What GPM does a skid steer screening bucket need?

Most skid steer screening buckets require 15 to 30 GPM of auxiliary hydraulic flow. Standard-flow skid steers typically produce 15 to 22 GPM, which is adequate for many screening buckets. High-flow buckets that require 25+ GPM need a high-flow skid steer or a hydraulic upgrade. Always check the bucket manufacturer's specifications against your machine's auxiliary flow rating before purchasing.

Can I use a screening bucket on a Bobcat?

Yes. Most screening buckets use a universal skid steer quick-attach plate that fits Bobcat and other major skid steer brands. The key factor is not the brand of skid steer but the machine's auxiliary hydraulic flow and lift capacity. Check your specific Bobcat model's specs to make sure the screening bucket you are considering is compatible.

How many yards per hour can a skid steer screening bucket process?

Typical throughput ranges from 10 to 25 cubic yards per hour, depending on material type, moisture content, screen opening size, and operator technique. Dry, free-flowing topsoil screens at the higher end of that range. Wet or clay-heavy material drops production significantly.

Is a screening bucket worth it for a small landscaping business?

For many small landscaping operations, a skid steer screening bucket is one of the best equipment investments available. If you already own a skid steer, you add screening capability for $6,000 to $20,000 instead of $50,000+ for a standalone screener. The screened product sells for $15 to $25 more per cubic yard than raw material, so the bucket can pay for itself within a few months of regular use.

What is the difference between a vibrating screening bucket and a rotary screening bucket?

A vibrating screening bucket uses a hydraulic motor to shake a flat mesh screen. Material falls through the mesh openings as it vibrates. This design is simpler, less expensive, and works well with dry, free-flowing material. A rotary screening bucket uses rotating drums, blades, or star discs to tumble and separate material. Rotary designs handle wet, sticky, and clay-heavy material much better because the rotation is self-cleaning. Rotary buckets cost more but offer greater versatility.

When should I upgrade from a screening bucket to a standalone screener?

When your screening volume consistently exceeds 20 to 25 cubic yards per hour, or when you find yourself screening for more than half of your working day, a standalone screener will improve your productivity and product quality. Screening buckets top out at roughly 150 to 200 cubic yards per full working day. A small shaker screen or trommel can double or triple that output with one operator.

Browse impact crushers for sale from Rubble Master, McCloskey, Metso, Sandvik, KPI, and other manufacturers. An impact crusher uses high-speed blow bars or hammers to shatter material on contact, producing a cubical, uniform product shape ideal for road base and spec aggregate. GrinderCrusherScreen carries new and used impact crushers for concrete recycling, demolition, and aggregate production. Call 770-433-2670 for pricing and availability.

How an Impact Crusher Works

Material enters the crushing chamber and hits a rotor spinning at high speed. The rotor throws the material against heavy blow bars, anvils, or impact plates mounted inside the chamber. The material shatters on impact rather than being squeezed. This produces a more cubical product shape than compression crushers — an important spec for road base, concrete aggregate, and asphalt production.

Impact crushers handle rebar-laden concrete better than jaw crushers because the impact action breaks the rebar free from the concrete. A magnetic separator on the discharge conveyor then removes the freed rebar from the product stream.

Impact Crushers vs. Other Equipment

For hard rock primary crushing where a cubical shape is not required, jaw crushers offer lower wear costs and handle larger feed sizes. For asphalt shingle processing and mixed C&D material, concrete and asphalt shredders provide primary size reduction before the crusher.

What to Check Before You Buy

Inspect the blow bars for remaining thickness and even wear. Check the rotor for cracking and balance — an out-of-balance rotor causes destructive vibration. Inspect the aprons (impact plates) for wear and proper adjustment. Check the crusher frame for stress cracks around bearing housings. Review engine hours and hydraulic system condition.
