When plant operators and buyers search for a high-capacity double roll crusher capable of delivering 400 T/H, the correct engineering answer is the flagship 2PGY2000×1200 hydraulic double roll crusher. Featuring massive 2000\text{mm} rolls, a 120mm feed limit, and a rated capacity of 300–400 T/H, this model stands at the pinnacle of heavy-duty roll comminution. This article details why the 2PGY2000×1200 is selected for high-tonnage lines, presents the full reference model range from laboratory to mega-plant sizes, outlines a 400 T/H plant flowsheet, and provides expert FAQ guidance.
When buyers search for a double roll crusher with a 400 T/H capacity, the answer is not a “magic universal model,” but one flagship size engineered specifically to achieve it: the 2PGY2000×1200 hydraulic double roll crusher—featuring a roll diameter of 2000text{mm}, a roll width of 1200text{mm}, an allowable feed size up to 120text{mm}, and a rated capacity of 300–400 T/H. If your industrial project demands a steady 400 T/H, this is the precise model to quote. Below, we examine why, review the complete model range, and outline how to engineer a high-capacity crushing line around it.
Note: All capacity figures are nominal reference values; actual output depends on material hardness, feed size, and closed-side setting. Final equipment selection is confirmed via formal project engineering calculations 【Custom Parameters Available】.
HSM 2PGY2000×1200 Heavy-Duty Hydraulic Double Roll Crusher
1. Why the 2PGY2000×1200 Is Engineered for 400 T/H
- 1. Operating with Margin, Not at the Ceiling: Running any crusher at its absolute maximum limit is poor engineering—feed surges or harder ore veins immediately drag output down. The 2000×1200 is rated at 300–400 T/H, positioning a 400 T/H requirement at the upper boundary of its working range. For round-the-clock continuous operation, pairing it with stable volumetric feeding or deploying a dual-unit parallel layout is strongly recommended 【Custom Parameters Available】.
- 2. Hydraulic Protection Handles Tramp Metal: At this massive capacity class, uncrushable tramp objects (such as heavy excavator bucket teeth or drill steel fragments) represent severe operational risks. The hydraulic relief system allows the movable roll to retract instantly to pass tramp iron and reset automatically, protecting roll shells and main drive shafts from catastrophic fracture while preventing unplanned shutdowns.
- 3. Large Roll Diameter for Stable Nip Angles: The 2000\text{mm} rolls accept feed sizes up to 120\text{mm} with a deep, highly stable nip angle. This minimizes material slippage, reduces flat-plate rejects, and ensures uniform product gradation even at high throughput rates.
- 4. Adjustable Sizing & Low Fines Generation: Finished product sizing is regulated via precise inter-roll gap adjustments. The low-speed compression principle generates minimal over-grinding—a critical advantage when crushed ore feeds downstream grinding ball mills, where excess ultra-fine slimes waste energy and reduce mineral recovery.

Selection Rule of Thumb: Choose a model whose mid-range capacity covers your target—not one whose ceiling equals it. A guaranteed 400 T/H requirement can alternatively be met by deploying two 2PGY1500×1200 units (200–250 T/H each) operating in parallel, an approach that adds essential operational redundancy for scheduled maintenance rotations.

3. Typical Plant Configuration at 400 T/H
Standard Proven Flowsheet:
Vibrating Feeder rightarrow Jaw Crusher (Primary Coarse Reduction) rightarrow Cone Crusher (Secondary Medium Reduction) rightarrow 2PGY2000×1200 Double Roll Crusher (Tertiary Fine Crushing) rightarrow Circular Vibrating Screen (Closed-Circuit Oversize Return Loop) rightarrow Finished Product / Ball Mill Feed.
Two Critical Engineering Notes:
- Control Feed Top Size: The double roll crusher is a precision fine-reduction machine. Oversize boulders must be reduced upstream by primary jaw and secondary cone stages.
- Enforce Closed-Circuit Screening: Routing crushed material across vibrating screens with oversized particles returned for re-crushing maintains stable top-size limits and prevents operators from dangerously narrowing roll gaps at the expense of throughput.
4. Frequently Asked Questions
Q: Can a single machine guarantee 400 T/H when processing hard ore?
A: 300–400 T/H represents the nominal engineering rating. On extremely hard, abrasive ores, realistic output depends strictly on feed lump dimensions and required product fineness. Send us your material data for exact engineering calculation, or let us quote a dual-unit parallel layout to guarantee tonnage with complete maintenance redundancy 【Custom Parameters Available】.
Q: What wear parts are involved in high-capacity roll crushers?
A: There are no hammer heads or impact shoes. The roller shells represent the primary wear components—manufactured from heavy-duty high-chromium alloys for hard-rock service, wearing evenly along a linear profile, and replaceable individually without major machine overhauls 【Custom Parameters Available】.
Q: What is the motor power rating for the 2000×1200 model?
A: The 2000×1200 utilizes a robust dual-motor drive system; exact kilowatt ratings are engineered and confirmed alongside your formal quotation based on your specific application and ore hardness 【Custom Parameters Available】.
