  • Raymond Mill's production bottlenecks are mainly in which part?
    First of all, we need to understand the production process of raymond mill: grinding process and winnowing process.
    The production bottleneck of the grinding process is mainly the blade angle problem, the sealing problem of the roller assembly, and the wearing degree of the wearing parts.
    First of all, the angle of Raymond's blade has played a vital role, and some Raymond Mill manufacturers are apt to ignore this problem. Raymond's blade lift position is high and low, making the blade shovel The starting material cannot be accurately delivered to the grinding position, which greatly affects the production of Raymond Mill.
    Secondly, the sealing problem of the roller assembly, which is directly related to the use of Raymond Mill manufacturers can normally use the problem of normal production. If Raymond Grinding Roller Assembly cannot effectively seal, then the inside of the assembly is very easy to enter into powder. After the powder is poured in, the total achievement of raymond mill is easy to be broken, and often it will be broken, which will bring about normal production. Serious trouble. The latest assembly developed by Xinyuan Machinery adopts the principle similar to the mechanical seal, adopts multiple oil seals and progressive zero-gap sealing, and the effect is unanimously recognized by the society.
    The last is the degree of wear of the wearing parts. If the wearing parts (ie grinding rollers and grinding rings) are made of ordinary carbon steel, then they will wear off quickly, which will increase the production cost of Raymond Mill manufacturers. The maintenance rate will also increase. It is recommended that customers use high-manganese steel Raymond mill rolls and grinding rings.

  • Which type of sand making equipment is suitable for light calcium carbonate crushing? Light calcium carbonate is produced by chemical processing. Because its settling volume (2.4-2.8 mL/g) is greater than mechanically produced ground calcium carbonate sediment (1.1-1.9 mL/g), it is referred to as light calcium carbonate. SBM's new type of sand making machine is a new type of high efficiency, widely used in the crushing and crushing of various raw materials such as rock, ore, cement clinker, and refractory materials.

  • As we all know, things are two-sided. The same is true for construction waste. On the one hand, it shares the same land with ordinary household waste, polluting the environment, and bringing many changes to people’s lives. However, on the other hand, construction waste can be used as a resource to make it become It can be used as a recycled material for roads, buildings, etc.
    The term "construction waste" refers to the collective name of the waste muck, waste concrete, masonry, and other solid wastes that people produce in the production activities such as demolition, construction, and renovation. The amount of construction waste crusher in China today accounts for 30%-40% of the total municipal construction waste, and the vast majority of them have not yet been disposed of by the construction unit and transported to the suburbs for open storage and landfill, which not only consumes a lot of expropriation. Land fees, garbage clearance, etc., and problems such as remains and dust generated during clearing, transportation and dumping can also cause serious environmental pollution.

  • Buying a good stone crushing equipment not only pays attention to the crusher price at the time of purchase, but also the daily maintenance work after purchase, which is also the key to greatly increase the service life of the equipment. In the daily operation of the equipment, good operating habits and post-operation maintenance work can maximize the service life of the crusher accessories. Below to explain to you about the daily maintenance of crusher parts related issues.
    1. First, when crushing the material, it is necessary to select suitable material crushing according to the crusher's performance. If the material of the broken material is too soft or too hard, it will wear on the parts of the crusher. Especially in the sand stone production line, the materials that need to be broken are more complicated, so it should pay more attention to this problem, when selecting the crusher accessories, To be detailed according to the characteristics of the material.
    2. Before the material is broken, it is necessary to conduct a simple screening on the material to prevent the content of fine powder in the material to be broken from being too high. Because if there is too much fine powder in the material, it will affect the conveying speed in the crushing process, because the fine powder will adhere to the conveyor belt, which leads to the material in and out of material speed, reducing the production efficiency, so before crushing the material Simple screening can be done.
    3, if you meet the need to crush the viscosity of the material, humidity, temperature, etc., then you need to select different crusher equipment according to the specific circumstances. In the beneficiation equipment, different crusher models are developed for different material characteristics. Therefore, selecting different crusher types can effectively reduce the number of components according to the size of the material moisture content, the temperature difference of the material, and the viscosity of the material. The degree of wear is also the key to improving the service life of the equipment.
    4, in the selection of crusher equipment, can not just look at the overall machine performance, appearance, price, etc., the most important thing is to look at the quality of each component of the device. To choose a good crusher, we must choose high-quality, high wear-resistant accessories, so as to play the maximum utilization rate of the crusher.
    5. After the material is broken, the particle size of the finished product will also affect the service life of the crusher. The finer the particle size of the material required for crushing, the greater the wear on the crusher parts, because the finer the particle size of the material, the more friction between the material and the fitting, and therefore the greater the wear, which also affects the use of the crusher. The key to life.

  • Efficient centrifugal impact sand making machine has a wide range of applications. The working principle is that the material falls vertically into the high-speed rotating impeller from the upper part of the machine. Under the action of high-speed centrifugal force, it collides with the material around the impeller and then enters into the impeller and the casing. In the powerful vortex, they bumped and rubbed against each other until they were crushed. The material is discharged from the discharge port at the bottom of the sand making machine, and then the material is controlled by the screening equipment to achieve the finished product particle size that meets the requirements.
    One of the biggest problems faced during the operation of the sand making machine is that the operation efficiency is low. How to improve the efficiency of the sand making machine has become the primary concern of SBM heavy industry. The operation efficiency of the sand making equipment is affected by many factors. SBM Heavy Industry Remind you to pay attention to the following aspects:
    First of all, to understand the sand making machine in the entire sand production line process, the first is feeding, the second is the coarse broken jaw crusher, and the third is a high efficiency centrifugal impact sand making machine. The sand making machine is used as a rough breaking device for crushing hard materials such as ore, and has the characteristics of large crushing ratio, high output, uniform particle size, simple structure, convenient maintenance, and low production cost.
    Secondly, the more mud or fine-grained grade in the feed of sand and gravel production lines, the greater the viscosity of the ore slurry, the smaller the settling velocity of the ore particles in the pulp, and the coarser the particle size of the overflow product; in this case, In order to ensure that the desired overflow fineness is achieved, additional water may be appropriately increased to reduce the slurry concentration.
    The high-efficiency centrifugal impact sand-making machine has fine granular requirements for sand-making materials, and the requirements for its grain type and grain-size are very strict. The reason is that cuboidal sand has an interlocking effect because of its angular shape, and the continuous gradation of sand can greatly reduce the gap. At the same time, cubical sand occupies a larger surface area than round sand. Sticking asphalt and materials or cement and materials together reduces the possibility of displacement.
    When the sand making machine breaks into the non-crushable stone in the crushing chamber, the rear thrust plate is used as a safety component of the sand making machine for maintaining the important parts of the equipment from being damaged.
    The high-efficiency centrifugal impact sand making machine produced by SBM is a very simple and efficient sand making equipment. In the daily production, as long as many observations and researches, we understand the working principle of the high-efficiency centrifugal impact sand making machine and can give you Bring unexpected benefits.

  • Dust problem, in the dry ultrafine mill, there are more or less dust problems, feed port, discharge port and the fan seal, due to the fine powder size, can easily fly out from a bad seal. The solution is to use a negative pressure system as far as possible, using good crushing equipment with fine sealing and fine grading equipment. If necessary, install a dust removal system in the crushing workshop to ensure the clean production of the workshop. This is a problem for pigments, dyes, fiber powders and poisons. Powder is extremely important.
    Ultra-fine grinding, there are some vibration and noise, especially for vibration mill, ball mill, noise up to 120dB, if necessary, set up a special isolation box or isolation room, isolation grinding equipment. Some low-noise ultra fine grinding mills have been developed, such as tower mills, agitator mills, etc., which can be used preferentially. However, the ultra-fine grinding environment is harsh, and different industry requirements are not the same. In industries such as mining, refractory materials, and coal industries, the conditions are relatively poor, and there is a need for cleanliness in the pharmaceutical and food industries. In any case, reducing noise is imperative.
    Superfine wet comminution, regardless of the process used, especially fine ceramics, powder metallurgy, inorganic non-metallic materials and other industries, the application of water, oil or alcohol can be recycled. This requires the filtration of water or oil after dehydration (or oil), and it can be recycled in applications where it is ensured that the raw materials are not contaminated.
    Ultrafine grinding is a unit operation in many industrial productions, and environmental protection issues should be comprehensively considered in specific working conditions.

  • Where does Raymond noise come from?DateWed May 30, 2018 6:41 am

    Raymond Machine is an ultra-fine grinding device for ore grinding by rolling mill with suspended roller. It can be fed into powder once at a time. The noise of raymond mill is very small during normal production and operation. When Raymond machines are noisy, they should check which parts have problems. After the Raymond machine is installed and commissioned, in addition to adding oil once a day, the screws are tightened again for a few days to ensure stable operation of the equipment. When feeding, be sure not to cause the Raymond machine equipment to be evenly blocked. If the working chamber is blocked, first stop the feeding. Use the wind force of the fan to see if the material can be blown out. If you can't blow it out, you should observe the host below. Open the door or open the large observation door to clear some of the material and then turn it on again. Usually when you are refueling, you should observe a lot to see if there are screws or iron pieces in the host. If there is timely cleaning out, the presence of screw iron pieces will also appear very loud. Raymond noise may also be the fan is not fixed, check the looseness of the screw, the fan if you replace the fan must be re-corrected dynamic balance and static balance to ensure the stability of the fan operation. The problem of noise in Raymond's machine is actually a very good solution. First, determine where the noise comes from, and then identify the problem one by one and give it a solution. Normally, it is necessary to observe more during maintenance and refueling. The maintenance should be done for a period of time. The fixing and fixing can ensure the continuous and stable operation of the equipment without any breakdown. It is like to treat your equipment like a car. It is for you to make money. Yes, we must understand and understand the truth, and we can usually pay more attention to it.

  • The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are used extensively as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and burned into quicklime. Lime has quicklime and hydrated lime. The main component of quicklime is CaO, which is generally blocky, pure white, and pale gray or pale yellow when containing impurities. Lime absorbs moisture or adds water to become slaked lime. Slaked lime is also called ripe lime. Its main component is Ca(OH)2. The hydrated lime is formulated with lime slurry, lime paste, lime mortar, etc., and used as a coating material and a tile adhesive. Limestone is an extremely valuable resource. Limestone is a trade name for limestone as a mineral raw material. Limestone is widely used in the history of human civilization because of its wide distribution and easy accessibility in the natural world.
    The wide-spread use of limestone focuses on the efficiency and quality of Ore Milling Equipment. As the largest milling machine production base in China, Shanghai Keli Rike Machinery Co., Ltd. has been dedicated to the upgrading of the milling machine, because Shanghai Kelilik company has a strong R & D department and elite personnel, through continuous development And enterprising, has successfully developed a variety of models, fashionable and affordable new generation of Ore Milling Equipment products, and mine crusher series of equipment and other equipment to meet different customer requirements, quality product quality and efficient after-sales service, The customers all praised.

  • Raymond Mill is a kind of grinding equipment imported from abroad. The raymond mill is widely used in non-inflammable and explosive mining, chemical, metallurgy and building materials with Mohs hardness of less than 8 and humidity below 6%. High-precision milling of more than 320 kinds of materials in industries (barite, calcite, limestone, potash feldspar, dolomite, glass, gypsum, insulation materials, etc.), and the finished product particle size can be arbitrarily adjusted within the range of 80-480 mesh. Fine up to 600 mesh. Viewed from the outside, it looks like a steel container standing upright, with inlets and outlets, and a feed inlet in the middle. The appearance is similar to the MPS grinding. The Raymond Grinding Roller swivel centerline is upright, and the MPS Grinding Roller swivel centerline is approximately horizontal. The lower part of the mill has a motor to drive the internal grinding roller and the disc to rotate. The material to be ground will be ground or ground. The finished material will be blown through the air from the air inlet. The upper part of the mill has a separator, which can separate the fine powder and then pass through the mill. The wind of the aircraft is taken out by the air outlet.
    The product adopts the advanced structure of similar foreign products and is updated and improved on the basis of large Raymond Mill. The equipment is more efficient than the ball mill, lower power consumption, smaller floor space, and less investment at one time. The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force, so when the grinding roller and the grinding ring are worn to a certain thickness, the production and fineness of the finished product are not affected. The long replacement cycle of the grinding roller and the grinding ring eliminates the shortcomings of short replacement cycles of the consumable parts of the centrifugal crusher.
    The wind-selecting air flow of this machine is circulated and flowed in the fan-grinding shell- cyclone separator-fan, so it has less dust than the high-speed centrifugal crusher, and the operation workshop is clean and the environment is free of pollution.
