Weak-magnetic material recovering machine

Abstract

The invention discloses a weak-magnetic material recovering machine, which is characterized in that: the machine comprises a frame; a material storage is arranged above the frame; a vibration feeding apparatus is arranged in the frame below the material storage; a delivering belt tensioned by a magnetic roller and a redirecting roller is arranged below the vibration feeding apparatus; the rotation speed of the magnetic roller is changed through a variable-frequency and variable-speed motor connected therewith; a plurality of discharging hoppers are arranged below the delivering belt; and the magnetic roller and the redirecting roller are respectively arranged on two sides of the crossbeam with a ball bearing with an eccentric sleeve and an adjusting seat. The magnetic roller is formed by round disks manufactured by using a neodymium-iron-boron rare earth permanent magnetic material; a pole piece of soft iron is adopted between two round disks with a same polarity; the two round disks are alternately superposed, and are compressed to form a whole. According to the invention, precious weak-magnetic particles in mixed particles can be separated from other non-magnetic particles. A recovery rate is high, the purity is high, and a high economic benefit can be provided.

Description

technical field [0001] The invention relates to material sorting equipment, in particular to a weak magnetic material recovery machine for sorting weak magnetic particles from other non-magnetic particles. Background technique [0002] The sorting of magnetic materials is relatively common in the prior art. For example, Chinese patent 202052622U discloses a quick sorting device for steel sand, which includes a frame with a discharge port at the bottom, and a fixed plate on the upper part of the frame. A fast motor is arranged on the board, and a belt pulley is arranged at the output end of the fast motor. Magnetic separation rollers are arranged in the frame, and the magnetic separation rollers are arranged on support seats on both sides of the frame through a rotating shaft. One side is provided with a transmission disc, and the transmission disc and the belt pulley are driven by a belt, and a material inlet is provided on the fixed plate above the magnetic separation rolle...

Problems solved by technology

After the casting falls out, the chrome ore sand is mixed with ordinary silica sand and cannot be recycled, resulting in waste of resources and economic losses

At present, the chrome ore used in my country mainly depends on imports, and the price is expensive. The average price is about RMB4500 / t, and there is an upward trend. Therefore, the recovery of chrome ore has become an urgent issue in the foundry industry.
