Bergkrossmaterial som ballast i Betong

Bergkrossmaterial som ballast i Betong Björn Lagerblad & Mikael Westerholm CBI Betonginstitutet Hans-Erik Gram Cementa AB ballast Polerad yta 15 cm Ballast ballast Tunnslip 5 mm cement SEM 50 µm 1 Orientering Bakgrunden till detta arbete är Svenska regeringens naturgrusmål som av miljöskäl vill minska användningen av naturgrus. En av de största förbrukarna av är tillverkning av betong där finmaterialet ( mm) huvudsakligen kommer från naturgrus. Om naturgrusmålet skall uppnås måste stora delar av denna sand ersättas med krossprodukter. Krossprodukterna skiljer från naturgrus främst genom att partiklarna är mera kantiga och har en råare yta. Detta beror på att naturgrus även om det ursprungligen kommer från berg har bearbetats och nötts av i naturen, framför allt under istiden. Dessutom har många svagare material under tidens gång brutits ner. Då krossballast har andra egenskaper än naturgrus måste man lära sig förstå dess egenskaper och anpassa betongproportioneringen till dessa. Ett av problemen är att med nuvarande proportioneringsmetodik så kommer övergången från natur- till krossballast att innebära att betong för att uppnå en er

    • A vertical shaft impact (VSI) crusher, also known as a sand-making machine, can efficiently turn small rocks or other materials into sand. By using a high-speed rotor with several carbide-inserted tips, a VSI crusher can accelerate the rocks and throw them against a crushing chamber’s stationary walls, thus breaking the rocks. It is widely used in the construction, mining, quarrying, and recycling industries. In this article, we will explore what a VSI crusher is and its components. Scroll down to discover the details.

    What is a VSI crusher?

    A vertical shaft impact (VSI) crusher is a crucial tool for various crushing applications. Its primary purpose is to produce products used in the construction industry, such as aggregates. Besides, in the field of recycling building materials such as asphalt and concrete, VSIs are also of vital importance. In addition, another key application of VSI crushers is producing industrial sand, which is a component in the manufacturing of products like ceramics.

    Unlike a jaw crusher or a cone crusher, a VSI crusher is capable of producing well-shaped and evenly graded aggregates, making it suitable for applications where consistent aggregate

    Vertical Shaft Impact Crushers:A Comprehensive Guide

    Vertical Shaft Impact Crushers, commonly referred to as VSI Crushers or småsten Making Machines, are the result of years of expertise in the mining machinery industry. These crushers are highperformance, lowconsumption devices that stand out among various ore crushing redskap. They play an irreplaceable role in the fine crushing of various ores and are currently the most effective, practical, and reliable stone crushing machines available. This article will provide an indepth look into the applications, working principles, and outstanding features of VSI Crushers.

     

    Vertical Shaft Impact Crushers Applications

     

    VSI Crushers are versatile machines widely used in multiple industries including ore processing, cement production, refractory materials, bauxite clinker, carborundum, glass raw materials, artificial building småsten, aggregate, and various metallurgical slag processing. They are particularly efficient in the crushing and shaping of hard and extremely hard materials such as silicon carbide, carborundum, sintered bauxite, beautiful småsten, etc., offering higher output efficiency compared to other types of c
