the material is discharged along the pipeline to be collected room. The primary purpose of this article is to introduce some of the applications of this method to crush different materials. In the chosen examples, parallel tests of the general crushing method were conducted. An example is given to illustrate the details of the next step beneficiation, and the difference between the final concentrate grade and the recovery rate of both. This difference indicates that in all cases the Snyder method of crushing the material has good beneficiation results, which is believed to be due to the improved dissociation of the minerals at the coarser levels and in some cases In the microscope observation results also confirmed this situation. A general introduction was given on the history of the law, the improvement of the most advanced industrial equipment, and the industrial needs. An overview of the factors that cause material breakage has been incorporated into further research programs. Introduced the test equipment, procedures and formal experimental research work at Brookfield, Connecticut, USA. At present, the largest equipment under test has the capacity of handling test materials close to 30 tons / hour under open conditions, and needs to be increased more The test equipment is in the design stage or under consideration.
