1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Managing a Chinese stone quarry crushing plant presents distinct operational and financial pressures. Сталкиваетесь ли вы с этими общими проблемами?
Незапланированный простой: Frequent mechanical failures in crushers or conveyors halt your entire production line, потери производительности и простоя труда обходятся тысячами в час.
Непоследовательная градация продукта: Колебания конечного размера заполнителя приводят к браковке продукта., forcing reprocessing and damaging your reputation with asphalt and concrete batch plant customers.
Высокий расход изнашиваемых деталей: Абразивная природа гранита, базальт, или известняк быстро разрушает вкладыши, челюсти, и ударные стержни, creating unsustainable costs for spare parts inventory and replacement labor.
Энергетическая неэффективность: Старше, singlestage or poorly configured crushing circuits consume excessive power per ton of processed material, снижение прибыли.
Соответствие требованиям по пыли и шуму: Increasingly stringent environmental regulations require significant investment in control systems to avoid fines and operational shutdowns.

How do you transform these cost centers into controlled variables? The solution lies in specifying a modern, integrated Chinese Stone Quarry Crushing Plant designed for total cost of ownership.

2. ОБЗОР ПРОДУКТА

Современный Chinese Stone Quarry Crushing Plant is a stationary or semimobile hard rock processing system engineered to transform blasted quarry feed (обычно 0750 мм) into precisely graded commercial aggregates (например, 05мм, 510мм, 1020мм). It is not a single machine but a synchronized circuit of primary, вторичный, and tertiary crushing stages with integrated screening and material handling.

Операционный рабочий процесс:
1. Первичное сокращение: Dump trucks feed blasted rock into a primary jaw crusher for initial size reduction.
2. Предварительный скрининг & Вторичное дробление: A vibrating grizzly feeder removes fines before coarse material is conveyed to a secondary cone crusher for further reduction.
3. ClosedCircuit Tertiary Crushing & Скрининг: Затем материал проверяется; oversize is recirculated through a tertiary cone or impact crusher in a closed loop to achieve precise final gradation.
4. Накопление запасов: Заполнители нужного размера транспортируются на определенные склады с помощью радиальных штабелеров..

Область применения & Ограничения:
Объем: Optimized for mediumtohigh volume production (150800 ТПХ) of construction aggregates from hard rock (прочность на сжатие >150МПа). Ideal for largescale infrastructure projects requiring consistent, highspecification material.
Ограничения: Not suitable for soft minerals or sandonly production without significant circuit modification. Requires substantial capital investment and prepared site infrastructure (фонды, power supply).
