Working principle

The two rollers have wedge or gasket adjusting device, wedge device with the top adjustment bolt, when the adjustment bolt wedge block upward pull up, wedge will activities roller top from fixed wheel, two roller gap becomes larger, the discharge size becomes larger, when the wedge block down, activity roller compression spring (or pressing oil cylinder) under the action of two gap becomes smaller, the discharge size becomes smaller. Gasket device is through increase or decrease the number of gasket thickness to adjust the size of the discharge size, when adding gasket will make two roller wheel gap bigger, when reduce gasket will make two roller wheel clearance decrescent, the discharge size becomes smaller

Application

double roll crusher is suitable for crushing medium, high hardness materials in metallurgy, building materials, refractory materials. This series of crusher is mainly composed of a roller, the roller support bearings, compaction and adjusting device and the drive components.

The grain size regulation: wedge or gasket adjusting device is arranged between the two roller, the top of the wedge device with adjusting bolt, when adjust the adjusting bolt will pull up the wedge, the wedge will move the activities roller from fixed wheel.

Product feature

1, in the sand making industry, equipped with PDG-III type roll crusher, can increase the output of 30%-40%, the total energy consumption can be reduced by 20%-30%.
2, compact structure, light weight, small size, for the same production capacity requirements of the sand system, equipped with PDG-III type roller crusher can significantly save investment.
3, simple structure, small occupation space, convenient operation and maintenance.
4. The interior is equipped with dustproof board, which has good sealing performance, avoids the splashing of small materials after crushing, and has less dust and can carry water operation. The work noise is low, and the working environment has been greatly improved.
5, the roll body to re optimize the design, the equipment does not need to change the roll for life, and the old type of roll machine use a year, you need to disassemble the overhaul, replace the roller.
6, the roll crusher is equipped with replaceable wear-resistant lining board, wear-resisting lining board adopts advanced wear-resistant materials, with long service life, not easy to damage, convenient maintenance and so on. Continuous service life of up to one year or more, when the wear is serious, remove the boot cover can be replaced. Small amount of maintenance, low cost, this is any other domestic types of crusher can not match.
7. The roller crusher is equipped with safety protection device. When an accidental metal piece enters the crushing chamber, the protective device moves and the iron piece leaks out and the equipment runs normally
8, the roll crusher roll body gap between 1mm ~ 20mm arbitrary adjustable, according to the requirements of crushing size, after adjusting the roll gap, crushing size can be reliably controlled, all the ideal particle size from the crushing chamber below the discharge.
9. The utility model has the advantages of simple and reasonable structure, low running cost, stable operation, high efficiency and energy saving, high crushing efficiency and large crushing ratio.
10, roll crusher is low speed, high pressure roller extrusion work principle.
