Is Your Primary Crushing Stage a Bottleneck for Your Entire Operation?

Untuk pengurus loji dan kontraktor kejuruteraan, the primary jaw crusher is the gatekeeper of your entire mineral processing circuit. When it fails, everything stops. Anda menghadapi tiga cabaran kritikal:

1. Downtime yang tidak dirancang: A seized bearing or a cracked toggle plate can halt production for 1248 jam. At a throughput of 500 tan per jam, yang mewakili $150,000 ke $600,000 dalam pendapatan yang hilang setiap kejadian.
2. Saiz Produk Tidak Konsisten: Bahan besar (slabby or elongated) from a worn or poorly designed chamber reduces downstream cone crusher efficiency by 1520%, increasing recirculating loads and energy consumption.
3. Kos Pakai Tinggi: Standard manganese liners in highabrasion applications (mis., granit, basalt) often require replacement every 46 minggu, driving up consumables spend and labor costs for changeouts.

Bagaimana anda boleh mencapai konsisten 68 inch minus product while maximizing uptime and minimizing cost per ton? The answer lies in a crusher engineered for sustained, highforce compression.

Gambaran Keseluruhan Produk: The JC5000 HeavyDuty Primary Jaw Crusher

The JC5000 is a singletoggle, overhead eccentric jaw crusher designed for the most demanding primary and secondary reduction applications in hard rock mining and largescale aggregate production.

Aliran Kerja Operasi:
1. Suapan: Runofmine (ROM) material up to 30 inci (762mm) is fed via a vibrating grizzly feeder into the crusher's large, flared feed opening.
2. Mampatan: Aci sipi berputar, driving the movable jaw plate in an elliptical path against the stationary jaw plate.
3. Menghancurkan: Material is crushed through a combination of compression and shearing forces as it moves down the Vshaped chamber.
4. Pelepasan: Reduced material exits through the adjustable closed side setting (CSS) di bahagian bawah bilik.
5. Takeaway: The crushed product is conveyed to a surge pile or directly to the secondary crushing stage.

Skop Permohonan & Batasan:

• Skop: Ideal for primary crushing of hard and abrasive rock (granit, basalt, kuarzit), bijih (Tembaga, emas, besi), dan konkrit kitar semula.
• Batasan: Tidak sesuai untuk melekit, clayrich materials that can plug the chamber. Maximum feed size is strictly limited by the gape opening.

Soalan Lazim

1. Can the JC5000 handle feed material with high moisture or clay content?
Tidak. The JC5000 is designed for dry to moderately moist, freeflowing material. High clay content can cause plugging in the crushing chamber. For sticky materials, a grizzly feeder with a bypass chute is recommended.

2. What is the expected lifespan of the main frame?
The main frame is constructed from stressrelieved, heavyduty steel plate. Di bawah keadaan operasi biasa, the frame is designed for a 20+ hayat perkhidmatan tahun. FEA analysis confirms it can withstand 200% of the rated crushing load.

3. Bagaimanakah sistem CSS hidraulik meningkatkan kecekapan operasi?
It eliminates manual shim adjustments. Your operators can change the product size from a control panel in under 5 minit, allowing for rapid response to changes in feed material or market demand for different aggregate sizes.

4. What is the lead time for replacement manganese liners?
Standard liners are typically in stock and can be shipped within 57 hari perniagaan. Custom profile liners require a 46 masa memimpin minggu. We recommend keeping a spare set on site to minimize downtime during changeouts.

5. Can the JC5000 be integrated with an existing plant control system?
ya. The crusher is equipped with standard I/O for remote start/stop, motor current monitoring, and bearing temperature sensors. It can be integrated with any major PLC platform (AllenBradley, Siemens, dll.) via Modbus or Profibus.

6. What is the power requirement for the JC5000?
The recommended motor is 200250 Hp (150185 kw) di 1800 Rpm. A Vbelt drive is standard. The electrical supply should be 480V, 3fasa, 60Hz (or equivalent international standard).

7. What financing options are available for a JC5000 purchase?
We offer leasetoown programs with terms from 36 ke 60 bulan, as well as traditional equipment loans. A tradein evaluation for your existing crusher can also be arranged to reduce your upfront capital expenditure.
