Short introduction                                                                    

This type of Magnetic separator is mainly used to separator the Magnetic .  Pyrrhotite , Calcined Ore sized 0-3 mm . It can also remove the iron from construction materials . The magnets are made by high quality Ferrite and rare earth materials . The surface magnetic force of the cylinder can rare reach 100-600 mT . To meet the customer is need , we have made 3 types of magnetic separators , Downstream types 6mm, Counter-current type ≤ 1.5mm , Half counter-current≤0.5mm

 Vacuum Filter                                                                             Vacuum filter is based on the vacuum negative pressure as driving force to realize solid-liquid separation equipment in the structure, the filteringsection along the horizontal direction arrangement, can finish filtering,washing, dry and cloth regeneration operation is continuous. Rubber belt filter has high filtering efficiency, large production capacity, good washing effect, low moisture of filter cake, flexible operation, low maintenance cost. Rubber band filter can be solid-liquid separation is widely used in the field of metallurgy, mines, chemical industry, papermaking, food,pharmaceutical, environmental protection etc., especially gypsum dehydration in flue gas desulfurization (FGD) has a good application.

Filter is the use of porous filter media, interception of solid particles in liquid and solid particles in the mixture, and the realization of solid, liquid separation equipment. Filter is widely used in chemical, petroleum, pharmaceutical, light industry, food, mineral processing,coal and water treatment etc..

Chinese ancient already filtering has been applied in production, two hundred BC have beenmade of plant fiber paper. In 105 ad, Cai Lun improved his swing in the papermaking process,dense in papermaking process of plant fiber pulp fine bamboo, water bamboo slot filtration, a thin layer of wet pulp stay on the bamboo surface, dry the paper.

The first filter is gravity filtration, then the pressure filtration, the filtration rate increases, andthe vacuum filter. Rotary drum vacuum filter at the beginning of the twentieth Century the invention realizes continuous filtering operation. Since then, various types of appearedcontinuous filter.

Working principle                                                                      

Vacuum filter in the filtrate outlet pressure as the impetus of formation. This filter is divided into intermittent operation and continuous operation two. Vacuum filter can filter the intermittent operation of the suspension with different concentration, the continuous operation of the vacuum filter is suitable for thick suspension liquid containing solid particles more filter.

Filter for intermittent operation can realize the automatic operation and development, more and more large filter area. In order to get the low moisture content of filter residue, filtermechanical press has been developed.

The container with filter media is divided into the upper, lower, constitutes a simple filter.Suspension is added into the lower chamber, the filtrate through filter media is under pressure, solid particles are trapped in the filter medium surface to form a residue (or cake).

Filtration residue layer surface deposit thickening filtration process, the liquid through the residue layer resistance will be increased, the filtration rate decreases. When the filter chamber filled with the residue or the filtration rate is too small, to stop filtering, removingresidue, so that the filter media regeneration, to complete a filter cycle.

The liquid through the filter residue and filter media must overcome the resistance, so there must be a pressure difference on both sides of the filter media, which is the driving force for filtration. Increasing the pressure difference can accelerate the filter, but the compressiondeformation of the particles in the large pressure difference is easy to plug the porous filter media, filter but slow.

Suspension filtration residue layer filter, filter and filter screen in three ways. Cake filtration is refers in the filtering phase, the initial formation of cake layer, then, the residue layer plays a major role in filtering, this big, small particles are trapped deep bed filtration is the filtration medium; the thicker, less solid particles suspension containing particles, and smaller than thefilter medium pore, filtering, after being adsorbed on the particles into the pores of the filter;filtration is the filtration of the solid particles are larger than the pore filter media, filtrationmedium adsorption of solid particles, such as rotary filter screen to filter the coarse impuritiesin sewage.
