TUJUANALAT PEMECAH BATU

Mendapatkan butiran batu pecah dalam jumlah danperbandingan yang direncanakan sesuai dengan gradasiyang dinginkan.

Peralatan yang digunakan dalam pemecah batu:1. Mesin bor batu dan bahan peledak batu2. Alat pemecah batu3. Alat pengangkut batu hasil ledakan4. Alat pemecah batu (stone crusher)5. Alat penyaring batu (sreen)6. Alat penyalur (feeder)

TAHAPANPELEDAKAN GUNUNG BATU

Gunung batu (quarry) dibor atau diledakan

TAHAPANLoading haul trucks

Loading haul trucks -- 50-ton truckbeing loaded by a shovel with a 7.5cubic yard capacity bucket

This machine uses a hydraulichammer to reduce oversized blastrock to a size that can beaccommodated by the primarycrusher. The machine is working ona bench.

TAHAPANLoading haul trucks

Haul trucks -- these diesel-powered trucks carry up to 50tons per load from the blast face to the primary crusher

TAHAPANLoading haul trucks

Haul roads are kept wet by water trucks to reduce dust.The water truck has also 'wet down' the broken rock('muck pile') to reduce dust.

TAHAPAN PERTAMACrushed stone (aggregates)

Primary crushingTrucks with a capacity of up to 50tons haul rock from where it isblasted and loaded by hydraulicshovels to the primary crusher. Forscale note man in the window of thecontrol room (left). .
