Understanding the Jaw Plate for 60×100 Stone Crusher Units
In the realm of small-scale stone crushing and laboratory sampling, crushers with a jaw opening of 60×100 mm are a common fixture. The jaw plate, as the primary and most critical wear part of such machines, directly determines crushing efficiency, product granularity, and operational costs. This article provides a factual overview of the jaw plate for 60×100 jaw crushers, based on common industry specifications and practices..jpg)
Specifications and Dimensions
The designation “60×100” refers to the internal dimensions of the crushing chamber at the feed opening: approximately 60 mm in width and 100 mm in length. Consequently, the jaw plates (both fixed and movable) for this model are designed to match these dimensions. The exact physical size (length, width, thickness) and mounting hole patterns are model-specific. For instance, plates for a common laboratory crusher like the “Retsch BB 100” or similar Chinese-made “60×100 Jaw Crusher” are not universally interchangeable without verifying technical drawings.
Material Composition
Jaw plates are not generic steel items. They are consistently manufactured from high-wear-resistant materials to withstand abrasion and impact. The most common materials are:
- High Manganese Steel (Mn13, Mn18): This is the traditional standard. It work-hardens under impact, forming a hard surface layer while retaining a tough core. It is suitable for crushing hard and abrasive materials like granite, basalt, and quartz.
- High Chromium Cast Iron (Cr26): Offers superior abrasion resistance compared to standard manganese steel for highly abrasive materials but may be more brittle under severe impact.
- Alloy Steel: Sometimes used for specific applications requiring a balance of hardness and toughness.
The choice depends on the primary material being crushed.
Key Considerations for Purchase (Harga)
The price (harga) of a 60×100 jaw plate is influenced by several concrete factors:.jpg)
- Material Grade: Plates made from premium or specially formulated alloys command a higher price than standard manganese steel.
- Manufacturing Quality: Plates from foundries with strict quality control in heat treatment and casting processes ensure consistent hardness and microstructure, affecting both cost and service life.
- Supplier Type: Prices differ between original equipment manufacturers (OEM), third-party replacement part specialists, and local workshops.
- Market & Region: Logistics, import duties (if applicable), and local market competition influence final pricing.
Operational Importance
Using correctly specified and quality jaw plates is crucial because:
- Wear Life: Proper plates maximize operational time between changes, reducing downtime.
- Product Size: Worn or mismatched plates lead to inconsistent output size distribution.
- Crusher Health: Severely worn plates can reduce crushing efficiency and increase load on other components like bearings.
Maintenance Practice
Regular inspection is standard procedure. Plates should be rotated or replaced when wear reduces capacity or alters product size significantly. For double-toggle style 60×100 crushers, reversing or exchanging the fixed and movable plates can help utilize their full wear life evenly.
In summary, sourcing a jaw plate for a 60×100 stone crusher requires precise matching of physical dimensions and an informed selection of material grade based on the application. While cost is a factor, prioritizing proven quality from reliable suppliers typically offers better long-term value by ensuring higher crushing performance and extended service life for this essential consumable part
