New-type electromagnetic feeders that are easier to use

Based on tried-and-tested technology, these small electromagnetic feeders for the supply/discharge of particulate materials are now much easier to use. The addition of a variable frequency controller, supplied as standard, eliminates the need for delicate leaf spring adjustments. Tuning is simple and requires no experience. These new models also feature increased delivery capacity, and outstanding durability. Ideal for supply, small-volume precision supply, and discharge of superfine powders and all other particulate materials.

Features

1. Variable frequency controller, supplied as standard, delivers variable output frequency unrelated to frequency of power source.
2. Requires no leaf spring adjustment, and no experience for perfect resonance point tuning.
3. Set voltage function keeps amplitude constant, regardless of power source voltage fluctuations.
4. High vibration amplitude of max. 1.6mm boosts delivery capacity by 30% over former models.
5. Drive unit sealed in durable plastic casing (CF-1, 2, 3) and Stainless Steel (CF-4) keeps out dust and powder, to extend working life.
6. A wide range of trough designs can be accommodated, to suit user requirements.
7. With the addition of an optional standard amplitude controller, amplitude can be kept constant through changing loading conditions. (except for CF-4)

Operating Principle

Electromagnetic feeders consist of a trough for material handling, electromagnets as sources of vibration, and leaf springs. When electromagnets are excited by currents from a controller, the trough is rapidly pulled down below. This is due to the pull speed being quick, which results in handling material float for a moment, and then a fall forward on the trough. By recoil of the leaf spring, the trough is pushed back to a fixed position. Materials are conveyed through these movements. The movement is repeated 2700 times per minute. As the movement is extremely fast, conveyance is smooth and material is not harmed.
