1. What is construction stone? Why do sandstone stones make money?
Construction stones are mainly divided into two categories: crushed stone and pebbles. Pebbles are river pebbles or pebbles. After crushing, they are made into sand, which has a hard texture and good quality. Gravel will generally use sandstone, granite, quartz sand, basalt and other raw materials through mechanical processing to break the stone, this stone sharp, angular, is widely used in construction, roads, Bridges and other industries, is conducive to the bond between cement and concrete, market demand is very large.
Sandstone is formed by natural precipitation, is composed of small particles, its raw material cost is low, the main cost is transportation, labor, water and electricity, equipment and other costs, but the sandstone into building stones with: Sound insulation, moisture-proof, no cracking, no deformation, corrosion resistance, anti-damage and other super advantages, the sales price profit is considerable, according to incomplete statistics, a ton of net profit accounted for sales (gross profit) one-third, so profitable business how can not attract people love it?
2. What equipment is needed for building stones made of sandstone?
Sandstone into stone used in construction, must go through the production process of crushing, sand making, screen classification, a full set of crushing production line need to reasonable collocation, can achieve the small investment, high efficiency.According to the characteristics of sandstone, the following equipment should be prepared for building stones made of sandstone:
01. Coarse crushing -- jaw crusher;
Sandstone raw material is larger, generally need to be first through coarse crushing processing, jaw crusher is coarse crushing must equipment, the feed mouth is larger in 1200mm or less, crushing strength is strong, can be applied to all kinds of hardness materials, discharge adjustment range of 10-350mm, can be adjusted according to the needs of users.
02. Medium crushing -- cone crusher or impact crusher;
When the sandstone material is processed to below 560mm, cone crusher or impact crusher can be used directly:
Cone crusher feeding mouth, laminated crushing, uniform particle size, hydraulic cylinder automatically adjust the particle size, and has overload protection device, advanced technology, long wear parts replacement cycle, low maintenance cost.
Impact crusher is characterized by large feed mouth, fine discharge mouth, the finished product is cubic, better than the cone crusher finished product grain type, but for high hardness of material wear parts replacement fast, high maintenance cost, two pieces of crushing equipment have advantages and disadvantages.
03. Sand making -- impact sand making machine;
In order to increase the price of finished sandstone products, impact sand making machine is adopted, which is a professional equipment in sand making equipment, using the double crushing effect of "stone beating stone" and "stone beating iron", high output, good particle shape of finished products, high uniformity, reasonable grading, in line with the national standards for the use of sand, FM fineness modulus between 2.6-2.8.
04. cleaning sand -- sand washing machine;
The role of the sand washing machine is to effectively improve its sales price, and the value of the sandstone can only be fully reflected after cleaning. The wheel bucket sand washing machine has the characteristics of high cleanliness and green environmental protection. The motor and water wheel are designed separately to reduce water corrosion, realize water recycling and low sand loss rate.
05. auxiliary equipment -- vibration feeder, vibrating screen, transmission belt;
Vibration feeder, vibrating screen, transmission belt need to be tailored according to the user site, or reasonable order, can use sealed design, dust and noise reduction, green environmental protection.
3. "Sandstone into building stone equipment" how much? Can lead environmental protection?
Excuse me: "how much money is the sandstone building stone equipment?" The price is always the customer's concern, a sandstone stone production line 200,000-3 million, mainly according to the output size, the output of 30 tons, 50 tons, 100 tons, 500 tons or even 1000 tons, the size of the production capacity determines the equipment investment price.
SMMVIK Machinery company has strong strength, has rich experience in sandstone stone equipment, the price is fair and just, factory direct sales, for users to reduce the middle is the price difference, all the equipment of the company have obtained the national environmental assessment certificate, dust and noise points are qualified in the range.
