Product Description





Materials: 304 grade stainless steel for detector, 201 grade stainless steel for frame, PVC/ PU white belt.

Belt length (mm): 1600mm.

Conveyor height from belt to ground: 650mm + 50mm feet adjustable, including wheels moveable.

Alarm system: buzzer / warning lights.

Flow speed: 25 m/ min fixed or 10 to 40 m / min variable.

Flow direction: from left to right or opposite(facing control panel).

Language for operation system: English/Spanish.

Electronic source: AC110V/220V, 50/60Hz, Power: 90/120/200W.

Rejection system:

Ø  Stop on Detect Reject(less 50KG) - The conveyor system stops if metal is detected and an alarm sounds, enabling the operator to remove the contaminated product.

Ø  Pusher Reject(10KG) - Pneumatically powered pushers divert contaminated product out of the production flow/ belt, as shown below left picture.

Ø  Drop down Reject - This reject mechanism are typically used to remove contaminated and/or out of spec dry bulk products. Product passes through a chute which in the open position allows good product to continue through. The end flap or lift flap is triggered to divert contaminated or out of spec product out of the good product flow, as shown below right picture.

Ø  Air jet type: NG products are blown sideways off of the line by a powerful air jet. It is ideal for small, lightweight packaged products at high speed.

Our customers:






1.   What is function of the metal detector for you?

The use of metal detector usually has two reasons.

(1) Protects your precious equipment or the essential equipment.

(2) Guarantees your product to be perfect.

If there are metal detritus to mix in your grinding mill, slice, or cutter, it inevitably will create the damage to your equipment. You not only waste the productive time and the money to service your equipment, moreover the metal detritus possibly changes smaller, and it is more difficult to find. If someone had discovered the metal impurities in yours final products, it will destroy the image and the reputation of your company.

2.   Where should l install the metal detector?

If the purpose is for protect ion device, then should install the metal detector in the distance by the protection device entrance as far as possible near place.

If it ‘s to detect the final product, then the detector should be installed as far as possible in the end of the production assembly line .

If the packing material itself includes the metal element, it’s unable to obtain the very good examination sensitivity, so you should install the metal detector in front of the packaging machine and check the products before packing.

3.   What is the products effect?

All products, when they go through electromagnetic field of the detect region, it will occur some kind of signal. This kind of signal is similar to the metal signal. This kind of signal is called the production effect.

The factor which influence production effect includes: Moisture content, fat content, temperature, acidity, salinity, direction and volume. Usually, the product which effect small can obtain the higher examination sensitivity. The suppression function of the metal detector in view of the production effect also can enhance the metal examination sensitivity.

4.   What is sensitivity?

The metal detector sensitivity defines as how small of the metal ball which is able to detected In the center of detector head, the sensitivity is also divided into "the greatest sensitivity" and " examination with product sensitivity ". The greatest sensitivity refers to the metal detector under theory condition highest sensitivity. The examination with product sensitivity is the metal highest sensitivity that detects in the practical application. Usually, the examination with product sensitivity has more practical significance.

5.Which factors will affect the sensitivity?

The metal detector sensitivity is decided by many factors. For example: The material effect, the shape of metal impurities, the size and the direction, the size of detector, as well as operation environment, the purity of the packing material  and so on.

6.   What is the ideal size of metal detector head?

The size of the head is based on the dimensions of the package. Always simulate production conditions as closely as possible, including speed, temperature, and orientation of the product.
