guide to bucket crusher hydraulic attachments - construction & demolition recycling
Bucket crusher hydraulic attachments increase the versatility of carriers and can help make efficient work of handling and processing concrete debris, rubble, masonry, asphalt, natural stone and rock. They allow operators to process upwards of 100 tons of material per hour while requiring less on-site equipment, less transportation and reduced dumpsite costs.
A bucket crusher is composed of a small jaw crusher mounted on a carrier. The most common setup features a bucket with a fixed bottom and one moving jaw that crushes the material against it. An eccentric element mounted on an axle and rotated by a hydraulic motor moves the jaw.
Contractors use bucket crusher attachments to crush material into right-sized piecesfrom three-quarters of an inch up to 6 inchesand reuse it as backfill at the site or transport it for use elsewhere.
On building sites, operators frequently crush excavated stone so the subsequent aggregate can be used for construction. In quarries and gravel pits, contractors often use these attachments to crush boulders after prescreening and small amounts of soft stones. Demolition contractors rely on these tools to make quick work of processing materials generated on-site without the need for standalone crushers.
Whatever the application, the bucket crusher attachment provides a cost-effective alternative to transporting large pieces of material to a dumpsite or recycling yard. While a bucket crusher is generally not a replacement for a portable rock crusher, it can serve as an alternative to a traditional crusher in confined areas, such as worksites in urban areas.
Bucket crusher attachments are available in a variety of sizes. To select the right size of bucket crusher for the application, contractors should first determine the size of the carrier that will be used with the attachment to assure it does not exceed the carriers capacity.
To select an appropriately sized crusher, a few things need to be determined: the size of the material that will be crushed, how much material needs to be crushed and the existing pieces of equipment in an operators fleet.
Professionals should select a crusher with a drive system robust enough to generate the proper torque for the application. They should also look for crushers that have a reverse function to keep material from jamming the equipment; buckets with sliding plates that help guide material to the crushing jaw to help increase throughput; and a system that allows for quick material grain size adjustment to increase uptime.
In general, contractors should seek a bucket crusher attachment with high-output performance, excellent usability and low maintenance needs. As with all heavy equipment, contractors should rely on established manufacturers with a dedicated support staff so that any issues can be quickly remedied.
When operating the bucket crusher, safety is paramount. Operators should only use the attachment when the carrier is in place and stable. Before starting the bucket crusher, operators should always ensure that the attachment is complete, the bucket crusher and adapter plate do not have any cracks and the hydraulic line connections arent leaking.
Once a perimeter is secured and the carrier is in place, a functional test should be performed before putting the attachment to use. During this test, its important to assure all hydraulic lines and connections are tight and that the bucket crusher works as intended. To do this, the operator should load the crusher with material and gradually size it until the maximum number of revolutions has been reached. Should there be a blockage of material during testing, the bucket crusher should be stopped and reversed. Operators should never try to remove jammed obstacles manually, as this can lead to serious injury. If the jaws are still blocked, the operator can rotate the bucket crusher to help clear the blockage.
Prior to each shift, operators should examine the crusher and adapter plate for cracks and deformations. Operators should also check the transmission housing and hydraulic lines and motors for leaks and damage. All connections should be tightened to spec. If the plugs on the shaft-pulleys show any signs of wear or damage, or if the conditioner of the tensioner system or wedges and jaws is suspect, immediate service is required.
The fixing screws of the wedges and the bolts and fixing screws of the tensioner system should be examined and tightened as needed during the first 50 hours of operation. While there is no replacement for daily monitoring, observing the manufacturers recommended service intervals can help preserve the life of the equipment and maintain its performance.
Common preventative maintenance on these systems includes checking the oil filter cartridge and replacing it when necessary. Maintenance technicians should also be mindful to replace jaw wedge fixing screws, damaged hoses, and bent and damaged pipes as needed. Finally, operators should check and/or replace lubricant and control block seals based on intervals recommended by the manufacturer; however, extreme changes in temperature can expedite the need for service.
While the right bucket crusher hydraulic attachment can efficiently handle a variety of materials, it is vital for contractors to find the right fit for their individual needs and emphasize regular maintenance to get the most out of their investment. By doing their research, speaking with manufacturers and testing out equipment, contractors can take the right steps toward maximizing their processing capacity while cutting down on transportation costs in the process.
Large-scale commercial demolition projects and building teardowns often lend themselves to straightforward recycling opportunities for contractors. High-volume materials, like concrete and wood, and high-value materials, like metal, are systematically cherrypicked from sites and subsequently recycled. But what happens when a demolition contractor generates materials that arent easily processed through traditional recycling methods? That was the challenge facing the team at South Gate, California-based Interior Removal Specialist (IRS) Demo as its business picked up steam over a decade ago. Looking for a better way to divert interior debris from landfill and meet local recycling ordinances, the IRS team decided to start its own recycling business, Construction & Demolition Recycling Inc. (CDR Inc.), which received its first solid waste facility permit in 2007.
We didnt have a choice if we wanted to meet the requirements of cities like Santa Monica and Pasadena that had a 50-percent diversion mandate for these demolition jobs at the time, says Richard Ludt, the director of environmental affairs for CDR Inc. The only thing we could do was start a facility that targeted the materials we were hauling.
CDR Inc.s seven-acre processing facility is headed up by Ludt and Vicky Herrera, the companys corporate officer and field operations manager. It is the only construction and demolition (C&D) facility in California that solely recycles tenant improvement demolition debris.
While the facility is permitted to take in 3,000 tons per day (TPD) at full capacity, Ludt says the company is only processing between 250-300 TPD currently. However, he expects that to change soon. CDR Inc. recently obtained hauler permits in many of its surrounding cities that will allow it to better serve the C&D management needs of area contractors. With these permits in place, Ludt says the facility is poised to increase its incoming tonnage.
We have broken away from being a recycling facility that just serves one customer, Ludt says. We have become a fully independent facility with our own dumpster rental, hauling and collection operations.
Though the composition of its incoming material stream fluctuates, CDR Inc. presently enjoys a 79 percent diversion rate. The facility diversion breakdown averages are as follows: 27 percent drywall, 14 percent metals, 13 percent wood, 10 percent carpet, 9 percent concrete, 4 percent ceiling tiles and 1 percent each of cardboard and salvaged/donated items. Only 21 percent of outgoing material is trash or contaminated material.
To process its recyclables, CDR Inc. relies on a portable sort line from the Qubec-based Sherbrooke OEM and a trommel from Crystal Lake, Illinois-based Tuffman Equipment. Ludt says CDR Inc. favors a more low-tech approach via manual sorting to avoid crushing incoming drywall, which accounts for the largest percentage of its incoming material. However, Ludt says CDR Inc. is presently weighing the benefits of adding new equipment to better sort its incoming cardboard, plastics and glass.
Were very lucky in California that the soil needs gypsum. Were shipping 1,200 tons of gypsum every month to farmers to use in [agriculture], so that takes care of 30 percent of our inbound material right there, Ludt says. Most of the wood were getting is going to waste-to-energy use because almost all of it is manufactured lumber, although we do donate the small percentage of dimensional lumber we do get from public loads to various beneficial reuse projects. Were also very fortunate in that a lot of the carpet we get is carpet tile. Because we have the ability to keep it clean in our warehouse, we donate tens of thousands of square feet of carpet every year to nonprofits that reuse it in places like homeless shelters, childrens centers and battered womens shelters. As for our fines, we had been using them for cover for a while, and then we cleaned them up enough that they were going for [agricultural] uses for non-human consumption crops because theyre predominantly gypsum-based coming out of our facility, but now, theyre getting mostly used for road stabilization. Even then, fines make up less than 10 percent of our weight.
Beyond recycling and reusing material, Ludt says CDR Inc. has established a robust donation program. Because of the companys focus on commercial interior work, CDR Inc. receives a lot of gently used furniture from companies that are moving offices or undergoing renovations.
When we get furniture thats still in good shape, we have a program to repurpose it. We have a 100,000-square-foot warehouse, so were putting that furniture in the warehouse and were making it available to any nonprofit that wants it, Ludt says. Were currently donating anywhere from 30 to 60 tons of furniture and fixtures every month. Everyone from dog rescue centers to the Church of Scientology to fire departments has access to our goods. As long as it can go to somebody that needs it, it would be criminal to let this really expensive furniture go to the landfill.
Specializing in interior demolition recycling isnt an easy vocation. Beyond familiar challenges in finding end markets, the nature of the projects that generate CDR Inc.s incoming materials often make it difficult for source separation.
The biggest issue with commercial interior demolition as far as diversionand I dont care who is doing the demo workis the fact that most high-rise buildings in the California market only have room for one dumpster in the loading dock, so you cant do a lot of source separation, Ludt says. That creates a challenge, because we all know the easiest way to keep materials clean is to have a separate box per material. But that doesnt work in a commercial high-rise. On a larger scale job, it gets a little bit easier. But on a smaller scale job, if youre only doing 5,000 or 8,000 square feet of demo, then you have no choice but to put all the material in one box, and its difficult to keep those materials clean enough to divert.
At the end of the day, weve kind of made it tough on ourselves just to prove [diverting this material] can be done, Ludt says. If disposal is $35-$40 per ton, processing is $50-$70 a ton and youre bringing in $90-$100 a ton at the gate depending on what facility youre at, you can make it make financial sense, but its hard when were going up against people who own landfills or have more traditional C&D commodities.
We do have the advantage that were in California and there is legislation that mandates a certain level of recycling, Ludt adds. Moving forward, the state, Los Angeles County and the city of Los Angeles all have some pretty aggressive zero-waste plans theyre aiming for, which puts us in a good position. If the state, county and the cities are serious about zero waste, then eventually everybody is going to have to start looking at recycling commercial interior debris the same way we do.
Ludt says CDR Inc. doesnt just strive to divert material from landfill to comply with local regulations. The company does it because its the right thing to do for both the community and the environment.
We could make more money doing it an easier way. We could drop the price of concrete inbound to our facility and we could bring in tons and tons of concrete and wood and not have to process so much of that interior debris and increase our profit, he says. But one of the things we say around the yard is once you know the damage this stuff can cause, you cant unknow. Once you know what drywall or manufactured lumber does when it gets into the landfill and all of those chemicals turn into harmful gases or get down to the leachate that is only being kept out of the groundwater by a plastic liner that has, at best, a 50-year warrantyhow can you knowingly put this material in a landfill?
CDR Inc.s efforts to change the way C&D material is recycled hasnt gone unnoticed. According to Ludt, the company is currently the only C&D facility in southern California to garner Recycling Certification Institute (RCI) certification, making it the only facility in the region eligible to provide the U.S. Green Building Council (USGBC) LEED pilot point for facilities with third-party verification. Additionally, the facility has been singled out on the awards circuit as of late. In just the last six months, CDR Inc. has won the Sustainable Materials Management Award from the Solid Waste Association of North America (SWANA), the Recycler of the Year Award from the Construction & Demolition Recycling Association (CDRA), and the Governors Environmental and Economic Leadership Award (GEELA) from the state of California, which is the highest environmental honor in the state.
In the space of six months, we have been recognized by the state, internationally through SWANA and called out specifically within the C&D recycling industry with the CDRA award, so thats kind of like the holy trinity in this industrythe words getting out, Ludt says. Its nice to know that somebody gets it because it does get frustrating to be doing it right and sometimes feeling like were the only ones who are, and I know thats not the casethere are other good people out there. But to get that recognition that somebody understands that what were doing has some meaning. That means a lot to us.

Construction employment grew in 273 out of 358 U.S. metro areas between December 2017 and December 2018, according to an analysis of federal employment data recently released by the Associated General Contractors of America (AGC). Industry employment declined in 37 metro areas and remained stagnant in 48.
Construction employment continued to expand in most parts of the country in 2018 as demand for many types of construction projects grew, says Ken Simonson, the associations chief economist. As welcome as the job gains were, many firms would likely have added even more workers if labor market conditions were not so tight.
The Houston-The Woodlands-Sugar Land, Texas, metro area added the most construction jobs during the past year (19,400 jobs, 9 percent). Other metro areas adding a large amount of construction jobs over the past 12 months include Dallas-Plano-Irving, Texas; Phoenix-Mesa-Scottsdale, Arizona; and Orlando-Kissimmee-Sanford, Florida. The largest percentage gain of 28 percent occurred in the Weirton-Steubenville, West Virginia/Ohio area.
The largest job losses in that time period occurred in Anaheim-Santa Ana-Irvine, California (-2,800 jobs, -3 percent), followed by San Diego-Carlsbad in California and Honolulu. The largest percentage decrease occurred in Lawrence-Methuen Town-Salem, Massachusetts/New Hampshire (-9 percent, -300 jobs), followed by Abilene, Texas; Wichita Falls, Texas; and Elmira, New York.
Association officials say workforce shortages are limiting the full economic benefits of robust demand for construction. They urged federal officials to increase technical education funding and enact immigration reform to allow more people to legally work in construction.
