PDG- II type of roller crusher is my company experts for many years of mining machinery and equipment manufacturing and the wisdom of the correct decision-making. Is a with the international advanced level of high energy consumption equipment, a variety of ore crushing equipment plays an irreplaceable role in, the product widely used in cement, refractory materials, aluminum bauxite clinker, stone, diamond sand glass raw materials, building sand pebble sand and a variety of metallurgical mining industry.

Working principle

PDG-II of roller crusher is composed of two phase synchronous rotation extrusion roller, a fixed roller, a movable roller.

Material from the two to the top of the roller, the extrusion roll into the roll, by the high pressure of 50-200MPa, the ideal size from the machine discharge.

Material from the surface of roller bit, by roller force increased gradually, discharged from the maximum pressure can reach 200Mpa. material, in addition to contain a certain proportion of powdery material and other particles in the internal, produce lots of cracks, in further crushing process, can greatly reduce grinding energy.

Main features

In the grinding system equipment PDG-II on the roller crusher can make grinding equipment production capacity can be fully played, generally can increase production 30%-40%, total energy consumption can be reduced by 20%-30%.

Compact structure, light weight, small size, for the same production capacity requirements of the grinding system, equipment PDG-II on the roller crusher can significantly save investment.

Simple structure, small footprint, easy operation and maintenance.

The interior is equipped with a dust proof plate, sealing performance is good, to avoid the broken after the fine material of the splash, dust, low noise, working environment is greatly improved.

The abrasive roller body is re designed and optimized, and the equipment is used for life without changing the roller body of the mill, and the old type of the roller machine needs to be disassembled for a year.

The machine grinding roller is provided with a replaceable wear resistant lining board, the wear-resistant lining board adopts the domestic advanced wear-resistant material, has the advantages of long service life, not easy damage, convenient maintenance and the like. Continuous service life of up to more than one year, wear serious, move the boot cover can be replaced. Maintenance of small, low cost, which is any other type of crusher can not match the.

The machine is equipped with safety protection device, when there are unexpected metallic iron pieces into the crushing chamber, door device, iron leakage equipment normal operation.

The machine abrasive roller roll gap between 20mm ~ 1mm adjustable, according to the requirements of the broken particle size of the roller seam adjustment, broken particle size can be reliable control, all with the ideal particle size from the bottom of the broken cavity.

Simple and reasonable structure, low running cost, stable operation, high efficiency and energy saving, high crushing efficiency, the size of the material can be adjusted.

This machine is the working principle of low speed and high pressure to roll extrusion. Material by crushing machine is arranged on the upper part of the vertical into broken cavity, produced by between two and strong pressure extrusion broken. Most of the material has become a powder, the inside of the small fraction of a particulate material surplus has produced lots of cracks. In the further grinding process, the grinding energy consumption can be reduced, and the output can be improved.
