Is it difficult to find a sand and gravel factory site? What if there are not many raw materials for processing sand and gravel? The local environmental protection policy is relatively strict, the production is unstable, and the investment in large-scale sand making equipment is too large. How to solve it? Nowadays, many friends who are new to the market, or who want to enter the market, are more and more inclined to small-scale production in terms of equipment selection. City, to protect economic interests. So if we want to meet these needs, we need to use a small sand making machine for the production of sand and gravel. What are the specific types of small sand making machines? Which small sand making machine is better to choose? Today, Xiao Mine will introduce it to you.
1. What are the small sand making machines?
1. Roller sand making machine
The counter-roll sand making machine is one of the most used sand making machines in the market. The sand processed by the counter-roll sand making machine has fine particle size, cleanliness and few impurities, which can be used to produce construction sand. The double-roller sand making machine also has the characteristics of low noise, less dust, compliance with environmental protection standards, and long wear cycle of equipment roller skins. It is a relatively durable and easy-to-use equipment in the field of small sand making.
2. Compound sand making machine
The compound crusher is a fine crushing equipment without screen bars, which can crush stone and can also be used to make sand. It is mainly suitable for processing limestone, clinker, coal, and other materials whose compressive strength is not more than 140 MPa and humidity is not more than 15%. The compound crusher has the characteristics of large crushing ratio, single equipment can make sand, and the price is cheap.
3. Impact crushing sand making machine
Impact sand making machines are widely used in the field of machine-made sand. Perhaps our knowledge of production capacity remains at the medium and large level, but there are many types of impact sand making machines, which can also meet the production needs of small-scale sand making. The impact sand making machine can not only make sand, but also has the function of shaping. During production, there is less dust, less noise, and the body is wear-resistant and durable.
2. Which small sand making machine is better?
The sand processed by the roller sand making machine is fine and clean, but the disadvantage is that it contains a large amount of powder. The compound crusher has a large crushing ratio, and a single unit can complete sand production. Impact crushing sand, the grain shape of the sand is good, but the relative price is high.
In general, these types of small sand making equipment have their own characteristics, and which one to choose depends on our needs.
