1. PEMBUKAAN PAINPOINT DRIVEN

Kos operasi yang meningkat dan masa henti yang tidak menentu menghakis margin pengeluaran agregat anda? Untuk pengurus loji dan kontraktor kejuruteraan, cabaran teras dalam penghancuran primer selalunya tertumpu pada tiga bidang kritikal:

Masa Henti Tidak Berjadual: Kegagalan galas, unexpected wear part changes, and mechanical breakdowns halt your entire downstream process. Every hour of lost production can represent thousands in lost revenue and idle labor costs.
Inconsistent Throughput & Bentuk produk: Kekerasan dan saiz bahan suapan yang berubah-ubah boleh menyebabkan penyusuan tercekik atau peronggaan, leading to suboptimal tonnage and poor particle shape that affects secondary crushing efficiency and final product value.
SkyHigh Maintenance Complexity & Kos: Traditional designs require extensive manual adjustment, frequent lubrication interventions, and lengthy procedures for wear part replacement, demanding significant skilled labor hours.

How do you select a primary stone crusher plant that delivers not just raw power, but predictable performance, simplified maintenance, and a demonstrable return on investment? The solution requires a focus on engineered reliability and operational intelligence.

2. GAMBARAN KESELURUHAN PRODUK: PRIMARY JAW CRUSHER STATION

This product description details our heavyduty mobile primary jaw crusher plant, engineered for the first stage of rock reduction in quarrying, perlombongan, dan aplikasi kitar semula perobohan. The plant is designed as a selfcontained crushing station for processing hard abrasive materials like granite, basalt, dan konkrit kitar semula.

Aliran Kerja Operasi:
1. Suapan: Dump trucks or wheel loaders deposit runofquarry material (sehingga saiz suapan yang ditentukan) into the vibrating grizzly feeder (VGFF VGF).
2. PraSkrin & Menghancurkan: The VGF removes fines from the feed stream via a bypass chute while directing oversize material evenly into the robust jaw crusher cavity.
3. Pengurangan utama: The jaw crusher utilizes compressive force to break large rocks into smaller fragments (typically 150mm 200mm).
4. Pelepasan: Crushed material is discharged onto the main product conveyor for transport to the next stage or a stockpile.

Skop Permohonan & Batasan:
Skop: Ideal untuk penghancuran utama batu keras (Kekuatan Mampatan > 250 MPa), batu kuari yang diletupkan, construction demolition waste, dan kerikil sungai.
Batasan: Tidak sesuai untuk melekit, bahan kaya tanah liat tanpa prapemprosesan. Maximum feed size is fixed by crusher inlet dimensions; oversize rock requires preblasting or breaking.
