破碎机有哪些分类?具体都是用来破碎什么的?


发布时间:2018-06-25 发布人:亚洲城ca88唯一官网

破碎机按照大类可分为医用破碎机和矿业破碎机。矿业破碎机原理上适应于海量矿山硬岩破碎,其典型花岗岩出料粒度≤40mm占90%,该机能处理边长100~500毫米以下物料,其抗压强度最高可达350兆帕,具有破碎比大,破碎后物料呈立方体颗粒等优点。矿业破碎机械是指排料中粒度大于三毫米的含量占总排料量50%以上的粉碎机械。
分类
破碎机按照大类可分为医用破碎机和矿业破碎机。其中医用破碎机主要用于结石的破碎,一般采用共振等方式将结石破碎,避免手术带来的各种风险。
根据破碎的原理,目前常用破碎机械有鄂式破碎机、反击式破碎机、锤式破碎机、冲击式破碎机、辊式破碎机、复合式破碎机等。
破碎目的意义
1、目的:破碎机广泛运用于矿山、冶炼、建材、公路、铁路、水利和化学工业等众多部门。每年都有大量的原料和再利用的废料都需要用破碎机进行加工处理。如在选矿厂,为使矿石中的有用矿物达到单体分离,就需要用破碎机将原矿破碎到磨矿工艺所要求的粒度。需要用破碎机械将原料破碎到下一步作业要求的粒度。在炼焦厂、烧结厂、陶瓷厂、玻璃工业、粉末冶金等部门,须用破碎机械将原料破碎到下一步作业要求的粒度。
2、意义:在化工、电力部门,破碎粉磨机械将原料破碎,粉磨,增加了物料的表面积,为缩短物料的化学反应的时间创造有利条件。随着工业的迅速发展和资源的迅速减小,各部门生产中废料的再利用是很重要的,这些废料的再加工处理需用破碎机械进行破碎。

The crusher can be divided into medical crusher and mining crusher according to large categories. The mining crusher is adapted to the crushing of hard rock in mass mine. Its typical granitic granularity less than 40mm is less than 90%. This machine can handle the material under 100~500 mm. The compressive strength is up to 350 MPa, the crushing ratio is large, and the material is cube particle after crushing. Mining crushing machinery refers to the crushing machinery with a particle size greater than three millimeters in the row, which accounts for more than 50% of the total discharge volume.
Classification
The crusher can be divided into medical crusher and mining crusher according to large categories. The medical crusher is mainly used for crushing stones. Generally, the stones are broken by resonance and other methods, so as to avoid all kinds of risks brought by surgery.
According to the principle of breakage, the commonly used crushing machines are Hubei crusher, counterattack crusher, hammer crusher, impact crusher, roller crusher, compound crusher and so on.
The meaning of breakage
1. Purpose: crusher is widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries and many other departments. Every year, a large number of raw materials and reused waste materials need to be processed by crushers. For example, in the ore dressing plant, in order to separate the useful minerals from the ores, it is necessary to use the crusher to break the original ore to the size required by the grinding process. Crushing machinery is needed to break the raw material to the next step. In the coking plant, sintering plant, ceramic factory, glass industry, powder metallurgy and other departments, crushing machinery must be used to crush the raw materials to the next step.
2, significance: in the chemical and electric departments, crushing and grinding machinery breaks raw materials and grinding, increases the surface area of the material, and creates favorable conditions for reducing the time of the chemical reaction of the material. With the rapid development of industry and the rapid decrease of resources, it is very important to reuse the waste materials in various departments. The reprocessing of these wastes should be broken by crushing machinery.
