HOW IT WORKS

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.

PRIMARY SIZERS

The feeding granularity of primary sizers is less than or equal to 1500mm and the discharging granularity is less than 300mm, or even less than 250mm.
The teeth roller of primary sizer are arranged in a special spiral shape. The teeth roller are made of wear-resistant and impact-resistant alloy steel by integral precision casting heat treatment. The hardness HRC of teeth roller is larger or equal to separately 45-55 while the impact toughness 45kg·m/cm2.
The teeth roller are heated by a solid high-frequency heating device and then installed on the shaft, which makes the match between teeth and shaft more reliable.

SECONDARY SIZERS

The feeding granularity of secondary sizer is less than or equal to 400mm (allowed feeding granularity for a small amount of 500mm), and the discharging granularity less than 100mm.
The structure of the secondary sizer teeth is toothed plate cast of Zgmn13Cr2. The tooth plate is fixed in the form of unilateral dovetail groove which is complementary to the inclined plane of the inserted clamping block, and then the tooth plate is installed on the toothed plate retaining bracket forming a surface-to-surface connection, and then is fastened and pressed by the bolt.
The material of tooth plate bracket is ZG310-570, the fixed key slot for toothed plate integrally machined by CNC（Computer Numerical Control）plano milling machine and the single side dovetail groove is machined by special angle cutter.

MINERAL SIZERS FEATURES
High Capacity and Compact：Since unique breaking action processes material quickly and efficiently, so that in high production capacities and compact layout.

Hard Rock Sizing：Sizer's unique tooth alloy formula is sufficient to handle material from soft coal (30 MPa) to hard granite (250MPa).
Accurately Control Product Size and Minimum Fines：EXCT Sizer can not only control the product size, but also minimizes dust and fine matter generation compared to other types of crushers.
Wet & Sticky Sizing：EXCT sizer can not only deal with wet sticky material, but also can deal with dry hard rock, or deal with wet sticky material and dry hard rock at the same time.
Overload Protection：EXCT sizers are equipped with overload protection, preventing the equipment from sustaining damage by unbreakable material.
Automated Operation：EXCT sizer matching PLC control system which can realize remotely automatic control and monitor to ensure continuous optimal performance.
Low Maintenance Cost：EXCT sizer adopts modular design to make wear parts reach their full service life, then greatly saves the maintenance cost and reduces downtime.
