1、砂石系统生产能力的确定、选定工作制度根据系统性质及供料、供水、供电、设备检修等条件确定。1、月工作天数：一般为25天。2、日工作班数：2班或3班作业。3、日工作小时：由日工作班数和各部位生产情况确定。4、毛料采运时间：根据要求的开采强度，采运设备的生产能力选定。5、半成品加工时间：要求超径石处理、予筛分、粗碎、中碎的时间致。3班作业为15 20小时；2班作业为11 14小时。6、成品筛洗时间：3班作业为20小时；2班作业为12 14小时。7、人工制砂时间：要求3班24小时作业,以求产品粒度的稳定。 二、系统生产能力的确定N日工作小时数；按工作制度选定。2、系统毛料处理能力:Pin = P/q
