Sand Maker is a high-efficiency rock crushing equipment with home and international leading level; the machine is developed by introducing the crushing theory and technology from Barmag Company of America and combining the actual situation of sand making. It is widely used for crushing hard and crispy materials, such as rock, grinding material, refractory material, cement clinker, quartzite, iron ore and concrete aggregate; and it is especially suitable for the sand and sandstone making for construction and road paving.
Although the sand and stone manufacturing industry rely on the application of new type equipment such as impact crusher and sand making device and the production capacity has been improved significantly, the number of the other industries that advance into the stone and sand market is very large, different knowledge and superficial comprehension to this field, there are a lot of problems existing in this field:
(1)The quality of many stone and sand products is very low which has a bad influence on the quality of the concrete. The low quality of the stone products leads to the low quality of the concrete to a great extent.
(2)The implementation and surveillance of the standard of this industry is not strict. No one carries out the standards, nor supervise them, which lead to vicious circle to a great extent and the quality and the stone product cannot be improved.
(3)Many people misunderstand or know little about this industry.
(4)The customers and even the manufacturers do not know completely the effects of the sand aggregate so that they cannot take the initiative to improve the product quality.
(5)The consumption of the resources is huge. As a resource-dependent industry, huge resource consumption does not shows in this industry, so if you want to gain more economic benefits with less cost, you will have to solve this problem fundamentally.
Resource shortage and environmental protection enhancement are problems that many places are faced with. As a professional sand maker and professional vibrating screen manufacturer, according to many years’ experience specializing in the research and development of the stone and sand products and the results that survey and research recently, Hongxing Machinery thinks that exploitation of the mining tailings and artificial sand is the important way to replace the building-used sand and this way we can solidify and develop environmental protection and increase the resource use rate.
