characteristics of sand making machine

Introduction to Sand Making Machine Sand Core Crushing Machine In India, also called sand making machine, is a kind of high-energy and low-consumption equipment with international maturity developed by our company's experts based on years of research and development of mining machinery and equipment. Various ore fine crushing equipment plays an irreplaceable role. This machine is also called sand blasting machine, which is the main equipment for producing artificial sand. Sand making machine use Sand making machines are widely used in various ore, cement, refractory materials, bauxite clinker, corundum, glass raw materials, machine building sand, stone, and various metallurgical slags, especially for silicon carbide, silicon carbide, sintered bauxite, and fine sand The high-hard, extra-hard and abrasion-resistant materials are more efficient than other types of machines. Sand making machine works The material falls vertically from the upper part of the impeller into the high-speed rotating impeller. Under the action of high-speed centrifugal force, it will collide with another part of the material that is distributed around the impeller in the form of an umbrella, resulting in high-speed impact and crushing. The eddy currents between the shells are pulverized by multiple collisions and friction with each other. They are discharged directly from the lower part to form a closed circuit multiple cycles. The required particle size of the finished product is controlled by the screening equipment.

jaw crusher development

In the machinery industry, it is a forward-looking method to develop economically and efficiently. Henan Shibang Machinery fully realizes this. When producing a new batch of jaw crusher equipment, it adopts international mature technology, good materials, and strives for Reduce pollution to a lower level. 


In today's society, prices are rising again, and the degree of resource consumption is also rising. Every year, China ’s per capita consumption of electricity, water, coal, oil and other resources has increased by about 17% on average, which is also an important factor causing people to start saving resources. At present, energy conservation and environmental protection are already the obligation of every citizen. The production of new jaw crushers, impact crushers, double-roll crushers, double-toothed roller crushers, slime dryers, drum dryers During the production process, the entire process from the input of raw materials to the output of finished products has no pollution to the environment, and the efficiency of life has doubled compared to previous equipment, and the quality of the equipment is more durable. 

The Cement Plant Crusher For Limestone has a variety of structural forms, and the working principle is the same, that is, the material is broken by the periodic movement of the jaw. During the process of the jaw swinging around the suspension center, the jaw crusher is located between the two jaws. The materials are subject to the combined effects of crushing, splitting and bending. At the beginning, the pressure is small, the volume of the materials is reduced, and the materials are close to each other and squeezed tightly; when the pressure rises beyond the strength that the materials can withstand, that is, Broken

Simulation analysis of dynamics of jaw crusher

The Small Scale Stone Crushers Machines In Kenya can be called an 'antique' class crusher, and its research history is very long. With the rapid upgrading of products, the advantages of jaw crushers are also increasing. Today, they have a large crushing ratio, reliable work, simple structure, convenient maintenance, and economic operation.

When moving the jaw crusher, the key parameters of the jaw crusher, its motion parameters and motion trajectory affect the performance and efficiency of the entire jaw crusher. In order to analyze the dynamics of the crusher, the researchers at the Shibang machine used RecurDyn software to solve the dynamics of the jaw crusher using the theory of relative coordinate system motion equations and a fully recursive algorithm.

The analysis of the mathematical model of the jaw crusher shows that the stroke of each point on the movable jaw and its characteristic value determine the performance of the crusher. The horizontal stroke can produce the compression amount necessary for crushing the material. As the material is crushed, the larger the block size, the greater the compression amount required. Therefore, the general horizontal stroke gradually decreases from the inlet to the outlet. The vertical stroke of the moving jaw causes relative movement in the vertical direction between the moving and fixed jaws to grind the material. At the same time, the friction effect causes wear and tear on the liner of the Hubei and reduces the service life of the liner. It can be known from the above analysis that the stroke characteristic value cannot be too large or too small.

In addition, if the horizontal stroke of the crushing cavity decreases from top to bottom, it will hinder the discharge of the material, and the characteristic value of the crushing cavity decreases from top to bottom, which is not conducive to the crushing process.

The simulation analysis of the jaw crusher dynamics can provide a certain theoretical basis for the optimization of the structure parameters and process parameters of the jaw crusher.

SBM crusher makes sustainable development the first important tas...

Today, I learned from the website of Sino-Singapore that, in order to protect the tranquility and beauty of the mountain village in Switzerland, the residents of a small town insisted on giving up the underground mining of a 1.2 billion US dollars gold mine, and more importantly, this gold mine Once exploited, it will drive great development of the local economy. However, these benefits and benefits still cannot stop the villagers from pursuing the original ecology. This approach has set an important example for the green and environmental protection development of China's mining industry. China is the country with the world ’s largest mineral resources, but backward mining and beneficiation methods have a great impact on our environment. Therefore, in order to protect the environment and comply with the trend of sustainable development, Chinese enterprises must Learn foreign mature technology and the degree of attention to the environment, and do not damage the long-term environmental benefits due to temporary economic benefits. The compulsory state policy and the modernization trend of sustainable development have prompted mining companies to change the traditional extensive mining methods and gradually work hard on new equipment and technological production methods. It is learned from Henan Shibang Machinery that at present, large-scale and technological mining equipment such as hammer crushers, impact crushers, jaw crushers, etc. have tended to large-scale development, and have become a more suitable choice for mine owners. The reason is that this new type of equipment has a high degree of production efficiency and automation, especially a very high degree of environmental harmony. Manufacturers And Suppliers Of Sand Stone Crusher In Delhi takes the realization of sustainable development as the first important task, so it is suitable for the green construction requirements of mining .

SBM series research on jaw crusher

Shibang experts conducted a structural analysis of the simple swing jaw crusher and the compound swing jaw crusher by studying the working principle of the Gypsum Mining Process Machine Price . It can be seen that the application range of the double swing jaw crusher on the market is getting wider and wider. Theoretically, the kinematics analysis of the working device of the crusher was carried out, and the angular velocity and angular acceleration of the moving jaw and the magnitude of the speed and acceleration were obtained through simulation analysis. The position of the eccentric shaft at the maximum value of each speed was obtained. Impact on the crusher. Shibang experts obtained the trajectory of the moving jaw tooth surface through simulation analysis. It is elliptical at the feed port, and the shape is flatter the closer to the discharge port, the shape change has an impact on the crushing and discharge of the material. The characteristic values ​​of the horizontal and vertical strokes of the moving jaw at the feed and discharge openings were calculated. The model meets the production requirements and lays the foundation for the optimization of the crusher mechanism and the simulation analysis of the crushing force. At present, the parametric analysis of the jaw crusher mechanism is mainly a parametric design of the main mechanism size that affects the performance of the crusher, and the design parameters are defined as parameterized variables for parametric analysis. We set up a parametric model of the crusher working device in the visual interface of the ADAMS software, impose constraints on the parametric model, and set simulation steps for simulation analysis and calculation to obtain a better value for the size of the jaw crusher mechanism.

sand making machine Manufacturing Technology in China

At this stage in China, many Sand Making Machine manufacturing are inseparable from the application of automation technology. At this stage, China's sand making machine manufacturing technology has achieved very good development, but compared with the mature countries of the sand making machine industry in the world, there is still a long way to go, China still has a long way to go. At present, China's sand making machine manufacturing technology is still in the primary stage of a sand making machine manufacturing in the world. The level of automation of sand making machine manufacturing is not very high, and the application scope of sand making machine manufacturing automation is not very extensive. In the western countries where the sand making machine manufacturing industry is very developed, there are three applications for sand making machine manufacturing. It is the integration of sand making machine manufacturing; the second is the intelligence of sand making machine manufacturing; the third is the virtualization of sand making machine manufacturing. Western sand making machine manufacturing developed countries have very common applications and promotion on these three issues. China's sand making machine manufacturing lags behind mature western countries in three aspects. One aspect is the innovative design of China's sand making machine manufacturing; the second aspect is the manufacturing technology of China's sand making machine manufacturing; the third aspect is the related management work in the manufacturing process of China's sand making machine. In view of the above-mentioned three gaps, China should attach importance to technological innovation, manufacturing method innovation and management model innovation in the sand making machine manufacturing process at this stage. Only in this way can we keep up with the development pace of mature western countries and upgrade our sand making machine. The level of manufacturing competition has given China's sand making machine manufacturing a certain foothold in the world.

impact crusher

As a crushing machine developed in the 1980s, it has been widely used in sand quarries, and is considered to be an effective sand making equipment by users. It is usually called a sand making machine. The impact crusher uses the diameter of the impeller as the standard to divide the specifications, and is divided into open type and closed type according to the impeller form. According to whether the shell is equipped with a counterattack, it can be divided into two types of crushing methods, namely stone-on-stone and stone-on-iron, so that it is combined into 4 basic forms. From an international perspective, the mature technology of Impact Crusher is reflected in three aspects: flexible mechanical properties, good wear-resistant materials and parts design, and effective dust control. For the domestic market, at least the first two are common. (A) technical performance The open impeller will allow 100-150mm feed granularity, and there is no commercial open impeller impact crusher available to the market in China. Therefore, the domestic vertical shaft impact crusher can only be used as a three-stage or four-stage crushing equipment in a sand and gravel yard, but not as a two-stage crushing equipment as abroad. Foreign companies have equipment with impeller diameters up to 1.6m and supporting motor power Shibang1103kW, which are suitable for various large production lines, while domestic impact crusher specifications rarely exceed 1.2m. Mature impeller channels can be changed between 3-7, with different structures and different speeds to adapt to different materials and feed grain levels, to achieve higher sand production capacity and the need for fineness modulus, and The domestic closed rotor is basically fixed to 4 channels and rarely changes, so the adaptability to different working conditions is poor.

cement rotary kiln

Many parts of the cement rotary kiln require the use of refractory materials, such as smoke chambers, kiln head covers, grate coolers, tertiary air ducts, etc. The smoke chambers generally use high alumina refractory castables, crust-resistant castables, Calcium silicate board, kiln head cover uses high-aluminum high-strength castable, calcium silicate board, grate cooler uses vault alkali-resistant brick, high-alumina refractory castable, steel fiber reinforced castable and other refractory materials Then, what kind of performance do these refractory materials need to meet the production requirements? Let's take a look together.

1.High temperature resistance

In general, the fire resistance of alkaline bricks used in fired belts is as high as 1750 to 1790 degrees, so in general, the fire resistance of fired materials used in fired belts should be 1730 degrees.
2, easy to hang the kiln skin
For the new dry-process Quartz Grinding Machine  , if there is no kiln skin to protect its alkaline bricks, it will cause cracking and spalling because the temperature difference stress in the brick is too large, because the flame temperature in the new dry-process rotary kiln is higher than 1700 ° C. The kiln skin protects the alkaline transition. When the temperature of the kiln changes frequently, the kiln skin is not easy to hang, which will make the alkaline bricks often exposed, which will greatly reduce the life of the alkaline transition.
3. Chemical resistance
Refractory materials must have good chemical resistance. The clinker and kiln skin are still sintered into the refractory bricks after melting at high temperature, because the clinker or kiln skin is chemically characterized by strong alkalinity. We all know that strong chemical attack will change the chemical composition of refractory materials. Especially when the material in the firing zone contains about 20-25% liquid phase. At the same time, the gases produced by combustion and sulfur, chlorine, and alkali volatilized from clinker will also attack various refractory materials.

4. Thermal shock stability
The refractory used must have good thermal shock stability, because under normal circumstances, the refractory in the kiln will be exposed to the hot kiln gas once every turn of the rotary kiln, and the rest will be covered by the material. This will cause the surface temperature of the refractory material in the kiln to be periodically fluctuated, which requires the refractory material to have high thermal shock stability.
In addition to the above points, refractory materials are required to have higher mechanical strength, lower thermal expansion coefficient, and lower porosity.
