Чухал бүрэлдэхүүн хэсгүүд: Maintaining Your Allis-Chalmers 48" x 60" Эрүүлийн тусламж

The Allis-Chalmers 48” x 60” jaw crusher stands as a significant piece of industrial heritage and robust engineering prowess. Primarily deployed in demanding primary crushing applications within mining and aggregate operations for decades, these machines were built to handle massive feed sizes and deliver consistent throughput under heavy loads.

While production of new Allis-Chalmers crushers ceased long ago, countless units remain operational worldwide thanks to dedicated maintenance teams and a reliable supply of replacement parts. Understanding the critical wear components of this specific model (often designated as Model 4860 or similar) is paramount for maximizing uptime, аюулгүй байдлыг хангах, and optimizing crushing performance.

Хэсгүүд & Their Function:

1. Эрэл далмаг (Суурин & Хөдөлгөж болмоор): The heart of the crushing action.
Хөдөлгөөнгүй үхэх (Тогтмол эрүүний хавтан): Mounted directly onto the crusher frame.
Хөдөлгөөнт өлгүүр (Swing Jaw Plate): Mounted on the oscillating swing jaw.
Түүхий эд: Typically high-grade manganese steel (жишээ нь e., 14%, 18%, or even 22% Ээж) chosen for its exceptional work-hardening properties under impact.
Явж байна: Dies are reversible/turnable to maximize wear life; profile design (жишээ нь e., гөлгөр, Зэргийн) impacts product gradation; proper selection balances wear life against desired output shape.

2. Die Seats / Хацрын хавтан: Protect the main frame structure.

Located on both sides of the crushing chamber between the frame side liners and the outer edges of the jaw dies.
Directly absorb impact from feed material and protect the crusher body from excessive wear.

3. Хурцадмал саваа & Spring Assemblies: Critical for maintaining nip angle and absorbing shock loads.
Хурцадмал саваа: Heavy-duty rods that run through large coil springs at the rear of the swing jaw assembly.
Spring Assemblies: Provide constant pressure on the toggle block/seats to maintain proper die positioning during operation and allow temporary relief for uncrushables ("эр төмөрц"). Regular inspection for cracks or loss of tension is vital.

4. Toggle Plates & Суудал / Toggle Blocks:
The toggle plate transmits force from the swing jaw motion to the fixed rear frame point via toggle seats
