The Spek Jaw Crusher Shanbao PEX-250×1000: Engineered for Efficient Intermediate Crushing

Введение
В требовательном мире переработки полезных ископаемых, совокупное производство, and construction material recycling, jaw crushers remain the undisputed workhorses for primary and intermediate size reduction. Среди разнообразного ассортимента доступных дробилок, the Shanbao PEX-250×1000 (commonly referred to as the "Spek 250x1000" in some regions/catalogs) stands out as a robust and reliable solution specifically engineered for efficient secondary or tertiary crushing applications. As a key product from Shanghai Jianshe Luqiao Machinery Co., ООО. (now part of the global group but retaining the Shanbao brand legacy), this crusher embodies decades of engineering expertise focused on performance, долговечность, and operational economy.

This article delves into the technical specifications, design features, принципы работы, типичные приложения, преимущества, and essential considerations surrounding the Spek/Shanbao PEX-250×1000 jaw crusher.

Основные характеристики & Размеры
Understanding the fundamental metrics of any crusher is paramount for selection and integration into a processing circuit. The PEX-250×1000's defining characteristics are:

1. Размер загрузочного отверстия: 250 мм (Ширина) х 1000 мм (Длина). This rectangular opening dictates the maximum lump size it can accept.
2. Максимальный размер подачи: Typically up to 210 мм (приблизительно. 80-85% of feed opening width is a common rule of thumb).

3. Диапазон разгрузочного отверстия (CSS - Закрытая боковая установка): Adjustable within a range of approximately 25 мм до 60 мм (1" to ~2.4"). This setting directly controls the final product size distribution.
4. Емкость: Highly dependent on feed material characteristics (твердость, плотность, влага), распределение корма по размерам, установка разряда, and crushing chamber design.
Typical Rated Capacity Range: 15 - 50 Тонн в час (ТПХ).
Пример: Crushing medium-hard limestone (~150 MPa compressive strength) with a CSS of 40mm might yield around 30-40 ТПХ.
5. Мощность привода: Equipped with an electric motor typically rated at 30 - 37 кВт (40 - 50 HP).
6. Вес дробилки: Примерно 6,500 кг (basic machine weight without motor or flywheel
