Peterson 4700D Horizontal Grinder

Overview

The 4700D is a wheeled horizontal grinder designed for high-volume producers with very demanding end-product specifications.

The 4700D is powered by a Tier IV Caterpillar C18 engine rated at 755 horsepower (563 kW). A Tier II, 765 horsepower (570 kW) engine is also available.

It features Peterson’s Adaptive Control System, which controls all components of the feed system to optimize output. This system senses variations in the engine load and adapts the operating parameters to produce the maximum amount of material at all times.

Applications

Orchard Clearout

Commercial orchards are cleared on a rotating cycle to remove lower producing or unhealthy deciduous fruit, citrus and nut trees or to replace them with a more valuable crop. New, higher-producing trees are replanted so the cycle can start again.

Asphalt Shingle Recycling

Asphalt shingle grinding is the process of making recycled asphalt shingles (RAS). RAS is produced by grinding asphalt roofing shingles to a small spec, generally under 3/8” to salvage the valuable asphalt and sand.

Organic Recycling

Green waste recycling is fresh or biodegradable waste material including grass, leaves, plants and tree trimmings that can be diverted from landfills for recycling. This method is best used to produce compost for use on gardens, lawns, erosion control projects and agricultural crops.

Land Clearing

Land clearing generally consists of trees, limbs and roots cleared from forested or partially forested land that will be used for a new purpose including farming, commercial development or right-of-ways.

Salvage Timber

Salvage logging is the removal of dead or damaged trees from forestlands that have been damaged by wildfire, harsh winds, flood, disease, infestation of insects and other natural causes.
