Screening and feeding is an important link in the mine crushing system, and it plays an important role in the process of primary feeding and screening, uniform feeding in the transfer bin, and finished aggregate screening. Meilan organized a R&D technical team according to the crushing needs of mines. Through motion trajectory analysis, three-dimensional simulation, and actual application environment, they have successively developed: MF series fixed shaft vibrating screen, MA/K series vibrating screen And MGS series vibrating feeder, MGD series vibrating feeder, MGB series silo feeder. Meilan's screening and feeding series products undoubtedly represent the most advanced screening and feeding technology and manufacturing process level today. The Meilan's screening and feeding series products with both technological strength and attractive appearance are innovative. The modular design, combined with the finite element dynamic analysis frame structure, combined with high vibration intensity, fully guarantees the high-yield, high-efficiency and low-cost of the equipment during the screening and feeding operations. The whole body of the side panel of the fuselage is precisely cut by laser, and it is precision processed by CNC machine tools. At the same time, it is processed by physical bending process to prevent the hidden danger of cracking. After tempering, the efficient shot blasting process creates a smooth and smooth appearance. Every part of the screening and feeding series products is shining with quality.
MF series fixed shaft circular vibrating screen
1. The upper and lower flanges of the integrated alloy wear-resistant steel plate are used to make the side panels of the screen box, without welding, to avoid stress concentration, and with high-efficiency shot blasting, it is durable and does not crack.
2. It adopts modular frame beam design and imported rivets, which is strong and durable without deformation.
3. Constant amplitude, stable vibration, and the best installation angle of 20 degrees, effectively improving the screening efficiency by 40%-75%.
4. The gantry milling machining center processes the bearing holes and the spindle is fixed, which avoids the resonance between the screen groups, and solves the stubborn problem of the screen box cracking caused by the diagonal vibration of the screen box, and prolongs the service life of the vibrating screen.
5. The special curved screen surface design makes the screening cleaner and a variety of material choices to meet the needs of customers in different working conditions.
6. The overall bottom steel frame and the screen box are connected in a special way, which is convenient for the overall transportation of the vibrating screen, and can be hoisted as a whole at the construction site, which is convenient and quick to install.
MA/MK series circular vibrating screen
1. The biaxial vibration exciter has strong excitation force and better screening effect.
2. Thin oil lubrication, longer bearing life and low maintenance rate.
3. The upper and lower edges of the integrated alloy wear-resistant steel plate are folded to make the side plates of the screen box, without welding, to avoid stress concentration, and to improve the precision with the finishing process, and the high-efficiency shot blasting treatment is durable and does not crack.
4. Adopting modular frame beam design, imported rivets, sturdy and durable without deformation.
MS series three-axis horizontal screen
1. The upper and lower edges of the alloy wear-resistant steel plate are folded to make the side plates of the screen box, without welding, to avoid stress concentration, and durable without cracking.
2. Adopting modular frame beam design, imported rivet riveting, shot blasting treatment, strong and durable without deformation.
3. Horizontal placement, low installation height, stable screening, thin oil lubrication, and the integrated design of the bearing box completely solves the problem of oil leakage in the oil tank. The bearing life is longer and the maintenance rate is effectively reduced.
4. The screen box performs elliptical motion, and the three-axis vibration force is strong, and the screening is cleaner.
5. The bore diameter of the bearing is processed by a gantry milling lathe to minimize errors and make the bearing run more smoothly. The vibration angle and amplitude can be adjusted to ensure higher screening efficiency.
6. Vibration absorbing technology is adopted to avoid lateral shaking caused by resonance when starting and stopping, and protect the vibrating screen and infrastructure.
MGD vibrating feeder
1. The side plate is made of alloy wear-resistant steel plate, which is durable and does not crack.
2. Modular frame beam design, convenient for disassembly, transportation and assembly, overall shot blasting treatment, a full set of paint technology, to ensure that the equipment is as new for a long time.
3. The trough is welded by low-alloy plates. After tempering, the brittleness of the product is eliminated, and the toughness of the product is increased, which guarantees the hardness of the product and increases the elasticity of the product. Manganese steel bottom guards, side guards and grate bars are installed in the trough, which is resistant to impact and has a long wear life.
MGS vibrating feeder
1. The tank and bearing are designed according to heavy working conditions, with large processing capacity and strong impact resistance.
2. The upper and lower edges of the alloy wear-resistant steel plate are folded to make the side panels of the screen box. After the trough is welded, it is tempered at 600 degrees to avoid the welding stress concentration, and it is durable without cracking.
3. The 42CrMo material is used, and the forgings are heat treated to ensure the durability of the shaft; the feed box and the spring seat adopt a pin structure, which is convenient to change the installation angle of the feeder (the factory default angle is 5 degrees).
MGB silo feeder
1. The MGB series silo feeder uses a vibrating motor as the excitation source, with low noise, low power consumption, good adjustment performance, and no punching.
2. Stable vibration, reliable work, long life; adjustable excitation force, flow can be changed at any time, adjustment is convenient and stable.
3. Simple structure, light weight, small size, convenient maintenance, tempering and shot blasting, the fuselage is integrated, sturdy and durable.
