Working Principle

  ◎ Based on the principle of high-pressure material layer crushing, two opposing extrusion rollers, supported by a hydraulic system, apply an extrusion force to the material rolled between the two rollers that is much greater than its compressive strength, thereby achieving efficient ultrafine crushing and grinding.

  ◎ After being milled by high-pressure roller mill, some of the material has reached the required particle size and can be selected in time by screening, air separation and other methods to avoid over-grinding. The particles that have not reached the target particle size are also filled with a large number of microcracks, which greatly improves their grindability and thus can significantly reduce the grinding energy consumption of subsequent processes.

Technological Advantages

  Custom-designed high-pressure roller mill systems for ore processing, tailored to the specific characteristics of each project, offer key advantages including:

  ◎ Based on the ore's strength and grindability, the load-bearing structure and drive system of the high-pressure roller mill are configured to ensure that the high-pressure roller mill can handle the ore with ease.

  ◎ Based on the hardness and abrasiveness of the ore, select a reasonable wear-resistant treatment method for the roller surface to ensure the roller surface life.

  ◎ Select an appropriate grinding fineness based on the mineral phase.


Technical Features

1. Anti-impact, Corrective Feeding Device: A Key Technology for High Efficiency and High Yield

◎ The high-pressure roller mill features a unique anti-impact, corrective feeding device that effectively controls the smooth entry of material into the mill, stabilizes the working roller gap and operating current, and prevents material collapse that could cause the mill to stop. Feed correction is achieved through differential adjustment of multiple feed valve plates, resulting in a balance between the working roller gap, cylinder pressure, and two-roller current, thus achieving high efficiency across the entire grinding process in both spatial and temporal dimensions.

2.Safe and Reliable Hydraulic Loading System

◎ The system adopts a dual high-pressure oil source with mutual backup, ensuring extremely high reliability.。 

◎ The system features fast pressurization speed and good pressure holding effect, ensuring stable working pressure of the high-pressure roller mill. 

◎ The system adopts multiple buffer designs to absorb the impact load caused by fluctuations in high-pressure roller mill operating conditions, improving the comfort of roller mill operation. 

◎ In case of emergency, it can quickly release pressure to ensure equipment safety.

3. Intelligent Main Control System

  The main control system of the high-pressure roller mill is the core component for the automated and intelligent management of the high-pressure roller mill. This system: 

  ◎ User-friendly interface, simple operation;

  ◎ One-button start, automatic management;

  ◎ Intelligent Optimization of Operating Parameters;

  ◎ Automatic Diagnosis of Common Faults.

4. High-Strength Frame

  ◎ The frame is available in two types: modular frame and welded frame. Both adopt a modular design, featuring high strength, good rigidity, and easy assembly and disassembly.

5. Safe and Reliable Roller System

  ◎ The roller surface can be made of long-life, disposable stud rollers, or economical and durable weld overlay rollers can be used.

  ◎ Large bearing selection with high strength reserve.

  ◎ The bearing axial positioning is reasonable, and axial displacement will not occur.

6. Roller System Side Pulling System

  ◎ Adopts a combined frame and side-pull system. The roller system is maintained using a track + maintenance trolley + hoisting system, greatly simplifying the maintenance of large high-pressure roller mills, saving maintenance time, and reducing maintenance equipment and infrastructure investment.
