used Hammer Crusher introduction
used hammer crusher
this hammer crusher is mainly component of casing, rotor, hammers and bars. the case is divided into two parts: up and down, which is connected by welding the cut steel; other parts are connected by screws. the one inside of case is high manganese steel lining board, which is easy to change when wore out. there are several hammers in the spindle, which make up of rotor together with turntable and wear hammer shaft. it works through motor and v-belt to drive spindle and rotor rotating, so that centrifugal force producing by the hammer rotating spread out. then when the big material was put into crushing chamber, it was crush by the high speed hammer. afer those process, the standard material was screen out by down bar and non-standard one was left on the crushing chamber and crush again. in order to avoid clogging, humidity of crushed material should below 10%-15%.
hammer crusher is widely used in metallurgy, mining, chemical, cement, coal gangue, construction, sand, refractory material, ceramic and other industrial and mining enterprises, engaged in breaking and crushing the material in the operation. it is mainly suitable for crushing various soft and hard ore. whose compression strength is not higher than 320mpa (mpa),such as coal, salt, chalk, gypsum, blocks, lizenithne, etc.the main working part of hammer crusher is rotors with hammer. the rotors consist of main shaft, disk, pin shaft and hammers. the motor drives the rotors to rotate quickly in the crushing cavity. raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size.

used hammer crusher working principle
used hammer crusher
hammer crusher consists mainly of frame, rotor, hammers and grizzly bars and other components. the frame includes upper part and lower parts, which are welded by steel plates after cutting, the remaining parts bolted into one. high manganese steel liners are studded with inside the frame, to facilitate replacement for a new liners after worn; on the main shaft are installed several groups of the spindle distribution of the hammers, which consists of rotor with the axle of hammers and rotary table. the host drives the main shaft through the motor and v-belt driven spindle to rotate the rotor, generating the centrifugal force, then driving all hammers stretch around. the bulks of material feed into the crushing chamber, will be crushed by the hammers at a high-speed movement. the broken material requested will be passed the grizzly bars at the lower part and discharged, the unbroken rest will be left in the chamber to be crushed repeatedly by the hammers and iron plates until it can reach the requested standard. to avoid clogging, the water content of the material to be crushed not more than 5%.
used hammer crusher structure & features
hammer crusher is composed mainly by the frame, rotor, impact iron bar, grid bar and other components. the frame consists of upper and lower parts, which are welded together after cutting by a steel plate, the remaining parts connected into a whole by bolts.
1. high production and high crushing ratio.
2. low power consumption, homogeneous particle size.
3. simple, compact and light mechanical structure.
4. low investment costs and convenient management.

used hammer crusher project in mexico
the project is an advanced stage copper/cobalt/zinc/manganese development located in baja california sur, mexico.
ore will be mined by both underground and open pit mining methods. it will crush and mill ore in sea water.
the dissolved metals will be recovered at high efficiency from the wash solution and concentrated in four independent solvent extraction circuits, two electrowinning circuits and a fluid bed drying operation to produce high-quality copper and cobalt metal cathode and zinc sulphate monohydrate crystals.
in the crushing and milling process, sbm machinery supplies hammer crusher as quaternary crusher in the circuit. our crushing machine can crush the run-of-mine ores into 3mm in diameter with low return rate.
