Aggregate & Rock Screeners
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 for consideration when choosing the screener that suits your needs.
Find out why rock screens are important for your rock crushing company.
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.
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.
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.
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.
Is oversize crushed again?
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?
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. 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.
Types of Equipment Used for Screening Rock
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 that can stand the constant impact and abrasion the screener goes through over other types of steel.
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 to add water to rinse away dust and other small particles.
Like the Grizzly Screen, it has an incline. In addition, it 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.
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.
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.

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.
JW Bell is the best choice for equipment to help you when screening rock. We can design a custom rock screener to suit your operation, and we can guarantee that you will be happy with our products and service.
