The next generation of grinding power is here— mobile, efficient, and built for performance.

Astec Industries Inc. has introduced the all‑new Peterson 3710E Horizontal Grinder—a versatile, high‑performance solution built to tackle more jobs with greater mobility and efficiency than ever before.

The 3710E made its official debut at CONEXPO‑CON/AGG, where it was showcased as the newest evolution in Peterson’s proven grinder lineup, giving industry professionals an up‑close look at its next‑generation capabilities.

Designed with exceptional transportability, the 3710E moves easily between job sites without special permits or heavy‑haul trucking—delivering true high‑output performance without sacrificing mobility.

Powered by a 755‑horsepower Cat C18 engine, the 3710E provides increased processing capacity and an expanded screening area compared to previous models—all within a compact, efficient footprint engineered for maximum productivity.

The 3710E incorporates a suite of intelligent, performance‑enhancing innovations, including:
Industry‑Leading Grate Screening Area:

Combined with Peterson’s fast, easy‑change tooling system, operators can maximize throughput, reduce maintenance intervals, and boost overall profitability.
3‑Stage Grinding Process: A powerful up‑turn, three‑stage system that improves material fracturing and produces a more consistent, high‑quality product.

Impact Release System – Protecting Your Investment

The patented Astec Impact Release System uses air bags to deliver uniform grinding while absorbing impacts from contaminated feedstock. This feature—unique to Peterson grinders—helps safeguard critical components and reduce costly downtime.

Impact Cushion System – The Second Line of Defense

Urethane cushions and shear pins provide an additional layer of protection, helping prevent catastrophic mill damage in the event of severe impacts from foreign objects in the feedstock.

Maintenance has been redefined for speed, safety, and operator convenience.

The 3710E features:

A larger grate access door for better access to the inside of the machine
The streamlined one tool and grate change system to save time
A dedicated maintenance platform for safer and easier grate changes

Together, these enhancements deliver less downtime, more uptime, and a smarter, safer service experience.
Every element of the 3710E is engineered to work harder and last longer. Optional track widths and an available transport dolly ensure the machine can maneuver easily—even in tight or challenging job‑site conditions.
