Reaction type compound crusher

Abstract

The invention discloses a reaction type compound crusher which comprises a cylinder, a rotating shaft, a crushing hammer, a cover plate, a reaction ring and a driving mechanism. One end of the cylinder is open, and the other end of the cylinder is closed. An installation hole and a feeding inlet are formed in the end face of the closed end. One end of the rotating shaft stretches into the cylinder, and the other end of the rotating shaft is located outside the cylinder and is in transmission connection with the driving mechanism. The crushing hammer is installed on the rotating shaft. The cover plate is installed at the open end of the cylinder. The cover plate and the cylinder are matched to form a conical cavity communicated with an inner cavity of the cylinder. The reaction ring is installed inside the conical cavity. The reaction ring comprises a plurality of concentrically-arranged check rings. The check rings are arranged inside the conical cavity at intervals from the end close to the cylinder to the end far away from the cylinder. The inner diameters of the check rings are gradually decreased in sequence from the end close to the cylinder to the end far away from the cylinder. A discharging outlet is formed in the cover plate. Accordingly, the crushing effect rate of granular materials is greatly increased, the uniformity of finished granules is good, and the quality is high.

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 ...
