Gear-roll crusher is suitable for coal, metallurgy, mining,
chemical industry and construction material etc. industries, and
even more suitable to break the raw coal (including gangue) of
large coal mine or coal dressing plant.
The machine has the advantages of small volume, big breaking ratio
(5-8), low noise, simple structure, easy to maintain, and the
characteristics of high productivity (higher 1-2 times than
domestic 2PGC gear-roll crusher), even discharged grain size, low
over-breaking percent, easy to maintain, sensitive over-load
protection, safe and reliable etc. The working principle of this
machine is that special wearable gear rollers run face to face in
high speed to break the material.
This double-gear roll crusher is driven by universal coupling, the
gap between rollers can be adjusted by add or reduce washers. The
main parts are fixed roller, mobile roller, reducer, universal
coupling. Adopting sliding bearing with the advantages of steady
driving, and very convenient for maintenance.
The new strong double-gear roll crusher designed by our company has
the advantages of compact structure, big breaking ratio (5-8), low
energy consumption, low noise, simple structure, easy to maintain,
and the characteristics of high productivity (higher 1-2 times than
domestic 2PGC gear-roll crusher), even discharged grain size, low
over-breaking percent, easy to maintain, sensitive over-load
protection, safe and reliable etc.， which filled the gap in
domestic same industry, and its main performance index are among
the top level of domestic industry. The main innovation
aspects：（1）for the teeth plate is alloy material of high wearable
and high strength performance, which prolong the service life of
crusher；（2）improve the teeth height and teeth pitch on the basis of
former crusher, and in this way the breaking ability is enhanced
greatly；（3）upgrade the lubrication oil system, equip the dry oil
lubrication station, make sure the automatic oil filling activity
can be achieved when starting the machine；（4）has the auto-alarming
function, if the other parts of lubrication oil have some problems,
then it can alarm automatically.
