VEVOR Hammer Crusher, 3KW 220V Model
- Brand: VEVOR
- Crushes multiple rock types and glass bottles
- 3KW pure copper motor at 1740 RPM
- Capacity: 400 to 600 kg/h
- Includes three replaceable screens: 0.12 in, 0.24 in, 0.4 in
Best for: Builders and field technicians handling medium-hard rocks, bricks, limestone, and glass. This unit excels when high throughput and precise sizing are needed. Limitations: Heavier and requires a 220V power source, which may limit mobile setups.
VEVOR Hammer Crusher, 2.5KW Model
- Brand: VEVOR
- Suitable for rocks under 2.17 inches and moisture under 20%
- 2.5KW copper motor at 1740 RPM
- Output capacity: 100 to 200 kg/h
- Three mesh screens: 0.12 in, 0.24 in, 0.4 in
Best for: Small workshops or solo pros performing lighter-duty rock processing or glass crushing. Better for: tighter spaces where load is lower and power supply is stable. Caution: Throughput is lower than the 3KW model, so plan for smaller batches.
Super Heavy Duty Rock Crusher Replacement Screens
- Brand: K&M Krushers
- LOT OF 3 screens
- .045 inch thick perforated steel
- Works with compatible hammer or jaw crushers
Best for: Buyers needing quick, compatible replacement screens to maintain throughput. Choose this if you already own a primary crusher and want consistent mesh sizing. Limitation: These are screens, not crushers, so you still need a separate crushing unit.
Yoursme Cast Iron Mortar and Pestle Large Rock-Ore Crusher
- Brand: Yoursme
- Large 8 Pound / 3.6 KG mortar and pestle
- Use for field ore testing and gold prospecting
- Design supports crushing and grinding; no power required
Best for: Prospectors and hobbyists needing hands-on rock crushing without electricity or for preliminary ore testing. Limitation: Manual operation is more labor-intensive than powered crushers.
VEVOR Jaw Crusher Machine, 2.2KW
- Brand: VEVOR
- Crushes rocks under 3.93 inches
- 2.2KW copper motor at 1740 RPM
- Output range: 480 to 1800 kg/h with adjustable discharge (0.2 to 1.65 inch)
- Suitable for calcite, quartz, shale, basalt, and more
Best for: Projects needing robust, high-throughput rock reduction with adjustable output size. Better for: applications requiring larger feed sizes and efficient material handling. Caution: Output sizing requires careful setting to avoid oversized material.
Buying Guide
- What material will you process? For rocks, bricks, glass, and limestone, a hammer crusher with multiple screens offers flexible sizing. For harder, chunky rocks, a jaw crusher provides stronger feeding capability.
- How much throughput do you need? If you work in batches, a unit delivering 100–600 kg/h covers most small to mid-scale jobs. For continuous operation, prefer higher-capacity models with reliable motors.
- Power availability matters. 220V models (3KW, 2.5KW, 2.2KW) require a stable power source. Plan for proper electrical setup and ventilation in workspace.
- Screening and sizing. Look for interchangeable screens (0.12 in, 0.24 in, 0.4 in or similar) to control product granularity and reduce secondary processing.
- Portability and footprint. Heavy units offer field durability but require transport, while compact units fit small shops or mobile setups. Consider wheel kits or handles if you move equipment often.
- Durability and materials. Cast-iron mortars deliver hands-on testing and are useful for field assays; powered crushers rely on robust housings and copper motors for longevity.
FAQ
- What is a “3 point rock crusher”?
In this context, it refers to compact, power-equipped crushers designed for field or workshop use with multiple output options and, in some cases, a modular screening approach. - Which crusher suits glass crushing best?
Hammer crushers with interchangeable screens handle glass and bottles efficiently, especially when paired with 0.12–0.4 inch screens. - Do these units require special maintenance?
Regular inspection of motors, belts, and screen integrity is advised; ensure proper lubrication of moving parts and clean the housing after use. - Can I use these for field ore testing?
Yes, especially mortar-and-pestle tools and manual testing kits. For larger ore samples, powered crushers provide faster reduction before panning or assay steps. - Is replacement screening readily available?
Yes, third-party and manufacturer replacement screens are commonly offered; verify compatibility with your exact model before purchasing. - Which model offers the best balance of size and throughput?
The 3KW hammer crusher provides higher throughput and larger feed capacity, while the 2.5KW model is more compact for tight spaces.
