Vertical shaft impact crusher is a high-quality sand making machine for sand making and shaping, which utilizes the crushing principle of stone hitting stone and stone hitting iron for material crushing. Vertical shaft impact crusher is not only well used in the domestic situation, it is also very popular in foreign countries, is very popular with the users of a kind of sand making equipment, it is not only high yield, good quality of the output material, for construction and other aspects of the sand is a very good piece of equipment, then in the production capacity of the production capacity in the end how much of an advantage, the impact of these factors are mainly in what areas?
First, the impact of production line design
An efficient sand production line requires not only efficient sand making equipment, but also coarse, medium crushing, screening and washing equipment, waste water and mud treatment equipment to meet the capacity requirements. If a certain link does not meet the required crushing rate, will inevitably cause pressure and restriction to the next crushing level, which will lead to an increase in system failure points, which will reduce operational reliability, and ultimately reduce the amount of sand sand production sand making machine number will also decline.
Second, the impact of material characteristics
(1) material hardness
The main factor affecting the ease of ore crushing in the production process is the hardness of the ore itself.
Most of the mechanical properties of the ore material distribution is not uniform. With a large size and many texture gap material has poor mechanical strength and easy to fracture. The smaller the particle size, the smaller the internal textural gaps, the higher the mechanical strength and the less likely it is to fracture. The harder the ore, the higher the density, the greater the difficulty of crushing, the lower the efficiency, the more serious the wear and tear of equipment.
2) Input particle size and reasonable feeding amount
Each equipment defines the maximum particle size of the feed material. If it is too large, it will easily cause blockage and the equipment will lose its crushing function. Too much fine powder contained in the material will also affect sand making. For materials with a high content of fines, please sieve and screen them beforehand to avoid affecting the normal operation of the equipment.
While ensuring the output, the proper feeding amount is conducive to prolonging the life of wearing parts. When the feeding volume reaches 70%~90% of the full load of the impeller, the sand output reaches the peak. If the feeding amount is too small, not only the output of the equipment is reduced, but also the wear and tear of the crushing chamber liner increases, and the replacement cycle of the parts is shortened.
3) Material moisture
That is, when the moisture contained in the material is large, the material is easy to adhere in the impact sand making machine, and it is also easy to cause clogging in the process of downstream material transportation, which causes a reduction in the sand output capacity. If the humidity of the selected material is too large, sunlight or air drying can be used to reduce the percentage of moisture in the material.
4）Material viscosity
The greater the viscosity of the material, the easier it is to adhere. Materials with high viscosity in the impeller will adhere to the inner wall of the runner cavity, or even block the runner, which will affect the efficiency of the crusher if it cannot be cleaned up in time, and in serious cases, it may also affect the normal operation of the crusher. Therefore, when choosing materials, the viscosity should be low.
Third, the influence of working parameters
Crusher performance and structural factors have a great impact on crushing. The type and specification of the crusher, the economic rationality of the installed power, the appropriate range of rotational speed, the size of the discharge and the structure of the crushing chamber form have a great impact on the crushing efficiency.
For example, the crushing chamber of a vertical shaft impact crusher can be of the "stone to stone" type or "stone to iron". The former has better grain shape and is suitable for shaping. The latter has a high crushing efficiency but a slightly poorer grain type. Wear and tear costs for the peripheral shielding are also high.
Changing the form of the peripheral liner in the crushing chamber, or increasing the counterattack iron plate, increasing the size of the crushing chamber discharge, etc., can increase the output and increase the number of fine particles in the pellet. Significantly increased.
Fourth, the impact of impeller speed
Continuous material into the high-speed rotating impeller, accelerated to form a constant flow of power material, in the vortex cavity to produce high-speed extrusion, grinding and crushing, to get continuous crushing production. From the working principle of Vertical Shaft Impact Crusher, it can be seen that when the size of the material has been determined, with the increase of the crusher rotor speed, the kinetic energy increases greatly; when the crusher rotor speed is equalized, if the material quality increases, the kinetic energy also increases, and vice versa.
There is a certain relationship between the particle size of the crushed material and the rotor speed of the vertical shaft impact crusher. Under the premise of the same working condition, if the particle size of the crushed material is large, the linear speed of the crusher rotor is low. Thus, it can be seen that when the crushing strength of the material is large or the crushing size is small, the crushing speed needs to be increased. In the case of the same size of the material, moisture content, the same amount of feed, appropriately increase the speed of the crusher rotor (linear speed), the output of fine powder materials to improve.
Fifth, the operation and maintenance factors
The standardized operation and regular maintenance of the sand making machine will also affect the sand output of the equipment. If a sand making machine in the operation of the operation is not standardized and do not do regular maintenance, will cause wear and tear of the equipment to speed up the wear parts, so that the life of the equipment is greatly reduced, and in the unit of time the production is smaller.
For example: the continuity and uniformity of the feed to the production of a greater impact, continuous and uniform feed can make the production of normal, but also to improve productivity; feed particle size will also have an impact on the production of materials greater than the provisions of the impeller will cause the imbalance of the impeller and the impeller is too much wear and tear, based on the cause of the impeller channel and the center of the impeller into the tube, so that the sand making machine can not work properly, and so on.
Vertical shaft impact crusher is a widely used sand making equipment in the market. Its capacity is not only related to the equipment itself, but also closely related to the materials, operation and maintenance as well as the configuration of the production line. Users should add more comparisons at the early stage of purchase and choose a regular and strong manufacturer to plan and design the production line.
