What is the sand making process of the sand making machine?

sand making machine

The sand making machine production line can crush the widely distributed and abundant rocks into sand that meets the sand standard, which can be used instead of natural sand and relieve the tension of sand and stone. The following editor will introduce the process flow and equipment recommendation of the machine-made sand production line.

1. Preprocessing

If limestone, bluestone, river pebbles, granite and other sand-making raw materials contain too much soil and impurities, you can first sort the sundries that are not suitable for crushing, and remove waste wood, plastics and other sundries, so as to facilitate the next process. The processing process is carried out. If necessary, the raw materials can also be magnetically separated to remove scrap iron.

2. Raw material crushing

The vibrating feeder evenly feeds the raw materials into the coarse crushing equipment, and performs primary crushing on the raw materials. According to the hardness of the processed raw materials, the jaw crusher can be selected for coarse crushing. After coarse crushing, the materials with qualified particle size are transported to the The fine crushing equipment is further crushed, and those that do not meet the requirements are returned to the coarse crusher.

PE series jaw crusher: one-stage crushing equipment for coarse crushing of materials, simple structure, large output, small footprint and high crushing efficiency;

PY series cone crusher: secondary crushing equipment, for medium and fine crushing of materials with high hardness such as river pebbles, granite, basalt, etc., with good wear resistance, long service life, low production cost, energy saving and environmental protection, and is mostly used in large sand and gravel plants;

PF series impact crusher: secondary crushing equipment for medium and fine crushing of limestone, basalt, coal gangue and other materials with low hardness, low investment cost, adjustable particle size of finished materials, good particle shape, and small footprint.

3. Stone sand making

The finely crushed stone can meet the feeding requirements of the sand making machine. At this time, the sand making machine is used to finely crush and shape the material. The sand particle size after processing by the sand making machine is uniform.

VSI vertical impact sand making machine: two crushing modes of “rock hitting rock and rock hitting iron”, with stronger adaptability, high production efficiency, high degree of intelligence, stable and reliable operation of the equipment, and the function of shaping, and the output of sand and gravel The particle size is uniform, the gradation is reasonable, the particle shape is good, the sealing performance of the whole machine is relatively good, dust pollution is not easy to occur, energy saving and environmental protection.

4. Screening of finished products

Most sand screening processes use circular vibrating screens. According to user needs, the finished sand can be screened and classified into coarse sand, medium sand and fine sand after being processed by vibrating screens.

5. Sand cleaning

In order to improve the quality of finished sand, especially in terms of cleanliness, special sand washing equipment can be equipped after the sand making process to clean the sand.

DXS series bucket wheel sand washing machine/XL series spiral sand washing machine: Bucket wheel sand washing machine is commonly used at present. It is a new type of sand washing equipment with high efficiency. It has high cleaning degree, reasonable structure and large output. It is mainly used for Washing, grading and dehydration of machine-made sand, stone powder, mountain sand, river sand, etc.
