Roll crusher (roller crusher) is suitable for the fine crushing of the materials with feeding size less than 110mm, and finished particle size 3-30mm.
Roller diameter: 400-700mm
Applied materials: Limestone, slag, coke, coal, salt, chalk, gypsum, alums, brick, tile, etc.
In gerneral, there are 4 types of roll crushers including single- roll crushers, double roller crushers, triple roll and quad roll crushers. The single roller crusher machine is shorted from the twin roller crusher. After upgradation and modification, FTM company has finally created its own unique new product, that’s the powerful stone roller crusher. The equipment is designed to handle the primary, secondary and tertiary crushing stage of raw materials including coal, salt, bauxite, limestone, clay and other minerals. The roller crushing machine has many advantages, such as good product grain, less powder, cost-effective, low noise and operating costs.
At present, the domestic technology of roller crushers has mature and exquisite workmanship. It has reached an international level in all aspects and can create better market profit for Chinese roller crushers manufacturers and making famous brands in the world.
Smooth roller crusher
Applications of the powerful stone roller crushers are wide in the industrial departments such as ore dressing, chemical, cement, refractory materials, abrasives, building materials, etc. It can crush all kinds of ores and rocks with high and medium hardness, like perlite. Zhengzhou Fote machinery is the crushing manufacturer who is engaging in producing roller crushers. If the roller machine crushes perlite, it is called the perlite roller crusher, and it has more excellent effects than the common crushing equipment.
Fote roller crusher machine adopts PLC control and all these roll pulverizers are installed this system regardless it is single, double, triple or quad crushers. The control system has various functions of automatic detection, automatic switch, alarm and explosion protection, which ensures the safe operation of the equipment.
This roller crushing equipment is convenient to be installed and debugged, it also has a strong bearing capacity, large processing capacity and the reduction ratio of the breakers is large.
The stone roller crusher is equipped with a dust-proof device, which has good sealing performance, and it is very effective for preventing dust and noise pollution.
The material product processd by roller crusher machine has more uniform material, higher crushing efficiency, and longer service life.
Fixed jaw crusher is mainly used for coarse crushing and medium crushing process, comparing with roller crushers, the fixed jaw crusher belongs to fine crushing crusher. The common point of the two stone crusher equipment is that the structure is simple, and the materials of both jaw crusher machine and roller crusher equipment are crushed by extrusion principle.
The obvious advantage of jaw crusher is that the feeding port is large, the crushing ratio is large, and the output is high, while the main advantage of stone roller crushers is that it has uniform grain shape, low power consumption, low noise, and sensitive overload protection. Therefore, customers who want to buy roller crushers or stone crushers should make a reasonable consideration.
The stone roller crusher is mainly composed of the roller, roller axial bearing, pressing and adjusting device, and the driving device.
Discharging control apparatus: wedge or gasket control apparatus is installed between the two rollers.
The top end of the wedge device is equipped with an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge pushes the movable roller away from the fixed wheels. That is, the gap between the two rollers is getting larger, and the discharging granularity becomes larger. And when the wedge is downward, the movable roller is pressed by the pressing spring, on the base that, the gap between the two wheels is getting smaller, and the discharge granularity becomes smaller.
By increasing the number of the gasket, the gasket device adjusts the size of the discharging granularity. When the gasket is added, the gap between the two rollers becomes larger, and the discharging granularity is getting larger and vice versa.
Driving mechanism of roller crusher equipment: It is driven by two motors, which are brought by a triangle belt to the grooved wheel, and then rotate the stone rollers in the opposite direction. When the materials are crushed, the materials pass through the rollers from the feeding port, achieving the crushing. Finally, the finished product treated by roller crusher is discharged from the bottom of the chassis.
Transmission part of roller crusher: In order to safely install the safety cover according to the actual situation.
When the powerful roller crusher is working, firstly the two round rollers are rotated in the opposite direction, secondly, the roller crusher uses the friction of its surface to draw materials into the crushing chamber, and materials are crushed. Then, under the action of gravity, the finished product is discharged from the gap between the two rollers. Last but not least, the size of the gap determines the particle size of the finished product.
Working principle of high pressure roller crusher equipment
In the process of using the stone roller crusher, the wearing parts is a concern of the customers. The major part is the crushing roller. The ccan work stably. Due to the different materials, the crushing roller is prone to causing different degrees of wear and corrosion after working for a period of time.
In response to the above problems, the solution of Fote Heavy Machinery is to weld hard alloy on the surface of consumable parts, so that it is to achieve wear-resisting, heat-resisting, and corrosion-resistant effects. This can significantly improve the service life of the crushing rollers and save maintenance cost.
1.The shaft bears the full load of roller crusher machine, so good lubrication is important to the bearing life of machine. Good lubrication directly affect its using life and effiency. So the lubrication should be clean, and seal must be good.
2.The newly installed wheel of roll crusher is easy to loose, you have to check it regularly.
3.Pay attention to whether parts of the stone roller crusher is normal
4.Pay attention to wear parts and the replacement of worn parts.
5.Dust and other things should be removed to prevent accidents when the machine encounters unbreakable materials and the movable bearings cannot move on the chassis.
6.When the bearing oil is high, you should stop the roler cruasher working immediately to check.
7.If the rotating gear has impact sound when the machine is running, stop it immediately.
FTM Machinery is a famous roller crusher manufacturer in China and its roller crushers for sale all have high quality and perfect service life, and the price is quite reasonable. You can send us an e-mail or leave a message to get more information about the stone crushing equipment.
Display of Fote Roller Crushers
Jaw crusher is a main type of rock crusher used to crush minerals or stones into smaller sizes. It is an essential machine in a wide range of fields such as mining, quarrying and construction industries. Jaw crushers are usually used together with cone crushers, impact crushers and sand making machines to form a sandstone production line. Jaw crusher is used to crush various mineral rocks with compressive strength not exceeding 320MPa, such as cobblestone, calcite,granite, aggregate,quartz, concrete, dolomite, blue stone, iron ore, limestone, construction waste, etc.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
The circular vibrating screen is sieving equipment that can be used for classifying,dehydrating, desilting, disintegrating, and sorting. The main function of the vibrating machine is to screen and sort material through the vibration of the sieve body. The screening process is not only important to improve the value of products after but has a direct effect on the next mining operation.
Chinaware ball mill is mainly used for the mixing and grinding of materials, and the fineness of the final products is even, thus saving motive power. It can be used in both dry grinding and wet grinding.
