Cylinder is one of the main working parts of ball mill; besides the static load, cylinder also needs to withstand the impact of grinding body in the working process, therefore, it must have sufficient strength and stiffness. It requires metallic materials to make sure that the cylinder have high strength, good plasticity, good mechanical properties and processing performance to ensure the safe operation of mill shell. 1500*3000 type ball mill is the main mill produced by Hongxing Machinery; 1500*3000 type is of feed particle size less than 25mm, discharging size between 0.074-0.4mm, yield between 2-5T / H and power 75KW; The lining board is used for protecting the cylinder from the direct impact and friction from the grinding media and materials.
In a complete stone crushing plant, it is equipped with a series of crushing machines and assistant equipment, such as vibrating feeder, jaw crusher, impact crusher, cone crusher, belt conveyor and vibrating screen etc. Refractory iron ore belongs to poor fine miscellaneous ores with complex composition, there is a lot of difficulty to improve ore grade by traditional dressing recovery way, while grinding fineness is a key factor. For example, Qidong iron ore asks grinding fineness -38 um ≥ 95% ~ 98%, Shanxi Yuanjiacun iron ore asks -38 um ≥ 95%, as well as Shizhuyuan solid non-ferrous metal ore and Ruyang molybdenum mine ask grinding fineness in tailings recovery – 38um ≥ 95%. Therefore, regrinding or fine grinding equipment is essential. Many of our mining industry produce iron ore by ordinary horizontal ball mill, while the ordinary horizontal ball mill has low efficiency, the product particle size and mineral monomer dissociation cannot reach requirement.
The grinding fineness -38 um can reach 95.10%, iron concentrate grade reach 65.00%, making significant economic benefits. Golden is wrapped in pyrite, existing in the form of microscopic gold, sub-microscopic gold or solid solution, and insolubly extracted. Vertical screw mixing mill strongly destruct material interface layer in the process of leaching while pulverizing thus speeding up the chemical reaction rate and improving the leaching rate. It has been successfully applied in many gold enterprises. Meanwhile, we can make use of different forms of liner to adjust the motion state of the grinding body to enhance the crushing effect on materials so as to improve the grinding efficiency, increase production and reduce metal consumption.
