The Secondary Sizer boasts outstanding crushing strength and processing capacity, capable of effortlessly handling various materials with compressive strength up to 200 MPa.
The crushing teeth, made of micro-alloyed high manganese steel, combined with an optimized tooth shape design, ensure the equipment maintains stable operation under heavy-load conditions.
The unique structural design enables the equipment to effectively handle wet and sticky materials, avoiding clogging. The processing capacity range is wide, covering from small and medium-scale to large-scale production lines, and it can be perfectly adapted for all, making it an ideal choice for enhancing the efficiency of crushing operations.
How Secondary Sizer Work?
Secondary Sizer crusher utilizes the shear force and tensile force between the toothed rollers to break the materials.
Secondary Sizer has two inwardly rotating toothed rollers with replaceable crushing teeth. The most suitable feeding method is by apron feeder or screening equipment, which conveys the material at a uniform rate and distributes it evenly over the toothed rollers.
1.The mineral is gripped by the leading faces of opposed rotor teeth,and to be subjected to stress under the concentrated load of the rotor teeth.The stress causes mineral to be break along its natural texture.
2.Mineral is broken in tension by being subjected to a three point loading, which between the front tooth faces on one rotor and rear tooth faces on the other rotor.
3.For the mineral that has not been fully broken, through the rotor teeth and fixed teeth of the breaker bar can be further broken to ensure the 3d dimension requirements of the discharging material.
Secondary Sizer Details
Drive Device
Two independent drive units, each drive units includes: motor, high-speed end coupling, gear box, low-speed end coupling. The high-speed end coupling uses a hydraulic coupling to connect the motor to the gearbox. The gearbox adopts parallel shaft helical gear structure to meet the requirements of power transmission, speed ratio and torque under extreme load of the Secondary Sizer .
Toothed Roller
Toothed roller can be divided into Primary Secondary Sizer Toothed Roller and Secondary Secondary Sizer Toothed Roller. Easy installation and disassembly of the Secondary Sizer tooth head, which can significantly reduce the maintenance time and lower the maintenance cost.
Housing
Secondary Sizer housing is designed as a rigid host frame, and the housing is made of cast steel and connected by high strength bolts. Wear-resistant plates are installed around the inside of the housing, and comb shaped wear plates are installed on both sides of the housing to prevent excessive material from adhering to the crusher tooth rollers.
Side Plates
The side plates of the Secondary Sizer are integrally formed through high-quality casting technology, ensuring a stable and reliable structure. After precise processing by a high-precision CNC lathe, the side plates achieve strict mating accuracy during installation. This design not only extends the service life of key components but also ensures the smooth operation of the entire machine, providing continuous support for the equipment under high-intensity working conditions.
Lubrication Device
Secondary Sizer adopts centralized automatic lubrication system, it can be more oil filling times, oil filling time Settings, reliable to ensure the effective and reliable lubrication of each part. Automatic control of oil supply interval time, oil supply pressure is large, oil supply speed is fast, the bearing is fully lubricated effectively, so that the core part of the teeth roller bearing to achieve good lubrication, greatly extend the service life of the teeth roller.
Running Gear
The tramming device is installed at the bottom of the Secondary Sizer and driven by a motor to move along a track to the maintenance access, facilitating easy maintenance and avoiding disassembly. This design allows the equipment to move smoothly between the operating and maintenance areas, reducing manual labor and minimizing downtime during maintenance, thus improving operational efficiency.
Secondary Sizers Toothed Roller
The Feeding size of Secondary sizer less than or equal to 300 mm (a small amount of 400mm is allowed), and the discharging granularity is less than 50mm. The connection form of the teeth plate adopts a single dovetail groove, which is complementary to the bevel of the insert clamping block, and then the crushing tooth plate is installed on the fixing seat of the teeth plate, formed a surface to surface connection, which is tightened and pressed by high-strength bolts. The function of the bolt becomes a fixed insert clamping block, avoiding the problem of the fixed lock bolt breaking, teeth plate falling off or difficult to disassemble and replace.
Secondary Sizer Features
01/ Compact Structure With Small Footprint
The equipment has a small overall size and is lightweight. Compared to other crushers with the same production capacity, it occupies less space, has lower requirements for the supporting structure of the factory building, and can be deployed in limited space areas, reducing the cost of factory construction and renovation, and optimizing the layout of the workshop.
02/ The Toothed Roller Material Is Wear-resistant
The crushing teeth of the primary toothed rollers are cast from wear-resistant and impact-resistant alloy steel, and the tooth plates of the secondary toothed rollers also use high-strength wear-resistant materials. They can withstand the long-term impact and friction of the materials, reducing the wear speed of the tooth parts, extending the replacement cycle of the toothed rollers, and lowering the cost of component procurement.
03/ Intelligent Control System
Equipped with a PLC intelligent control system and a large number of sensors, it enables remote monitoring of equipment, automatic operation, and overload protection. At the same time, it integrates functions such as bearing high-temperature alarm and automatic material removal, eliminating the need for on-site manual supervision, thereby enhancing operational safety and production efficiency.
04/ Low Operating Noise
The equipment adopts a low-speed crushing design, combined with an optimized vibration structure. During operation, the noise is much lower than that of traditional impact crushers. It can also be equipped with noise reduction devices to effectively reduce noise pollution, protect the hearing health of operators, and comply with environmental protection production standards.
05/ Customized Configuration
Engineers will customize configurations such as tooth shape and tooth roller size based on the material characteristics provided by the customer (such as hardness, humidity), as well as the feed and discharge particle size and processing capacity. This enables them to offer exclusive crushing solutions for different industries (such as coal, limestone, and oil shale).
06/ Less Material Loss
The low crushing rate design reduces the ineffective loss of materials during the crushing process. At the same time, the uniform output particle size significantly increases the proportion of qualified materials, avoiding waste of raw materials. The same raw materials can produce more qualified products, indirectly reducing the cost of raw material procurement.
