Built for Mulch Production

Mulch producers running RotoChopper machines know that particle size consistency directly affects product quality. Colored mulch especially requires uniform particles. Dye takes unevenly on a mix of fine and coarse material, and customers notice. A screen that holds its spec keeps your product consistent from load to load.

GrinderCrusherScreen builds RotoChopper screens to the hole size and steel grade that fits your production spec. If you need a specific particle size, tell us what you are producing and we will recommend the right screen configuration.

Frequently Asked Questions

How do I order a screen for my RotoChopper?

Call 770-433-2670 with your model number. If we have the drawing on file, we quote it from there. If not, provide the panel measurements and we build to your dimensions. We confirm the fit before we cut steel.

What hole size should I run for mulch production on a RotoChopper?

For standard bulk mulch, a 2" to 2-1/2" hole is the typical starting point. For fine bagged mulch, 1" to 1-1/2" gets you a finer particle. Your machine horsepower and feed rate also affect final output. See the Grinder Screen Size Guide for a full breakdown by application, or call 770-433-2670 and describe your target product.

How does screen condition affect colored mulch quality?

A worn screen produces inconsistent particle size across the same batch. Uneven particles take dye unevenly. Some pieces come out darker, others lighter.

That inconsistency shows up in the finished product and in customer complaints. Replace the screen before particle size spreads beyond your product spec. Do not wait for a full failure.
