Detailed Analysis of Working Process of Double-rotor Impact Crusher


Double-rotor impact crusher is a type of Diamond Stone Jaw Crusher Manufecture India
that is widely used in many industries and its advantages are big crushing ratio, high processing ability, high working efficiency and low energy consumption. This paper will analyze its structure and working process in detail.
The double-rotor impact crusher is mainly composed by rack, first stage rotor, first stage impacting plate, divided-chamber impacting plate, secondary stage rotor, secondary stage impacting plate, adjusting spring, first transmission part and second transmission part.
The working process of this Crusher Machine & Grinding Mill is:
The two electro motors transmit through hydraulic coupling, spring coupling and triangle belt and drive the first rotor and second-stage rotor to rotate with high speed in the same direction. The plate hammer of the first-stage rotor and the first-stage impacting plate and the divided-chamber impacting plate form the first-stage crushing chamber; the hammer plate of the second-stage rotor and the second-stage impacting plate form the second=stage crushing chamber. The materials are fed into the first crushing chamber from the chain gate of the feeding mouth of upper rack, and after bring impacted by the plate hammer rotating at a high speed, the materials will be thrown to the first-stage impacting plate and the divided-chamber impacting plate along the tangential direction, and then the materials will bounce back to the space where the plate hammer rotates and continue this process. In this way, the materials will get many times of impacts by the plate hammer and the impact plate and mutual collisions and then the materials will crush along the bedding, joint and crack. After being crushed in the first crusher plant in india, the materials will go into the second crushing chamber where the materials will be impacted and hit by the second-stage rotor plate hammer and the second-stage impacting plate until the materials are crushed to the size of below 20mm, and then the materials will be discharged out of the machine.
In addition this crusher adopts chamber separation crushing principle, and the two rotors have a 265mm of height difference, so that the second rotor will be forced to feed materials so that the linear speed of the second rotor will be improved. In this way, two rotors will undertake their own crushing functions, thus improving the crushing efficiency.

Techniques and Characteristics of Artificial Sand Production


In China, artificial sand technologies have experienced 40 years of development and has achieved the advanced world level, from the step-by-step grope to continuous innovation and application. Compared with the natural sand, artificial sand has a variety of advantages in the aspects of system construction cycle, product quality, economical efficiency and impact on the environment. In the near future, Sand Making Machine will be bound to replace natural sand and truly become the granary of our engineering construction.
Artificial Sand Production Process:
1. The prospect of artificial sand replacing natural sand.
Currently the construction sand in domestic mainly comes from exploiting the natural river sand. But the natural sand is a kind of regional and non-renewable resource within short time. In recent years, the large-scale infrastructure construction driven by the high-speed economic development in our country has consumed a large amount of natural sand resources. Natural sand resources decrease rapidly in many areas of China. In many peri-urban areas and regions of some large and medium-sized cities such as Beijing and Tianjin, the natural sand resources has been nearly dried up so far. The exploitation and excavation of natural sand has a tremendous destruction to the riverway as well as a certain adverse effect on the natural ecology.
Nowadays, the progress in the fast-changing processing equipment for VSI Sand Making Machine and the development of theories such as self-impact crushing provide a solid technical foundation for artificial sand taking the place of natural sand. In the hydropower industry, artificial sand has nearly replaced natural sand in all uses, becoming the main ingredient of concrete. Various departments have started to study and promote the applications of artificial sand in more fields.
2. The production technique and equipment of artificial sand.
Artificial sand production process: Feeding system (feeder) — coarse crushing system (jaw crusher)– fine crushing system (cone crusher)– sand making system (sand maker/ rod mill)– aggregate washing system (sand washer)– sand screening system (vibrating screen)– finished product stockyard.
3. The Characteristics of artificial sand production technique.
To coordinate the development of artificial sand, we have studied the all-dry, semi-dry and wet-process sand production techniques. In the long-term production practice and constant research, we have worked out a major mode of sand production process according to the aggregate sources and quality requirements, that is, three-stage crushing(coarse, secondary or fine crushing) pluses the vertical shaft crusher.
4. Its main characteristics are as following:
1. Substitute crushing for grinding and combine crushing with grinding, more crushing than grinding;
2. Add coarse sand shaping and Sand making machine in the dry-process sand production to control the fineness of sand and rock powder content, etc.
3. Adopt computer-centralized control and video surveillance, conductive to less people on duty and system automation;
4. Pay attention to environmental protection and create a “green granary”, and choose different measures to control dust in different production stages, such as water spray, air draft and local sealing and etc.;
5. Recycle the production wastewater through the precipitating and circulating system.

Solutions of Some Uncommon Problems of Sand Dryer


In the previous articles, we have talked about some common problems of sand dryer. But how can we handle some uncommon problems of it? Many people who don’t have rich experience will feel puzzled. Fote Machinery, as a XSD Sand Washer which has rich experience in the dryer field, will analyze and give you some solutions of uncommon malfunctions.
1. The Leakage and Deviation Problems of Transmission Device and Their Solutions:
Faced with this problem, we should regulate and tension the screw rod. In the actual production, the operator of sand dryer should stop the machine and remove some sand from one side of transmission device or add some sand on the other side of it according to the sand storage in the tail of transmission device. Thus the leakage and deviation problems will be solved.
2. The Influence of Weather to Spiral Classifier’s Yield:
We had better operate sand dryer during fine days, in order to avoid the influences to its yield brought by rainy days. During the rainy days, we can arrange some maintenance work. In the sand yard, we should keep rain flowing out of it smoothly and avoid deposition. After rain, we should dry the sand with lower moisture content first to save energy and improve drying efficiency. At the same time, we should formulate a reasonable operating system for Sand making machine and strengthen training and evaluation of operators.
3. The Crack and Deformation of Inspection Door and Their Solutions:
The inspection door cannot be closed tightly once cracked or deformed. The best solution of it is to make a new type inspection door which is made up of common steel plate with a thickness of 4mm. the contact surface between the inspection door and fire is welded with riveting firmware and poured with water featured castable to avoid direct roasting from fire.
