Compact Impact Crushers Pulverize a Variety of Worksite Materials

The impact crushers we offer at our locations around Alabama are available through both Screen Machine Industries and IROCK. The pulverizing mechanism located within the chamber of each machine grinds down all types of materials and is especially effective in crushing hard rock materials.

The two models we provide for Screen Machine Industries (5256T and 4043T) are specifically designed for concrete and asphalt surfaces. The Remote Crusher Relief System allows for both machines to continually clear out the chamber of debris without stopping mid-crush, which drastically reduces the amount of time covering a job site. The 4043TR model includes a radial arm that can be positioned off to the side to create an additional pile.

IROCK allows us to offer wheeled, portable planted crushers (RDS models) as well as the Magnum crusher. The two portable crushers come standard with two decks each which allow for quicker production time. The Magnum crusher has one power source and a hopper that is able to be torn down and set-up in just a matter of minutes.

Impact crushers involve the use of impact rather than pressure to crush material. The material is fed into a cavity with openings on the bottom, end, or side to allow crushed material to exit the crusher. Our horizontal single shaft machines break material by impacting it with hammers (blow bars) that are fixed on the outer edge of a spinning rotor. The rotor has two (2) active “blow” bars and two (2) dummy bars. The active bars throw the material into the stationary “anvils” to create the impact crushing process and dummy bars are primarily for rotor balance. When wear occurs on the active bars and they can be rotated in the field to prolong bar life.

Impact Crushers have a Reduction Ratio of approximately 15:1. An example of this ratio of reduction would be that a 30” input particle can be reduced to approximately a 2” discharge particle. Impact crushers tend to produce more “fines” that other types of crushers and are best suited to produce a “dense graded” type product or to provide feed material to a screening unit where the amount of fine product is important. Wear rates for an Impactor are increased when the feed material increase in abrasiveness.

 Normal Closed Side Setting – CSS (distance between the active bar and the lower anvil) normally run in the 1” range and can go up to 3”. The CSS is adjustable in the field. A top size material specification cannot be guaranteed from an impactor. Normally 60% to 70% of the discharge material will be smaller than the CSS. If a guaranteed top size is required for a specific application, the crusher can be paired with a Spyder screening unit or a “recirculating” impactor can be used.

An additional benefit to many of our pieces is the portable feature. IROCK and Screen Machine Industries both offer machines which are meant to be used all over your construction site. Instead of being built and having trucks bring in loads of material, the crusher itself can be moved around to reach all areas of your site.

It's hard to find machinery to help you in your small construction sites, but Thompson Tractor is here to make the process of finding the right equipment easy. We offer a live chat on our website to get you the direct help and information you need, as well as consultations over the phone.
