roll crusher used in
roll crusher for coal, metallurgy, mining, chemicals, building materials industry is more suitable for large-scale coal mine or coal preparation plant (including waste rock) is broken. our production of mining equipment, construction machinery, such as jaw crusher, impact crusher, sbm cone crusher, mobile crusher, hammer breaker, as well as vertical mill, high pressure mill, ultrafine mill, raymond mill, ball mill is a very good crushing equipment and milling equipment. our company specializes in processing equipment, mineral processing, beneficiation process, mineral processing equipment price consulting services. and provide you with the most reasonable solution dressing: crusher, milling machine, vibrating screen, conveyors and more.
roll crusher is divided into two-toothed roll crusher and four roller crusher teeth two series, double roll crusher mechanical spring (2pcm), the teeth roll crusher according to the material properties and crushing requirements were equipped with coarse teeth or the teeth roll roll, four roll crusher teeth actually consists of two double teeth roll crusher combination.roll crusher is small, broken than large (5-8), low noise, simple structure, easy maintenance advantages of high productivity, uniform particle size by crushing, grinding too low, easy maintenance, overload protection sensitivity , safe and reliable.
double roll crusher
double roll crusher is the use of two separate drive rollers, the relative rotation of the extrusion and rolling mill the shear force to breaker the material. when the material enters the machine after the crushing chamber, the material by rotating rollers nie force, forced through the material between two rollers, the rollers squeeze the same time by rolling and cutting grinding, the material began to fracture, post-fragmentation small particles along the rotating cutting rollers, two rollers through the gap, thrown to the bottom of the machine over the gap of the large particles of materials, continue to be broken into small particles discharged.
roll crusher manufacturers
double equipment company have established a whole production chain, of which main products cover stone crushing & screening equipments: jaw crusher, cone crusher, impact crusher, vertical impact crusher, hammer crusher, vibrating feeder, oscillating screen, sand washer, belt conveyor;and grinding machinery: raymond mill, high-pressure suspension mill, ultrafine and roller mill, ball mill and so on.
Crusher main content and attention matters of the rotor spindle repair, the dangerous area of crusher rotor, main contents of the rotor overhaul
where is the dangerous area of crusher rotor mainly distributed?
according to the analogue simulation stress analysis cloud chart, we can see clearly that the dangerous areas of crusher rotor are mainly distributed in hammer rockk, hammer shaft hole on hammer dish, hammer dish outer edge, hammer shaft and mainshaft bearing shaft shoulder, etc.
what are the main contents of the rotor overhaul are?
the main contents of rotor overhaul are: checking on and bending repair straightening hammers and main shaft of the hammer crusher, lock device checking and repairing, the repair of rotor and outer edge of hammer and hammer dish replacement, repair and replacement and gradation of hammer, cleaning and maintenance of bearing and bearing pedestal and sealing device.
what are the main content and attention matters of the rotor spindle repair are?
due to the larger axial neck, heating difficulty, and heating time is long, and the temperature is not easy to be controlled uniformly, straightening should be paid attention to the five following points:
1、 the pressured straightening force should not be so large, to prevent the spindle from cracking on the hidden trouble flaws.
2、 when bending quantity is larger, straightening should be done by several times.
3、 correcting numerical should be properly over the shaft bending value to eliminate the influence of rebound deformation when the straightening force is removed from the shaft.
4、when in straightening, straightening force should be kept for a period of time. at the same time, using small plumb bob to knock the axial plane gently and these operations can relieve residual stress and prevent deformation occur ing when the straightening force is removed.
5、 in the straightening process, shaft bending value should be measured continually until complying with the standards. when the shaft is φ200-300, the shaft bending value should not be over 0.06mm. for the straightened shaft, bending value should not be over 0.1-0.15 mm.
hard-rock crushers type ap-kh / ap-kmh
ideal for processing highlyabrasive materials to generate an appropriate cubical, stressand crack-free product.
optimum crushing chamber configuration, high capacity, high crushing efficiency, reduced wear rates. extremely robust and economical. ease of operation and a consistent product standard thanks to hydraulically actuated impact aprons (optional). haztronic electronic control system for production selection of computerstored recipes according to requirements (optional).
secondary / tertiary impactors type ap-vmh-r / ap-kvh-r
impactors for chippings and mechanical sand.
granulometry range: coarse and fine chippings, mechanical sand with one machine only. reversible rotor. hydraulically adjustable impact apron and grinding path. large maintenance doors.
roll crushers / roller mills type wb / wm
smooth crushing of soft to medium-hard material with a low percentage of fines.
sbm roll crushers and mills are ideally suited to the smooth crushing of soft- to medium-hard materials with a low percentage of fines in the product. they have also proved their effectiveness in the crushing of cohesive materials with a high moisture content.
hydraulically-controlled floating roll. a high degree of safety and minimum maintenance requirement.hydraulic support of the floating roll, which ensures the retraction of the floating roll in case of an overload or feeding of unbreakerable pieces.
