The GJT-B series metal detector is a state-of-the-art solution designed for detecting metallic contaminants in conveyor belt systems. This product incorporates advanced digital phase shifting and detection technologies, ensuring high sensitivity and strong resistance to interference. It is widely used in industries such as thermal power, cement, paper, mining, forestry, environmental protection, and construction materials.
Working Principle:
When a metal object enters the electromagnetic field of the sensor, it generates changing signals that the metal detector can identify. These signals are processed electronically, and the system then activates the control device (such as an electromagnet or motor switch) to remove the harmful metal from the conveyor belt.
Timing Function: The electric relay will be delayed after activation, with a time range of 1 to 10 seconds.
Output Control: One pair of the electric relay's contact points is open, while the other pair is closed.

1. Composition: Tinplate is made of low-carbon steel that is coated with a thin layer of tin, usually between 0.1 and 1.5 microns thick. The steel is typically rolled into thin sheets and then coated with tin using an electrolytic process.
2. Applications: Tinplate is widely used in the food and beverage industry for making cans, as well as in the packaging of other products. It is also used in the production of toys, decorative items, and other consumer goods.
3. Advantages: Tinplate has several advantages over other materials. It is strong, durable, and can be formed into a wide range of shapes. It is also resistant to corrosion and can be easily cleaned and sterilized, making it ideal for use in the food and beverage industry.
4. Recycling: Tinplate is highly recyclable and can be reused many times. When tinplate is recycled, the steel is separated from the tin coating and can be melted down and used to make new products, while the tin is typically reused in the production of new tinplate.
5. Sustainability: Tinplate is considered a sustainable packaging material because it is recyclable and has a low carbon footprint. Additionally, the use of tinplate can help to reduce food waste by extending the shelf life of packaged products.
6. Variations: Tinplate can come in different grades, or thicknesses, depending on the application. It canalso be coated with other materials, such as lacquer or polymer, to provide additional protection or to improve its appearance.
7. History: Tinplate has been in use since the 17th century, when it was first used to make decorative objects. It became more widely used in the 19th century with the development of the canning industry. Today, tinplate is a ubiquitous material that is used in many different industries around the world.
8. Production: Tinplate is typically produced from a coil of steel that is fed through a series of rollers to create a thin, flat sheet. The sheet is then cleaned and coated with tin using an electrolytic process, in which an electric current is used to deposit the tin onto the surface of the steel.
9. Quality control: Quality control is an important part of the production process for tinplate, as even small defects or variations in thickness can impact the performance of the material. Tinplate is typically inspected using a variety of techniques, including visual inspection, measurement of thickness and coating weight, and testing for corrosion resistance.
10. Future: The use of tinplate is expected to continue to grow in the coming years, driven by the demand for sustainable packaging materials and the increasing use of canned food and beverages around the world. However, there are also efforts underway to develop alternative materials that can provide similar performance and sustainability benefits.
