The ball mill is the key equipment that used to crush material, It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal processing and glass ceramics production industry, it is suitable for grinding various ores and other materials, which are widely used in mineral processing, building materials and chemical industries, and can be divided into dry and wet these two grinding ways. Small ball mill is widely used in thermal power plant pulverizing system, but its drive shaft vibration and small cone broken tooth have been plagued the production safety system, in the previous period of my factory, milling system is much troubled by these two defects, and even affect the fuel supply unit, after adjusting several times by the maintenance personnel, the effect is significant, the drive shaft vibration is lower than 0.08 mm. In recent times, the failure of the ball mill cone broken teeth is rarely heard, and now, we summary these failures as following: Specific measures: 1, the top clearance of the gear transmission assembly is one important parameter, as the procedures specified, the gap of the small cone is 7.5-8.5 mm, but in the current production, the equipment has been operated long-term, the large gear ring impact under stress is deformed, the original circular gradient gradually becomes elliptical, so its tip local clearance is even less than 6 mm, in the current process, the tip clearance should be adjusted to 8.5 – 10 mmin order to reduce the impact caused by the tip clearance, resulting in overload broken tooth. 2, the clamping force of the large ring gear enough is one of the important reasons caused the deformation. In current operation, in addition to increase the clamping force of the bolts, use the 10 mm thick steel plate to connect the ring joints together, increase the fastening plane, prevent ring deformation, guarantee the master, the driven wheel angular velocity, prevent the transmission ratio change the inertial force, resulting in fatigue fracture. 3 Fully lubricated drive shaft bearing is one important reason to ensure its smooth operation, the current traditional regular refueling manually move is used also ensure the bearings to get enough lubrication, but this could easily lead to excessive or inadequate amount of lubricant, we recommended that adopt the mechanical timing, quantitative scientific to add grease, thus ensuring moderate bearing lubrication, reducing vibration to avoid bearing wear, cage rupture and prolong life..

Washing Manganese
The vast majority of China s manganese are lean ore, ore processing must be carried out. But because most manganese ore is fine-coarse-grained or micro – fine disseminated, and there are a considerable number of high phosphate rock, iron ore and total (with) useful metal, so the beneficiation process is very difficult to conduct. The commonly used manganese ore beneficiation methods are machinery election methods (including washing, screening, re-election, high intensity magnetic separation and flotation), as well as chemical beneficiation method. First, the first step must be washing and sieving Washing is the method that use the hydraulic flushing or additional mechanical scrubbing to separate the ore and muddy. The common used gravel equipments are wash griddle, cylindrical ore washing machine and trough washing machine. Washing operations are often associated with screening, such as the ore after going through the flush cleaning or washing machine (net mine), and then be sent to the vibration sieve shaker directamente. Screening is a stand – alone operation, the obtained different particle size and grade of product are supplied for different purposes. Then, depending on the nature of the manganese ore grade, select the different beneficiation methods: Re-election (gravity dressing) Re-election only used for sorting the simple structure, coarser disseminated ore, especially suitable for the higher density of oxide ore.
The common methods are heavy media beneficiation, dressing and shaking jigging beneficiation. The process of manganese oxidation in China is generally refers to the ore is crushed to 6 – 0 mm or 10 – mm, and then grouped Enviar shaker for the further selecting. High intensity magnetic separation (magnetic dressing) Manganese ore is the weakly magnetic minerals, which can be recovered in the strong magnetic field of the magnetic field intensity magnetic separator, the generally increased manganese grade is 4% – 10%. Duo to the operation is simple, easy control, adaptability, can be used for a variety of manganese ore sorting, so in recent years they have been dominant in the manganese ore. Every new types of coarse, medium and fine-coarse-grained magnetic machine has been developed successfully. Currently, the most common manganese is a medium-coarse-grained strong magnetic separator, coarse and fine intensity magnetic separator gradually been applied. the micro – fine strong magnetic separator is still at an experimental stage. Does Magnetic flotation (flotation dressing) According to industry tests, the grinding grinding process always adopted the rod mill (rod mill) milling (ball mill) stage, and the? 2100mm 3000mm type wet grinding machine. After years of production tests, the performance is good, which is very suitable for the application of Zunyi manganese beneficiation. Magnetic flotation process successfully tested and has been applied in the production of deep marks China s manganese election has gone a major step forward.

Engine batching line unveils huge invest Pneumatic concrete batching series concrete batching plant. This batching plant using cylinder cone crusher opening batching with horizon structure can mix three kinds of four kinds of materials. The aggregate is measured by electronic weigher accumulated. The automatic batching procedure controller has the features of high accuracy, short and easy operation cycle batching batching. Such a progression is essential and inevitable for the future of the rare earth industry. Larry Ellison often expresses his thoughts on the topic. Until now the focus has been more on the concepts and horse race. But as the industry moves from theoretical to market application the rare earth miners should move toward more traditional mining and chemical processing measurements. This will require a significant expansion in the expertise and dialogue required for this industry by all participants.
But this is the way of progress. Greatness will be defined by simplicity in priorities but it will require understanding the full complexity of this budding new industry. It should be an exciting year indeed. The series concrete batching plant use belt conveyor to batch with two or three straight structure hoppers hoppers. It adopts lever electronic scale accumulated measuring and automatic control of batching process controller with the features of high accuracy, good adaptability, easy operation batching are reliable using plant.
It is hoped that more than half of the funds would be invested in the next five years Brazil is hosting the 2014 World Cup and 2016 Olympic Games and the aim is to improve infrastructure ahead of these events. A new state-run company would be created to manage future infrastructure planning, while Brazil s BNDES development bank would provide subsidised loans for the projects. 1 Separated supporting, not jointing with main tower, in this way avoiding the shaking of the main tower, making the exact weighing. 2 It set double ladder fence surface. 3 Logical material gathering equipment, avoiding material seeping en the door below. 4 The flap equipment can prevent the material return by the high block slant belt-transporting machine. 5 Add border below roller, in case of abrasion of the belt, increase belt service life.
