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. 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. 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.

The crushing method of EXCT sizer is both compact and efficient. The operating principle of the sizer crusher is to generate continuous pressure between the tooth rollers through the reverse rotation of the two tooth rollers to continuously crush the material.
Based on our deep study of the processing material features, and drawn from the advantages of other brand Sizers, EXCT has produced a high efficiency, low maintenance cost crusher, the EXCT sizer. Its actual use effect is exactly equal to the crushers of
 other well-known brands.

Optimum Performance Increased Safety Easy Maintenance Cost Saving
1. Sizer's unique tooth alloy formula is sufficient to handle material from soft coal (30 MPa) to hard granite (250MPa). 1. Sizers include overload protection device, preventing the equipment from sustaining damage by unbreakable material. 1. The wearing parts of sizers adopt modular design, and makes it easy to replace quickly and reduces downtime. 1. The modular design of wear parts makes all wear parts reach their full service life and greatly saves the maintenance cost.
2. The handling capacity of primary sizer can be reached 10,000 t/h, and the secondary sizer range covers up to 4,000 t/h. 2. Sizer matching PLC control system can realize automatic control start and close, overload protection and other functions. 2. Integrated moving unit allows the sizer to be moved into maintenance position quickly for easy maintenance and reduced downtime. 2. The compact structure design of sizers can reduce the cost of steel structure and civil engineering.

Application Industry and Materials for EXCT Sizers

EXCT sizer crushers are available in a variety of models and provide primary and secondary crushing operations for a wide range of materials such as coal, lignite, limestone, clay, shale, etc.
For example, EXCT's coal sizer crusher is a self-developed energy-saving crusher, which is environmentally friendly and efficient. It is especially aimed at the coarse and intermediate crushing of the brittleness bulk material, and the brittleness material with a strength below 250MPa.After iron and impurity removal, raw coal can be broken directly without gangue picking, which can simplify the coal crushing process and reduce the construction investment and production costs of coal preparation plants and power plants. This type of crusher has the advantages of large capacity, low energy consumption, long life of its wearing parts, and so on, especially suitable for coal, mining, metallurgy, chemical industry, and other industries.
