Why Use Mineral Sizer As a Crushing Unit In a Coal Crushing Project
Coal is the most important resource in the global energy, now is the largest use of all energy, the highest proportion, the most efficient energy, coal reserves are also the simplest, the lowest cost of important resources. The most important thing in coal mining is its crushing and conveying links. In many crushing equipment and crushing methods, mineral sizer takes the lead with its unique advantages.
The reason why mineral sizer is preferred in coal mining and coal crushing is that it has the following advantages.
1. Non-sticky and non-blocking. Exct mineral sizer in the design, the use of differential principle, that is, the use of different speed ratios of the reducer to drive the work, the formation of relative motion, so as to have the effect of mutual cleaning. This does not require the water and mud content of the broken material, which is especially suitable for use in cold areas and can effectively solve the problem of freezing in winter.
2. Screening, crushing function of one machine, the amount of powder is very low.
Mineral sizer’s two toothed rollers rotate inward so that the material less than the two toothed roller spacing is discharged directly without being broken, achieving the screening function, so as not to increase the amount of powder.
3. Change the traditional lubrication concept
The traditional lubrication concept is oil lubrication, the machine adopts automatic oil change lubrication, the lubrication effect is better, so that the service life of the bearing is greatly extended, up to more than 50,000 hours, further reduce the production cost.
4. Simplified structure and cost saving
Due to the mineral sizer working crushing teeth of exct, the spiral structure ensures that the material can be more evenly distributed over the length of the work roll, which can ensure that the larger material is broken into finished products by the mineral sizer machine to achieve a large crushing ratio, so as to achieve the simplification of the crushing system as much as possible.
5. Discharge particle size can be adjusted
The mineral sizer is designed with an adjusting device, which not only ensures the discharge particle size, but also enables the user to conveniently adjust the discharge particle size freely by adjusting the distance between the lower working payment according to the process needs. And through the adjustment of the lower working pay, the service life of the tooth plate can be greatly improved, thereby reducing the maintenance cost of the equipment.
6. With self-protection function
Many users’ materials contain more or less impurities and ultra-hard objects, which is difficult to completely remove, which requires that in the material crushing process, mineral sizer has a self-protection function, and there will be no damage to the main parts of the equipment when entering a small amount of ultra-hard objects. Therefore, exct mineral sizer in the design, fully take into account this situation, we designed a triple protection device, in addition to through the electrical control system to the motor for overcurrent, overload protection, but also specially set the work stall protection device, while the spindle is made of high strength, high toughness material. And make the spindle speed control in a lower range. When a small amount of unbreakable superhard material enters the exct mineral sizer, the mineral sizer spindle will be stuck. On this basis, we add the safety pin design to the coupling at low speed. When the spindle is stuck and the torque is too much than the designed torque, the safety pin will be stuck and the physical level will be disconnected. At the same time, the hydraulic coupler uses skid to protect the reducer and the motor from being damaged. At the same time, when the stall protection device detects that the spindle speed is lower than the set speed, it issues a stop command, and the electrical control system breaks the power supply of the main engine within the set time, so as to protect the main parts of the equipment from being damaged.
The intermediate flow link of the crushing system is reduced, which can reduce the intermediate flow link equipment of conveying belt conveyor and other materials, save a lot of energy and equipment maintenance costs for users, and reduce the environmental pollution caused by the intermediate link.
At the same time, mineral sizer can be installed at 0 elevation or steel frame, which can reduce civil infrastructure and save a lot of civil construction costs.
These are the main reasons why people in the coal crushing industry generally like to use mineral sizer. Our exct is a professional manufacturer of epc projects integrating crushing, screening and conveying solutions, with rich production experience and design capabilities, advanced processing equipment and customer performance all over the world. We look forward to working with you to create a brilliant future.
