Sand and gravel is an indispensable key material in the construction field. Especially when natural sand and gravel continue to decrease, machine-made sand has become a substitute for natural gravel, and sand making equipment has become a necessity. Therefore, there are many related sand making equipment on the market. What details should be paid attention to in the selection of river pebble sand making machine? Targeted selection can ensure the of the equipment and improve the overall efficiency and profitability. What details should be paid attention to when selecting equipment? 　　 1. The hardness of river pebbles cannot be ignored
　　The hardness of each material is different. River pebbles are harder materials, so it is necessary to select special equipment for the hardness of river pebbles. Ensure accurate crushing effect and quality. The higher the hardness, the larger the crushing ratio of the selected equipment needs to be. If the crushing needs cannot be met, it will be difficult to ensure the crushing quality, and it may cause equipment damage and unnecessary losses.
　　2, output demand cannot be ignored
The choice of 　　he pebble sand making machine also needs to consider the demand for output. According to different output requirements, the suitable equipment selection is also different. There is a big gap in the amount of crushing and operation efficiency of various equipment. Therefore, we need to pay attention to the demand for output and select the appropriate equipment according to the hourly crushing volume, which can not ensure the increase of revenue, but also avoid the losses caused by improper equipment selection.
　　3, the output particle size is the key
　　The important choice of sand making equipment is the control of the discharge particle size. Different types of equipment can adjust different discharge granularity. Choosing equipment with a variety of discharging granularities makes the operation more convenient. Both coarse-grained requirements and fine-grained requirements can be adjusted and controlled, which can effectively save unnecessary equipment costs and ensure that the quality of the output particle size is more uniform.
