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. This kind of crusher is a new product independently designed by our company on the basis of consulting the structure principle of overseas crusher.
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 main innovation aspectsï¼
ï¼1ï¼for the teeth plate is alloy material of high wearable and high strength performance, which prolongthe service life of crusherï¼
ï¼2ï¼improve the teeth height and teeth pitch on the basis of former crusher, and in this way thebreaking ability is enhanced greatlyï¼
ï¼3ï¼upgrade the lubrication oil system, equip the dry oil lubrication station, make sure theautomatic oil filling activity can be achieved when starting the machineï¼
ï¼4ï¼has the auto-alarming function, if the other parts of lubrication oil have some problems, then it can alarm automatically.
