Before selecting sand making equipment for a sand making production line, it is essential to determine the raw material source for manufactured sand production. The output, quality and grade of manufactured sand are largely determined by the sand making machine. Therefore, when selecting such aggregate crushing plant, it is crucial to understand the sand making equipment performance and the main application scenarios of the finished sand products before making a prudent choice.
Based on our experience, Ninon analyzes how to select sand making machine as follows:
Generally speaking, a two-stage crushing process can be adopted for three-grade coarse aggregate production, while a three-stage crushing process is required for four-grade coarse aggregate production. The aggregate crushing plant’s crushing stages are closely related to the grade of coarse aggregate, which is a key factor in selecting sand making equipment.
A key task of the sand making production line is primary crushing of materials. The most commonly used primary crusher in the aggregate crushing plant is the jaw crusher, which is widely applied for coarse crushing and mainly responsible for the initial reduction of stone materials. The stone materials after primary crushing by jaw crusher feature a low content of needle-like and flaky particles, making it an excellent supporting equipment for the sand making machine.
After primary crushing, the materials will be subjected to secondary and tertiary crushing. In sand making production lines, impact crushers and cone crushers are typically used for medium and fine crushing in the sand making equipment. Impact crushers are usually adopted for crushing soft rocks such as limestone, as they feature high capacity and can reduce the number of crushing stages of the aggregate crushing plant. For medium-hard rocks, cone crushers are generally the preferred choice for the sand making machine. When selecting sand making equipment, it is essential to first analyze the raw materials and understand their properties before equipment selection. Otherwise, it will cause unnecessary troubles in production and reduce production efficiency of the aggregate crushing plant.
With continuous improvement and optimization of sand making machines, there are currently two main types of sand making equipment: one is the vertical shaft impact crusher, and the other is the single vertical shaft impact sand maker. The vertical shaft impact crusher manufactured by Ninon, a core part of the aggregate crushing plant, features adjustable fineness modulus of the finished sand and delivers high-quality aggregates. The single vertical shaft impact sand maker, another type of sand making equipment, also produces high-quality sand at a low cost, but it is mainly applied for sand making from limestone and granite in the aggregate crushing plant.
Investors may select the appropriate sand making machine based on the characteristics of the aggregate crushing plant and their actual production conditions. Choosing the right sand making equipment will improve operational efficiency and reduce investment costs of the sand making production line.
