Vibrating screen mesh is widely used in vibrating screen machines to filter and separate sands, gravel, coal, stones, rocks and other wet and dry materials. Our vibrating screen mesh is made of high tensile spring steel, manganese steel, stainless steel and polyurethane. So it is not easily to be damaged and deformed by these materials. And vibrating screen mesh has good adaptability. It will not be damaged in high temperature or low temperature environment.
The quarry vibrating screen is mainly used to screen gravel, and the quality of the screen mesh determines the material screening efficiency. Therefore, quarry investors or equipment purchasers will ask the manufacturer for information about vibrating screen media types when choosing a vibrating screen.
Rayco designs and manufactures a complete set of high quality and cost-effective rubber screens. They are used to treat the roughest and most abrasive products, such as gravel, coal, slag, etc. Rubber material is soft and powerful, can absorb shock and have long service life, which not only can reduce the downtime, but also makes installation easier and faster. If noise reduction is required, rubber screens are good choices.
Rayco rubber sieve can be divided into two kinds: tension and modular. The tension type can be installed as a circular vibrating screen and replace the original metal screen or polyurethane screen. The modular type can be installed in many ways, which can better save operating costs.
The polyurethane screen is made of polyurethane and embedded in a steel frame. It has a specially designed fastening hook to clamp the mesh to the separator. Polyurethane screen has excellent performance in mining crushing and aggregate screening industry. Different sizes and types of mesh hole ensure high screening efficiency and smooth surfaces. Polyurethane materials make mesh noise much lower than braided vibrating mesh or perforated mesh.
Our polyurethane screens can effectively screen materials for many industrial applications, such as dehydration, mining, sand, stone, gravel, etc. Polyurethane is ideal for high wear areas in both wet and dry processing applications.
THe high-strength woven wire screen is made of best steel wire like manganese steel wire, galvanized steel wire and stainless steel wire. The mesh hole can be square, rectangular, or longslotted. With a variety of woven types, it can be suitable for different screens and materials.
The perforated screen is made of a metal plate with high compressive strength after punching. Compared with woven vibrating screen, porous vibrating screen has a smooth surface, which can ensure higher screening and separation efficiency.
A third-generation family quarrying business is maintaining its commitment to quality across changing seasons through its decades-long preference for sophisticated and optimised vibrating screens and their screen media.
The Peace River region of northeastern British Columbia, in Canada, is often associated with rich soils and moderate temperatures, making it an ideal agricultural environment. But there is also plenty of income to be made just below the surface. An aggregates producer recognised this in the mid-1960s and decided to take action.
In 1966, Nels Ostero established a sand and gravel operation in the Peace River Region Nels Ostero Ltd. Since then, the company has grown significantly but has always remained humble and family-orientated. Nels Osteros son Tom Ostero took over the plant in 1982, and in 2007, his grandson Nilson Ostero assumed the manager position where he remains today.
The plant, which resides on 130 hectares of land, supplies sand and gravel for residential and commercial needs in the Peace River regional district. The companys products are used in concrete applications, asphalt plants, oil fields and highways. With a capacity of more than one million tonnes per year, the equipment on-site plays a huge role in the plants success.
To keep up with the demand of sand and gravel products, the quarry requires top level machinery. There are 11 vibrating screens, two crushers and dozens of loaders, trucks and excavators on-site, all of which need to be performing efficiently.
Haver & Boecker Niagara has been delivering dependable equipment to Nels Ostero for decades. In fact, the Canadian-based screen manufacturer has been Nels Osteros go-to since the quarrys first years of establishment, back when the manufacturer was known asWSTyler.
The first piece of Haver & Boecker Niagara equipment the company purchased was a Ty-Rock (today known as an F-class vibrating screen) installed in 1966. Since then, they have added a number of technologies from themanufacturer.
My father chose the company because of the reliability of the equipment, Nilson Ostero said. I have tried some different equipment and screen media brands over the years, but nothing compares to Haver & Boecker Niagara.
Most recently, Nilson Ostero replaced his two 4.8m x 2.1m machines, which were situated at the finishing end of the operation. They were supplied by another manufacturer and had been running since the 1980s. The equipment was outdated, inefficient and required more maintenance than the value they offered. He turned to Haver & Boecker Niagara which evaluated his operation and recommended implementing two Niagara T-class machines. The new screens have proven themselves a good fit, increasing capacity and requiring little to no maintenance.
The T-class machines are on their third season with us, and we havent had a single issue, Nilson Ostero said. They allow us 20 per cent more capacity than our old screens, but more importantly they are stronger andmore reliable.
Haver & Boecker Niagara characterises the T-class machines as highly efficient and durable, which is important to the success of any screening business. This is especially true for this particular operation, which runs year-round and sees the effects of cold weather on material and screening equipment.
The British Columbia winter weather averages about four degrees Celsius but can dip down as low as -40oC. While some screen plants shut down their whole operation in the winter, Nilson Osteros high performing equipment allows him to performcrushing and screening year-round. When temperatures remain steadily below -3o C, they pause aggregate washing. However, even with a portion of the operations process shut down, they are still able to produce more than an operation that has to completely shut down for several months.
The colder it gets outside, the stickier the material becomes, Nilson Ostero said. The extra moisture can lead to blinding and pegging, resulting in downtime for maintenance to clear out the material. That doesnt happen with the T-class machines.
At the end of the day, if the guys are working with good equipment, they are happier and perform better, Nilson Ostero said. Safety is obviously a big deal, but another thing is providing efficient, top-notch machines that dont require unnecessary maintenance.
Maintenance is required on all jobsites, but unexpected maintenance and subsequent shutdowns can equate to a significant loss of money for any company. Scheduled maintenance activities are only possible with thorough analysis and planning as well as quality equipment and screen media. Nilson Ostero consistently found that any attempt to cut corners only resulted in lost profits. Each time he experimented with lower-cost screen media, he would watch as unexpected downtime and lost revenue skyrocketed.
Until the operation implemented the Haver & Boecker PROdeck method, the standard screen media required attention after every eight shifts, and a complete change-out every two weeks. PROdeck evaluates the screening process to effectively blend screen media for the highest production with the least amount of unscheduled downtime. Markus Kopper, general manager of Haver & Boecker Niagara Rocky Mountains, and Dave Warden, Haver & Boecker Niagara sales manager, worked with the company to determine the optimal screen media combination for the operation. This included a combination of Ty-Max, Ty-Wire and traditional woven wire, as well as Majors Flex-Mat.
Haver & Boecker Niagara partners with each customer and thoroughly evaluates an operation before making recommendations, Kopper said. For Nels Ostero, they were able to achieve a 70 per deck increase in wear life with our PROdeck approach.
Nilson Ostero also consulted with Haver & Boecker Niagara to determine if any additional upgrades for his vibrating screens could reduce the time required for maintenance and screen change-outs. Hefound a time saver in the companys Ty-Rail quick-tensioning system. The new T-class machines are equipped with this system, which combines the tension rail and all hardware together in one assembly. Ty-Rail has simplified the process and saves his team at least three hours each time a change-out is needed, as well as helping to eliminate losing nuts and bolts into the hoppers below.
A complete screen change-out, on one screen, would have normally taken us five or six hours, Ostero said. But with Ty-Rail, we can do it in as few as three hours. And guys arent dropping bolts every 15 seconds, so thats anadded bonus.
The three-hour time savings, coupled with increased throughput, resulted in an overall production increase over the first year. On top of that, it saved an estimated eight to 10 days of downtime per season, which equates to an increase of thousands of dollars.
However, Ty-Rail wasnt the only time-saving option Nilson Ostero discovered. After years of frequently replacing worn out cross-beams, he opted to add Zip-Guard to his T-class machines. The 13mm-thick polyurethane liner is designed to reduce the impact of passing material by protecting the cross beams from wear. This results in increased equipment longevity and minimised downtime formaintenance.
All of the technologies on-site are supported by an ongoing service program, which gives Nels Ostero an added level of confidence in the products. Haver & Boecker Niagara begins every service visit with its signature Pulse vibration analysis. The advanced vibration analysis technology is designed to help customers, like Nilson Ostero, examine the health of their vibrating screen. Haver & Boecker Niagara technicians use the technology and analysis to help detect irregularities that could translate into diminished performance, decreased efficiency, increased operating costs and imminent breakdowns.
Markus and his team used Pulse to help me spot issues that our team wouldnt have normally been able to find, Nilson Ostero said. Haver & Boecker Niagara first ran it on my machines right after they installed them, and now they run it once a year. It has caught problems that may have cost me money down the road, including a twisted frame on one of my screens. We knew there was a problem with the unit, but with Pulse, Haver & Boecker Niagarasservice technician determined exactlywhat was wrong.
Since the companys inception, Nels Ostero has grown to become one of the largest sand and gravel producers in the area employing more than 30 people, several of whom have been with the company for more than 15 years. With a constant focus on relationships and quality, the Ostero family built a longstanding business on enduring whatever the economy throws at them, all while maintaining their reputation for consistently providing quality product that meets the demands of theircustomers.
Looking toward the future, Nilson Ostero hopes to continue to grow the business by increasing output year over year, continue retaining and adding employees, and perhaps most importantly keep the businessin the family and one day pass it on to his children tocontinue the family tradition.
As the distinctive identities of many products in the crushing and screening sector give way to rationalisation over time, one OEM is staying dedicated to offering the aggregates industry the best of its screens and feeders across five different brands. John Flynn explains.
Between them, these five brand names have more than 500 years of operating history and have an enviable record of providing premium feeding, crushing and screening equipment to the quarrying industry worldwide.
Each quarry site has its own unique conditions in relation to location, raw material characteristics, layout of site and surround and production requirements. As such, a one size fits all approach isimpractical.
Whereas some global construction companies have heavily rationalised their equipment range after acquisition, Terex MPS has retained and developed the technology of its brands through its growth phase, allowing a machine of best fit approach when it comes to recommending equipment for its customers. A good example of this is with the Terex MPS rangeof vibrating screens.
After many years of providing an industry-leading linear motion design, Cedarapids pioneered the triple-shaft elliptical motion screening machine. The current Terex TSV also has the unique ability among horizontal screens to be installed at various slopes to resist pegging and enhance control of material velocity.
The primary advantages of the horizontal screen such as the Cedarapids TSV is that it presents a low head height for ease of installation and will outperform an inclined screen of similar size, the high G-force providing the ability to stratify and separate large quantities of material. It is ideal for mobile applications and installation into greenfields crushing plants or new screening stations.
The inclined screen has its own advantages as a cost-effective solution across a broad range of screening applications. From primary scalping to finish screening, fitted with grizzly bars, steel plate, modular or cross-tensioned screen media, screening wet or dry, the inclined screen presents a versatile solution across the full range of screening requirements.
The Terex Simplicity and Jaques Torrent inclined screens are designed for a multitude of applications. Thousands of these inclined screens having been placed into operations in North America, Australasia and South East Asia. A high percentage of these have been as replacement of Terex or competitor units or to fit a specific envelope.
The Simplicitys screen design produces a balanced vibration to minimise stress and fatigue. The shafts utilised in the Simplicity screens are cut specific to each unit and designed for smooth, reliable operation and the longest service life available.
The Jaques Torrent screen has been a mainstay of the Australian quarrying industry for many decades, as generations of quarry operators have profited from the high performance, long life and reliable operation of these units.
Now Terex has used all of its screening experience to develop a newly released screen range combining features of the Simplicity and Torrent screen designs. The Terex SI screen is the newest addition to the Terex MPS static screening range. Constructed with ease of maintenance in mind, these screens feature additional clearance between decks, removeable spring base plates, hand-hold access to screen interiors and are built with oversized bearings to ensure maximum performance and longevity. Vibrating motion is provided by a combination of an unbalanced shaft and bolt-on counterweight plates. The shaft provides the bulk of the motion, ensuring smooth operation and minimal transverse movement, which can result in frame failure. The bolt-on counterweight plates facilitate stroke adjustment to finetune screen operation. The screen body and deck construction are engineered to eliminate high stress areas and fatigue allowing for longer service life.
Huck bolts secure the frame connection with about 10,000psi (each), effectively joining together the segments of steel. The screen deck design includes a conversion kit which can adapt standard cross-tensioned screen decks to accommodate modular media.
