2. GAMBARAN KESELURUHAN PRODUK

This product line encompasses stationary and semistationary primary crushing plants engineered specifically for the volumetric reduction of runofmine (ROM) bijih besi. These plants are designed as integrated solutions, typically centered on highcapacity gyratory or jaw crushers.

Aliran Kerja Operasi:
1. Penerimaan ROM & PraSkrining: Dump trucks or haulers discharge material onto a heavyduty vibrating grizzly feeder, which removes subfines to bypass the crusher, reducing wear and increasing effective capacity.
2. Pengurangan saiz utama: The prescreened ore is fed into the primary crusher, which reduces lump ore from sizes often exceeding 1 meter down to a manageable 200250mm.
3. Pengendalian bahan & Stok: The crushed product is conveyed via heavyduty belt conveyors to a surge pile or directly to the next stage of secondary crushing or beneficiation.

Skop Permohonan: Ideal for greenfield mine development or the replacement of aging, inefficient primary stations in existing iron ore operations processing magnetite or hematite ores.

Batasan: These are fixed installations requiring concrete foundations and substantial initial civil works. For fully mobile inpit crushing requirements, mobile crushing stations should be evaluated separately.

8.SOALAN LAZIM

S1:What level of preparation is required at our site before installation?
A comprehensive geotechnical survey is required for foundation design.We provide detailed civil engineering drawings as part of the package.Customer responsibilities typically include preparing a level site,pouring foundations,and providing main power to the designated connection point.

Q2.How does this system handle sticky or highclaycontent iron ore?
We can integrate specific feeder designs( mis., stepped deck vibratory feeders)and recommend optional hydraulic clearing systems for the crusher chamber.This minimizes the risk of packingand bridging,a common issue with certain ore types.

Q3.What is the expected impact on our overall plant manpower requirements?
The system is designed for operation by one controller from the central control room.Maintenance requirements are streamlined,but do not typically reduce overall FTE count;they reallocate skilled labor from unplanned repair work towards planned predictive maintenance activities.

Q4.Are your components compatible with our existing secondary crushing circuit?
Yes.Conveyor speeds,crusher discharge settings,and overall capacity are engineered during the design phase to ensure seamless integrationwith your existing secondary,Tertiari,and screening stages.We require your current circuit specificationsfor interface planning.

Q5.What is your standard warranty,and what support do you offer postinstallation?
We providea24month warrantyon manufacturing defectsand major components.Field commissioningand operator trainingare included.Postwarranty,support rangesfrom parts supply onlyto fullservice contracts with guaranteed response timesand performance audits.
