Introduction to the Third Generation Sand Making Machine

The third generation sand making machine is also called a counterattack high-efficiency sand making machine. The Zz new generation high-efficiency sand making machine is developed by absorbing and digesting Xx technology inside and outside Gg, combined with specific industrial and mining conditions in Gg related industries, and is used for the fine crushing of various medium hardness solid materials; Widely applicable for fine crushing of various minerals such as granite, basalt, limestone, river pebbles, cement clinker, quartz, iron ore, bauxite, etc. It is also used for the production of high-quality stone materials in industries such as artificial sand making, high-grade highways, railways, water conservancy, airports, construction, cement, refractory materials, and metallurgy. The counterattack high-efficiency sand making machine has the characteristics of small discharge particle size, uniform particle shape, large production capacity, long hammer life, small matching power, transforming three-stage crushing into two-stage crushing, simplified process, simple structure, easy maintenance, and smooth operation. The third generation sand making machine (counterattack high-efficiency sand making machine) is a new generation of energy-saving sand making machine.（Third generation sand making machine

Characteristics of the third generation sand making machine

The third-generation sand making machine has the characteristics of small discharge particle size, uniform particle size, high production capacity, long hammer life, low matching power, transforming three-stage crushing into two-stage crushing, simplified process, simple structure, easy maintenance, sand making and shaping function, and smooth operation. The sand produced is cubic and meets the requirements of Gg's infrastructure. The third generation sand making machine is a new generation of energy-saving sand making machine.

The specific characteristics and advantages of the third-generation sand making machine are as follows:：
novelThe device has stable and reliable operating performance, simplified process, simple and reasonable structure, and is compact, making it easy to replace parts and maintain. Easy maintenance and convenient mobility. Transforming from tertiary crushing to secondary crushing has high production capacity, long service life of the hammer head, environmental protection and energy saving, and is widely suitable for fine crushing of raw materials such as granite, basalt, cement clinker, quartz, diamond sand, mineral sand, iron ore, aluminum vanadium soil, especially river pebbles. It overcomes the disadvantage of traditional sand making equipment that is only suitable for soft rock (150MPa) raw materials.
uniqueThe third-generation sand and gravel dual-use machine (third-generation sand making machine) can produce both sand and stone materials. Unique structure of high chromium plate hammer, unique counterattack lining for hard rock fragmentation, unique inertial impact balancing device, and unique and easy disassembly and maintenance window. The particle size of the discharge can be adjusted, simplifying the crushing and sand making process.
EfficientThe third generation sand making machine has a 30% to 50% higher yield rate than traditional sand making machines of the same scale (with a yield rate of ≤ 5mm accounting for over 85%).
Power savingThe third-generation sand making machine saves 50% to 70% of electricity compared to traditional sand making machines of the same scale (produced with just one motor).
High qualityThe third-generation sand making machine produces finished sand and stone materials in a cubic shape with strong compressive strength, suitable for high standard building needs (needle shaped, less flaky).
save moneyThe third-generation sand making machine saves 50% to 60% in equipment investment compared to sand making machines of the same scale. (Can be produced on a single machine)
maintenanceThe maintenance of third-generation sand making machines is reduced by 50% to 60% compared to sand making machines of the same scale. (Vulnerable parts can be purchased locally)

Supporting facilities

The third-generation sand making machine reduces equipment by 30% to 50% compared to traditional equipment of the same scale. (Reduce one to two jaw crushers)

Working principle of the third generation sand making machine

The third-generation sand making machine is a continuous operation equipment. When the machine starts working, it must first ensure that there is no material in the crushing chamber of the sand making machine before starting the motor. Under the drive of the motor, the rotor in the crushing chamber rotates at high speed, and the material enters the Yy crushing chamber and collides with the plate hammer on the rotor for the first time to crush the stone. The stone falls into the second crushing chamber for the same crushing process. When the crushing particle size meets the requirements, the stone will be discharged from the discharge port through the grate and transported to the next process by the conveying equipment.
The particle size of the stone can be controlled by adjusting the width of the discharge groove.

Common knowledge of maintenance for third-generation sand making machines
To ensure the efficient and stable operation of the third-generation sand making machine, regular maintenance and upkeep should be carried out. The following is the daily maintenance knowledge provided by Qingshan Technology for sand making machines.

1. The tightening force of the transmission triangular belt of the sand making machine should be adjusted appropriately to ensure uniform force distribution of the triangular belt. When driven by dual motors, the triangular belts on both sides should be grouped and selected, and the length of each group should be kept consistent. The difference in current between the two motors should be adjusted to not exceed 15A.2. Regularly shut down and open the observation door to observe the internal wear of the sand making machine, including the wear degree of the central feeding pipe, cone cap, upper and lower flow channel liners of the impeller, circumferential guard plate, and wear-resistant block. After wear, they should be replaced or repaired in a timely manner. When replacing the wear-resistant block, it should be replaced at the same time to ensure that the weight of the wear-resistant block is the same.

3. During the work process, special attention should be paid to safety as the sand making machine is a high-speed operating equipment. Staff should stay away from the equipment. If repairs are required on the machine, the power must be cut off before operation.
4. Add an appropriate amount of lubricating grease to the sand making machine every 400 hours of operation. After 2000 hours of operation, open the spindle assembly to clean the bearings. Generally, after 7200 hours of operation, replace the bearings with new ones. The upper bearing of the spindle assembly is the floating end, and the lower bearing is the fixed end. After assembly, the pulley should rotate flexibly when manually pulled.
Tips
：At present, the sand making machines introduced by ZzXx in the world are third-generation sand making machines and impact sand making machines, which work on the principles of counterattack and impact respectively, so they are also known as counterattack sand making machines and impact sand making machines.The impact sand making machine is a second-generation sand making machine product, which works by impacting "stone to stone" and "stone to iron",
