Abstract

The invention discloses a compound crusher. The compound crusher comprises a housing. A material distribution device is fixed to the top of the housing. A material outlet is arranged at the bottom of the housing. A double-tooth roller structure for coarse crushing is installed in the housing. The double-tooth roller structure comprises a pair of parallel tooth rollers. The parallel tooth rollers comprise a front tooth roller and a rear tooth roller. An invertible impacting hammer structure for fine crushing is installed under the double-tooth roller structure in the housing. The invertible impacting hammer structure comprises a pair of rotors parallel to the tooth rollers. The rotors comprise a front rotor and a rear rotor. Impacting hammers are fixed to the rotors. Impacting plates are arranged at two sides of the rotors. A material guide cone is arranged between the tooth rollers and the rotors on the perpendicular bisector of the two tooth rollers. The compound crusher realizes coarse crushing and fine crushing two-stage operation, reduces an investment cost and an operation cost of equipment, has a large volume, is environmentally friendly, does not produce raised dust, prevents bonding and blocking, and is convenient for fast maintenance.

Description

technical field [0001] The invention relates to a crusher, especially a composite crusher suitable for crushing coal, coal gangue, limestone, slag, coke and other chemical raw materials in coal, metallurgy, building materials, mining, electric power and other departments at the front end of a circulating fluidized bed boiler. . Background technique [0002] Because of its wide range of applicable coal types, high degree of mechanization and automation, and low environmental pollution, circulating fluidized bed boilers have been used in some power plants in my country since the 1960s. Now they have been rapidly extended to coal, metallurgy, etc. , building materials, mining, electric power and other industrial fields. [0003] According to the current technology, in the coal conveying system at the front end of the circulating fluidized bed boiler, coal crushing generally adopts two stages of crushing: the first stage is coarse crushing, using ring hammer crusher or double-to...
