The Engineered Flow: Schematic of a 400 TPH Rock Crushing Plant

Processing raw rock into precisely sized aggregates demands a sophisticated and efficient system. A schematic diagram for a 400-ton-per-hour (Tph) rock crushing plant provides the essential blueprint for understanding the sequence of operations, equipment interconnections, and material flow necessary to achieve this high-capacity output reliably. This article outlines the typical components and flow depicted in such a schematic.

Core Objective: Transform large blasted rock (biasanya sehingga 1 meter or more in size) into various saleable aggregate products (mis., Bahan asas, batu konkrit, kerepek asfalt, pasir) meeting specific size specifications at a rate of 400 tons every hour.

Peringkat & Components in the Schematic:

1. Pengambilan Suapan & Scalping:
Primary Dump Hopper: Large blasted rock is dumped by haul trucks into a robust, reinforced concrete or steel hopper. Capacity is designed to buffer surges in truck deliveries.
Getaran grizzly feeder (VGFF VGF): Positioned below the hopper. Fungsi utamanya adalah:
Suapan Terkawal: Controls the rate of material entering the primary crusher, preventing overload.
Scalping: Removes fine material (often undersized for primary crushing or soil) through its grizzly bars (typically spaced 4-6 inci / 100-150mm apart). This bypasses the primary crusher, meningkatkan kecekapan dan mengurangkan kehausan.
Perlindungan: Removes very large, non-crushable debris ("logam tramp" can be handled later).

2. Penghancuran utama (Pengurangan kasar):
Penghancur utama: Receives scalped feed from the VGF. Untuk a 400 TPH plant handling hard rock:

Kursus rahang: Common choice for its robustness and ability to handle large feed sizes. A large jaw crusher (mis., 60" x 89" atau serupa) with appropriate power is typical.
(Alternatif: Crusher Gyratory): Offers higher capacity potential in a single unit but often has higher capital cost.
Fungsi: Reduces rock from ~1m down to roughly 6-8 inci (150-200mm).

3. Menghancurkan sekunder & Gelung Saringan:
penghantar (C1): Transports primary crushed material
