$Wet Ball Mill is the material being broken to smash the key equipment.By feeding, discharging part, turning part, a transmission of the main part.Mill widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal processing and glass ceramic production industry, for all kinds of ores and other materials may be grinding of dry or wet grinding.Ball Mill used for a long time, always more or less appear some problems.Our company based on years of experience for our customers to summarize the common problems in the ball mill. First, the ball mill anti-blocking, leak-proof basic knowledge:The anti-blocking, we first need to check the sizes of materials and material feeding amount, if the delivery volume overload, can also cause the clogging of import.For the proof, we first check whether the imported seal wear, after a period of time will have leaked, we should timely replacement of packing seal.And we have the entrance position design discharge funnel and pipes, can be timely will leak slurry discharged into the trench.Second, Wet Ball Mill liquid pump speed adjustment:Through debugging during night cyclone station pressure test, to replace the slurry pump belt pulley.In third, ball mill imports and exports effects of abrasive material size:Ball mill control into the limestone particle size, in the scope of design.General Wet Ball Mill feed size of 80% particles of less than 12mm.Regulation of entrance feed mill.General to reduce electricity consumption, mill should be routinely maintained in rated operation conditions, but sometimes as a result of a variety of reasons, the steel ball added is not timely, then according to the ball mill main motor current to reduce properly reduce the feeding quantity, to ensure the qualified pulp particle size.In fourth, the ratio of ball mill to adjust grinding material size:To maintain a reasonable ball loading and the steel ratio.Limestone is on impact, extrusion and milled into slurry, if the ball loading capacity is insufficient, fineness will be difficult to meet the requirements.Running through surveillance of ball mill main motor current to monitor the steel balls loading, if it is found that the current decreased significantly to replenish ball.Ball mill in the first operation when the mass ratio should be according to the design of steel ball.Experience shows, ball supplement in general only the diameter of the largest models, because wear different diameter ball can be included in other types of columns.Can after running for a period of time according to the steel ball wear of ball, generally running 3 months after.

$Ball Mill materials is being broken, further crush the key equipment. Mill widely used in cement, Portland products, new building materials, refractories, fertilizers, as well as black and non-ferrous metal processing industries such as the production of glass ceramics, various ores and other materials may be grinding of dry or wet grinding. Mill principle: The ball mill for the installation of horizontal rotating cylinder, outer edge of which lies Gear, two warehouses, lattice-type ball mill. Feed materials from the device into the compound empty-axis spiral uniform access to the first Mill Wharf, the warehouses have stepped liner or corrugated liner, the contents of different specifications Ball, the centrifugal force will have a rotating cylinder ball to a certain altitude sets, and have severe impact on materials and grinding role. Materials in the first positions to grinding, single-layer at the plate in the second warehouse stores, the warehouses incalculable-liner with a ball, will further polishing materials. Discharge through the grate of powder from plate to complete grinding operations. Mill structural characteristics: Feeding this machine by the Department of the Ministry of material, Rotary Department, the Department of transmission (reducer, small transmission gears, motors, electronic control), and other key components. Casting a hollow shaft, lined Looking to the future, casting a rotary gear hobbing processing, cylinder liner wear in incalculable, has good wear resistance. The smooth functioning of the machine, is reliable. R-type milling machine from the host unit structure, analysis of pipeline installation, blower, according to user needs can be fitted with a broken machine, hoist, electromagnetic Vibrating Feeder, electric motor control components. Materials are needed to crush size, the materials hoist will be sent to storage hopper, to be expected by the vibrating feeder uniform for the mainframe into Raymond Mill grinding room, as when centrifugal rotary role Roll out swinging, press the grinding part of the shovel blade materials to roll grinding and grinding Central, as Roll rolling to achieve the aim of crushing. After grinding the powder material with the circulating air blower into the analysis was conducted at the election, fine through coarse material to re-grinding, qualified powder into the air, finished with the whirlwind set of powder, the powder discharge pipe, which is refined. In Raymond Mill grinding mill indoors due to certain materials in the water, grinding, heat, air-water evaporation, and the pipeline unit interface is not well outside gas inhalation, the cycle of increased pressure to ensure that the mill under negative pressure, the increase in gas flow through the tube into the wind I precipitator was after purification into the atmosphere. Raymond Mill unit structure features: One, three-dimensional structure, small footprint, turnkey highly refined powder expected from the block of independent self-production system. 2, refined powder fineness of uniform rate of 99% on screen, it is difficult to other milling equipment available. 3, the Drive installations in confined pulley and gear box, transmission smooth, reliable operation. 4, the important components are used quality steel, wear-resistant performance of wear resistant materials are used, the whole high wear resistance, reliable operation. 5, the electrical system is centralized control, milling plant can be realized no one basic operations and maintenance. Raymond Mill unit structure features: 1, milling machines used in the process, there should be a fixed custody staff, operators must have a certain level of technology. Mill installed before the operator must conduct the necessary technical training so that they understand the principle of milling machine, familiar with the rules. 2, for the mill to normal, should develop equipment "safe operation of equipment maintenance system" can guarantee long-term security mill operation, a necessary repair tools and grease and corresponding accessories. 3, mill use for a period of time, it should repair, while Roller Mill Central blade repair and replacement of vulnerability, Roller device in use before and after the bolt nut should be carefully examined to see if it is loose, Lubricants and whether adequate. 4, Raymond Mill Roll devices around for more than 500 hours to replace Roll, roll on the roller bearing to the inner cleansing, and replace damaged parts, tools can be manually refueling pumps guns and butter.

$So far, the world's medium-speed milling machines are dry law. Hot air carrier that is, separation, sorting products. Therefore in need of a massive and complicated: medium heat generator, fans, vents Central, separator , explosion-proof system (inert gas source), dedusting system, sealing measures and it is difficult to adapt to the high moisture materials, a fine-grained access-class products in the high temperature operating equipment damage and fast, and the situation difficult to control; complete machine too tall. principle but because of movement determined by the grinding efficiency, and in electricity, the cement industry in the milling system is widely used, but no First, wet operations. Therefore, the principle of movement determined by the grinding efficiency has not been fully exploited. 2 and the Mill Although conventional campaign decided by the principle of grinding mill less than the speed, but the wet process is significantly higher than that of dry. Normally, the same conditions wet process Bian Process 30% energy saving. Because wet (water) by grinding effect, and water is the simplest, cheapest, "aids." Its will to a large extent influence the fragmentation of materials. Adsorbing water because of the solid surface (the activity of a molecule), the surface free energy and the elastic deformation can be reduced, resulting in the weakening bond together to promote and accelerate the materials crack formation and expansion, the reduction of the strength of the materials -- -- This is the famous "out Binchaer effect." The result: Wet operations for the period to achieve fineness, it can improve product yield, or yield to achieve period, the fracture particles can promote products mill will be more detailed. 3 envisaged, if the mill rate to avoid the disadvantages, while retaining the principle of movement in the rate decisions of the mill grinding efficiency at the same time allow a Wet Ball Mill with water transmission and other election materials and the simplicity of the wet efficient. designed to speed in the wet mill. its effect should be complementary. be wet grinding technology to meet a variety of needs: FGD desulfurization agents such as power plants, coal slurry preparation; while achieving energy conservation, efficiency, energy, environmental protection simple, reliable, the purpose of applicability stronger. This is the speed in the wet grinding birth of the technical background. Get Ceramic Ball Mill,Ball Mill,Beneficiation From http://www.rawmill.com$
