Vertical shaft impact crusher with multiple shaping functions

Abstract

The invention relates to building material crushing devices, in particular to a vertical shaft impact crusher with multiple shaping functions. The vertical shaft impact crusher is simple in structureand reasonable in design and comprises a crushing chamber and a rotor, wherein a crushing cavity is formed in the crushing chamber, and the rotor is rotatably arranged in the crushing chamber througha spindle. A discharge port is arranged at the bottom of the crushing cavity, a dispensing chamber is arranged at the top of the crushing chamber, a dispensing inner cylinder is arranged in the dispensing chamber, and a bulk tray is arranged at the center of an opening of the dispensing inner cylinder. The side wall of the dispensing inner cylinder is heightened, the top of the side wall of the dispensing inner cylinder is higher than the height of the bulk tray, an outlet at the bottom of the dispensing inner cylinder corresponds to an inlet of the rotor, the radius of the rotor is increased,and the distance between the outer side wall of the rotor and the inner wall of the crushing cavity is increased. The circumference of the rotor is provided with grinding plates evenly distributed, rotor ejection ports are left between the grinding plates, and the ratio of the surface area of the sides of the grinding plates to the rotating surface area of the rotor is 4-7:10. The collision probability of a material striking back and the rotor is increased, and the shaping of the ridge corners of the material is improved.

Description

technical field [0001] The invention relates to building material crushing equipment, in particular to a vertical shaft impact crusher with simple structure and reasonable design with multiple shaping functions. Background technique [0002] The vertical shaft impact crusher is a kind of high-speed crushing equipment capable of preparing building materials-machine-made sand and gravel. It is composed of a rotor, a crushing chamber, a transmission system and a bracket. After entering the rotor, the material is accelerated and then ejected. The material liner or impact block in the crushing chamber impacts to achieve material crushing. In the actual process of preparing machine-made sand, the existing equipment generally has the following problems: the fluidity of the finished machine-made sand is poor; Low proportion of gradation) High porosity and other problems, such as "Concrete Aggregate Preparation Engineering" to solve such problems, using equipment such as rod mills o...
