Impact and extrusion contrast: 1, crushing ratio. Impact crusher crushing ratio may reach 50 or more, and squeeze crusher difficult to over 20. More suitable for single-stage crushing of occasions. 2, product particles. Flakiness percentage content of the impact crusher product may be less than 10%, while the percentage of flakiness content extrusion crusher will be higher than 15%. So miniature hammer crusher, in case of need cubic grains, usually impact crusher as the final breaking equipment to produce concrete aggregate. 3, due to the impact crusher is the use of the principle of broken material impact, wear very fast in use. This defect, in a fairly long period of time, limit the scope of the impact crusher. Can only be used for crushing medium-hard materials. Latest gravel aggregate production equipment VI vertical impact crusher in the national market has achieved outstanding market share, product performance more perfect, far to the user's shores. This product is widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and various metallurgical slag and other industries. Note: China has called for the vertical impact crusher, China Building Material Industry Association China Association of gravel authorize led the development of industry standards Sand also scheduled for the vertical impact crusher. Vertical impact crusher is a new type of device it works US Department Pamanleti vertical impact crusher out, there are a variety of products, product names differ in Europe, in our country often referred to as vertical impact crusher. Such devices have been used for 30 years had more than mine medium hard ore crushing. 1988 German Martin Stan Cole off the first time the company DAVID vertical impact crusher submitted to cover mosaic cement used in combination with the existing cement mill better. VI vertical impact crusher aggregate production process - can be designed dedicated high speed (high grade) highway, railway, hydropower industry, the production of new sand and gravel aggregate crushing and screening production process; the crushing and screening equipment according to the installation divided into fixed mine hammer crusher, semi-mobile (sled) and three mobile crusher hammer crusher station, its production capacity 30-500 tons / hour, product size and gradation according to user needs The set is usually 0 ~ 40mm; gravel aggregate production of the finished product with the management, good grain shape, flakiness particle content can be controlled within 5%.
