Impact Crusher

Kefid Impact Crusher is the most  mature stone crusher with more than 20 years manufacturing  experience, it has won worldwide reputation due to its economical price, high capacity, high reduction, fine grain shape, easy adjustment and easy maintenance. Impact crusher are usually used to processing ore stone by impacting. Kefid impact crusher have three types: PF Impact Crusher, Primary Impact Crusher, Hydraulic Impact Crusher. They are widely used in building materials, cement processing , mining and chemical industries, crushing soft material, medium hardness minerals. Maximum Feed size range (the maximum anti-crushing compressive strength 300Mpa, humidity should be less than 8-10%) should be no more than 700MM.

PF Impact Crusher

PF Series Impact Crusher uses the latest manufacturing technology, unique structural design.  It offers larger crushing ratio and more fully utilizes the high-speed impact energy of the rotor, which is the best choice in stone and gravel crushing line. However, as crusher boards are easy to wear, there is a limitation to crush hard materials, PF series impact crusher is usually used for coarse and fine crushing of medium-hardness materials. The ideal feed size of PF impact crusher is 100-500mm, the maximum sizes shall not exceed the specification. Users can adjust final particle sizes via the space between the hammer head and impacting plate.

Primary Impact Crusher

Primary impact crusher is KEFID’s new product absorbing international latest technology. PFP series primary impact crusher offers excellent quality and efficiency. Rotor, as the heart of the primary impact crusher, makes great contribution when working, so it needs strict quality control. We developed stronger rotor to produce heavier moving inertia. Hard wear resistant material and the best cavity design make sure the excellent performance of the crusher, which is suitable to crush various medium-hard and soft materials to coarse sizes.
