Advantages of High Pressure Roller Grinding Machine High pressure roller grinding machine is specially designed and manufactured for the metallurgical mining industry. After years of research and practice, our factory has developed it based on domestic processing and manufacturing technology in combination with my country’s national conditions. High pressure roller grinding machine is specially used for ore crushing. Due to the large crushing ratio of this equipment, it can replace the existing three crushing, fine crushing and coarse grinding operations in the crushing and grinding process, and can grind 30-60mm ore to less than 3mm, so that a large amount of tailings can be discarded before grinding, so that the grinding and beneficiation capacity of the system can be greatly improved. For the lean ore, extremely lean ore, and off-balance ore of iron ore mines, after being processed by the high pressure roller grinding machine, more than 50% of the tailings can be discarded before grinding, and the grade of the ore entering the mill can be greatly improved. The original grinding and beneficiation capacity has been increased by more than 100%, the power consumption of grinding has been greatly reduced, and the beneficiation cost has been greatly reduced. After the tailings are discarded before grinding by high pressure roller mill, the discarded tailings can be classified. The coarser tailings can be used as building stones or replace river sand, or directly sent to the waste rock dump, thereby reducing the content of fine tailings and extending the life of the tailings pond. In addition, due to the small wear, the unit wear is greatly reduced. At the same time, the noise and dust are small, which improves the working environment of workers and fully demonstrates its economic and social benefits.
There are several common problems in the use of marble sand making machine Marble is an important building material and industrial material. Natural marble cannot be used directly and needs to be trimmed with mining machinery equipment. The more commonly used “shaping” tool is the marble sand making machine. 1. The amplitude of the marble sand making machine is too large The marble sand making machine should be relatively stable during operation. Although the impact of marble materials on the equipment is relatively large, the marble sand making machine currently produced can already cope with the strong impact of the material. Due to long-term wear, excessive feeding or high-hardness foreign matter in the feed, the marble sand making machine will cause the equipment amplitude to increase. At this time, it is necessary to replace the wearing parts in time, reduce the feed particle size, strictly control the feed, and ensure that no high-hardness foreign matter appears during the feeding process. 2. The finished sand output particle size is large The main reason why the finished sand particle size processed by the marble sand making machine is too coarse is the looseness of the V-belt. At this time, the V-belt should be tightened in time; the wear of the marble internal screen sand making machine will also cause the marble finished particle size to be too large. At this time, the screen should be replaced in time, and the wear of the filter should be checked before each operation. 3. Bearing overheating The marble sand making machine may have bearing overheating during operation. The main reason is lubrication. Check whether the lubrication is good and whether there are impurities in the bearing. If there are impurities, clean the bearing in time. Long-term wear can also cause bearing overheating. If the bearing is found to be worn, it should be repaired in time. If the wear is serious, it should be replaced in time.
To purchase a fine sand recovery machine, you must first determine the model and then choose the manufacturer There are more and more manufacturers producing fine sand recovery machines on the market, and the quality of the equipment is also different, and the price is even more confusing. How to choose a machine that suits your production needs and what price to order is reasonable has become a problem for investors. Customers cannot blindly consult the price of the equipment first, which is wrong. Because fine sand recovery machines will have many models; the correct approach is: first, determine what material you want to recover fine sand, how big it is, how big the particle size of the finished product is, how much is the expected output per unit time, and how much volume of fine sand recovery machines the production environment can accommodate. Make detailed statistics, and Quanzhou Hot Wheels Machinery professionals will provide models of fine sand recovery machines that suit your production needs. After determining the model, it is time to choose a manufacturer. The choice of the manufacturer is very important, not only related to the quality of the equipment, but also affecting the future maintenance and after-sales service. Hot Wheels Machinery recommends that customers choose several manufacturers with good reputations; for example, Hot Wheels Machinery, etc. It mainly depends on the size of the manufacturer, the sales volume of the equipment manufactured, the user feedback, the strength of the technical team, and the perfection of the after-sales service. Here I recommend the Hot Wheels mechanical machine. Due to different manufacturers and different technologies used, there must be differences between the equipment. It is normal for the prices to be different. Although everyone knows that you get what you pay for, expensive products are not necessarily good products, so you must carefully compare the details of the equipment.
Sand washing machines play a certain role in washing and selecting in many stone production lines. Sand washing machines can easily remove impurities on the surface of sand and gravel aggregates. In addition to those sand making production lines and sand and gravel production lines, sand washing machines are required. There are many other operations for washing minerals, and I will introduce them to you below: First, there is a big difference in the selectability between the original slime and the ore of some ores. By using a sand washing machine to separate the mud and sand and process them separately, better selection indicators can be obtained; Second, the ore needs to be manually selected or photoelectrically selected, and the sludge contaminates the surface of the ore, making it difficult to identify. At this time, a sand washing machine must be used to wash the ore before hand selection or photoelectric selection; Third, hematite and limonite contain a lot of clay. If the cement clay contains very little iron minerals, the mud can be discarded as the final tailings after washing with a sand washing machine, and the grade of the resulting ore will be can be greatly improved; Fourth, the ore contains a lot of mud, which often blocks the fine crusher, screen and ore port, making the production line process or production operations difficult to continue. It can be processed by the sand washing machine ore washing method. The company mainly produces various types of mining machinery products such as vibrating screens, feeders, conveyors, sand washers, crushers, fine sand recovery machines, sand making machines (high-pressure roller mills), dewatering screens, trommel screens, etc. And its supporting accessories are widely used in mining, cement, highway, high-speed rail, metallurgy and other industries.
Sand washing machine construction sand has a wide range of uses. Sand is one of the main components of concrete and mortar. It is a bulk material for civil engineering. Sand is generally divided into two categories: natural sand and artificial sand. It is produced by natural conditions, mainly rock weathering. The formed rock particles with a particle size of less than 5mm are called natural sand. Artificial sand, namely machine-made sand and sand washing machine, refers to rocks with a particle size of less than 4.75mm that have been processed by soil removal, mechanically crushed, and screened. Particles, but does not include particles of soft rocks and weathered rocks. The specifications of sand are divided into three types: coarse, medium and fine according to the fineness modulus (an indicator of the thickness and type of natural sand particle size). Sand washing machine coarse sand: fineness modulus is 3.7-3.1, average particle size is o. 5mm or more. Sand in sand washing machine: fineness modulus is 3.0-2.3, average particle size is o. 5-0.35mm. Sand washing machine fine sand: the fineness template is 2.2-1.6, and the average particle size is 0.35-0.25mm. Extra fine sand for sand washing machine: fineness modulus is 1.5~0.7, average particle size is below 0.25mm. The larger the fineness modulus, the coarser the sand. The fineness modulus of ordinary concrete sand ranges from 3.7 to 1.6. Medium sand is suitable, or coarse sand plus a small amount of fine sand, the ratio is 4:1. The particle gradation of the sand in the sand washing machine refers to the matching ratio of sand size particles. If the sand is of the same thickness, the gaps will be large. If the sand of two particle sizes is matched, the gaps will be reduced. The sand of three particle sizes will be matched. The voids are smaller. It can be seen that the void ratio of sand depends on the matching degree of the particle sizes of the sand materials at all levels. The well-matched sand can not only save cement, but also improve the density and strength of concrete and mortar.
Teach you how to improve the efficiency of fine sand recovery machine! In order to further achieve the purpose of improving efficiency, methods are given to improve the efficiency of fine sand recovery machines, which are mainly reflected in: 1. The value of the fine sand recovery machine itself or its subsequent services. 2. Reduce the cost of the fine sand recovery machine itself or the service. Only in this way can we maximize the stimulation of customers to buy our products. In terms of production, if we want to reduce the cost, we can only start from the labor aspect, not the technology or efficiency. At the same time, this problem also plagues many fine sand recovery machine manufacturers. In addition, another more important issue is that the industrial value chain of the entire sand making production line is relatively high, and at the same time, manufacturers have relatively weak control over its additional environment. Therefore, the profits earned by additional manufacturers are only in the value chain. Lower, but also need to bear higher risks and fixed costs, including environmental and social investments. It can be seen that in order to effectively improve the production efficiency of fine sand recovery machines, our innovation must be based on the interests of producers and follow the development of society to adopt good methods to effectively improve sand production efficiency. At the same time, we also need to establish effective and feasible industry standards to exert certain constraints on producers and eliminate the original irregular production (that is, we produce whatever customers need, and most of the materials used are inferior and non-standard). Environmentally friendly, if things go on like this, vicious competition in the same industry will form a “price war”). The victims behind the formation of this business model are the producers. It is not only detrimental to the publicity of the manufacturer, but also seriously hinders the recycling of fine sand. The research and development and progress of new technologies in machinery and equipment. Generally speaking, in innovative operations to improve the efficiency of fine sand recovery machines, it is still necessary to establish practical industry standards. Only in this way can the development of fine sand recovery machine manufacturers be more secure.

How to distinguish between sand washing machine and sand making machine Many customers can’t tell the difference between “sand washing machine” and “sand making machine”. The editor tells us that in order to understand the difference between “sand washing machine” and “sand making machine”, we need to first understand the difference between “sand from water” and “sand from stone”. The difference between “sand from water” and “sand from stone”: Literally speaking, “sand from water” is generally related to water, usually referring to river sand. “Sand from stone” is related to stone, usually referring to crushed stones with smaller particles. Divided according to particle size: sand from water < sand from stone < stone. The difference between “sand washing machine” and “sand making machine”: Knowing the difference between sand from water” and “sand from stone”, it is easy to understand the difference between “sand washing machine” and “sand making machine”. The sand washing machine is mainly used for river sand clean, that is, to clean the soil and impurities in the river sand. The sand making machine is mainly used for cleaning the powder produced after crushing sand and gravel and for secondary crushing of sand and gravel. It can be seen that the function and machine strength of the sand making machine are greater than that of the sand washing machine, and there is an essential difference between this two kinds machine.
What is the problem with the slow discharge of materials from the vibrating screen? When vibrating screens handle materials on a daily basis, they may encounter slow discharging. The following situations and solutions are summarized for the reference of users: 1. Check whether the screen and the trash discharge port are level or too high. Generally, they should be about 5mm higher. The height of the discharge port is designed differently according to different material characteristics. 2. When the vibrating screen is working, check whether the screen surface or the discharge port is in a horizontal state. This is directly related to the screening effect of the equipment; if it is not horizontal, it must be adjusted in time. The vibrating screen produced by Hot Wheels Machinery All are equipped with supporting feet. Customers can adjust the feet to make the vibrating screen meet the horizontal requirements and lower it appropriately. 3. In addition to the above situation, the key point is to adjust the angle of the upper and lower eccentric blocks of the vibration motor. A smaller angle will cause the material to spread out faster, whereas a larger angle will make the material spread out more slowly. When changing the angle of the vibration motor eccentric block, it should be adjusted by about 5 degrees. If you have strict requirements for screening accuracy, the motor angle should not be too small, otherwise the material will spread out quickly, which is detrimental to the screening effect. Generally When the vibrating screen leaves the factory, the angle of the motor eccentric block is 45°.
