    Shandong Shengya Machinery Co., Ltd. specializing in the production of various types of brick, brick machine, brick machine, hollow brick, pavement brick and other equipment of the old brick factory.
     Crusher is a kind of machinery for crushing stones, broken and its characters: a broken chunk of material to become small pieces of material to make the process. This process is external (human, mechanical strength, power, chemical energy, nuclear or other methods) applied to the material to be broken, to overcome the material cohesion between the molecules, so that if the bulk material is split into a thousand pieces. The rock is brittle material, which in a small deformation occurs on destruction.
    Currently in the industry is the use of mechanical force to crush rock, the use of mechanical force method of breaking rock are the following:
    (1) crushing: crushing surface between two rocks placed will, after the application of pressure, the rock due to the compressive stress reaches its compressive strength and broken.
    (2) chipping: When using a flat work surface and squeeze with a sharp edge rock, the rock will split along the direction of the pressure line. Fart blanket is due to splitting tensile stresses on the plane to meet or exceed the tensile strength of the rock. The tensile strength of rock much smaller than the compressive strength.
    (3) fracture: the destruction of the rock is subject to bending. The crushed rock is subjected to concentrated load of two point or fulcrum beams. When the rock reaches the bending stress bending rock strength, rock namely break.
    (4) ground: when subject to certain pressure and shear forces between the surface of the rocks and the movement, its shear stress reaches the shear strength of the rock, namely crushed rock. Low grinding efficiency, energy consumption.
    (3) Impact crusher: rock by the impact of high-speed rotating parts broken. It's crushing force is transient effects, its high crushing efficiency, glass broken than large, less energy consumption.
     Shandong Shengya Machinery Co., Ltd. has been committed cement products machinery development, production and sales, with advanced equipment, superb technical expertise and two decades of experience, the company has always been at the forefront of research and development center block molding machine market development , concerned about the advanced technology at home and abroad, to develop products for different investment needs of users, mainly block making machine, hydraulic tile machine, cement pipe machine, mixer, hanging roller machine, telephone poles machine equipment.
