Impact and extrusion contrast: 1, crushing ratio. Impact crusher crushing ratio may reach 50 or more hammer crusher, crusher and squeeze hard 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%. Thus, 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 miniature hammer crusher, 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. FL Series Vertical compound crusher is like our home and abroad crusher advanced technology, optimized design developed from the new crushing, coarse grinding products, it has a simple structure, large crushing ratio, low energy consumption, stable operation, operation and maintenance and convenient. The products are mainly used in cement raw material, clinker crushing hammer crusher manufacturers, cement plant transformation, cement production line ideal crushing equipment, but also for other medium hard ore crushing operations, such as soft iron ore, sandstone, gypsum, blast furnace slag, coal gangue, lump coal, metallurgical raw materials such as solvents. Hammer crusher manufacturers, Lei Machinery (certified), hammer crusher provided by Zhengzhou Machinery Co., Ltd. Lei. Zhengzhou Lei Machinery Co., Ltd. (www.hnzljx.net) (www.hnzljx.net) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs.
