National specification requirements, highway pavement, bridge building stone used in flat-elongated stone stone content can not exceed 15%. So to solve this problem, Yu-Hui jaw crusher  research experts. Crusher because of its rugged durability, easy maintenance, easy replacement of broken boards, etc. in the possession of a large gravel drive market share, but its output pin sheet in the broken stone stone content of more, which is also sectors such as roads and buildings was refused to use. Thus reducing the elongated stone content is imperative.

The company's production of broken stone crusher on a good crystal shape, elongated small advantages. Is to reduce duplication of broken stone elongated effective way, in the crushing process produces elongated stone is inevitable, the key is in the sheet discharge before the needle broken stone can not be repeated, if the stone has been repeated in the crushing chamber broken the more the number of elongated stone will be the first sheet from the needle or broken stone at a lower intensity, so that the needle can not be a flake of stone natural stone and has a pin sheet features a crystal-like stone.

Yu Hui, mechanical existing jaw crusher jaw and vertical dynamic angle of 25 °, as long as the moving jaw angle between the vertical to 35 ° -45 °, it can reduce the stone of the pin sheet content, produce a good crystal shape stone. If you want to test, just making an adjustable angle rack, the existing jaw crusher installed in the rack, and then moving the palate to adjust to various angles for stone crushing test. Activities of the jaw plate against the fixed jaw plate with crushed rub back and forth movement, then separated, and then close. When two separate jaw plate, material flew into the crushing chamber, this time, has broken a good product discharged from the gravel on the bottom; when to rely on two jaw plates together, so the material into the crushing chamber by two jaw plate with a rub of the extrusion force, and thus the role of material for bending and splitting so that the material broken. Crushing the material to achieve the whole process.
