Equipment Introduction Series single-stage crusher is suitable for crushing various brittle ores with compressive strength, such as limestone, shale, gypsum, coal, argillaceous siltstone and mixtures of limestone and clay. It can crush large pieces of ore at one time to the required particle size for grinding, thereby replacing the traditional two-stage crushing, simplifying the process and saving production costs. This series of hammer crushers is a special crusher for cement production. It is suitable for crushing limestone (marl) and clay mixtures. It can also be used for coal crushing. It is mainly used in cement production crushers, large-scale sand and gravel aggregate production and other projects. project.
Working Principle
The series of single-stage hammer crushers are mainly composed of rotors, bearings, discharge grates, impact plates, shells and driving parts. This is a type of upward impact hammer crusher, which mainly relies on the hammer head of the crusher to strike the ore strongly in the upper chamber. The impact of the ore on the impact liner and the collision between the ores cause the ore to be broken. After the raw ore is fed into the feed port of the crusher through heavy-duty feeding equipment (such as an adjustable-speed plate feeder), it falls into the crushing cavity between two high-speed counter-rotating rotors driven by a narrow belt and is impacted by the hammer head. was initially shattered by the blow. After the initial crushing, the materials are further crushed between the rotor and the impact plate during the downward movement, and then are shunted by the impact plate and enter two mutually symmetrical discharge areas. Finally, the lower material is formed by the grate and the rotor. The crushing chamber carries out final crushing until the particle size is smaller than the size of the grate gap and is discharged from the lower part of the machine chamber.
Performance characteristics
, Multi-stage crushing is converted into a single stage, specially designed to resist severe limestone wear conditions
, The crusher hammer adopts internationally advanced composite materials independently developed by our company, and the product The Mingda Gold Tooth super hammer head has a longer service life than high quality
. The use of our company's unique patented technology of stone-on-stone crushing cavity modification greatly increases the self-breaking ratio of materials, effectively reducing the wear load of the hammer head and grate plate
, The rotor adopts two-step super-hard surface deposition technology, which has a surfacing life more than twice that of conventional wear-resistant electrodes
The main shaft is made of military high-strength artillery steel/vacuum double-melted strength with a surplus of times
