The close-grip bench press targets the pecs, front delts, and triceps. Unlike a traditional barbell bench press, close grip focuses more on the delts and triceps. With your hands closer on the bar, you have to keep your elbows tight to the body.Keeping your elbows tight will put a big stretch on the triceps and promote tricep growth.

Impact Crushers. An impact crusher (also called a hammer crusher) is quite versatile. It can be used as a primary, secondary, or tertiary crusher. Impact plates and beaters – or hammers – are used to break down the material. The material is fed through the upper part of the crusher then hit by hammers.
