During the magnetic separation process of the magnetic separator, the magnetic drum skin will be constantly impacted by granular iron ore below 0~15mm, causing serious wear and tear. The phenomenon of magnetic drum skin wear often occurs in the industry. Therefore, the magnetic drum skin of the magnetic separator needs to be strengthened for protection. Test data shows that once the skin of the magnetic drum of the magnetic separator is worn and leaked, the slurry enters the magnetic drum and is adsorbed on the surface of the magnetic system, causing locking between the drum skin and the magnetic system, or the slurry enters the bearings, causing damage to the bearings and destroying the entire equipment. Protection Tips: First of all, in the selected magnetic separator, the magnetic drum must be well protected. The drum skin can be wrapped with PVC coating and sprayed with a wear-resistant layer of polyurethane elastomer. * * Improved barrel skin service life. Polyurethane elastomer spraying uses high-strength, wear-resistant and corrosion-resistant materials - spray-type polyurethane elastomer. It can withstand the erosion of acid, alkali, oil, water and other media with a pH value of 3-11. It has excellent anti-corrosion properties and has the characteristics of high resistance to salt spray corrosion and good frost resistance. ； And it has the advantages of high toughness, easy construction, hardening, high strength, good plasticity, resistance to bending fatigue and contact fatigue, high dynamic load performance, not prone to bonding, high strength and wear resistance, corrosion resistance, self-lubricating, etc. At the same time, spray-type polyurethane elastomer is not easy to age, has low friction, and has a wide hardness range (from Shore A30 to Shore D90, it can maintain high elasticity). Secondly, to fix the magnetic system, you can choose to use stainless steel plates to wrap the magnetic system. The joints at both ends of the stainless steel plate are clamped with thin plates and fixed with bolts. Use bolts to connect and adjust the tension. This not only has little impact on the magnetic field on the surface of the magnetic system, but also has a strong enough wrapping and tightening force on the magnetic system, and the effect is remarkable.
