According to the existing sand making process, in fact, most of the stones can basically be used for sand making, such as pebbles, river pebbles, granite, basalt, limestone, etc., and even part of the industrial waste, solid waste and waste rock are used for sand processing. But what kind of stone is better for making sand? It is recommended to use pebbles, river pebbles, bluestones, granites and other stones with stable properties and hardness up to the standard as raw materials for sand making. Not only is there a large stock, but the effect of sand making is also very good, which is in line with national construction the standard of sand.
1. River pebble, basalt, granite, limestone, bluestone, etc.
These are common minerals with hard texture. They can be used as raw materials for sand and gravel in the sand and gravel production line. The sand made of basalt mixed with concrete can reduce the weight of concrete and has the effects of heat and sound insulation. It is a high-rise building. Good aggregates for building lightweight concrete, lime, granite and other crushed stone powder can be reused, etc., these are better alternatives to natural sand.
2. Sandstone, quartz sandstone, etc.
Sandstone is a kind of sedimentary rock, mainly composed of quartz and feldspar. Whether it is strength or grain type, it is one of the good raw materials for machine-made sand. In addition, its advantages such as outdoor weathering, non-melting in water, moisture resistance, and sound absorption are good buildings. One of the decoration materials.
3. Tailings, slag, construction waste, etc.
These originally existed as industrial wastes, but after sand making treatment, they can be used in construction, railway, highway and other industries. Concrete blocks, gravel blocks, bricks and tiles in construction waste are often used to crush them. Sand and gravel aggregates are used in construction, highway and other industries. Using them as raw materials to produce machine-made sand can save raw material investment costs.
What equipment is good for processing machine-made sand? The processing of machine-made sand is not only done by one piece of equipment, it requires a combination of multiple equipment to complete the entire sand making process. The equipment required is: jaw crusher (coarse crushing), impact crushing/cone crushing (medium crushing), Sand making machine (fine crushing), other auxiliary equipment (feeder, screening machine, conveyor), sand washing machine, dust removal equipment, etc. if necessary. Of course, if you want high-quality machine-made sand, you still have to talk about sand making machines. I recommend two sand making machines:
PLS series vertical impact crusher (sand making machine)
The self-developed sand making process adopts the crushing mechanism of "stone beat stone" and "stone beat iron", which can have sand making and shaping effects at the same time. The working mode can be divided into two modes: crushing sand making and high-speed fine crushing and shaping. The processed sand the size of the stone is below 5mm, and the size of the material is comparable to that of natural sand.
PFL series vertical complex crusher (sand making machine)
The vertical complex crushing mechanism sand machine has low cost and small investment. The product also has the crushing mechanism of impact grinding, and the equipment is formed at one time, no material return, no grate design, wet material can also be used for sand making, and the finished sand is beautiful. The selling price is high, and it is also very popular with customers in the market. This product can also be used for the crushing and processing operations of cement raw meal and clinker, and is an ideal fine crushing equipment for energy saving and consumption reduction.
