PG Double-Roller Crusher

The PG Double-Roller Crusher uses two counter-rotating rollers to crush material by compression. Its compact structure, adjustable roll gap and replaceable roller shells make it easy to install and maintain. A hydraulic or spring protection system allows uncrushable material to pass through, helping prevent equipment damage. It is suitable for high-capacity applications requiring a relatively fine product size.

Product Features:

Compact Structural Design; Adjustable Crushing Ratio and Roll Gap; High Capacity with Fine Output Size; Hydraulic or Spring Overload Protection; Replaceable Roller Shells; Low Noise and Operating Cost; Reliable Continuous Operation; Easy Installation and Maintenance.

Details Performance

Optimized Impeller Enhances Efficiency By 30% And Reduces Wear By 40%

Through systematic mechanical analysis and verification, Compared with the traditional sand makers, VSI5X Sand Maker obviously increases the material throughput and ratio of crushing, and enhances the working efficiency by 30%-60%. The wear costs of vulnerable parts reduce by more than 40%.

Hydraulic Device to Open the Cover Automatically Reduces Maintenance Costs

In consideration of the maintenance and part replacement during the production of the sand maker, By only pressing a button, users can open the top cover of the machine to carry out following operations. So, this system greatly saves labor costs and enhances the service efficiency.

Split-Type Structure, Extended Service Life of Spare Parts

Based on the actual situations of production, we found that some spare parts like the periphery guard board and impact block always wear terribly at some specific points. So, to avoid this phenomenon, which not only greatly extends service life of quick-wear parts, but also reduces their using costs a lot.

Brand New Feed Mode

In consideration that customers may have two production demands (i.e. sand making and shaping) which require the switch between central feeding and fall feeding

Maintenance

Jaw Crusher - Installation

The jaw crusher is a large crusher installed and receives no-load testing in the manufacturer's workshop. However it is disassembled into components for transport.

Jaw crusher - Lubrication

1. To ensure normal operation and extend service life of the crusher, regular lubrication shall be performed.
2. Grease in the bearing block shall be replaced every 3 to 6 months.

Jaw Crusher - Troubleshooting

1. Movable jaw does not rotate while flywheel is rotating
2. Crushing plate shakes and makes collision noise

Crushing Production Line - Installation

Preparation before foundation concrete placement
1. Set markings for placement thickness control, for example, horizontal standard piles or elevation piles.
