A kind of impact type compound crusher

Abstract

The invention discloses an impact compound crusher, comprising: a cylinder body, a rotating shaft, a crushing hammer, a cover plate, an impact ring and a driving mechanism, one end of the cylinder body is open, the other end is closed, and the end surface of the closed end is provided with a mounting hole. and the feed port; one end of the rotating shaft extends into the cylinder, and the other end of the rotating shaft is located outside the cylinder and connected with the drive mechanism; the breaking hammer is installed on the rotating shaft; the cover is installed on the open end of the cylinder, and the cover and The cylinder cooperates to form a conical cavity that communicates with the inner cavity of the cylinder; the counter-attack ring is installed in the conical cavity, and the counter-attack ring includes a plurality of retaining rings arranged concentrically. The end far away from the cylinder is arranged at intervals, and the inner diameter of each retaining ring decreases successively from the end close to the cylinder to the end far away from the cylinder; a discharge port is provided on the cover plate. The present invention thus greatly improves the crushing effect rate of granular raw materials, and the finished particles have good uniformity and high quality.

Description

technical field [0001] The invention relates to the technical field of crushing, in particular to an impact compound crusher. Background technique [0002] The composite crusher is called composite crusher for short, and it is one of the commonly used equipment in crushing production line and sand making production line. Combined crusher is a kind of fine crushing equipment without sieve bars, which can be widely used in the fine crushing of raw materials and clinker in cement plants. It is especially suitable for the processing and crushing of hard limestone, dolomite, granite, basalt and other artificial sand or highway pavement stone. [0003] However, in the existing compound crushers, the crushing process of materials from the feed port to the discharge port can only pass through in one direction during the crushing process, and the crushing effect and the uniformity of the finished product particles after crushing are poor. Contents of the invention [0004] Based ...
