The use of sand making machines has a long history. In the long-term development process, the sand making technology has been continuously updated and improved. Today, there are many types of sand making machines on the market with different performances, making it difficult to choose. To ensure the production quality of machine-made sand, it is particularly important to choose the appropriate sand-making equipment. When choosing sand making equipment, the actual production situation of machine-made sand should be the main consideration, and at the same time, it should be comprehensively considered in combination with the quality requirements of finished sand, production requirements and the properties of raw materials.
At present, the widely popularized sand making machines in the market include hammer sand making machines, jaw crushers, counter-roll sand making machines, and vertical impact crushers. Due to the variety of models of sand making equipment, it will bring many difficulties to consumers when choosing.
The main working principle of the hammer sand making machine is that the rotor with the hammer head is crushed by the high-speed motion to strike, impact, shear and grind the stone. The whole sand making process is smooth and simple without clogging, and the effect is remarkable. Sand, beneficiation, cement, metallurgy, chemical industry, building materials and other fields, the finished product has obvious advantages in grain shape, and it is a mining equipment widely used in stone crushing and shaping.
Hammer sand making machine performance
Advantages: 1. The structure is compact and reasonable, and the production capacity is guaranteed; 2. The unique dust-proof sealing structure prolongs the service life and can alarm in time in an emergency; 3. The unique crushing cavity shape, the finished product has excellent particle shape and high gradation , It can reduce needle-like stones, etc., and the discharge is stable; 4. It has hydraulic lock and hydraulic adjustment functions, easy to operate, and also has iron release function and cavity cleaning function, which is safe to operate.
Disadvantages: The shaping effect of the hammer sand making machine is "slightly inferior", but it can meet the disposal needs of many consumers, and the cost performance is enhanced. If the raw stone is large, it needs to be formed once, from large stones to small sand. , The processing capacity is more limited. According to the difference between the raw stone and the finished product, the processing capacity of the hammer sand making machine ranges from 50T/H-900T/H.
Jaw Crusher
Jaw crusher, referred to as jaw crusher, is mainly used as a primary crusher and a secondary crusher to crush various ores and bulk materials with medium particle size. It is widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. . The maximum compressive strength of the crushed material is 320MPa. The performance characteristics are large crushing ratio, uniform product particle size, simple structure, reliable performance, easy maintenance, low operating cost, and it is not easy to block ores with high moisture and high viscosity. Disadvantages: low productivity, large power consumption, large vibration, small crushing ratio, uneven product particle size, and can not be crowded into the mine.
When choosing coarse crushing equipment, a comprehensive analysis and comparison should be carried out according to different situations. Generally, large-scale concentrators use coarse crushing cone crushers. Small and medium-sized concentrators, especially when dealing with viscous materials, should choose jaw crushers. Usually, the choice of crusher can only be determined after calculation and technical and economic comparison.
Roller sand making machine
Double-roller sand making machine is also called double-roller sand making machine. It is suitable for medium and fine crushing of ores and rocks below medium hardness, and is very suitable for the crushing of raw coal (including coal gangue) in large coal mines or coal preparation plants. It mainly relies on the driving device, which is driven by two motors, driven by a V-belt to the sheave, and drives the two rollers to rotate relative to each other to crush and crush the material.
The advantages of the roller type sand making machine are low consumption and good sand particles; the disadvantage is that the output is small and the yield is low.
Vertical shaft impact sand making machine is referred to as impact breaker, commonly known as sand making machine. It is a high-energy and low-consumption impact breaker with international advanced level. The most effective, practical and reliable stone crushing machine.
Mobile sand making machine
The mobile sand making machine is a product of the needs of the new era. Its main feature is that it can be operated in a mobile manner to meet various needs of coarse crushing, medium crushing, fine crushing, ultra-fine crushing and screening of complex construction waste. The mobile sand making machine can directly select the site, drive directly to the site, and directly reach the finished product size without transportation. It is especially suitable for small crushing sites, suitable for construction waste treatment and the production of machine-made sand. At the same time, the mobile crushing plant greatly reduces the investment cost, but increases the investment income. It is widely used in road and bridge construction, mining and urban construction.
The mobile sand making machine has the characteristics of reasonable matching of crushing equipment and sand making equipment at all levels, smooth discharge of the whole line, reliable operation, convenient operation, high efficiency and energy saving. In particular, it has good mobility, can be extended with the raw material or construction site, and can be combined in various ways to meet the needs of different materials.
The above introduces several commonly used sand making machines. With the development of the times, sand making machines can meet higher and higher standards of sand use and become indispensable production equipment in the construction industry. In the production process of machine-made sand, standardized sand-making plans and standardized sand-making equipment are the premise and foundation of high-quality production.
