The whole process of processing stones into sand is called sand production line. The sand production line mainly uses the mined stone or tailings, which are coarsely crushed by a jaw crusher, finely crushed by an impact sand maker (or impact sand maker), and the required particle size is obtained by a vibrating screen, and the unqualified particle size is finely crushed back to the sand maker by a belt conveyor. If necessary, you can add a sand washer to clean the impurities in the stone. Compared with natural sand, machine-made sand has the following differences and advantages: machine-made sand washing material is excellent and stable. Machine-made sand washing is a hand-selected raw material, which is uniform and stable, and its mineral composition and chemical composition are consistent with those of raw materials, unlike natural sand. The sand is clean, free of mud and other harmful impurities, and its performance is stable. Good particle size classification. One kind of machine-made sand washing, one fineness modulus, only corresponds to one gradation. Its fineness modulus has a linear relationship with the screen allowance of a single screen. As long as the linear relationship is established and the screen allowance of a single screen is measured, the fineness modulus can be calculated accurately and quickly. However, the fineness modulus of ordinary natural sand can be graded in many ways. The fineness modulus can be artificially controlled through the production process, and the production can be organized according to the requirements of users, which is impossible for natural sand. The third generation sand making machine is also called the impact high-efficiency sand making machine or fine crusher. It is the latest generation of high-efficiency sand making machine developed by absorbing and digesting the advanced sand making machine technology at home and abroad and combining with the specific industrial and mining conditions of domestic mining machinery industry, and is used for finely crushing various solid materials with medium hardness; It is widely used for finely crushing granite, basalt, limestone, river pebbles, cement clinker, quartzite, iron ore, bauxite and other minerals. At the same time, the impact high-efficiency sand making machine is also used to produce high-quality stone in artificial sand making, high-grade highway, railway, water conservancy, airport, construction, cement, refractories, metallurgy and other industries. Impact sand making machine (hereinafter referred to as sand making machine) is a kind of self-impact crusher of materials. It is a high-energy and low-consumption sand-making equipment with international advanced level developed by our company by introducing advanced technology of similar products from abroad. It is the most advanced and ideal medium, precision and molding equipment at home and abroad. It is widely used for fine grinding and coarse grinding of metallic and nonmetallic ores, cement, refractories, abrasives, glass raw materials, building aggregates, artificial sand making and various metallurgical residues, especially suitable for medium-hard, superhard and abrasive materials such as silicon carbide, emery, sintered bauxite and magnesium oxide. , superior to other types of crushers. Used with hydraulic jaw crusher, it can treat all kinds of metallurgical slag, especially suitable for building sand and road sand. The circular vibrating screen of Huibang Heavy Industry makes circular motion, which is a new type of multi-layer and efficient vibrating screen. Circular vibrating screen adopts cylindrical eccentric shaft exciter and eccentric block to adjust amplitude, which has long material screening line and many screening specifications. It has the characteristics of reliable structure, strong vibration, high screening efficiency, low vibration and noise, firmness and durability, convenient maintenance and safe use. Circular vibrating screen is widely used in product classification in mining, building materials, transportation, energy, chemical industry and other industries. Belt conveyor is short for belt conveyor. The belt conveyor uses the continuous or intermittent movement of the conveyor belt to convey various articles with different weights, which can not only convey various bulk materials, but also convey various small goods such as cartons and packaging bags. It is widely used. The conveyor belt of belt conveyor is made of rubber, silica gel, PVC, PU and other materials, which can be used to convey ordinary materials and meet the special requirements of oil resistance, corrosion resistance, antistatic and other materials. Special food-grade conveyor belt can meet the requirements of food, pharmaceutical, daily chemical and other industries. PL sand making machine is a kind of special sand and gravel production equipment, which saves 50% energy compared with traditional sand making machine. All kinds of rocks, ores, limestone, basalt, granite, pebbles, river pebbles and other stones can be made into building sand with various particle sizes. The sand has uniform particle size and high compressive strength, which is far more in line with building requirements than natural sand and sand produced by ordinary hammer sander, and can improve building quality. The equipment has the characteristics of reliable performance, reasonable design, convenient operation and high working efficiency. The artificial gravel production line passes through the feeder, jaw crusher and crusher, and then enters (sand making machine and impact crusher) respectively, and the required stones of various specifications are obtained by vibrating screen classification, and the sand is obtained by efficient sand washing machine. Equipment required for machine-made sand production: feeder, jaw crusher (general equipment), belt conveyor, sand maker (PL sand maker is the most advanced), vibrating screen (two floors and three floors) and sand washer (wheel bucket type and spiral type).
