Everything You Need to Know About Rock Screening Machine

Depending on the specific aggregation, a rock screening machine fits a material handling operation at different points. Its screens size can separate the material after crushing. Meanwhile, choosing the right ones can be complicated if someone is new to the rock or mineral processing industry. Fortunately, here at JW Bell, we're ready to help you set up an efficient circuit that will enhance an operation's overall performance.

If a business is an aggregate or other material handling entity, our screening products will provide valuable benefits for the company. Moreover, choosing a powerful machine will quickly reduce the size of the rock and other materials for purposes. These heavy-duty machines feature a rugged design and construction to handle intense demands. For that reason, this rigorous process delivers an excellent long-term return on your investment.


Types of Rock Screening Machines


Of course, there are different types of rock screening. The number of screening types in style and configuration can be more challenging to quantify. However, focusing on processing in operation will dictate the types of rock screenings in a crushing circuit.

  • Grizzly Screener

Grizzly Screener is used for primary mechanical screening purposes and is fitted between the crusher and a primary feeding. Its result is in a water-resistant end product. That means it is perfect for materials manufactured from high-impact alloys and manganese steel with their disintegration. Unlike your regular topsoil screeners, it is referred to as rock screeners or rock Grizzlys. These are static rock separators that are used to pre-screen bulkier loads. However, if set on an incline, large material slides out to separate larger debris. It would pile damage on the screen. No one wants rocks piling up on their soil screener and ends up on the ground.

  • Dewatering Screener

Dewatering Screeners are used for rinsing, de-gritting, and scrubbing the wet aggregate. It is an output with a drip-free aggregate matter that motors produce linear motion. However, forcing larger objects to the top of the screen and smaller objects downward washes them away.

These are used for processing and drying wet materials with various streams.

  • Horizontal Linear Screener

Horizontal Linear Screener is known for its great operation in a flat horizontal area. However, these rock screenings adjust to 10 degrees in any direction. They have around two or three shafts found within the box's center of gravity. For instance, oval horizontal screens have been designed and integrated with counterweights and timing gears to provide a linear motion. Also, they utilize out-of-balance motors or geared exciters for their linear motion. As these screens operate, they can provide high g-forces for an effective vibration to move the material down.

  • Banana screener

Banana Screener benefits ion is adaptability where a rock screener can be changed. It takes the form of either type BV, type BHG, or type BHR. This machine achieves good separating accuracy at an extremely high feed rate. However, it also has a difficult-to-screen material, making them a high-speed screen with an operational behavior. The banana screen handles the same area for a larger feed quantity, unlike conventional vibrating screens.


JW Bell manufactures single multi-deck versions or gear-driven screens versions. It has different gear unit sizes, which enable outstanding setting-up to suit your specific application. Additionally, balance speeds and masses can be adjusted in stages. This enables the screen box and linear vibration amplitude to optimally adapt to meet process requirements.
