Electrofusion welding is the name given to resistive implant welding of thermoplastic pipes. It is one of two main techniques used for the joining of polyethylene gas and water pipes. Electrofusion welding employs fittings that are placed around the joint to be welded. Metal coils are implanted into the fittings, and electric current is run through the coils to generate heat and melt part of the pipes, forming a joint upon solidification. There are two possible fittings used in electro fusion welding: couplers and tapping tees (electrofusion saddles). Electrofusion Machines/Electrofusion Welders are used for electrofusion fittings welding. Electrofusion Fittings are a heat treatment method compared to butt fusion methods and are used to generate heat. Electrofusion welding is a type of pipe welding and polyethylene fittings, in which there are special connections that have electrical resistance wire to create welding melting temperatures. The electric current is transmitted through the electrofusion welding eequipment and through the control box to the two ends of the connection.

The hammer crusher uses a high-speed rotary hammer to impact the ore, causing the ore to break along the fragile parts such as natural cracks and joint surfaces. The figure below shows the working principle of the hammer crusher . When the ore enters the crushing chamber, it is broken by the impact of the high-speed rotating hammer. At the same time, the ore acquires kinetic energy during the impact process and is further broken by high-speed rushing to the crushing plate and the sieve strip. In addition, during the entire process, high-speed moving ore collides with each other and also produces a crushing effect.
After the ore is broken, it is discharged from the gap of the sieve bar. The ore which is larger than the gap is additionally impacted and ground on the sieve bar through the hammer until the particle size is smaller than the gap discharge machine.
