In many plants that process bulk materials, the product is vibrated to energise it and minimise friction against container walls and particle-to-particle cohesion. This makes the material easier to transfer, feed, sort, and condense.
Proper installation is key to a successful quarrying operation. The feed system, supporting structure, and frame must be correctly built to maximise equipment use and withstand dynamic and static screen forces. Here are some FAQs about vibrating equipment setup and operation.
What Factors are Considered Important When Creating a Structure?
Larger screens need strong, solid supports. If the framework isn’t sturdy, the screen’s vibratory movement will diminish, causing the supporting structure to vibrate and amplitude and phase disparities on each side.Consider the screen’s static and dynamic forces when calculating the frame’s strength. The structure’s resonance and harmonics must be different from the screen’s vibrating frequency. If the screen’s speed coincides with or is close to the natural frequency of a building component, the vibration will hurt both. This can cause personal injury and equipment damage.
Vibration levels shall not exceed the maximum permissible limit. The supporting structure or frame’s structural frequency should be at least 2.5 times the equipment’s operating frequency.
What is the Role of the Feed Arrangement in this Process?
Feed chute architecture is one of the most critical design aspects to optimise classification, increase the life of liners and screening media, and maintain the vibrating screen’s structural integrity. To maximise the equipment’s screening area, feed material must be distributed across its entire width. Restricting the drop height between the chute and equipment liners extends wear life and reduces structural collapse danger.
The feed material should be placed over feedbox liners rather than directly on screening media to prevent early wear. Elevating the feed material above the screening medium does this. When possible, internal deflector plates can be placed on the chute to slow material feed. Slowing feed speed reduces wear and improves categorisation.
Most Important Thing to Keep in Mind When Installing Vibrating Screens and Feeders?
The main vibrating feeder absorbs impact and regulates the primary crusher feed. Vibrating pans must be coated to absorb shock, retain feeder structure, and extend wear life. The feeder bin’s design protects the main crusher when the material is emptied. It must be high enough to avoid leakage at the feeder’s discharge end. Build a preliminary chute before the feeder hopper to lengthen the distance between the discharge point and the vibrating pan’s end. When this happens, stones may fly above the primary crusher and damage it. A chain or tyre between the feeder and crusher can decelerate truck-unloaded rocks.
