Products & Services

We can provide a wide range of custom machinery, both automated and non-automated.  Our designs are customized to our customers' needs and specifications.  We either do all or some of the fabricating & machining depending on the project and contract terms negotiated with each individual customer.  

Some examples of our designs are:
High Volume Custom Trommel
        •    Custom Conveyor
        •    Custom Roll Out Bucket

Our automated controls consists of:
        •    Electrical Design of UL508A Control Panels
        •    3 Phase Motors
        •    Process Sensors & Controls
        •    PLC Programming
        •    HMI Programming

Case Study - Trommel Project

We build custom trommels to meet specific needs: Different screen configurations, trommel diameter and length, as well as conveyor, chute, or push wall configurations.

In a recent project we designed and fabricated  a large 10' X 40' Electro-Hydraulically driven Trommel
 with 11 conveyors, used for the reduction of green waste.  This specific system has a through put of up to 120 tons of material per hour and is capable of producing up to 3 cuts of material, 2 different size fallout materials and the reduced green waste output.  The system is electrically automated using a Siemens Safety PLC with a rack of 17 I/O Modules & multiple sensors housed within a Stainless Steel, Nema 4, cabinet with a 19" touch screen mounted interface.   The Control Panel is designed to meet UL508A utilizing Siemens Automation Control Components.  

Trommel - Definition & Uses
A trommel or sometimes referred to as a rotary screen is a revolving screened cylinder used to separate materials by size: A mixed or coarse material is fed into the trommel at one end, the finer material drops through the holes or squares in the screen and is either conveyed or transported away, and the coarser material is discharged out the other end.  Examples: Separating dirt and debris from green waste (residential or forest undergrowth) to be used for landfill cover or topsoil and therefore, reducing the amount of material to grind or chip; separating the biodegradable fraction of mixed municipal waste; and, separating different sizes of crushed stone.  Another example and its benefits would be screening construction site debris into two fractions; saleable topsoil for farms, nurseries, and site-work, and rocks for aggregates or landscaping work.  This would allow the contractor to resell their waste instead of disposing of it at a cost.  This same principle applies to many different forms of material and industries.
