Vertical Shaft Impactor Crusher VSI Sand Making Machine Granite Basalt Sand Maker

Vertical Shaft Impactor Crusher VSI Sand Making Machine Granite Basalt Sand Maker Main Application:

Vertical shaft impact crusher is a kind of rock crushing equipment. It was applied in the 1980s and has the characteristics of stable and reliable work, convenient maintenance and high sand production rate. It is especially suitable for stone shaping and production mechanism sand. It can be widely used in fine crushing operations in hydropower, highway, construction, cement, metal mining and other industries.

Vertical Shaft Impact Crusher Categories:

According to the structure of the rotor, vertical shaft impact type sand making machine is divided into an open rotor structure and a closed rotor structure. For closed rotor structure, the rotor is caged, the material falls from the top into the closed rotor.

Sand Maker Sand Production Process:

Vertical shaft impact crushing mechanism sand has been used in large hydropower projects since the mid-1990s. The production processes include dry, wet and semi-dry methods. However, no matter what kind of production process is used, there are some disadvantages such as large sand fineness modulus and small median diameter, which seriously affect the quality of concrete and its poor adaptability to various concrete ratio requirements.

Most of the domestic projects use the vertical shaft impact crusher as the main production equipment for sand making. The form of the crushing chamber is “stone stone” or “stone iron”, and its traditional production process adopts “feeding→crushing→sieving→returning”. (or into the warehouse)".

According to the production process of Figure 1, the stone material is sent to the vertical shaft crusher by the feeder and the belt conveyor. After being crushed, it is sent to the screening machine for classification. The stones larger than mm are all returned to the transfer bin for circulation, 5~ The 2.5 mm stone material is divided into 2 channels: one returning to the transfer bin is broken by the crusher, and the other is entering the finished sand bin; and the stone less than 2.5 mm enters the finished sand bin or enters the spiral classifier to the finished sand bin. The production process is characterized by simple process flow and low energy consumption per unit; stone materials of 5 to 2.5 mm are subjected to repeated cycle crushing, and the crushing effect is poor, and the energy loss is slightly larger; 2.5 to 1.25 mm and 1.25 to 0.63 mm grains in the finished sand. The diameter of the stone is less; the control of the particle size of the finished sand is difficult (man-made factor control); the finished sand rate is low.
