To avoid the damage to the natural ecological environment caused by excessive river sand mining and protect the existing river sand resources, the use of machine-made sand is becoming more and more frequent. So what is the difference between making sand with stones and river sand? Is the investment in stone sand-making machines big? Let me introduce myself to you below.
Machine-made sand is the sand produced by machine crushing and sand-making, and river sand is formed by natural scouring and sedimentation. The raw materials and production equipment of machine-made sand are different, and the quality of the machine-made sand is different, and the river sand is formed for similar reasons, and the gradation hardness is not very different, so the high-quality machine-made sand can completely replace the river sand for construction aggregates middle.
River sand is a non-renewable energy source. Due to years of mining, river sand reserves are becoming less and less, supply is in short supply, and prices have skyrocketed; while machine-made sand is produced with sufficient raw materials, river pebbles, cobblestones, granite, construction waste, gravel tailings, gravel, etc. It can be used as raw material for the production of machine-made sand.
The material characteristics mainly refer to the firmness and durability of the stone. The firmness of the machine-made sand is worse than that of the river sand, but it can still reach the high-quality product index of the national standard, and it is no problem to use it in ordinary concrete. The quality requirements are high, admixtures can be added to the machine-made sand, and the crushing index and stone powder content of the concrete can be controlled at the same time.
After understanding the difference between machine-made sand and river sand, the stone sand making machine must be what most users want to know, so is the stone sand-making machine a big investment? This also depends on the actual choice of the user.
1. There are more than one type and model of stone sand-making machines. Different types of sand-making machines have different costs. The larger the model of the sand-making machine, the greater the output at that time, the higher the production cost, and the higher the equipment quotation.
2. There are many manufacturers of stone sand-making machines in the market. Different manufacturers have different production materials and technical levels, which will also lead to different quotations for stone sand-making machines.
With the development of the ore industry, the quality of sand-making equipment and production technology has gradually improved, and stone sand making has become more and more common. Sand is very necessary.
