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 (ТПХ) 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 (обычно до 1 meter or more in size) into various saleable aggregate products (например, основной материал, бетонный камень, асфальтовая крошка, песок) meeting specific size specifications at a rate of 400 tons every hour.

Stages & Components in the Schematic:

1. Потребление корма & Скальпинг:
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.
Вибрационный колосниковый питатель (ВГФФ ВГФ): Positioned below the hopper. Its primary functions are:
Регулируемый корм: Controls the rate of material entering the primary crusher, preventing overload.
Скальпинг: Удаляет мелкий материал (often undersized for primary crushing or soil) through its grizzly bars (typically spaced 4-6 дюймы / 100-150mm apart). This bypasses the primary crusher, повышение эффективности и снижение износа.
Защита: Removes very large, non-crushable debris ("бродячий металл" can be handled later).

2. Первичное дробление (Грубое сокращение):
Первичная дробилка: Receives scalped feed from the VGF. Для 400 TPH plant handling hard rock:

Курсор челюсти: Common choice for its robustness and ability to handle large feed sizes. A large jaw crusher (например, 60" х 89" or similar) with appropriate power is typical.
(Alternative: Вращающаяся дробилка): Offers higher capacity potential in a single unit but often has higher capital cost.
Функция: Reduces rock from ~1m down to roughly 6-8 дюймы (150-200мм).

3. Вторичное дробление & Screening Loop:
Конвейер (C1): Transports primary crushed material
