Introduction to machine sand equipment knowledge


With the pull of domestic demand, the investment in infrastructure such as roads and railways is increasing, and a large amount of sandstone is urgently needed. In order to protect the ecological balance, the state expressly prohibits the excavation of natural sand (except for clearing river courses). The supply of natural sand can hardly keep up with demand. Therefore, the development of the mechanism sand is very urgent to mention the agenda. In view of the fact that the mechanical sand is rock blasting, mechanical sand or river pebbles are sanded and sieved by sand making machine, and its strength and other properties are superior to natural sand. Mechanical sand is superior to natural sand in both physical and chemical properties. We must stand at the strategic height, establish and implement the scientific development concept, enhance the sense of responsibility of human environmental protection, vigorously develop and actively promote the mechanism sand equipment. Although China’s research and development of mechanical sand technology and equipment started late, the development is slow. Some large-scale water conservancy projects use artificial sand. Many of the key sand making machines are imported from abroad. There is still a certain gap between the development of domestic mechanical sand equipment and the advanced level of foreign countries. However, we believe that after a period of hard work, it is able to catch up with or surpass foreign similar equipment. Nowadays, it is still good to use some mechanical sand equipment in China. It is worthwhile to choose sand making materials as appropriate. The requirements of sand and gravel industry are different from those of mine grinding industry. At present, most of the companies that produce sand-making equipment are responsible for the mining machinery manufacturing industry. Therefore, we must first understand the requirements of sand and gravel. 1. The granule requirements of the mining equipment for sand making materials are fine. In general, the needle-like material enters the mill and is more susceptible to grinding. The requirements for gravel are contrary to the above, and the requirements for grain size and grain size are very strict. The reason is that the cubic sand has a function of locking each other due to its angular shape. The continuous grading of the sand can greatly reduce the gap. At the same time, the cubic sand occupies a larger surface area than the round sand, which makes the asphalt and materials or cement and materials stick together to reduce the possibility of displacement. 2 According to the definition of the mechanism sand: rock particles with a particle size of less than 4.75 mm made by mechanical Sand making machine and sieving after soil removal treatment. But does not contain soft rock, weathering rock particles. 3 sand specifications: sand specifications are divided into coarse, medium and fine according to the fineness modulus (Mx). Among them: the fineness modulus of coarse sand is 3.7~3.1, the fineness modulus of sand is 3.3~3.0, the fineness modulus of fine sand is 2.2~1.64, and the grade of sand is divided into: I, II, III according to its technical requirements. Three levels. Uses: Class I sand is suitable for concrete with strength grade greater than C6. Class II is applicable to concrete, hydraulic concrete with strength grades C30~C60 and antifreeze, impermeability or other requirements. Class III sand is suitable for concrete and construction mortars with a strength class less than C30. Characteristics: The particle size of sand is between 4.75~0.15mm, and the stone powder less than 0.075mm should have certain limits. The particle size is 4.75, 2.36, 1.18, 0.60, 0.30, 0.15, preferably continuous, and each A certain grade should have a certain percentage, and its granular shape is preferably a cube, and its needle-like content is also required. There are many mining equipments suitable for the production of sand. However, for the moment, there are mainly the following seven types: 1. Vertical impact sand making machine; 2. Counterattack fine sand making machine; 3. Jaw crusher; 4. Roller sand making machine 5. Cone sand making machine; 6. Rod mill. These sand making equipment have different characteristics and each has different uses.

Jaw crusher becomes an important crushing device for coarse crushing


The jaw crusher has always been an important crushing device for the coarse crushing process in the stone production line and the sand production line. Since the feed port of the jaw crusher is large, it is a primary crush in the crushing production line, which shows his importance. The traditional PE series jaw crusher is a toothed plate extrusion type of round-trip crushing, and the broken material can only meet the requirements of entering the impact crusher and fine crusher for crushing production. Therefore, he is usually in the stone production line. The highest point is broken.
As a new generation of high-performance crusher, jaw crusher surpasses traditional E-break in performance, maintenance cost and structure, and can be widely used in metal and non-metal mines, cement, construction, sandstone, metallurgy and other industries. PE series high-energy rupture is used in the production process of building gravel and machine-made sand, especially when crushing hard materials such as basalt, it has higher production efficiency and lower running cost than traditional smashing.
According to the principle of the PE series jaw crusher, a buffer spring is added to the back, so that it can play the role of buffering the pressure during the production, which further increases the particle size and the degree of extrusion, if it is in production. When the discharge is too large, only the adjustment of the bolts behind will strengthen the discharge particle size of the entire stone production line to alleviate the pressure of the secondary crushing to achieve the overall production efficiency improvement, and the discharge granularity is uniform.

Is the processing calcite using an ultra-fine grinding machine?


Calcite A mineral containing high natural calcium carbonate, which is widely distributed throughout the world. The gloss of the glass is presented, the Mohs hardness is 3, and there are many mechanical equipments for processing calcite. Then, is the processing calcite using grinding milling machine? What are the advantages?
Feasibility analysis of calcined powder by ultra-fine grinding machine
The ultra-fine mill using the principle of intergranular lamination is used to grind calcite. In the crushing chamber, the phenomenon of “stone crushing” is presented, which replaces the traditional single-grain grinding principle, which not only realizes the selection of materials. Sexual processing, but also can significantly increase the product fines ratio and cube content, greatly reducing the needle-like material, at the same time, can also reduce the wearing of wearing parts
Secondly, in the modular design of the ultra-fine mill, Shanghai SBM can realize the conversion of coarse, medium and fine crushing by changing the cavity type. The processing granularity can be switched between 300 mesh and 3000 mesh, and the production can be improved. At the same time of benefit, it can also meet the large production demand of the customer’s other stone powder products, so in general, the use of limestone mill to process calcite is a natural fit.
The production process for processing calcite using ultra-fine mill is as follows:
Firstly, the raw material is broken into the jaw crusher by the vibrating feeder, and the crushed calcite stone is evenly conveyed by the belt conveyor to the ultrafine mill for the second crushing and grinding. The produced ore fine material is rounded. The sieve is sieved, and the larger stone is returned to the grinding chamber for processing again. This is called returning; other suitable stone materials are sent to the modification machine for modification. This step depends on the customer’s needs. If the quality of the stone is not high, you can omit this step and send it directly to the packaging collection.
Is the processing calcite using an ultra-fine grinding machine? The answer to this question is already obvious. Shanghai SBM is committed to research and development of equipment for processing and processing calcite for more than ten years. It has superb technology and perfect pre-sale, sale and after-sales service. You are welcome to call us.

Analysis of the cone crusher in the stress


The cone crusher is an important ore dressing equipment with relatively large body shape. During its operation, the wear of the parts will seriously affect the vibration stability of the crusher, and at the same time, the machine will be in a state of forced vibration for a long time, which will seriously affect the crusher. Safe to run. The study found that the disturbance is an important factor affecting the forced vibration of the crusher. Let us analyze it here.
According to the angular velocity vector diagram of the crusher cone crushers, due to the structural characteristics of the crusher cone support device, the crushing cone not only rotates with the eccentric hole of the eccentric bushing around the center line of the machine, but also rotates around its own axis, which is the crushing cone. This kind of movement is called regular movement. Since the center of mass of the crushing cone is not on the center line of its rotation, it is necessary to generate inertial force and moment of inertia during operation. This force acts on the frame as a periodic dynamic load that causes the vibration of the frame and the deflection of the eccentric bushing. When the crusher makes regular movements, it periodically reacts to the frame sleeve and the spherical bearing during no-load, which causes the harmful vibration of the frame machine and the eccentric bushing to be deflected and cannot work normally.
The counterweight of the large bevel gear of the slag crusher is to eliminate the inertial force and the moment of inertia of the direction change caused by the crushing cone. Due to the limitation of the size of the crusher, the inertial force of the crushing cone cannot be completely eliminated. Therefore, when the crushing cone rotates, a large unbalanced inertial force is generated. This unbalanced inertial force is caused by the crusher frame and the basic vibration. Disturbance. That is, the disturbance of the crusher is the unbalanced inertial force generated when the crusher’s crushing cone rotates around the central axis. Vibration analysis under disturbance. The vibration of the machine can be divided into two types: free vibration and forced vibration. The body and foundation of the crusher are constantly excited by the outside world, and there is always disturbance during the whole vibration process, so it is a typical forced vibration.

The sand making machine is a kind of gravel equipment mainly composed of a feeding hopper, a distributor, a vortex breaking chamber, an impeller, a main shaft, a base, a transmission device and a bracket. The impact sand making machine is a new type of sand making machine modified according to the principle of the sand making machine.
In various stone production lines and sand production lines, sand making machines are generally equipped with crushers for re-crushing. Therefore its installation has a lot to do with the crusher. The location of the impact sandblaster will vary depending on the location of the crushing site. It is usually installed in a factory building or in an open space.
Before installing the impact sand making machine, first check the packing list to check whether the various parts are worn or not during transportation. During the installation, the sand making machine should be leveled so that its main axis is perpendicular to the horizontal plane. Appropriate space should be left above and on both sides of the sand making machine for hoisting and maintenance. After the installation is completed, a full inspection should still be carried out, for example: whether the lubricating oil pipe is securely connected.
The impact sander must be re-added once before commissioning, and check whether the connection between the components is firm and reliable, whether there is any foreign matter on the impeller, and whether the motor wiring is correct. After the operation, if there is any abnormality, stop running immediately.
