Pengenalan
Dalam dunia pemprosesan mineral yang menuntut, Pengeluaran agregat, and construction material recycling, jaw crushers remain the undisputed workhorses for primary and intermediate size reduction. Antara pelbagai penghancur yang ada, 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., LTD. (now part of the global group but retaining the Shanbao brand legacy), this crusher embodies decades of engineering expertise focused on performance, ketahanan, and operational economy.

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

Spesifikasi teras & Dimensi
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. Saiz pembukaan suapan: 250 mm (Lebar) x 1000 mm (Panjang). This rectangular opening dictates the maximum lump size it can accept.
2. Saiz suapan maksimum: Typically up to 210 mm (lebih kurang. 80-85% of feed opening width is a common rule of thumb).

3. Pelepasan pembukaan (CSS - Tetapan sampingan tertutup): Adjustable within a range of approximately 25 mm ke 60 mm (1" to ~2.4"). This setting directly controls the final product size distribution.
4. Kapasiti: Highly dependent on feed material characteristics (kekerasan, ketumpatan, kelembapan), Pengagihan saiz suapan, tetapan pelepasan, and crushing chamber design.
Typical Rated Capacity Range: 15 - 50 Tan per jam (Tph).
Contoh: Crushing medium-hard limestone (~150 MPa compressive strength) with a CSS of 40mm might yield around 30-40 Tph.
5. Kuasa memandu: Equipped with an electric motor typically rated at 30 - 37 kw (40 - 50 Hp).
6. Berat Penghancur: Kira -kira 6,500 kg (basic machine weight without motor or flywheel
