1) The crushing chamber of the constant speed vertical shaft impact machine can be "stone to iron" or "stone to stone". There is no qualitative change, only quantitative change. The sand production of the former is higher than that of the latter, but the grain size of the sand is slightly worse, the content of stone powder is more, and the anvil is worn more. For the difference between "stone to stone" and "stone to iron", please refer to "2 crushing methods and 2 feeding methods of the sand machine. The wrong selection will greatly affect your production efficiency!". 2) The crushing chamber * of the high-speed vertical shaft crusher is "stone to iron", and the feeding amount is lower, because the small particle size and light weight of 5~2.5mm stone must obtain more effective collision capacity in order to crush it. 3) The vertical shaft impact with two speeds is used to break the sand, and the particle size of the high-speed crusher feeding material is appropriately increased, which can further increase the content of stone powder in the finished sand to

With the depletion of natural sand resources in recent years, artificial sand came into being under the market demand and has been used more and more widely. Although the artificial aggregate processing has a history of decades, how to correctly select the production process to ensure the reliable operation, advanced technology, and reasonable economy of the processing system is still an important problem faced by the design of the artificial aggregate processing system. This article introduces four sand making processes that are widely used at present. 3. Sand making process combined with vertical shaft impact crusher and rod mill In order to solve the problems of low medium diameter sand content and increase production in the sand making process of vertical shaft impact crusher, the sand making process combined with vertical shaft impact crusher and rod mill is adopted. The process flow is as follows: after the stone is crushed by vertical shaft impact crusher, it enters into the screening machine for grading, and the stone ＞ 5mm

With the depletion of natural sand resources in recent years, artificial sand came into being under the market demand and has been used more and more widely. Although the artificial aggregate processing has a history of decades, how to correctly select the production process to ensure the reliable operation, advanced technology, and reasonable economy of the processing system is still an important problem faced by the design of the artificial aggregate processing system. This article introduces four sand making processes that are widely used at present. 1. Vertical shaft impact crusher sand production process At present, most projects in China use vertical shaft impact crusher as the main production equipment for sand production. Whether the crushing chamber is "stone to stone" or "stone to iron", its production process is "feeding crushing screening return (or warehousing)", The flow diagram is as follows (2.5mm, 5mm and other examples are given below for easy explanation
