许多运营商面临着 situations where they have piles of unwanted materials that they are looking to reduce into concrete and asphalt aggregates without creating a high level of 罚款. Others are looking for ways to take similar piles and create a 分级良好的细粒产量. A discussion of which tool or tools are the right selection for any installation cannot be complete without a resolution of the actual 菠菜网最稳定正规平台_最全菠菜网大全ion 需求 and the associated revenue and profits per 菠菜网最稳定正规平台_最全菠菜网大全. Before we can assume any progress in the proper equipment selection, we must decide what needs to be produced and in what quantity.
生产要求可以用 many ways: tons per hour, tons per year or just tons. 生产要求 必须与某事相关才有意义. 一旦销售数量已经 determined, the 菠菜网最稳定正规平台_最全菠菜网大全ion 需求 can be established.
要小心分割你的生产 按小时数的要求. 这将导致平均产量， but may not coincide with the timing of requirement. 也有季节性的 issues where certain 菠菜网最稳定正规平台_最全菠菜网大全s will move at a faster or slower pace than the 全年平均值. While this may all seem elementary, this is a necessary step that will also help in determining the right machine for the market 需求.
有许多因素涉及到一个 收购战略. 考虑以下两个应用:
- 石灰岩: A tertiary application to handle 150 tph of 2” x ½” material to produce a quality ½” output material with a minimal amount of 4 mesh minus.
- 碎石: A tertiary application to handle 100 tph of 1” x 3/8” material to produce a graded and fractured 3/8” output material with a fair quantity of 4 mesh minus.
资本成本
A simple rule of thumb is this: When looking at sized machines for the 相同 application, a cone crusher will cost three times the price of the vertical shaft impactor. That is just for the machine and does not include any structure or auxiliary equipment. Used machines, rental and availability of the machinery will affect the final acquisition cost.
专门用于石灰石的应用, consider a 300-hp cone crusher or a medium-sized VSI with 300 hp. In round numbers, the VSI would cost $130,000, while the cone would come in at $350,000. With these numbers, it is not quite the 3:1 rule of thumb, but it comes close.
对于砾石应用, consider a 200-hp cone crusher at a price of $300,000美元，而较小的VSI价格为90美元,000. 同样，它接近3:1的比例.
穿成本
几乎每个人都会同意这一点 成本 of a cone crusher will be 少 than the VSI. 问题是，有多少 少? This is where it truly becomes application and site specific. 这也是 a great reason to have your material tested before making your final crusher 选择.
在理想的世界里, we would bring in a cone crusher and a VSI and measure all of the parameters and 成本 before making the 选择, 但这并不总是可行的. It is then that we have to make some assumptions based on experience within the site and using information gathered from similar sites. Experience can be a great assistant when we start to estimate the wear 成本.
对于石灰石的应用，我们估计 a wear life of four months on a set of shoes within the VSI while estimating a 锥形衬套寿命为两年. 你的经历很可能会有所不同 from these numbers, but since they are actual numbers for a specific 应用程序，它们可以用于比较.
要安装的部件的成本 combined with the labor 成本 to install them totals wear 成本 of $0.01 /吨 对于圆锥体和$0.VSI为05/吨.
同样，这些成本是零件和劳动力 与十年间生产的吨相比. 这些成本不放任何 停机时间的钱.
相比之下，对于砾石的应用我们 estimated a wear life of two months on a set of rotor tips (in this more abrasive application, we would use an autogenous rotor rather than the open shoe table) while estimating four months on a set of cone liners. 在这种情况下， 圆锥体的计算值为0美元.0.99美元/吨，VSI为0美元.15 /吨.
维护成本
这些费用占了时间和 materials for the regular maintenance items like oil changes, fluid levels, 传动皮带检查及其他定期活动. 这不包括修理和磨损 成本. Assuming 2,000-hour 年, the 成本 were estimated for five and 10 使用预见性软件的年限. 圆锥破碎机预保养 成本$0.5年和10年. 与此同时，VSI指数显示出上涨 维护成本为0美元.0026/吨，5年和10年.
维修费用
这个区域包括所有的维修费用 与每个破碎机相关联. 这也是一个可以大有作为的领域 可变性. Type of application, severity of duty and general operating conditions are just a few of the factors that are hard to program into any 预测软件. The software uses an estimated life expectancy of the 每台机器的组成. 这是人类的平均寿命 组件.
还包括劳动移除和 install the parts, plus any machining those parts will require. 如果有的话 重建能力也被考虑在内.
这种类型的另一个重要变量 software is the number of hours the equipment is to be run. 如果我们结束工作 right before a significant repair event (such as a bearing or bushing replacement), the cost per ton will be significantly 少 than if we end the 就在重大维修事件发生几小时后.
虽然没有足够的数据来证明 exact cost differences between the two application examples we are using, the key is that the data is being analyzed the 相同 for the cone and the VSI. It will allow us to predict the basic differences in repair 成本 over five- and 圆锥相对于VSI的10年周期. 个人申请将 需要进一步分析.
费用估计为1万英镑 20,000 hours, again using the 预测软件. 对于圆锥破碎机， 修理费为0美元.前五年每吨6美元，前五年每吨0美元.09/吨，前10个 年. 同时，VSI报告的维修成本为0美元.第一次是053/吨 5年零美元.前10年为078/吨. 还要记住 软件不包括停机时间的成本. 所以，虽然可能会有更多 instances of repair for the VSI over the cone crusher, the cost associated with 每个事件都不那么重要.
在您继续的过程中请记住这一点 thought process of how we decide the right tool for each application. 开始 with the best sales forecast and revenue dollars available to you. 调查 各种选择. 测试和验证你得出的任何结论. 利用 experience that is available within your company, as well as external sources. Challenge numbers and claims that seem too good to be true.
数字会根据 材料、应用和责任. 然而，使用的过程将是 相同. Many times, a possible solution is discounted too quickly without a 对事实和数字的简单调查.
