As we all know, sand is the essential material for construction industry, its quality has an important influence on the quality of construction works. Now, the quality of nature sand is declining due to the disorderly exploitation and the depletion of resources. Instead, the project construction are more and more strict in the sand quality. ultrafine mill is a kind of sand washing equipment, in the washing process, the stones, mud and other impurities will be greatly reduced, the quality of sand will be significantly improved. As the professional manufacture of ultrafine mill, Henan SBM Mining Machinery will talk about the main factors affecting the production of ultrafine mill based on our years of experience: First, the content of sand soil The original sand quality will be the decisive factors affecting the output of sand washing. The quantity of mud, stone, shell and other impurities, the size of particles will affect the output of ultrafine mill. Second, the proficiency of operation The operators will also affect the production of sand washing. It is necessary to train the operators before using the ultrafine mill. The operator must understand the working principle, performance characteristics and other precautions. Third, the maintenance level of equipment ultrafine mill should be regularly maintained so as to maintain a good working condition, which is the premise of guaranteeing production. Fourth, the quality of ultrafine mill Any equipments' operation result is closely related to the quality of equipment itself. As is well known, the same product may bring us different experience and value for the different quality. The above is the brief introduction of several factors affecting the production of ultrafine mill. It is my great pleasure if it is helpful for you. If you have any problems, please contact us. Henan SBM Mining Machinery experts will serve you faithfully!

The board hammer abrasion of ultrafine mill only can be found on the side of contacting materials. When the rotor operates at normal speed, the charge-in materials will fall onto the surface of board hammer (attack side), and the back and flank side of the board hammer is not worn. And even the contacting side is rarely worn. Besides, the bottom of the grinding rod is also very easy to replace. The metal utilization of ultrafine mill board hammer can be as high as 45% -48%. However, that of usage of hammer crusher is just 25% or less. Because the hammer head of hammer crusher is in overhanging state. The abrasion is occurred on above side, front, rear side and flank side. Compared to board hammer, the hammer crusher is worn more serious. Furthermore, the rotor may also suffer abrasion. Once the bottom screen of hammer crusher wear too seriously, the grille should be replaced completely. And replacement is more complicated. There are only six board hammer installing on the rotor of ultrafine mill, so that the board hammer can be replaced easily with tools. The replacement of a board hammer just spends a shift time. And the bottom grinding rob replacement only takes several minutes. That greatly reduces the time of repairmen and cost of maintenance. However, hammer crusher has over 100 hammer heads. It spends a lot of time and labor source to replace a hammer. And the costs of repair and maintenance is higher. Moreover, the bottom screen replacement is extremely complicated. Based on years of experience, PF Series ultrafine mill has been developed by Zenith Mining Machinery Company. It is a kind of broken machine making use of impact energy to break the materials. When operating, the rotor will high-speed rotation driven by the motor. As the material come into the interaction region, they were broken by attacking with the plate hammer. And then the materials were thrown to the counter-attack on the device for crushing again. Finally, the materials bounced back into the interaction region to re-broken. This process is repeated and materials size from big to small through repeated broken in the first, second and third impact chamber until the material is broken to the desired particle size and out of the discharge port. Adjust the gap between the frame and the rotor can change the material particle and shape. Stone falls directly into the high-speed rotation of the turntable from the upper part of the machine; under high-speed centrifugal force, stone shunts around the turntable with umbrella shape at high-speed. Under the collision with each other, stone will friction, grinding many times. Finally, finished products fall straight from the lower part of the discharge. Thus form a closed loop several times to reach the required particle size by sieving device control.

There are many precision couplings in the hydraulic system of ore milling equipment some with damping hole, some with crack. If solid impurities invade the crushing cavity, the precision couplings will be strained, and the oil pipes will be blocked, thus endangering the reliable operation of hydraulic system. Generally, solid impurities will invade the hydraulic system if the oil is not clean enough or if the instrument is dirty or the maintenance is bad. The desquamation of hydraulic components can also cause the invasion. Clean hydraulic oil is the life of hydraulic system, which is as important as the heart to a person. When filling oil, operators should filter it in advance. The instrument must be reliable and clean. The filter cannot be eliminated for improving the filling speed. Operators should use clean gloves and labor suit in case solid impurities or fiber impurities fall to the oil. When implementing maintenance to the hydraulic system, people need to disassemble the lid, the filter cover, the inspection hole and the hydraulic pipes. The oil pipes should avoid being exposed to dust. In addition, the dismantled parts must be cleaned before being opened. When it comes to the cleaning cloth and iron hammer, much detailed information needs to be kept in mind. The cloth should be of non-fiber material and the hammer should be equipped with rubber to avoid abrasion. All the hydraulic components and pipes need careful cleaning and they need to be assembled after being dried with high-pressure blast. Authentic filter should be chosen for the components. When changing oil, it would be better to clean the filter at the same time. Before installing filter, professional cleaning material should be used to clean the impurities at the bottom. It should be noticed that: the cleaning oil should be matched with the hydraulic system with temperature between 45-80 large amount of oil can take away part of impurities in the system. The hydraulic system should be cleaned more than three times. After cleaning, the oil needs to be released from the system while the temperature is high. Then the filter needs to be cleaned, after which the oil can be refilled.

High-frequency vibration fine screen is called construction waste crusher for short, and it is a type of classifying machine used in ore beneficiation plants. Relying on the different width of the grating gap of the screen, it can classify the materials according to the granularity. Application Ranges of construction waste crusher The construction waste crusher is mainly used for classifying various hard materials with weak corrosively. The water content of the materials to be classified should be below 15%, and the compression strength should not exceed 100MPa. It is suitable for the wet and dry screening, classifying, dewatering and disliking of various materials in such industries as ore dressing, chemistry, coal mining, food, brick making, pharmacy, fertilizer and paper making industry. In addition, the construction waste crusher can also be used in sand making production line, stone crushing production line as well as ore beneficiation line. Structure and Advantages of construction waste crusher The construction waste crusher is composed of exciter, pulp distributor, screen reel, rack, hanging spring and screen net. SBM construction waste crusher has high working efficiency, small amplitude and high screening frequency. Its screening principle is different from that of common screening equipment. The construction waste crusher has high frequency, so that it breaks the tension of the surface of the pulp and the high-speed oscillation of the final particles on the screen net, accelerates the separation of the useful minerals with big density and increases the probability of the materials smaller than the separating granularity contacting with the screen. In this way, good separating condition will be created, so that the materials smaller than the separating granularity, especially the materials with big proportion and pulp can go through the screen.

Construction waste crusher is a single-stage crushing machine that directly breaks the materials with the biggest granularity of 600-1800mm into materials with the granularity of 25mm or below. It is suitable for crushing medium hard materials in such industrial departments such as cement, chemistry, power station and metallurgy and for medium and fine crushing limestone, furnace clinker, coke and coal. Types of construction waste crusher: The construction waste crusher is composed by the machine box, rotor, and hammer, impacting plate and screening plate. The hammer crusher machine can be divided into many types, such as single-stage construction waste crusher, highly efficient construction waste crusher, vertical hammering machine, irreversible hammer crusher machine. If the hammer of the hammer crusher machine is changed to be a steel ring coal crushing machine, then the machine will become a variant. Unique Characteristics of Hammer Crusher Machine: 1. The working hammer adopts new technology so that it is highly resistant to abrasion and impacting. 2. The particle granularity of the materials produced by the hammering machine can be adjusted according to the requirements of the customer. 3. The structure of the construction waste crusher is sealed up so that there is no powder pollution inside the crushing workshop and no ash leakage in the machine. 4. The whole machine is beautiful in the modeling and compact in the structure, and there is few easy wearing spare parts, and what is more, the repair and maintenance process is very easy and convenient, so that this machine is an ideal updating product. Working Principle of construction waste crusher: The hammering machine mainly crushes materials by relying on the impacting effect. The generally crushing process goes like this: after going into the crushing machine, the materials will be impacted and crushed by the hammer with high rotary speed, and the materials crushed will gain energy motion from the hammer and rush to the baffle and grate bar with high rate, and at the same time, the materials will also impact with each other. After being crushed for many times, the materials that are smaller than the gap between the grate bar will be discharged from the gap, and the bigger materials will impacted, ground and pressed by the hammer on the grate bar until the desired granularity is satisfied.

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 ultrafine mill 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. Vertical screw mixing mill is regrinding and ultrafine mill with the most promising development prospect, high energy efficiency and fine granularity. In addition, because of its simple structure and convenient operation and maintenance, it is widely used in the industrial production of gold ore, nonferrous metal ore, metal ore and magnetic materials. Shizhuyuan non-ferrous metal ore and iron ore concentrate regrinding adopted the ordinary horizontal ball mill for many years, the grinding fineness was -44 um and iron grade was in 53% to 55%--far away from the requirement. After several tests, they have adopted Zenith vertical screw mixing ball mill for non-ferrous metal ore and iron ore concentrate grinding since 2005. 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.
