Main features

1. Roll surface technology (welding materials, equipment, and welding processes) uses hot welding for the roll surface, making maintenance of the wear-resistant layer more convenient. Effectively reducing the generation and propagation of microcracks during the welding process, the hardened layer has high hardness (>HRC58) and toughness, and the service life of the roller surface is over 8000 hours, with simple daily maintenance.
2. Adopting aviation hydraulic technology makes the hydraulic system of the roller press extremely reliable.
3. The hydraulic system of the roller press and the complete automatic control system can work together to achieve: load control of the main drive motor of the roller press; Control and automatic correction of left and right gap deviation between two rollers; Fault self diagnosis technology.
4. The supporting powder selection machine integrates the breaking, grading, and drying of the aggregate cake, and has the characteristics of low operating costs and high operating rates.
5. The supporting automatic control system adopts fuzzy control principle and is equipped with components from world-renowned suppliers.

Design and Configuration

Wear resistant lining
The pressure roller of PFG has a layer of wear-resistant lining that has been welded, which can be used for welding solid shafts or hot press fit bushings.
The worn surface can be restored by welding. If necessary, repair of damaged points or welding of the entire surface can be carried out without moving the roller.
Feeding control system
In order to facilitate the formation of extruded material cakes, the HRP roller press has an electric feeding control door, which can make the feeding start smooth and help adjust the output or energy consumption of the roller press. Setting up a feeding control door is beneficial when dealing with multiple types of materials, but it is necessary for forming a cake.
configuration option
The roller press can be used to form a grinding system in the following ways:
As a pre grinder, the roller press grinds the new feed, and the ground material then enters the ball mill grinding circuit.
As a semi final grinding equipment, the PFG roller press operates in a closed circuit together with the disperser and dynamic powder selector.
Fine materials are finally ground in a single chamber ball mill. In this configuration, the PFG roller press can be arranged more compactly and efficiently by using a two-stage powder selector to work together with the ball mill. For certain types of feed and certain final products, the PFG roller press can operate as a final grinding system without the need for a ball mill. The PFG roller press operates together with the two-stage powder selection machine in a closed circuit, which can result in lower operating and investment costs.
