Product DescriptionHigh Pressure Grinding Roll for CementThe High Pressure Grinding Roll (HPGR) is a highly efficient energy-saving grinding equipment, widely used as a pre-grinding system in cement plants. It significantly increases system output, reduces grinding power consumption, and improves overall efficiency of the production line. The material passes between two counter-rotating rolls under high pressure, generating micro-cracks that enhance subsequent grinding.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 for CementEnergy Efficient: Reduces grinding power consumption by 20–50%Increased Output: Improves vertical mill or ball mill throughputWear-Resistant Rolls: Long service life with alloy or carbide surfaceCompact Design: Ideal for system upgrades or retrofitsLow Noise & Dust: Environment-friendly operationHydraulic Control: Stable pressure regulation and roll gap adjustmentSpecificationParameter 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/Application FieldsCement pre-grinding systemsClinker and limestone crushingVertical mill energy-saving upgradesGrinding system transformation projectsPackaging & DeliveryCement pre-grinding systemsClinker and limestone crushingVertical mill energy-saving upgradesGrinding system transformation projectssCompany 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.
