What are the main differences between stone crusher and sand making machine?
The crushing equipment produced by Shandong Sanxiang stone crusher plant is divided into the crusher series of crushing coarse materials and the sand making machine series specializing in the production of fine materials, coupled with auxiliary feeders, screening equipment, etc., which together constitute the complete product system of our company.
In reality, many stone crusher plant's friends do not know the difference between the crusher and the sand making machine, often confuse the two, so today, I will mainly tell you what the difference between the two is:
First: the definition of production is different. The production definition of the crusher is mainly born to produce various types of stones, powder and sand is only an accessory product, the main purpose is to extract stones. The production definition of the sand making machine is to produce machine-made sand, and it generally does not have the function of the crusher to produce stone.
Secondly: the materials to be broken are different. At present, the main crushing models used on the market include hammer crusher, impact crusher, jaw crusher and cone crusher, etc., which can be subdivided into head breaking machines and fine breaking machines, but the particle size of their crushing materials is generally much larger than that of sand making machines. Because the sand making machine is mainly used to produce machine-made sand, it determines that the particle size of the material to be broken is relatively small, and the material that is too large can not be broken directly, the general feeding particle size is controlled below 3 cm, and the smaller and more uniform the yield is higher.
Third: specific uses are different. Various types of crushers are generally the first process of the production of sand and aggregate, and sand production lines are often the second process. Now many stone crusher plants are combined to use the two, the first process occupied by the crusher is mainly used to extract the stone finished material required by the customer, the sand production line is often mainly used to eat the excessive material of the first process and the stone that the customer does not want, and the "waste" is made into mechanical sand.
Fourth: It works differently. The working principle of the crusher is mainly direct impact, counterattack, extrusion and other ways, which for limestone and other soft rock crushing mainly adopts the direct impact principle of the hammer crusher production line, such as granite, basalt and pebbles with high silicon content and high hardness, generally adopts the counterattack, backloading and other working principle of the jaw crusher, impact crusher and other models. The working principle of the sand making machine is mainly divided into punching type and rolling type, which generally have shaping function. For limestone and other soft rocks, you can use the impact type of counter plate hammer sand machine, crushing at the same time with shaping function. In the case of hard rock crushing, the roller grinding sand machine with rolling working principle can be used to save the wear cost of parts.
Fifth: the use of the finished materials of the two is different. Crusher production line is mainly used to extract stone, sand production line is mainly used to extract mechanical sand, in the actual production activities, the use of stone and mechanical sand has many different, but many times the two are combined together to use, the key depends on the user will use them for what. For example, paving, only stones and powder can be used, and in the daily production activities of the concrete mixing station, both are indispensable.
Sixth: the price positioning of the two is different. Generally speaking, the sand making machine is much more expensive than the stone crusher, although the time production looks lower than the crusher, but it is a fine material, so all aspects are more refined, and the price is relatively expensive.
Seventh: the stone crushing ratio of the two is different. The crushing ratio of the sand making machine is much higher than that of the crusher, which is also the fundamental reason why the sand making machine can not make sand and the crushing mechanism can not.
Eighth: accessories wear rate is different. Due to the relationship of the crusher, in the case of crushing the same material, the wear rate of the parts of the sand making machine is generally greater than that of the crusher, but it can not be generalized, but also depends on the specific model and working principle.
In summary: In fact, the difference between the crusher and the sand making machine produced by Shandong Sanxiang stone crusher plant is relatively obvious, mainly the production principle, function and use of the two are obviously different. So when you come to Shandong Sanxiang Heavy machinery to order machines, be sure to find out whether your crushing production line is mainly used to produce stone or mechanical sand, which is still very important.
