Cedar Rapids 3042 Jaw Crusher: An Overview for Buyers
The search for "Cedar Rapids 3042 for sale" typically refers to the sought-after Cedar Rapids 3042 Jaw Crusher, a robust piece of aggregate processing equipment. This machine, a staple in many quarries, recycling operations, and mining sites, represents a specific model from the historic Cedar Rapids line (now often associated with Terex® MPS). This article provides a factual overview of the crusher's specifications, common considerations when purchasing a used unit, and practical insights based on its known design and industry application.
A primary consideration for buyers is understanding where the 3042 model fits among similar jaw crushers. Its designation, "30" x "42", indicates the feed opening size in inches (30 inches wide by 42 inches across), which classifies it as a medium-to-large primary crusher. Below is a comparison based on common industry specifications for this model lineage versus other typical sizes.
| Feature | Cedar Rapids 3042 Jaw Crusher | Smaller Model (e.g., 2036) | Larger Model (e.g., 3648) |
|---|---|---|---|
| Feed Opening | 30" x 42" (762mm x 1067mm) | 20" x 36" (508mm x 914mm) | 36" x 48" (914mm x 1219mm) |
| Typical Max Feed Size | ~24 - 26 inches | ~16 - 18 inches | ~32 - 34 inches |
| *Approximate Capacity (TPH)** | 130 - 280 | 75 - 140 | 250 - 500+ |
| Primary Application | Primary crushing of shot rock, river gravel, demolition concrete. | Primary/Secondary for smaller operations or recycling. | High-volume primary crushing in large quarries. |
| Power Requirement | Typically a 150-200 HP electric motor. | Typically a 75-125 HP motor. | Typically a 250-350+ HP motor. |
*Capacity varies significantly based on material type, hardness, feed gradation, and crusher settings.
Real-World Application Case: Base Aggregate Production
A documented example of a Cedar Rapids 3042 in operation can be found in mid-sized aggregate producers. For instance, a quarry in the Midwest historically used a Cedar Rapids 3042 as its primary crusher to process shot limestone from a nearby blast site. The plant's flow was designed to feed shot rock directly into the 3042's vibrating grizzly feeder, which would bypass sub-8-inch material. The jaw crusher, set with a closed side setting (CSS) of approximately 4-5 inches, would reduce the oversized rock to a manageable size for conveyance to secondary cone crushers. Its reliability and straightforward mechanical design made it suitable for this demanding daily duty, forming the critical first stage in producing road base material (#2 coarse aggregate) and crusher run stone.
Frequently Asked Questions (FAQ)
Q1: What should I inspect when looking at a used Cedar Rapids 3042 for sale?
Key inspection points include: the condition of the jaw dies (cheek plates and moveable/stationary dies), the integrity of the jaw die wedges and seats, the toggle plate and seats for cracks or wear, the pitman shaft and bearings for play or damage, and the condition of the frame—especially around high-stress weld points. Request documentation of any recent repairs or rebuilds.
Q2: Are parts still available for these older Cedar Rapids machines?
Yes, support remains strong. While original OEM parts from Cedar Rapids/TEREX are available through authorized distributors, there is also an extensive aftermarket network that manufactures high-quality replacement parts like dies, toggle plates, and bearings specifically for these models.
Q3: What is the typical weight and setup requirement for this crusher?
A Cedar Rapids 3042 jaw crusher assembly (including base frame but excluding feeder or discharge conveyor) typically weighs between 48,000 to 55 ,000 lbs. It requires a substantial foundation and is often mounted on heavy-duty steel support frames or concrete piers in permanent installations.
Q4: Can it be used for recycling concrete and asphalt?
Absolutely. The 30 42 is commonly used in concrete/asphalt recycling yards as a primary crusher. Its robust construction handles reinforced concrete well. It is often equipped with an electromagnetic separator over the discharge conveyor to remove rebar and other ferrous metals post-crushing.
Q5: What are common drive configurations?
The most common configuration is an electric motor driving V-belts connected to the crusher's flywheel drive sheave. Some units may have been configured with diesel engine drives or hydraulic drives for portable or temporary setups.
