(1) Sorting machine structure A China DCY type sorting machine This machine is developed by China Changchun Institute of Geology. It is divided into DCY-1 type and DCY-2 type. Electromagnet consists of three parts, the sorting channels and DC power supply components. The DC regulator uses transistor voltage regulation. [next] Japanese magnetic separation using a magnetic fluid hydrostatic nonmagnetic metal made of a schematic sorting mechanism, FIG 3, FIG. It uses a pair of permanent magnetic poles to generate a magnetic field. The magnetic field strength is 220-260kA/m, the magnetic pole angle is 30°, and the symmetry axis of the magnetic pole is inclined by 15° to the vertical axis. It is characterized in that the weight of the material fed to the feed end passes through the magnetic pole to the gap space, and the weight is automatically sunk into the magnetic pole. In the sink box at the lower part of the opening, the light object is pressed by the material feeding material, and passes through the magnetic pole to enter the floating box along the oblique direction of the density line (Fig. 4). (II) Application example A Diamond selection The test samples were taken from the Mengyin diamond mine in Shandong, China. The ore size is 0.2-0.5 mm, and the ore is first subjected to froth flotation, and the diamond is floated into a flotation concentrate having a yield of about several thousandths. This concentrate was subjected to a first magnetic separation (using a double-disc magnetic separator with a magnetic field strength of H = 1000 kA/m) to remove approximately 80% of the magnetic minerals. The non-magnetic part is sorted by two magnetic fluids to obtain a concentrate with a yield of about 5%, and then enters the second magnetic separation operation. The obtained non-magnetic part is then subjected to magnetic fluid separation to obtain a diamond concentrate, which has a purity of 95%.
Solenoid Armature makes an very important role in complete Solenoid Valve compared to other solenoid valve parts, so the quality of the armature directly related to the life of complete solenoid valve. Hereby, let me introduce how we control armature quality from character of raw material and how we produce during production.
We also called solenoid armature as solenoid valve armature, solenoid valve stem, solenoid valve core, solenoid Plunger Tube Assembly, solenoid armature tube assembly, Solenoid Armature Assembly, Electromagnetic Valve armature, etc, but all in all, the solenoid armature looks like an opener and closer even like a head in the solenoid valve.
The armature can be divided into four parts roughly, they are fixed core(who with or without shading ring depending on DC or AC voltage type), plunger tube and tube base(has option of stainless steel and brass), mobile plunger(installed with inner and outer spring, top and bottom seal).
The fixed core and movable plunger are made of high magnetic stainless iron, such as 430FR, has good performance of attraction and rust-proof. During production, we doing inspection after each procedure.
The plunger tube is made of H62 brass or seamless 304 stainless steel, the wall thickness from 0.20mm to 2.5mm available. All raw material is inspected before put them into our warehouse.
The plunger tube base is made of H59 brass or 304 stainless steel, with high performance, also we inspected each lot before put them in warehouse.
According to application requirement, choose suitable welding to connect each part, such as laser soldering, argon-arc welding, silver soldering.
The seal can be NBR, Viton, EPDM, Silicon, Teflon, etc. All can be customized as your requirement.
Except this,we also sale for Auto Drain Valve , Air Suspension Valve ,solenoid armature assembly, Forged Brass Valve .

The electromagnet includes a magnetic pole and a magnetic circuit. The magnetic pole portion is designed to have an equal magnetic force and a linear relationship between magnetic force and r. The former is called an equal magnetic pole and the latter is called a linear force pole.
The sorting trough body is made of plexiglass, its shape is consistent with the magnetic pole gap, and the material for feeding and discharging is adjustable. The separation tank structure and the separation of the ore particles in the separation tank are shown in Figures 1 and 2. 
B Foreign magnetic fluid sorting machine
Natural diamond is easily incorporated into magnetic products due to surface contamination and intrusion of magnetic impurities into the fine cracks on the surface. Therefore, the first magnetically selected non-magnetic products (actually non-magnetic and weakly magnetic products) are boiled for 30 minutes, then Enter the following operation, otherwise, a small amount of weak magnetic diamond will be discharged into the magnetic tailings in the second magnetic selection.
B is selected from gold USSR AH Berlinski (BepДИHckИЙ) magnetic fluid medium is selected from gold study of rare earth salt solution mirror, terbium and the like. The magnetic pole gap used: the lower width is 8 mm, the upper width is 75 mm, the magnetic field strength is 7500 and 8000 kA/m, respectively, and the +0.5 mm gold-bearing gold ore is selected to make the gold grade from 300 to 600 kg/ The ton is increased to 18-74 kg/ton, and the recovery rate is 07.5-98.5%. 
Welcome your any inquiry, we can produce as per your requirements.
