The reduction ratio of a horizontal impact crusher is much higher than that of a jaw or cone crusher. The ® APP series is the larger of the two crushers and is used for primary stage crushing of larger feed sizes.

 — Follow the steps outlined in this article to achieve the best crushing efficiency for jaw, cone, gyratory and impact crushers and to ultimately increase profits and reduce fines production. By taking these steps, you're reducing the amount fines produced and adding dollars to your pocket.

 — A ttrition crushers – which use both impact and grinding to shear material. Jaw crushers, cone crushers, gyratory crushers and roll crushers all operate on the compression principle. Impact crushers utilise the impact principle, while hammermill crushers follow the principal of attrition. Compression crushers.

HIGH REDUCTION RATIO MPI crushers achieve a higher reduction with fewer crushing stages, lowering your capital costs and saving energy. The design of crushing chamber with double breaker plates ensures great reduction ratios and with the addition of a third plate, reduction ratio can even be improved. CUBICAL PRODUCT

® NP™ crushers' reliability. High capacity combined with high reduction ratio results in high performance crusher. In addition, whenever tertiary crushing stage can be avoided, the capital costs and need for energy drop notably. Durable wear parts and mechanical components reduce maintenance costs. Mechanical reliability, simplified

 — Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 per cent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.

The impact crusher (typically PE series) is widely used and of high production efficiency and good safety performance. The finished product is of cube shape and the tension force and crack is avoided. Compared with hammer crusher, the impact crusher is able to fully utilize the high-speed impact energy of entire rotor.

REVERSIBLE IMPACTORS. High Capacity Size Reduction of Solids by Mid-Air Impact. Applications. Features. Williams Reversible Impactors are among the most advanced of the secondary or tertiary crushers to achieve a high reduction ratio.

 — The reduction ratio for a jaw crusher is typically 6-to-1, although it can be as high as 8-to-1. Jaw crushers can process shot rock and gravel. They can work with a range of stone from softer rock, such as limestone, to harder granite or basalt. HORIZONTAL-SHAFT IMPACT CRUSHER.

As a kind of basic first rule you could say: Impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%).
