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 (typically up to 1 meter or more in size) into various saleable aggregate products (por exemplo, base material, concrete stone, asphalt chips, areia) meeting specific size specifications at a rate of 400 tons every hour.

Stages & Components in the Schematic:

1. Ingestão de ração & Escalpelamento:
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.
Alimentador Grizzly Vibratório (VGF VGF): Positioned below the hopper. Its primary functions are:
Regulated Feed: Controls the rate of material entering the primary crusher, preventing overload.
Escalpelamento: Removes fine material (often undersized for primary crushing or soil) through its grizzly bars (typically spaced 4-6 polegadas / 100-150mm apart). This bypasses the primary crusher, melhorando a eficiência e reduzindo o desgaste.
Proteção: Removes very large, non-crushable debris ("metal vagabundo" can be handled later).

2. Britagem Primária (Redução grosseira):
Triturador Primário: Receives scalped feed from the VGF. For a 400 TPH plant handling hard rock:

Maldito Mandíbula: Common choice for its robustness and ability to handle large feed sizes. A large jaw crusher (por exemplo, 60" x 89" or similar) with appropriate power is typical.
(Alternative: Triturador giratório): Offers higher capacity potential in a single unit but often has higher capital cost.
Função: Reduces rock from ~1m down to roughly 6-8 polegadas (150-200milímetros).

3. Britagem Secundária & Screening Loop:
Conveyor (C1): Transports primary crushed material
