Vertical Shaft Impactor

As natural sand deposits are depleting, the demand for man-made sand has increased. Our impact crushers are proven to be the most efficient method for size reduction to manufacture sand. Prior to the REMco SandMax, a wide range of crusher types had been applied to the task with limited success. The challenge of creating a quality product, in specifications, with high durability, cubical particle shape, and with the desired F.M. (fineness modulus) has caused many crusher failures.

High-strength sand comes from hard rock, and hard rock is where the REMco SandMax beats all other crushing machines. For versatility of use, net tons of product, total run cost, ease of installation, smoothness of operation, reliability, and hassle-free performance, the REMco SandMax is superior to all others.

Producing quality specification sand requires more than a crusher. It requires knowledge, a well-designed material processing circuit, specialized rotors, and the willingness to understand that sand production is more than rock crushing. At REMco, we can teach you how to make your sand.

REMco VSI SandMax crushers are fully autogenous vertical shaft impact crushers designed to operate as third or fourth stage crushers in the processing of all types of rock, ores, and minerals. SandMax crushers can be operated in either open-circuit or closed-circuit. Closed-circuit operation is recommended to achieve the lowest net operating cost and the highest production of any given size below 1/2″ (13 mm).

For less abrasive stones and minerals, the Swing Top / Anvil Ring Vertical Shaft Impact Crusher, or ST/AR VSI, is the way to go. They’re a variation of the REMco SandMax and RockMax series, but specialized.

These machines feature the same heavy-duty design and components, as well as our new bearing cartridge and main shaft design, but with the addition of our innovative, reversible anvil design that lets you use the most of the wear iron in the anvil. There are several anvil shapes, each suitable for a broad range of applications. This feature provides maximum crushing efficiency when the anvils are new and concentrates the wear on half of the anvil face. This raises the percent of wear iron in use and extends the life of the anvil and the efficiency of the crusher.

By simply rotating the anvil you are provided with an entirely new crushing face on the same anvil, thus allowing you to maintain maximum crushing efficiency during the entire life of the anvil as opposed to just when it’s brand new. This innovation also reduces scrap loss. REMco ST/ARs are incredibly versatile too. They can easily be converted from the rock-on-anvil crusher to a fully autogenous, rock-on-rock chamber.

REMco ST/AR VSI crushers are rock-on-anvil vertical shaft crushing machines designed to operate as second, third or fourth stage crushers for processing soft to medium/hard rocks, ores or minerals that contain less than 15% abrasives (silica, alumina, and iron). Maximum feed size is 6” (150 mm) and product sizes can be from 1 1/2” (40 mm) to minus 6 mm.
