Your Crushing Circuit Is Only as Strong as Its Primary Jaw

Every ton of material that enters your plant must first pass through the primary crusher. When that machine is undersized, poorly maintained, or lacks the throughput to match your downstream cone and screen circuit, the entire operation suffers. Industry data indicates that a bottleneck at the primary stage can reduce overall plant efficiency by 1525%, directly translating to lost revenue per operating hour. You are likely facing three specific challenges: excessive downtime from jaw plate wear on abrasive feed, inconsistent product sizing that forces recirculation loads above 30%, and high fuel consumption per ton when the crusher is forced to operate near its upper limit. Are you currently running a machine that requires frequent breaker intervention to clear bridging? Is your maintenance crew spending more time on toggle plate and bearing replacements than on preventive care? The right primary crusher should be the most reliable, predictable component in your circuit.

Produk Oorsig: The HighCapacity Mobile Jaw Crusher

This equipment is a trackmounted, dieselhydraulic primary jaw crusher designed for continuous, hightonnage processing of hard rock and recycled materials. It is engineered for a specific workflow: feed material is loaded via excavator or wheel loader into the vibrating grizzly feeder, which scalps fines and bypasses them directly to the discharge conveyor. Oversize material enters the deep, symmetrical crushing chamber where a fixed jaw and a moving jaw create a compression zone. The moving jaw, driven by an eccentric shaft, crushes material against the fixed jaw. The crushed product exits through a hydraulically adjustable closedside setting (CSS) at the base of the chamber. The entire unit is selfcontained with an onboard diesel engine, hydraulic drive for the feeder and conveyor, and a remotecontrol system for tracking and setup.

Toepassingsomvang: This machine is suitable for primary crushing of granite, basalt, riviergruis, and limestone with a compressive strength up to 400 MPa. It is also effective for processing reinforced concrete and asphalt rubble in demolition recycling applications.

Beperkings: This is not a secondary or tertiary crusher. It is not designed for producing a final, saleable aggregate product without downstream screening and cone or impact crushing. It requires a minimum feed size of 300mm to operate efficiently; excessive fines in the feed can reduce throughput. The machine is not suitable for wet, sticky clay materials without a specific fines bypass and cleaning system.

Toepassingsscenario's

Hard Rock Quarry (Graniet) | Uitdaging: 'n Steengroef in Noorweë het ondervind 12 hours of downtime per month due to jaw die breakage and bearing failures on a 15yearold stationary jaw. The recirculation load on their secondary cone was 35%, limiting overall plant output to 400 tph. | Oplossing: Replaced the stationary unit with the HighCapacity Mobile Jaw Crusher, set at a 150mm CSS. The variable speed feeder was set to bypass all material under 100mm. | Resultate: Deurset het toegeneem tot 580 tph. Hersirkulasielading het gedaal tot 18%. Jaw die life extended from 75,000 ton aan 95,000 ton. Monthly downtime reduced to 4 ure.

Sloop Herwinning (Beton & Rebar) | Uitdaging: A recycling yard in Chicago was processing 300 tph of mixed concrete rubble. The existing impact crusher was experiencing excessive wear on blow bars from rebar, kosteberekening $8,000 per week in replacement parts. | Oplossing: Installed the mobile jaw crusher as a primary, set at a 100mm CSS. The grizzly feeder scalped rebar and fines, while the jaw crushed the concrete. A magnetic separator was added to the discharge conveyor. | Resultate: Blow bar costs on the downstream impactor dropped by 70%. Total plant throughput increased to 450 tph. The jaw crusher processed 120,000 tons of concrete before requiring die replacement.

Riviergruisverwerking | Uitdaging: A contractor in Brazil needed to process 500 tph of abrasive river gravel with high silica content. Their existing cone crusher was being used as a primary, causing frequent bowl liner changes. | Oplossing: Deployed the mobile jaw crusher as a primary, set at a 125mm CSS. The jaw's deep chamber handled the abrasive feed without the high wear rates seen in a cone. | Resultate: Liner life on the downstream cone increased by 300%. The jaw crusher processed 150,000 tons before die change. Overall operating cost per ton decreased by 18%.

Gereelde vrae

V: Can this crusher handle material with high clay content?
A: The machine is not designed for wet, klewerige klei. The grizzly feeder can bypass some fines, but clay can pack in the crushing chamber and reduce throughput. For clayheavy feed, we recommend a feeder with a grizzly section and a separate fines conveyor, or a different primary crusher type.

V: What is the expected lifespan of the jaw dies on abrasive granite?
A: Field data from granite operations with a silica content of 3040% shows jaw die life between 90,000 en 110,000 ton per stel, depending on the CSS setting. A tighter CSS (75mm) will reduce die life by approximately 15%.

V: How long does it take to move this machine between sites?
A: The machine is selfpropelled on tracks at a speed of 1.5 km/h. For a move within a quarry, you can reposition in 1520 minute. For road transport, it requires a lowboy trailer and typically takes 23 hours to load and secure.

V: What is the typical fuel consumption per ton?
A: In dieselhydraulic mode, the machine consumes approximately 0.03 aan 0.04 gallons per ton processed. In dieselelectric hybrid mode, this drops to 0.018 aan 0.025 liter per ton.

V: Is the machine compatible with existing screening plants?
A: Ja. The discharge conveyor height of 3.8m is standard for feeding into most mobile or modular screen decks. The belt width of 1,200mm matches common downstream conveyor widths.

V: Wat is die tyd vir aflewering?
A: Standaard deurlooptyd is 1216 weke vanaf bestellingbevestiging. The Premium Package may require 1620 weeks due to the automation and telematics integration.

V: What financing options are available for a purchase?
A: We offer leasetoown terms from 36 aan 60 months with fixed interest rates. Operating leases with a residual value are also available. Seasonal payment schedules can be structured for operations that shut down during winter months.
