Details and application of mineral sizers At present, the commonly used mineral sizers module particle size has roughly the following two adjustment modes:
1) Adopt eccentric ring to adjust the roller spacing, the adjustment range is less than 40mm. Advantages:
The adjustment is simple and the workload is small. Disadvantages: the center distance and center height of crushing roller will be changed after adjustment. Therefore, the transmission part needs to be adjusted greatly. The adjustment mode is mainly used for through crusher.

2) Adopt the flat push-type regulating roller spacing, the adjusting range is less than 45mm, one crushing roller is fixed, the other crushing roller moves parallel in the sideways. The advantages are convenient adjustment and operation easily; The disadvantage is the high cost. The specific shape is shown in
Mineral sizers series is a new type of crushing equipment compared with the existing domestic toothed roll crusher, it has the significant characteristics as below:
1) The mineral sizers runs smoothly with low noise.
2) It adopt electric and torque limiting hydraulic coupling double overload protection, safe and reliable.
3) The spacing of two tooth rollers is adjusted by hydraulic means and is equipped with a stop back installation. The spacing of two tooth rollers is unchanged when working, and the discharge particle size is stable.
4) PLC is adopted to realize the program control of the crusher, it discharging and other equipment operation process, with a high degree of automation.
5) Toothed roller bearings are centrally lubricated by grease pump, which is convenient and fast.
6) The shape of the gear teeth is made of high quality wear-resistant material with long service life.
7) Toothed roller bearing adopts dust-proof double seal structure, long service life of bearing.
During operation time, the two motors transmit the power to the reducer through the torque limiting hydraulic coupling, and drive the two toothed rollers for continuous rolling movement after deceleration. The crushing material falls into the crushing chamber of the two-toothed roller from the human feed mouth of the crusher. Under the action of the teeth and the material is broken. The broken material is discharged from the discharge port. The size of the discharge particle size through the hydraulic system to adjust the two tooth roller spacing to meet the requirements.
After the technical transformation of the coal preparation plant, the output is increased to 3.5Mt/a, the crushing capacity of the original equipment is 100t/h, and the crushing capacity of the new crusher is 320t/h, which can basically meet the needs of the crushing degree of raw coal.
During the use of the old equipment, coal quality accidents due to excessive limit occurred at least 2-3 times every quarter. Similar accidents have never occurred since the use of the new mineral sizers crusher.
It is blocked 2~5 times per shift on average, the tooth plate is replaced frequently when the old equipment is used, and the maintenance is tedious and troublesome, which affects the production. The new crusher has stable performance, good sorting effect and safe and reliable operation.
