Product Introduction
In the casting sand treatment, magnetic separation of old sand is an important part. Magnetic separators are divided into two types: hanging magnetic separators and through-type permanent magnetic separators.
Hanging magnetic separator:
Hanging magnetic separators can separate out the strong magnetic metal material after passing through the material. They can be flexibly arranged in any place where magnetic separation is required according to the process requirements. In the casting conveyor line, the machine is arranged above the sand box after pouring, so that the iron above the sand box can be pre-magnetized. It shows its superiority when used with the old sand belt conveyor and the permanent magnetic pulley in any position.
Hanging magnetic separators consist of frame, driving mechanism, active and passive wheels, magnetic system, guiding rollers, tape tensioning device, etc.
The frame is the main connection of the whole equipment, and the driving mechanism is the moving part of the equipment, which forms a moving body with other parts to separate the magnetic metals selected by the magnetic system. The guide roller prevents the belt from deflection, and the tensioning device tightens the belt to make it move smoothly.
The magnetic system is divided into N\S two-stage structure, mainly composed of stainless steel outer frame, cover plate, bottom plate, magnetic block, etc. It has strong attraction to magnetic metal objects.
During operation, the belt travels while the magnetic separation is stationary. When the material follows the belt conveyor to the bottom of the magnetic system, the magnetic material in it is sucked, and the non-magnetic material is sent out with the belt conveyor. The magnetic material is separated from the belt surface when leaving the magnetic field range.
The hanging magnetic separator can be divided into two specifications, S995 and S997, according to the size, which can be configured according to the actual needs of the customer's production line.
Through-type permanent magnetic separator:
The through-type permanent magnetic separator is used to remove ferromagnetic inclusions such as iron beans, iron nails, and castings' flying edge burrs mixed into the old sand.
This machine is using a permanent magnet block made of a special powder metallurgy product, strontium ferrite, as a magnetic source. The magnetic poles are arranged in a circle, and the permanent magnet blocks are lined up in groups to form a NS magnetic pole group. The drum is fixed by the magnetic yoke and mandrel, and the surface of the cylinder is protected by a 4 mm thick rubber layer. The drum end cap is made of aluminum, and the magnetic separator has a stronger magnetic suction without any heat problem. It works stably and consumes less electric energy.
The magnetic groups are magnetized and glued to the yoke with epoxy resin or polyurethane. Each group is wrapped several times with a diameter of 1 mm stainless steel wire, brass wire, or polyester tape paper to avoid vibration.
During installation, pay attention not to let the magnetic blocks attract each other and collide. Assemble according to NS polarity. When moving the sprocket, the drum should rotate flexibly. When moving the shaft of the magnetic system, the magnetic system should rotate without touching the inner skin of the drum. Then install the chain and speed reducer, and connect the electricity for trial. Adjust the gap between the drum and the baffle to make the sand flow evenly across the width of the drum.
The through-type permanent magnetic separator is available in two specifications, S524III and S524II, which are suitable for 5-ton and 10-ton resin sand production lines respectively.
