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

Introdução
No exigente mundo do processamento mineral, produção agregada, e reciclagem de materiais de construção, jaw crushers remain the undisputed workhorses for primary and intermediate size reduction. Entre a diversificada gama de britadores disponíveis, 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., Ltda. (now part of the global group but retaining the Shanbao brand legacy), this crusher embodies decades of engineering expertise focused on performance, durabilidade, and operational economy.

This article delves into the technical specifications, design features, operational principles, typical applications, vantagens, and essential considerations surrounding the Spek/Shanbao PEX-250×1000 jaw crusher.

Especificações principais & Dimensões
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. Tamanho da abertura de alimentação: 250 milímetros (Largura) x 1000 milímetros (Comprimento). This rectangular opening dictates the maximum lump size it can accept.
2. Tamanho máximo de alimentação: Typically up to 210 milímetros (aprox.. 80-85% of feed opening width is a common rule of thumb).

3. Faixa de abertura de descarga (CSS - Configuração lateral fechada): Adjustable within a range of approximately 25 mm para 60 milímetros (1" to ~2.4"). This setting directly controls the final product size distribution.
4. Capacidade: Highly dependent on feed material characteristics (dureza, densidade, umidade), distribuição de tamanho de alimentação, configuração de descarga, and crushing chamber design.
Typical Rated Capacity Range: 15 - 50 Toneladas por hora (TPH).
Exemplo: Crushing medium-hard limestone (~150 MPa compressive strength) with a CSS of 40mm might yield around 30-40 TPH.
5. Impulsione a potência: Equipped with an electric motor typically rated at 30 - 37 kW (40 - 50 HP).
6. Crusher Weight: Aproximadamente 6,500 kg (basic machine weight without motor or flywheel
