The mineral sizer is widely used in industries such as mining, coal, metallurgy, chemical engineering, and building materials for crushing brittle materials with medium hardness or below, like limestone, coal, shale, gypsum, clay, etc. In the coal industry, it can break raw coal into appropriate particle sizes for subsequent processing. In the building materials industry, it crushes raw materials like limestone to meet the particle size requirements for the production of products such as cement and lime. It has the advantages of large crushing ratio, high efficiency, low energy consumption, uniform product particle size, less over-crushing, low noise, little dust, simple structure, and convenient operation and maintenance.
It can effectively reduce production costs and improve production efficiency. Moreover, it can achieve different graded crushing effects according to user requirements to meet diverse production requirements. It mainly consists of a machine body, tooth rollers, a transmission device, an adjustment device, etc. The machine body is usually welded with high-quality steel plates and has sufficient strength and rigidity.
The tooth roller is a key component, generally composed of a shaft, a hub, and tooth plates. The tooth plates are detachable and replaceable, which is convenient for maintenance.
The transmission device provides power for the tooth rollers, and the adjustment device can adjust the gap between the tooth rollers to adapt to different crushing particle size requirements. As an important component of the mineral sizer, the tooth plate is crucial to the crushing effect.

The following are the tips for selecting tooth plates of the mineral sizer summarized by our company during the usage process:
Material Characteristics:
Select the material and tooth shape of the tooth plate according to the hardness, humidity, viscosity, and other characteristics of the materials to be crushed. For ores with high hardness, such as quartzite, it is advisable to choose tooth plates made of wear-resistant materials like high-manganese steel. For materials with high humidity or strong viscosity, tooth plates with special surface treatments that are not easy to adhere should be selected, and the spacing between tooth shapes should be appropriately increased to prevent clogging.
Requirements for Crushing Particle Size:
If a smaller and uniform discharge particle size is required, choose tooth plates with denser tooth shapes and lower tooth heights. If the requirements for particle size are not strict, tooth plates with coarser tooth shapes and higher tooth heights can be adopted to improve the crushing efficiency and output. Working Intensity of the Equipment: For mineral sizers that operate continuously at high intensity for a long time, priority should be given to tooth plate materials with high wear resistance and high toughness, such as new alloy materials. And the thickness of the tooth plates should be appropriately increased to ensure their service life. When the working intensity is low, tooth plates with high cost performance can be selected on the premise of ensuring performance. Replacement Cost and Convenience:
Comprehensively evaluate the procurement cost, replacement frequency, and replacement difficulty of the tooth plates. Choose tooth plate products with a stable market supply and reasonable prices. Meanwhile, pay attention to their installation structures and choose tooth plates that are easy to disassemble and install to reduce the time and labor costs for equipment maintenance and improve production efficiency.
