Several factors effect on the choice of magnetic separation machine

Dry magnetic separation machine is applicable to the following 3 mm size of the magnetite, magnetic pyrite mine,Flotation cells baking, titanium iron ore material such as wet magnetic separation, also used in coal, nonmetalliferous ore, building materials, and other materials for removing iron homework. Hongxing mine machine Co., LTD. Is specialized in the production of dry magnetic separation machine manufacturers, we dry magnetic separation machine tube surface magnetic field intensity magnetic is deep, large Angle, the strength of magnetic field stability, transmission system is stable and reliable, can significantly improve the grade of ore into the ground. So todayClassifiers, we will share your influence for dry magnetic separation JiXuan other junior index.

(1) the feeding layer thickness of: it is processed materials with the grain size and the content of magnetic particles, deal with coarse particle general feeding layer of fine grain of thick than some. Processing macrolevel ore through for the biggest to the thickness of the particles 1.5 times or so. In the treatment of the grain of the biggest particles level 4 times or so, and fine grain of material level can reach up to 10 particle thickness. Magnetic material content of raw material is not high, to be thin, through some. If the thick is at its most the magnetic particle materials by the upper pressureLimestone dryer, magnetic't absorb up and cause recovery decline. Magnetic particle content high, through to may be thick some.

(2) magnetic field intensity and working gap: it is processed materials and the grain size, magnetic discretion and operational requirements have close relations, and when the working gap between when certain magnetic poles of the magnetic field strength decided to coil of Ann circle number, circle number is not adjustment, can use to change the size of the current excitation to adjust the magnetic field strength. Deal with magnetic strong red and selected assignments suchWet magnetic separator, should use weak magnetic field, deal with magnetic magnetic weaker material and choose Saul homework, should take the field some higher. When the current must, change the size of the clearance can change not only the strength of the magnetic field, and change magnetic field gradient, reduce the gap magnetic field force has increased dramatically, generally should according to deal with the grain size to reduce its recovery to increase. Selected, it is best to the larger gap, and to increase the selectivity, to enhance the grade of the purposeSecondary cone crusher, but at the same time should be suitable enlargement of exciting current needed to guarantee the magnetic field strength.

(3) to ore speed: feed speed is in vibration slot (or belt) speed to determine. The speed of the ore it decided to grain in magnetic afraid of stay time by mechanical force, speed, the more big, the mineral grains in magnetic field stays in the shorter, the mineral grains by mechanical force by gravity and the inertia knife is given priority to, gravity is a constant, the inertial force and speed is directly proportional to the square of the. Weak magnetic mineral grains in magnetic field of magnetic force by more than gravity is not much, thereforeFlotation separator, speed beyond a certain limit because of the inertial force increases, adsorption of magnetic force will inadequacy, cause recovery is reduced. So, choose don't weak magnetic mineral using up-to-date below strong magnetic minerals to speed the ore. General in the selected, the materials of single particle is more, magnetic and strong, gives the ore speed can be increased pointChina mobile crusher, and choose, raw material contains even had body more, magnetic and weaker some, in order to improve the speed of recovery to mine should be less; Deal with fine particles, in order to mine the grain to loose, the frequency of vibration slot should be high, amplitude is small; Deal with thick bead is the opposite. Appropriate operating conditions should be based on the ore properties and to the requirements of the quality of the sorting through experiments to determine. In the treatment of the rare metal ore, raw material should keep dry narrow level to mine, is beneficial to the improvement of the index, if a wide level to mineral, because of its size by magnetic particles of large difference, but also increase the choice of election don't conditions difficult, experience prove that the classification of the screen don't, the index. A concentration plant in our country, and the grain of sieve into 2 (3) to 0.83 (20 mesh) mm and 0.83 ~ 0.2 (65 mesh) mm and 0.2 ~ 0 3 mm respectively processing, not the grading than index increased by 10%, the water in the raw material can make ore grain stick with each other, the fine particles, the more serious the degree of sticky, so the moisture of raw materials allowed at all levels are not the same. General-3 mm of raw material allows of no more than 1% of water, the fine particles. The more strict requirements.
