Introduction of cobblestone sand making line

With the rapid development of national construction, the amount of sand is increasing, while the natural sand resources are increasingly short, obviously can not keep up with the construction needs, so the development of machine-made sand has become one of the important means to solve the shortage of sand, replacing natural sand with machine-made sand will become a new trend of future development.

There are many raw materials for the production of machine sand, such as pebbles, basalt, granite, bluestone, and other medium hard stones can be used to make sand. In China, cobblestone has become the main raw material of machine-made sand because of its abundant resources, low cost, and better appearance and quality than sand made from other broken stones.

At present, most cobblestone sand making line mainly adopts dry sand process, namely: feeding - crushing - sand making - screening. The cleanliness of the finished product is not only low, but also easy to cause serious dust pollution.
A few sand making lines adopt the wet sand process, namely: feeding - crushing - sand making - sand washing - sewage treatment. The resulting product has high moisture content and low sediment yield.

According to the characteristics of pebbles and many years of experience in sand process research, our company independently researched, developed, designed and manufactured rod grinding sand making machine for pebbles sand making. This set of equipment has been officially put into use in Hebei, with good operation and remarkable effect. Compared with other sand making equipment, it has the following advantages:
1. High efficiency and energy saving: energy saving 40-50% than traditional sand making machine;
2, grinding and crushing more uniform, over crushing light, high yield;
3, safety and environmental protection: the whole process does not produce dust or little dust, reduce the harm of dust to human body;
4, stable operation, low maintenance cost.
The rod grinding type sand making machine is also suitable for making abrasive, refractory materials, cement, steel sand, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregate and other hard and brittle materials of fine and medium crushing, is a kind of efficient, energy-saving gravel sand making equipment.
In recent years, our company focuses on the research of sand making process equipment, accumulated experience and continuous innovation, forming an industrial structure model from process design to equipment production and manufacturing, installation and debugging, which can solve a series of problems from project consultation to post-maintenance for users, providing users with reasonable process design and excellent products.
