    • crushermachine169 has written a new blog article "Factors affecting the feeding effect of Raymond mill" 02.05.2018

      In the Raymond mill milling material production, feeding and feeding effect is one of the important prerequisites for the normal operation of raymond mill. So, in milling operations, Raymond mill feeding effect of what factors?
      1, feeding roller gear type equipped. Under normal circumstances, the common production of milling roller feed the basic tooth-shaped trapezoidal teeth, saw teeth, helical teeth and bovine teeth and so on. In these different types of toothed gear, the trapezoidal teeth are generally suitable for better, less-spun materials, and the saw-tooth is suitable for less-splintered materials. Among them, the trapezoidal tooth not only has strong abrasion resistance, it is not easy to make the material stick to the equipment, become a wider range of use of tooth.
      2, feed roller speed. In Raymond grinding material milling process, the feeding roller speed is an important parameter affecting the feeding effect. If the feed roller speed is too high, the material under the action of a strong centrifugal force may appear in the roller surface slip, or premature throw away from the feeding roller phenomenon. If the feed roller speed is too low, it will not only affect the production efficiency of Raymond mill, but also the average feed effect of Raymond mill.
      3, the gate gap uniformity. For Raymond mill, the uniformity of the gate gap is one of the important factors that affect the feed effect. With the continuous development of Raymond mill technology, the support at the end of the Raymond abrasive gate that is now on the market is adjustable. In order to ensure the feeding uniformity of the small feeding flow, special attention should be paid to the straightness of the knife gate in both directions when machining parts.
      In order to ensure high efficiency and high quality operation of Raymond mill in grinding and milling operations, the fineness of powder can better meet the needs of users and reduce the incidence of failure in grinding operation. Usually, Traffic automatically adjust the function. That is based on changes in incoming material flow to automatically adjust the feed flow to ensure the automatic type of equipment, intelligent and efficient operation.

    • crushermachine169 has written a new blog article "What are the characteristics of China's construction waste?" 02.02.2018

      With the transformation of urban villages throughout the country and the advancement of urbanization, the term construction rubbish has become a hot word in recent years, and construction waste crusher also frequently becomes the hot search word. Construction waste must be familiar to everyone, that is, the construction waste generated after demolition of artificial building structures is generally generated during the construction or repair or demolition of old buildings.
      The main components of construction waste include demolition garbage and construction waste, of which the main components of the garbage include asphalt, brick, concrete, glass, reinforced concrete, soil, plastic pipe, demonstration, sand, gravel, other organic matter, , Bamboo, cable, block concrete, metal and so on. Many of the components in construction waste can be re-used, so we categorize construction waste directly and without hesitation. In fact, it is a waste of resources.
      The amount of construction waste in our country accounts for 30% ~ 40% of the total amount of garbage annually in the city. According to the rough statistics on the construction material loss of brick-concrete structures, fully cast-in-place structures and frame structures, In the process, only 500 to 600 tons of construction waste will be generated; 7,000 to 12,000 tons of construction waste will be generated per square meter of demolished old buildings while 40% of the total amount of demolished buildings will be demolished each year in China. The Ministry of Construction has said that by 2020, China will also add 30 billion square meters of construction area, which can be estimated that the total amount of construction waste will be generated close to 1.8 billion tons. The characteristics of China's construction waste in general have the following characteristics.
      1, a large number
      Needless to say, the quantity is large Needless to say, every time a building is demolished, it will produce hundreds of tons or even thousands of tons of construction waste. In recent years, China has demolished countless old buildings and continuously built new projects. The amount of construction waste generated by this project goes without saying.
      2, universal
      Various cities in the country are engaged in construction, the prevalence of construction waste problems.
      3, regular
      Every day, new construction or demolition projects are taking place in our country, generating new construction wastes every day without interruption.
      4, polluting
      The simple storage and landfilling of construction wastes cause serious pollution to cultivated land, vegetation, water sources and environment, and cause secondary pollution to soil, groundwater and rivers.
      The strategy of sustainable development and environmental protection requirements tell us that the traditional treatment methods for construction waste have become unsuitable for the needs of the current social development. In the current and future development, efforts should be made to improve the utilization rate of construction waste resources. SBM mobile crushing plant to promote the implementation of sustainable development strategy, the construction waste crushing and re-use, making it a reclaimed gravel building materials, recycled brick, green wall materials, improve building waste utilization.

    • crushermachine169 has written a new blog article "Reasons and solutions to the blockage of high pressure Raymond mill in ore" 02.01.2018

      High pressure raymond mill relative to ordinary mill, with higher efficiency and finer fineness of the mill. In the high pressure Raymond grinding ore processing, there will be a variety of failures, thereby affecting the smooth operation of milling operations, plugging is one of the common. Once the mine high pressure Raymond mill blockage, it will seriously affect the correct operation of equipment, not only delayed milling process, but also directly affect the user's economic returns. So, ore high pressure Raymond mill jamming causes and solutions what?
      1, the feed size is too large. If the size of the ore material is too large, it is easy to cause the material in the feeding process to appear stuck in the feed inlet occurs, which will directly cause high pressure Raymond mill ore blockage. To this end, we have to strictly control the feed size, so as to avoid excessive particle size caused by ore high pressure Raymond mill blockage.
      2, causing too fast feed blockage. When the staff of the ore high pressure Raymond mill feed too fast, it will cause the grinding chamber material accumulation, thereby reducing the production capacity of the equipment, and ultimately Zhao Cheng ore high pressure Raymond mill blockage. Therefore, if it is caused by the cause of feed blockage, the user should first clear the feed inlet material, and change the feeding method, by increasing the feeding amount of feed control methods to achieve the purpose of adjusting the feed rate, thereby preventing high pressure ore Raymond mill blocked.
      3, equipment load operation. Any equipment has a certain load limit, once the ore high-pressure Raymond mill oversupply state for a long time, it will lead to equipment overload due to prone to blockage. At the same time, overload will cause the motor overload operation, resulting in severe motor burnout phenomenon, affecting the normal operation of milling equipment. Therefore, when we use high pressure Raymond grinding ore, we must choose the right Raymond mill model according to the actual situation, and the equipment is working, the current is controlled at 85% of the rated current to improve the blocking phenomenon.
      In addition to the above points, if the high-pressure ore Raymond wear parts appear aging, but also easy to make the formation of clogging powder production. Therefore, we are in the daily use of high pressure Raymond mill ore, pay attention to the maintenance of equipment, regular inspection of the performance of the various components, so as to avoid clogging due to aging parts.

      According to statistics, at present, the total amount of construction waste in our country is 2.1 billion tons to 2.8 billion tons and more than 300 million tons of construction rubbish are newly generated every year. However, China's construction waste treatment is very simple, the traditional method is mainly temporary storage and landfill disposal. This will not only encroach on the land, but also undermine the ecological balance of the environment.
      Domestic waste is being classified and reused, and is called misplaced resources, then construction waste can also be turned into treasure? However, this is no longer an illusion, SBM mines developed this machine & mdash; construction waste mobile crushing plant. Construction waste crusher is divided into crushing, screening two frames, as long as a bulldozer, will sort the good construction waste pushed to the feeder, chunks of stones are sent to the crusher. After classification, the construction rubbish is sent to the vibrating screen through the belt conveyor, the iron remover is fixed above the belt conveyor, the iron wire and the screws in the rubbish are all cleaned out. After entering the vibrating screen, the fine sand is sent out through one of the leather belt conveyors below. The larger one does not meet the specifications, and is sent to the crusher by another belt conveyor. This is repeated.
      According to SBM mine machine sales to Zhengzhou customers, this machine can handle construction waste 1 million tons, has produced standard building materials products are recycled aggregate concrete, recycled aggregate permeable concrete, recycled coarse, fine aggregate and gas Concrete blocks, resource utilization rate of 98% or more.
