High Pressure Grinding Roll Hpgr for Ore and Cement Crushing¹

Product DescriptionHigh Pressure Grinding Roll (HPGR) High-pressure roller press is a new type of energy-saving grinding equipment, also known as extrusion mill, roller mill or roller press. This equipment can replace the traditional ball mill pre-grinding system with high energy consumption and low efficiency, and at the same time reduce steel consumption and working noise. It is suitable for new plant construction and can also be used for technical renovation of old plants, and can increase the output of the production system by 30% to 50%.High Pressure Grinding Roll (HPGR) The High Pressure Grinding Roll (HPGR) produced by Shanghai Yingyong Machinery Co Ltd (SYM) is an energy-efficient crushing equipment designed for fine and ultra-fine grinding of hard ores and cement materials. It uses two counter-rotating rollers to apply high pressure on the feed material, reducing it by inter-particle crushing and minimizing over-grinding. HPGR is widely used in mining, cement, and metallurgy industries.SYM ServicesOne stop EPC service engineering procurement and constructionOn site installation and commissioningTechnical training and operation guidanceSpare parts support and after sales maintenanceKey FeaturesHigh Pressure Grinding Roll (HPGR) Energy Efficient: Reduces power consumption up to 30–50% compared to traditional millsHigh Throughput: Suitable for large-scale ore processing linesFine Product Size: Produces uniform particle size distribution with minimal over-crushingLow Wear Cost: Long service life of rollers with tungsten carbide or alloy liningCompact Structure: Space-saving and simple installationFlexible Design: Can be integrated into new or existing systemsApplication FieldsHard rock mining: gold, copper, iron ore, and diamond beneficiationCement industry: clinker pre-grindingPelletizing plants: feed material preparationLimestone and slag grindingMetallurgical processes requiring fine crushingCustomization OptionsDifferent roller surface types: smooth, stud-lined, or groovedWater cooling or air-cooling systemsSide-sealing device to reduce dustVibration monitoring and automatic pressure controlCan be combined with ball mills or classifiers in grinding circuitsSpecificationParameter  Value Range  UnitCapacity20 – 200tons/hourFeed Size≤ 50mmProduct Size2 – 10mmRoller Diameter500 – 1500mmRoller Width200 – 1200mmWorking Pressure50 – 150MPaDrive Power2 x 75 – 2 x 630kWRoller Surface TypeStud-lined or smooth/Control SystemPLC or DCS/Company ProfileWhy Choose SYM Machinery?Over 10 years of experience in rotary kiln manufacturing and designStrict quality control and international standard certificationsProfessional technical support and after-sales serviceCustomized solutions to suit your raw materials and production capacityFAQFrequently Asked QuestionsQ1: What is the advantage of HPGR over ball mill?A1: HPGR offers higher efficiency, lower energy use, and better product fineness control.Q2: What materials can be processed by HPGR?A2: Hard ores such as gold, iron, copper, bauxite, as well as cement clinker and slag.Q3: How long do the rollers last?A3: With stud-lined tungsten carbide, roller life can exceed 10,000 hours depending on material hardness.Q4: Can I integrate HPGR into my current plant?A4: Yes, SYM can customize the HPGR to fit your existing crushing and grinding circuits.Q5: Do you provide spare parts and service?A5: Yes.
