Frequently Asked Questions
If I am trying to reduce my fines in a limestone quarry, should I use a Jaw Crusher instead of a Primary Impactor?
While it is true the Jaw Crusher will create less fines (say, minus 3/16”), it also creates more plus 1-1/2” material to be crushed downstream at the secondary and tertiary stages. Regardless of the type of crushers used downstream, the amount of fines generated in those closed circuit operations will actually be greater than any increase caused by a primary impactor.
How do the power consumption figures compare between Primary Impactors like the MaxCap and the VersaCap?
Since one employs an expansion chamber over the rotor and the other doesn’t, the MaxCap will perform at ½ hp per ton, while the VersaCap averages ¾ hp per ton. Electric motors will only draw as much power as the crusher needs. However, the theoretical difference in a 500,000-ton quarry or mine is about 90,000 kW/hours. That reflects only the primary crusher, not the added power it takes downstream to also recirculate 30% more rock through the secondary circuit.
Why do I see so many Impact Crushers in concrete recycling when the material is 100% abrasive?
Unlike sedimentary stone, e.g. limestone or sandstone, weathered concrete is very soft and friable. Most concrete pavement is less than 1,500 psi and pre-broken into slabs 2’ to 3’ square. Due to the friability, they shatter quickly into particles 3” and smaller on the initial pass through the impactor. The hammer wear life tends to be far shorter due to the abrasion, but recirculating loads are minimal for base material. In the case of a mobile contractor, single crusher systems are far more economical when relocating on a regular basis.
What is the main difference between the VersaCap P-Series and the R-series? Are they both primary impactors?
Yes, they are both primary impactors. In fact, the only real difference is the rotor assembly. The VersaCap P-Series is a primary impactor that accepts 30” boulders in quarried stone, and generates a nominal 6” minus. The VersaCap R-Series uses the same housing, but the rotor is designed specifically for large, highly-friable materials like concrete rubble. In the case of recycling concrete, the R-Series rotor is lighter in weight for portability, and the hammers are thinner, reducing the cost of spent hammers.
Under what circumstances should I consider automation for adjusting an Impactor?
The MaxCap Primary Impactor comes standard with fingertip control. While not fully automated, it is designed to integrate into any programmable logic controller based system. As for the other impactors, the vast majority of operations will be fine with a simple shim adjustment, which requires no automation. However, the semi-automatic system on the VersaCap and NGS Impactors essentially requires only an electrical control over the hydraulic system, which would be running during operation. Once you find the right setting, and plan to stay consistent, you can add shims, and shut off the hydraulic power unit. If you are anticipating the need to change settings on a regular basis, the full automation system with PLC and touch screen is available and capable of being integrated.
