What causes the unstable operation of the mobile crushing station?

January 12, 2020 by xiaoxuanxuan  

For the Portable Crusher Plant, if the operation is unstable in production, it needs to be stopped and repaired. In order to reduce the impact of the shutdown and maintenance on the production process, here is the introduction of the factors that cause the unstable operation. Similar problems can be found by users based on these reasons, saving time for maintenance. Generally speaking, there are four main reasons for the unstable operation of the mobile crushing station, which will be described in detail below. Cause one: uneven oil supply If the mobile crushing station reaches a high speed without load and continues to increase the speed, the centrifugal force of the regulator flying block will be too large, the tension of the speed control spring will be overcome, and the oil supply gear rod will be reduced by pushing the tension rod. Move in the direction. At this time, the position of the fuel supply rod is equivalent to the position of the fuel supply gear rod at low speed. Therefore, if the fuel supply is uneven, the error will be too large, which will affect the stability of the operation. Cause two If the mobile crushing station reaches the oil stop speed, the fuel injection pump should automatically cut off the oil, but if the quality of the plunger and the valve components is not uniform, or due to the different wear and tear caused by the oil break time, some cylinders may have been supplied with oil, Some cylinders have a small amount of oil supply or slow oil cut-off, which will cause the unstable high-speed operation; Cause three: improper operation If the mobile crushing station is running at a high speed, some incorrect operations occur, such as the feeding equipment suddenly increases the feeding, or the nature of the supplied material changes. If the machine is not adjusted, it will cause The station appears to be flickering, and at this time, it needs to stop immediately for inspection; Cause four: Improper speed adjustment The unstable high-speed operation of a mobile crushing station usually manifests as high-speed instability under load. Speed ‚Äč‚Äčregulation is an important indicator for evaluating the performance of a governor. If the speed is too large, the speed of the diesel engine will fluctuate greatly when the load changes. Affects the stability of the engine's high-speed operation, and the idle speed is too high, which will increase the wear of the body, and the regulating speed is too small, which will also cause the high-speed operation to be unstable. It is better to control the regulating speed of the vehicle to less than 10%

Construction waste treatment scheme

January 6, 2020 by xiaoxuanxuan  

All kinds of wastes are produced in all walks of life, especially the construction industry produces a lot of various kinds of construction wastes every year. According to statistics from relevant departments, China's existing building area totals more than 40 billion square meters. Based on the standard of 500t to 600t of construction waste generated per 10,000 square meters of building construction, China's existing building area has generated at least 2 billion tons of construction waste. By 2020, China will also add about 30 billion square meters of construction area, and the newly generated construction waste will be an astronomical figure. In most places, construction waste is disposed of in landfills or stacked in the open air. If landfilling or open storage is not a long-term solution, it will not only pollute the environment, but also a waste of resources. Here are some examples of construction waste disposal methods: Reuse of old wood and sawdust: Old wood removed from buildings can be reused directly as wood. Broken wood, sawdust and sawdust from construction waste can be used as a cover in fuel composting and erosion projects. Compared with ordinary concrete, waste wood is used to produce clay, wood, cement composite materials, which has the advantages of light weight and low heat conductivity. Can be used as a special insulation material. Reuse of old bricks and tiles: Bricks and tiles in construction waste can be cleaned and reused. Waste bricks, tiles and concrete are crushed and screened by Construction Waste crusher equipment. After cleaning, they can be used as recycled aggregates to prepare low-standard recycled aggregate concrete. Manufactured in road engineering cushions, indoor floors and floor cushions, non-load-bearing concrete hollow blocks, concrete hollow partition boards, autoclaved fly ash bricks, etc. The recycled aggregate component contains a considerable amount of cement mortar, which results in high recycled porosity and large water absorption. Recycling of scrap metal and steel: Construction waste treatment equipment is equipped with iron removers to sort scrap metal and steel. The sorted scrap metal and steel can be sent to iron and steel plants or non-ferrous metal smelters for refining; Recycling of waste linoleum: After being crushed, sieved, and cleaned by construction waste treatment equipment, it is used as concrete aggregate or sintered brick. Reuse of old asphalt pavement: The old asphalt pavement is crushed and screened by Construction Waste crusher equipment, mixed with recycled materials, new aggregates, and new asphalt materials in appropriate proportions to form a certain pavement of recycled asphalt concrete for paving the road The surface layer or base layer, the asphalt roofing material contains high-quality fillers, which can replace part of the cold-mixed and hot-mixed asphalt. The asphalt layer material also has a fibrous structure, which helps improve the performance of the hot-mixed asphalt. Concrete accounts for about 30% of the total construction waste, which is an important component and the part with the highest recycling value. After being broken by construction waste treatment equipment, concrete can be used for recycled concrete and recycled cement. As a roadbed material.

Equally important to ensure the quality of Raymond mill components

December 30, 2019 by xiaoxuanxuan  

Raymond mill is a relatively high frequency machine used in grinding machines.We can see whether Raymond mill is large or quite advanced in many places, such as ultra-fine raymond mill, high-pressure Raymond mill, important components of mining machinery. Mechanical wear is inevitable and replacement of mechanical parts cannot be avoided. How to ensure the quality of parts is a problem that enterprises pay great attention to. It is equally important for Raymond mill accessories manufacturers to ensure the quality of each component and the overall quality of Raymond mills. If you can't make the details perfect, how can you ask the whole machine to be good? Ensuring good quality can effectively prevent substandard products from entering the market. Ensuring high quality shows the indispensable responsibilities of the business. If we allow unqualified products to circulate on the market, it is disrespectful of people's lives. Quality inspection can timely find some wrong processing, assemblers, welders and factory workers, can also prevent some defective products or waste products from being mixed into the finished part.The processing process is a manual operation process, so it is impossible to completely avoid defective products or waste products. Happened, but when there are defective products or waste products, we must check in time to ensure that customers get qualified products.

SBM Heavy Industry High Pressure Mill, Desulfurization Gypsum Mill Processing

December 27, 2019 by xiaoxuanxuan  

Thermal power generation is the new force that produces desulfurized gypsum. This is mainly because the method of generating points with thermal power stations is to burn a large amount of coal and exchange heat for electrical energy for generating points. It is the most efficient method among all methods but it is currently the most used method in China . This directly produces a large amount of desulfurized gypsum. How to deal with these desulfurized gypsum has become a top priority for all practitioners. In the past, we used the landfill method to directly bury the desulfurized gypsum, but later we found that this method would cause serious soil pollution. Today, the application of desulfurized gypsum is mainly used in building powder, building materials, building gypsum, etc. The application of these desulfurized gypsum often requires milling. Due to the huge stock of desulfurized gypsum, the quality and efficiency of small scale mining equipment gold has become the basis and key to market competition. The mill is the decisive factor for the quality and efficiency of powder products. If you are thinking about engaging in the desulfurization gypsum treatment industry, SBM Heavy Industry High Pressure Mill is your ideal choice. This industrial mill was successfully researched by the technical staff of SBM Heavy Industry after fully studying the advantages and disadvantages of traditional Raymond mills, combining the manufacturing technology of some foreign advanced mill manufacturers, and successfully developing this New high pressure mill. On the basis of ensuring the fineness and quality of the powder, this large-scale mill can increase the output to more than twice that of the far Raymond mill. China's comprehensive treatment and application of desulfurized gypsum is still in its infancy. Whether it is method, consciousness or government policy, it has yet to be transformed, strengthened and deepened. However, it is certain that desulfurized gypsum will become more and more active in the market as a building material, and this market will become larger and larger.

What causes Raymond mill odor?

December 24, 2019 by xiaoxuanxuan  

During the use of the raymond mill, if a strange odor occurs, a shutdown inspection is required. This phenomenon indicates that a certain part of the equipment has a condition. If it continues to run, serious things will happen and eventually the equipment will appear. Malfunction and scrapping, then, what causes the odor? 1. The smell of rubber paste. This odor is easy to distinguish. When this odor occurs, it is necessary to check the belt and Raymond mill in time to see if the parts belonging to the rubber product are loose, slippery or overheated. What needs to be reminded here is that if the problem occurs in the engine, it needs to be stopped immediately, and it can be run only after the heat is released. 2. The smell of plastic paste, which generally occurs in the summer, due to the weather, the wires inside the equipment are overheated. Its plastic outer sheath is thin, so the smell is not great, but it is highly dangerous, easily causing circuit damage, engine stall, and spontaneous combustion of the entire vehicle. When the wire is overheated, there will be local smoke and heat. Stop immediately to find out why. 3. Unburned gasoline smell. When the operator can always smell the unburned gasoline smell, it is necessary to check whether the phenomenon of oil leakage has occurred. During the long-term use of raymond mill, the oil pipeline is bound to age badly. Fuel leaked out of it. When you smell a smell of gasoline, you should stop immediately, do not ignite the fire. After inspection, if you find an oil leak, then here at SBM Heavy Industry teach you a trick, you can use chewing gum to directly stop the leak The position of the oil is fixed with tape. This method is only a measure of delaying, so it is effective to find professional personnel for repair as soon as possible.

Composition and description of sand making machine structure

December 23, 2019 by xiaoxuanxuan  

No matter what equipment is constructed from multiple parts, the sand making machine is now one of the main products of Shanghai SBM Heavy Industry. Many customers who buy sand making machines only know that the sand making machine is used to make stones into sand. It is also unclear what the sand making machine is composed of, here SBM Xiaobian makes a detailed description of the structure of the sand making machine. The sand making machine produced by Shanghai SBM is composed of seven parts, such as a feed hopper, a distributor, a vortex crushing cavity, an impeller body, a main shaft assembly, a base, a transmission device and a motor. Feed hopper The structure of the feed hopper is an inverted prism (or cylinder). The feed port is provided with a wear ring. The incoming material from the feeding equipment enters the crusher through the feed hopper. Distributor The distributor is installed in the upper part of the vortex crushing chamber.The function of the distributor is to divide the material from the feeding hopper, so that a part of the material directly enters the impeller through the central feeding pipe and is gradually accelerated to a higher speed and ejected. , Make another part of the material from the outside of the central feeding tube, bypass into the outside of the impeller in the vortex crushing chamber, and be crushed by the high-speed material ejected from the impeller, without increasing power consumption, increasing production capacity, and improving crushing efficiency . The structure of the vortex crushing cavity is an annular space composed of upper and lower cylinders. The impeller rotates at high speed in the vortex crushing cavity, and the material can also reside in the vortex crushing cavity to form a material lining. The crushing process of the material occurs in the vortex crushing cavity. The crushing effect is separated by the material lining layer, so that the crushing effect is limited to the material, and it plays the role of wear-resistant self-lining. The observation hole is to observe the wear of the wear block at the launch port of the impeller flow channel and the wear of the lining plate on the top of the vortex crushing chamber. The observation hole must be tightly closed when the crusher is working. The distributor is fixed on the upper cylindrical section of the vortex crushing chamber. The impeller rotates at high speed to generate air flow, and the internal self-circulation system is formed in the vortex crushing chamber through the distributor and the impeller. Impeller The impeller structure is a hollow cylinder made of special materials. It is installed on the upper end of the main shaft assembly. It uses a conical sleeve and a key to transfer the button distance and rotate at high speed. The impeller is a key component of the sand maker. The material enters the center of the impeller through the central feeding pipe of the feeder on the impeller. The cloth cone in the center of the impeller distributes the material evenly to each launching runner of the impeller, and a wear-resistant block made of special material is installed at the exit of the launching runner, which can be replaced. The impeller accelerates the material to a speed of 60-75m / s and ejects it out of the base. The vortex crushing cavity, the main shaft assembly, the motor, and the transmission device are all installed on the bottom seat. Used to install the main shaft assembly, forming the discharge channel on both sides. Double motors are installed at the longitudinal ends of the base. The base can be installed on the bracket or directly on the foundation. The transmission device adopts a single-motor or dual-motor driven belt transmission mechanism (more than 75kw, dual-motor transmission). The two motors drive the two motors installed on both sides of the spindle assembly, and the two motor pulleys are connected to the spindle pulley with a belt. The forces on both sides are balanced and no additional moment is generated. Brackets Depending on the work place of the crusher-open-air or indoor work, consider installing a bracket or not. The lubricating system adopts special grade centralized lubrication for vehicle grease. The lubricating parts are the upper bearing and the lower bearing of the main shaft assembly. In order to facilitate oil injection, the oil pipe is used to lead to the outside of the machine.
