Roll Crushers
Roll Crushers are designed to handle the primary, 易碎物料(如煤)的二级和三级破碎, salt, clay, bauxite, 石灰石和其他具有类似特征的矿物在开采中, power generation and numerous other industries.
Applications
辊式破碎机是矿山工业中应用最广泛的破碎机之一，具有许多优点, such as high capacity, low headroom, low horsepower, the ability to handle wet, 粘性饲料和产生最小的罚款，同时生产立方体菠菜网最稳定正规平台_最全菠菜网大全.
简化的设计使这些装置具有优异的可靠性，并且需要很少的维护. 辊式破碎机设计有内置的颠簸救济，允许通过不可破碎的材料，同时继续操作并返回到初始菠菜网最稳定正规平台_最全菠菜网大全设置.
Roll Crushers have long been used in a variety of applications, including ROM feeds, coal, trona, salt, 玻璃和其他易碎矿物在采矿和回收工业.
How Roll Crushers Work
Whether the application requires a single-stage or two-stage crusher, 进行粉碎所需的力仍然是相同的:一个组合的冲击, shear and compression. 当物料进入破碎机并受到旋转辊的冲击时，就产生了冲击力. 当物料在破碎板和/或破碎辊之间被拉时，会产生剪切力和压缩力.
Depending on the feed size, 物料被送入破碎室，遇到一个或一对旋转的滚筒. 如果需要两级减速，则可以使用三辊或四辊配置. In this scenario, 破碎机的顶部阶段通过粉碎辊和破碎板之间或一对辊之间的物料来进行初级还原. 然后将材料直接送入两个底部辊子之间进行额外的加工.
If a single-stage reduction is required, then depending on the feed-to-product-size ratio of reduction, either a Single or Double Roll Crusher can be selected. Regardless of the crusher type selected, 辊式破碎机允许物料沿自然发生的解理线断裂, which helps with minimizing fines generation.
Why McLanahan Roll Crushers
Since patenting the first Single Roll Crusher in 1894, 麦克菠菜网最稳定正规平台_最全菠菜网大全已成为业内设计和制造单级和两级辊式破碎机的专家和领导者. 每个应用程序的选择过程都基于广泛的设备知识和丰富的测试数据，这些数据是在我们的研究实验室或通过现场测试开发的.
麦克菠菜网最稳定正规平台_最全菠菜网大全提供皮带驱动的辊破碎机在四种设计:单辊, Double Roll, Triple Roll and Quad Roll Crushers, 以低成本运营，并通过产生最小的罚款来最大化产量，从而提供可观的投资回报. The rugged design, 其中包括一个制造的钢基础框架内衬可更换的耐磨钢衬垫, 经得起最苛刻的矿物加工应用，同时提供安全和简单的操作, 包括一个自动行走救济系统，允许不可破碎的物体通过，而破碎机仍在运行中. These crushers are also versatile, 允许调整轧辊速度和间隙设置，以满足大多数应用要求.
Frequently Asked Questions About Roll Crushers
Ask An ExpertThe main factors to consider are the feed size and desired product size. Once this information is known and based on the ratio of reduction, the appropriate crusher selection can be made.
Yes, it will. When a wet, sticky feed is fed to a two-stage crusher, 你冒着在顶部和底部阶段之间堵塞破碎机的风险. If a wet, 粘性饲料是预期的，减少比例需要两个阶段的破碎, it is recommended that two separate single stages be used.
Impact Crushers, DDC-Sizers, and Hammermills are all crushing options you can consider. 就像所有的破碎机类型一样，每种风格都有自己的优点/缺点.
一个好的经验法则是:单辊破碎机有一个6:1的减少比例, Double Roll Crushers have a 4:1, 三辊破碎机有6:1在上阶段和4:1在下阶段, and Quad Roll Crushers have a 4:1 on both the top and bottom stage.
Single Roll Crushers
Single Roll Crushers 通常用作初级破碎机，提供高达6:1的破碎比. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines. Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.
Double Roll Crushers
Double Roll Crushers provide a 4:1 reduction ratio. 它们通常用作二级或三级破碎机，用于诸如带垃圾的ROM煤等材料, limestone, gypsum, trona, shale, bauxite, oil shale, clean coal, coke, salt, quicklime, burnt lime, glass, kaolin, brick, shale and wet, sticky feeds. 每台机器都是定制的，根据应用要求选择滚动元件和齿形，以最小的罚款生产立方体菠菜网最稳定正规平台_最全菠菜网大全.
Triple Roll Crushers
Triple Roll Crushers 对于想要一次完成两阶段还原的生产者来说是否理想. 它们可用于煤、盐、焦炭、玻璃和天然气等行业. 三辊破碎机将单辊破碎机与双辊破碎机结合在一起，形成一台破碎机，能够在初级阶段实现6:1的还原比，在二级阶段实现4:1的还原比，同时在高容量下生产隔间菠菜网最稳定正规平台_最全菠菜网大全.
Quad Roll Crushers
Quad Roll Crushers are ideal for producers, including those with preparation plants, who want to accomplish two stages of reduction in one pass. 它们可用于煤、盐、石灰、焦炭和钾肥等业务. 四辊破碎机能够达到4:1的还原比，然后再将破碎的物料送入二级阶段，再进行4:1的还原，以制造最终菠菜网最稳定正规平台_最全菠菜网大全.
