Mechanism sand production line to carry out the advantages of construction waste crusher


Construction waste refers to construction waste, spoil, rejects, residual mud and other wastes generated during construction, laying or removal of various types of buildings, structures, and pipe networks by construction and construction units or individuals. Construction waste can be classified according to the source of production and composition. According to the source of production, it can be divided into engineering waste, decoration waste, demolition waste, engineering mud, etc.; it can be divided into waste soil, concrete blocks, broken stones, brick fragments, waste mortar, mud, asphalt blocks, waste plastics, Scrap metal, waste bamboo, etc. The construction waste crusher refers to the use of machine-made sand production lines and other equipment to crush the rubble of these bricks and blocks to meet the needs of turning waste into treasure.
According to the statistics of the country, the amount of construction waste in China has accounted for 30%-40% of the total amount of urban waste. Based on the standard of 500-600 tons/million square meters, by 2020, China will have a new construction area of ​​about 30 billion square meters. The newly-generated construction waste will be a shocking figure. Faced with such a large amount of garbage, we need a professional construction waste crusher method, and the mature machine sand production line is often used as a construction waste crusher production equipment. However, the actual situation is that so far, there is still a lot of construction waste without any treatment for any disposal.
Some building rubbish is randomly placed beside the construction site, some are placed on the outskirts of the country or in rural areas, and it is even more unbelievable that some of them are landfilled directly. These improper practices have greatly reduced the quality of our country’s land. We must not only waste land resources indiscriminately, but also spend a lot of money on the disposal of landfilled waste and destroyed land resources. Therefore, a reasonable and correct construction waste crusher is very important, and Shibang, as a member of the crushing equipment manufacturing industry, also has a very clear social responsibility, and it is necessary to spend more energy to produce suitable construction waste crusher equipment. For example, Simpang has already rationally reformed its existing machine-made sand production line to produce a highly efficient and portable construction waste crusher equipment.
In this way, the problem of excessive construction cost of the construction waste crusher can be avoided, and the consequences of disposing of construction waste can be eliminated, and the destruction of the land due to the improper construction crusher and the destruction of the environment can be avoided. Through practice, it has been proved that random placement, landfill, and burning of construction waste anywhere will cause the garbage to decompose some gases that are not good for the human body in a specific environment. For example, construction waste gypsum contains a large amount of sulfate ions and sulfate ions. Under anaerobic conditions, it will convert to hydrogen sulfide with rotten egg flavor. Waste paperboard and waste wood will liquefy under anaerobic conditions and release chemical gases such as lignin and tannic acid and decompose to generate volatile organic acids. Looking at the moment, the solution to environmental problems is already a huge problem. The state has been working hard for these years, advocating low-carbon, energy-saving, environmental protection, green travel, and the use of natural gas. These are measures to protect the environment. Construction waste is so harmful to the environment. We should naturally take some measures to deal with construction waste in a timely manner so that our environmental protection can be truly implemented.

Raymond Mill’s working technology principle process comprehensive analysis


The natural ore can not be directly put into the raymond mill to directly grind the inside, but it needs the supporting equipment to carry out the simple processing of the ore. Raymond Mill’s complete working system includes jaw crusher, blower, analysis machine (powder selector), pipeline installation, finished cyclone separator, bucket elevator, electromagnetic vibrating feeder, electronically controlled motor, etc. After the material is crushed by the jaw crusher to the required grain size, the material is sent to the storage hopper by the elevator, and then evenly quantified and continuously fed into the main grinding chamber for grinding by the vibrating feeder. The dust after the grinding is blown by the fan take away. After being classified by the analysis machine, the powder with the fineness enters the large cyclone collector along with the gas flow through the pipeline, and is separated and collected. The powder is then discharged through the powder tube as the finished powder. The air flow is sucked into the blower by the return air pipe at the upper end of the cyclone collector. The entire air flow system of the machine is closed and circulates under positive and negative pressure.
Raymond Mill mainframe consists of a frame, grinding roller, grinding ring, blade, air inlet volute, cover and motor. Through its structure, we first look at how its main machine works: Raymonds mill main work process is through the transmission device to drive the central axis rotation, the upper end of the shaft is connected to the plum shelf, the rack is equipped with a roller device and forms a swing fulcrum, grinding roller While orbiting around the grinding ring, the roller itself rotates due to friction. The lower end of the plum shelf is equipped with a blade system, and the position is at the lower end of the grinding roller. During the process of the same rotation of the blade and the grinding roller, the material shovel is thrown into the gap between the grinding roller and the grinding ring to form a mat layer, and the material layer is affected by the grinding roller. Rotation produces outward centrifugal force (ie, extrusion force) to crush the material, thereby achieving the purpose of milling.
In the grinding chamber, due to the moisture content of the material being grinded, the heat generated during grinding causes the gas in the mill chamber to evaporate and change the gas flow, and the pipes of the whole machine are not tightly connected so that the outside air is sucked in, so that the circulation air flow is increased, resulting in milling. Machine out of powder or even burst machine, in this regard, the new European version of the ladder mill has been set in the body with explosion-proof measures, you can maximize to avoid accidental damage caused by Raymond mill explosion, at the same time, The situation can also be achieved by adjusting the balance between the fan and the host to achieve airflow balance, and the excess gas into the small cyclone collector, the residual gas into the fine powder collected, and finally by the small cyclone collector upper section The exhaust pipe is discharged into the atmosphere or introduced into the dust collector to purify the exhaust gas. However, the technical requirements of the operator are relatively high, and they need to be discovered and adjusted in time.
The analysis machine (powder selector) rotates 60 blades on the turntable through a speed-regulating motor and is driven by a secondary deceleration to form a graded effect on the powder. The speed of the blade is adjusted according to the size of the finished powder. In order to obtain finer particles, it is necessary to increase the rotational speed of the blades (at the same time, the wind speed of the fan must be taken into consideration) so that the contact between the blades and the powder increases, and the undesired powder is thrown off from the center air flow by the blades. The powder falls into the grinding chamber due to the effect of gravity and is regrinded. The qualified finished powder is sucked into the large cyclone collector by the air flow through the blade. After the powder collector is separated, the air flow and the powder are separated and the powder is collected.

Raymond Mill introduction and its scope of application


Raymond Mill is a kind of grinding equipment introduced from abroad. The raymond mill is widely used in non-inflammable and explosive mining, chemical, metallurgy and building materials with a Mohs hardness of less than 8 and a humidity below 6%. High-precision milling of more than 320 materials in other 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 air inlet and outlet, 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.

How to Extend the Service Life of Wearing Parts of Construction Waste Treatment Production Line Equipment


The equipment of construction waste crusher production line is dealing with hard stones for a long time and wear is inevitable. Therefore, the selection of wear-resistant materials and the protection of wearing parts are very important for the crusher. Before the selection of wear-resistant materials, we have already made relevant introductions. The technical personnel of Shanghai SBM Technical Department brought us the use and protection of the wearing parts of construction waste processing equipment.
Extending the service life of the wearing parts of construction waste treatment production line equipment is to prolong the service life of the crushing equipment. Hammer heads and counterattack plates and other accessories are very important in the crushing equipment and are the most easily worn parts. In order to extend the service life of the equipment wearing parts, Should be comprehensive management from multiple aspects, and a multi-pronged approach.
1, pay attention to daily operation skills
Commonly used consumables in crushing equipment include hammers, rotors and counterattack plates. For example, the consumables in construction waste disposal line equipment are mainly rotors and plate hammers. The wear parts of the sand making machine are mainly the plate hammers on the impeller. The wear parts of alloy cutter heads, liners, rotors and jaw crushers are mainly screed plates and edge guard plates. The hammers of the hammer crusher are the hammer heads, and the cone crusher consumables are barb walls. And crushing walls. The correct operation skills can effectively reduce the grinding loss efficiency of the equipment and prolong the service life of wear parts. Such as jaw crusher should always check the nuts, bolts, to prevent increased wear and tear, seesaw loose, broken, etc., thereby extending the life of the rocker, reducing costs and improve work efficiency.
2. Choose the most suitable part for different crushing equipment
The types of crushing equipment are various and the models are different. The crusher manufacturers and users should select the most suitable parts for the equipment to prolong the service life of the equipment wearing parts. For example, the choice of hammerhead is: high-chromium compound for small hammerhead, high-manganese steel for sledgehammer, and corrosive material not suitable for forging hammerhead. Different materials have different physical and chemical properties, and the wear of wear parts is also very different. For example, if the quartz rock crushing is easy to happen with the construction of the construction waste processing equipment, the cone crusher should be selected, and the wear-resistant workpiece rolling wall will not be excessively worn.
3, the purchase of construction waste processing line equipment parts selection strength of the big brand manufacturers
Many equipments or wear parts that look the same are used under the same conditions, but their life spans can sometimes differ greatly. Why is this? In fact, we often say that the quality is not good. Every manufacturer has different production scales, different technical strengths, and imperfect hardware equipment. The quality of manufactured parts is also different, and their service life is naturally different. Therefore, Shanghai SBM recommends that when choosing wear-resistant parts manufacturers, we must inspect the factory, including understanding of the plant size, equipment technology, technical personnel, etc., as well as understand the user feedback to select the wear parts.
