EQUIPMENT PROCESSING SANDVIK DRILLING CUSTOM MANUFACTURING MACHINE SHOP PAINT BOOTH SERVICES SCREENING 101 Aggregate & Rock Screener All industry experts in the rock crushing business know that the rock screener is an essential part of their trade. Many different types of screeners are designed for specific geological situations, desired efficiency, energy intensiveness, and more. Below is a list of other variables that affect the kind of screener that you will need. Find out why are rock screens important for your rock crushing company. 1. What type of material are you screening? You can estimate the proper amount of material that should be screened per hour more precisely if you consider the geological nature of what will be processed. 2. What is the planned amount of material per hour? Miscalculating maximum load can cause catastrophic results in your aggregate screening operation. It may cause spoilage in the material you are processing due to overloading and spillage. The whole project may grind to a halt as a result. 3. What is the capacity required in tons or gallons per hour? These variables should be expressed in both average and maximum peak loads. Exceeding the screener's peak load, even for a short duration, may result in the spoiling of products or may upset subsequent steps in the project due to the drop in screening efficiency. You should ensure that there is sufficient screen area in your machine to handle the maximum load. 4. Is the screening wet or dry? Moisture levels are important because they change the amount of water you can add before problems arise. Too much water may make the material impossible to screen. 5. Although unusual for most applications, temperature may be a concern in some projects. Bearings can stop working in high heat, and plastic parts may melt. 6. Is the material sticky? The type of wire cloth that you should use depends on this variable. 7. Is the material abrasive? This variable determines what type of wire to use in screen cloths— additionally, you may need to install protective plates within the system. 8. Are you screening any corrosive materials? If so, using corrosion-resistant materials is necessary. Otherwise, the screener will deteriorate quickly. 9. What shape are the individual particles? Screens used for one type of aggregate may not work for another type, even if the individual pieces are approximately the same size. The holes in the screens must be fitted specifically for the kind of material in question. 10. How much dust? Dust can cause long-term health problems in humans, and it can affect certain types of machinery negatively. Dust covers or enclosures may be a good choice if dust is a problem. 11. Is oversize crushed again? Whether it is or is not will affect the amount of material that can go through the screener per hour. Not taking recirculated oversize into account can cause overloading of the screen and subsequent problems involving wasted product and lost time. What type of aggregate screen is best for you? GIVE US A CALL TODAY At JW Bell, we can design and build whatever type of aggregate screening equipment is necessary for your business. We understand that having the right equipment can mean the difference between success and failure. We are known as a trustworthy company in our industry- we have been in business since 1923. Over the time since, we have forged relationships with many businesses that have lasted until today. We have taken years to hone and develop our designs to give our customers the best performance. Our representatives will guide you through what type of aggregate screen is best for you. Before you talk with us, you may find it useful to get an overview of some of our capabilities. Below are a few of the main types of rock screeners that we can make. Different Types of Equipment used for Screening Rock 1. Grizzly Screener Usually, once the material has gone through the crusher, the first stop for the material is the Grizzly Screener. It consists of a long sloping trough containing different levels of parallel bars that are spaced according to what needs to be filtered. The bars are made from a wear and impact resistant alloy- many other types of steel cannot stand the constant impact and abrasion that the bars in the screener must go through. 2. Dewatering Screener The Dewatering Screener gets rid of water and debris that has to be separated from the aggregate. You can use it purely to get rid of water or use it to add water to rinse away dust and other small particles. Like the Grizzly Screen, it has an incline. However, it also has motors that produce linear motion, forcing larger objects to the top of the screen and smaller objects downward into a channel that washes them away. 3. Horizontal Linear Screener Unlike the Dewatering Screener, the single or double deck Linear Screener lies horizontally. It uses motors to shake the apparatus so that it filters the material through the screens. One benefit to this type of screener is that it can be highly portable and compact. If it is impossible to achieve the grade necessary to run a gravity-operated incline screener, a horizontal screener may be your best choice. 4. Banana screener The Banana Screener is a novel design that can increase efficiency dramatically. It consists of sloping decks that can screen rocks quickly. One drawback is that the screens must all have different hole sizes depending on where they are on the deck. One benefit ion the Banana Screener is its adaptability - You can change the motor speed and screen type on-site. Contact Us First Name Last Name Email Send Terex Simplicity Dual Mechanism Two-bearing inclined screens are the rugged machines that you need for those heavy jobs. The tough design extends bearing life in heavy-duty applications and handles increased speeds in fine screening applications. Terex MPS says they are built with a robust drive mechanism and oversized bearings to handle large tonnages and a wide variety of applications. Utilized as wet or dry screens, these units have an adjustable stroke and speed combinations to fit a variety of applications and are available in two- or three-deck configurations. They are fitted with woven wire media but can be converted into modular media with polyurethane, rubber media, or steel plate without any cutting or welding.
