Introduction to the Sand Maker
The Sand Maker, also known as the Impact Crusher, has replaced the traditional equipment, such as the Hammer Crusher, the Roll Crusher, the Rod Milling Machine, etc. It proves to be the most essential equipment in the sand making industry. The Sand Machine in our company is developed by introducing the 'stones crush stones' working principle and technology from the United States and combining the actual domestic sand production conditions which makes it the leading high efficiency sand making equipment at worldwide level.
Our company provides mainly three types of sand making equipment: the VSI5X Sand Making Machine, the VSI Sand Making Machine and the PCL Sand Making Machine.
1. The VSI5X type combines three modes into an organic whole. It is the core equipment in industries, such as architecture, mining, metallurgy industry, highway, railway, bridges, water and electricity, mineral powder milling field and manufactured sand industry both at home and abroad.
2. The VSI type is the prior choice when selecting the whole system of sand making machines, widely used in highway, railway, high buildings, municipal engineering, hydropower dam construction and concrete mixing station. It can provide high quality manual sand aggregate, sand and stones.
3. The PCL System Sand Making Machine is widely used in all kinds of ores, cement, refractory materials, bauxite clinker, iron, carborundum and glass raw materials of high-hardness and super- hardness for medium and fine crushing.
Working Principle of the Sand Maker
The materials falling to the Sand Making Machine are divided into two parts by the distributor, with one part getting into the high-speed rotating impellers through the distributor, which are accelerated quickly in the impellers, reaching 100 times the acceleration of gravity, and then cast at the speed of 60 to 70 m/s from the three distributed passageways of the impellers and impacted by the materials falling around the distributor. Then they are impacted together with the lining in the cavity. Rebounded by the lining, those materials are sent obliquely upward to the top of the vortex cavity, and then they change the direction with a downward deflection, making a continuous material curtain. Therefore, the materials are impacted and crushed constantly in the vortex cavity. The crushed materials are discharged from the bottom port forming a closed circuit with the screening system. Generally, three times circulation can reach the granularity of 20 meshes. During the whole process, the materials are mutually impacted instead of contacting with the metal components, thus reducing the pollution and abrasion of the machine. Moreover, the self circulation of the air in the vortex cavity eliminates dust pollution.
This machine is the newly developed equipment in the 1990s for medium and fine crushing, which is also widely used one for replacing cone crushing machines, roller machines and ball mills.
