Horizontal Shaft Impactor

American Pulverizer Horizontal Shaft Impactors are primary and secondary impact crushers. They are available in 20 sizes with rotor dimensions from 12" to 72" and feed openings from 7½" x 12½" to 42" x 84". Throughput capacity can vary from 25 TPH to 1000 TPH depending on the crusher model and material characteristics. They also accept feed sizes up to 24" and generate a cubical product from 0 to 4".

Electric or diesel motors are used to drive our impactors. Rotor speeds vary from 300 to 900 RPM depending on the model of the machine and gradation requirements. Due to the true impact principle, 3-Stage impact mechanism and slow rotor speed, it is possible to operate the crusher with minimum wear and power consumption. No grates are used.

The American Impactor is resistant to uncrushables and plugging. All wear parts can be easily replaced from the side or top. All wear parts can be easily replaced from the side or top by opening the housing cover with the hydraulic system.

Product gradation can be easily changed by hydraulically adjusting the gap between blow bars and impact plates, even while crushing.

American Pulverizer owns the rights to manufacture and service the Torgerson line of single rotor impactors and parts. Torgerson machines include the AAX, AX, BX, CX, DX, and E models.
