Electric motors for size reduction applications

We build electric motors, shaft mount reducers, and accessories for rugged industry solutions like the processing of aggregate. We offer custom designed control and drive panels to support aggregate and crushing applications.

Advanced Design Rock Crusher Motors

Our rock crusher motor can operate with several types of rock crushers. We use FC200 density cast iron for the motor, roller bearings on the drive-in for belt applications, and a circlip on the opposite drive-in of the motor that allows the motor to be used for vertical shaft applications, such as VSI crushers. In large horsepower motors, we use 4140 steel shafts. We also radius cut those shafts to make them stronger than standard cuts. These motors come in stock through 600 horsepower (compared to an average of 150-500 horsepower at 1200 rpm). Unlike many other manufacturers, we stock 900 rpm motors for users with crushers that run at lower speeds. To help adjust mounting positions, we also provide motor slide bases.

The Complete Rock Crushing Package

We have also developed a Heavy Duty Solid State Reduced Voltage Starter (aka: Advanced Design Rock Crusher Starter) that’s specifically designed for harsh environments, in a NEMA enclosure.  A unique feature it offers is a full horsepower, start-rated bypass contactor.  It also has a selector switch for soft start or across the line capability. Again, this product also comes in stock through 600 horsepower. This unit is specifically built and designed for rock crushing applications.

Variable Frequency Drive Packages

We also build variable frequency drive packages that can be used on crushing or feeder applications – available through 500 horsepower.  They are complete, packaged drives (part of the heavy duty series of our closed drive packages) that allows for variable speed changes for rock crushers, feeders or conveyors.

Other Size Reduction Applications

Our size reduction motors aren’t limited to crushing rocks. The diversity of our products also aid in several other size reduction applications: cement, pulp & paper, the wood industry, and even food industries for the rolling out of items like pasta on large roll mills.

Why WorldWide ?

We hold a rich inventory of large horsepower motors, gear reducers and enclosed starters and drives that are readily available. Our aggregate solutions offer unique features and benefits that not every manufacturer offers in their product line. Also, to reassure your end users who will apply our products in harsh conditions, our warranties exceed industry standards (in many cases by as much as 50%).  As always, we offer support that is unsurpassed in the industry, along with 24/7 emergency service.
