Circular Vibrating Screen

The circular vibrating screen moves in a circular motion. It has multi-layers and is of high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line.

The Overview of Vibrating Screen

Vibrating Screen is used to separate materials into various sizes for further processing or for end use dependent on your conditions. The material is separated by passing through a vibrating “screen box” which has a number of different sized screens, or meshes, through which the material falls through like a sieve, and to the attached conveyors to become end products. The end products can then be used in the building and construction industries.

Vibrating Screen is widely used for grading and screening materials in the following fields: minerals, quarry, building materials, water conservancy and hydropower, transportation, chemical industry, smelting and so on.

Vibrating Screen Benefits

• Improve your product purity - Eliminate oversized material from your powders and liquids

• Increase your production - Double your throughput with half the size. These vibrating screens achieve a higher throughput per unit mesh area compared to conventional vibrating screens and can achieve throughput rates up to 60,000 kg/hour

• Reduce your down-time - The Russell Compact Sieve can be easily stripped down and cleaned without tools

• Eliminate dust and fumes - Enclosed screening means total containment

• Fits into smaller spaces - These vibrating screens can fit easily into existing installations and areas of limited headroom

• Lowers noise levels - A solid rubber suspension gives the machine a quiet operation - typically as low as 70dBA

Operating and cleaning is quick and easy, making this range of vibrating screens perfect for all processing industries. A wide range of sizes and options means the machine can be tailored to suit your exact needs.

The usage and maintenance of circular vibrating screen

• Before starting, we should inspect every fasteners bolt if there is any looseness. If there is, we should fasten it one time.

• After the sieve machine has empty motion for 4-6 hours, the sieve body should be steady. No sway and unusual sound and driver bearing temperature ≤7512.

• After idle operation, we should examine every spots spiral and fasten one time.

• In normal work, it should have periodic inspection of every fasteners bolt tight situation.

• Inspect vulnerability, the use and maintenance frequently; please refer to the instruction for use. (vibrating motor should be refueled one time after 3 months, driver be refueled one time every month, a minor repair half year, a overhaul one year.)

• Before parking, you should stop giving the material first and waiting for the screening surface material to walk.

• In the work process you should observe the sieve machine operational aspect continuously; if there is abnormal movement or unusual sound, you should shutdown the machine and check, discover the reason and then remove difficulty.

The purpose is to understand the overall situation of sieve, and to repair or replace damaged, worn parts to make it work. The work includes daily maintenance, regular inspection and repair.

1. Daily maintenance

Check screen surface, particularly the fastening situation of screen surface. If loose, fasten it. Regularly clean sieve surface.

2. Regular inspection

It includes weekly inspection and monthly inspection.

1. Weekly inspection. Check the tightening conditions of exciter, screen surface and supporting devices. Tighten where are loose. Check transmission status and the use situation of locking bolts. Check the belt tension level, if necessary, appropriate tension. When check sieve, pay attention to whether the imbalance weights in the flywheel are fixed reliably. If not reliable, when it is running, the unbalanced weights may be out of the flywheel, resulting into accidents.

2. Monthly inspection. Check the wear condition of screen surface. If find significant local erosion, take the necessary measures, such as exchange location, etc, and re-tighten the screen surface. Check the screen box, check the main beam and the entire main beam welding, and carefully check the local cracks. Check all bolts situation at sieve box side, when find loose between clearance and side bolts, replace the new bolts.
