First, when purchasing a sand making machine, it is necessary to determine what minerals are used as raw materials for the sand making machine. At present, pebbles, quartzite, river pebbles, andesite and granite are the most commonly used sand and gravel materials. Because the hardness of each ore is different, you must choose professional equipment that can crush these ores when purchasing, such as the river pebble sand mill specially produced by the crusher factory, which is especially suitable for grinding stones with medium and high hardness.
Second, choose a new sand maker according to the ore particle size. Due to the different feeding capacity of various sand makers, the particle size of raw ore is also limited to some extent. Usually, it is necessary to use a large jaw crusher in advance. First, the large stones are crushed into appropriate particle size, and then they are crushed by a sand making machine.
Thirdly, choose the sand making machine according to the site of the sand making production line. Generally speaking, sand makers and other large crushers need to be installed on cement foundation piles. It is inconvenient to disassemble and transport. We must also find a suitable location. If the work site is not fixed, it is best to choose movable sand making equipment, such as mobile sand making machine, which combines the processes of crushing, sand making and screening into one to form a movable chassis car, which is no longer limited by the site and gives full play to the functions of the equipment.
Fourth, of course, it is more important to determine the manufacturer and price of the sand making machine, as well as the comprehensive use cost of product quality, after-sales service, transportation cost and quality after-sales.
The above four points summarize in detail the points you need to pay attention to when purchasing sand making machines. After all, the mining machine you choose needs to go through a long period of time with us, so you must buy it carefully.
