Mechanism Sand Making Technology Is Always in Improvement

20 years ago, many stone factories were mining through labor to pry the pieces of stone, and break the stones for building, which was really bot easy. So many places began to brick, and used brick as building material, although the intensity of brick is lower than natural stone, but also can solve house problems. However, old brick craft severely damaged the environment, and was banned again 10 years later. With the development of mining machinery and equipment, quarrying of gravel is already relatively easy, and modern crusher equipment can do assembly line work, so only a small number of observers and maintenance personnel are needed.

Stone production line was developed first, because at first the river sand resources were rich and mechanism sand did not receive sufficient attention. Stone has always been a popular building material in many industries, and the application from hammer breaker to inversed impact crusher was also a leap forward, so mechanism sand and aggregate technology has been in progress.

Mechanism sand was auxiliary product of impact crusher in the past, and there was not professional sand making machine or equipment, while the development of foreign sand making equipment system was obviously earlier than that of in China. Hongxing vertical shaft impact crusher is the beginning of real sand making technology and the backbone for promoting mechanism sand control technique. Hongxing vertical shaft impact crusher is a very good products designed based on the Barmak sand maker in United States. Since then, the mechanism sand and gravel equipment entered its gold age for 10 years. Meanwhile, wet sand making technology, dry sand making technology and mixed sand making technology had emerged.
