Ⅰ.Brief introduction
Clearance homogenizing silo is one kind of district even silos with high effects of homogenization. It is suitable for the simple compositions of raw material and raw material preparation system with low accurateness. When storied raw material reaches to an appropriate altitude, aerate and fix from adjusting valve, sampling, testing in turn, then correcting and fixing again until the compositions of raw material is qualified. Characteristics of clearance homogenizes silo are the flexible deployment and operations and good homogenizing effects. Its Homogenizing value is 1-12 and power consumption is 0.12-0.25kwh / t.

Circular Stacker Reclaimer
The circular stacker reclaimer, mainly used in raw material pre-homogenization storage yard, is ideal equipment for homogenizing such bulk raw materials as cement, coal, etc. With optimum utilization of space, this bridge type stacker reclaimer can implement continuous raw materials stacking and reclaiming under full automatic control.
How does it work?
The circular bending system is mainly characterized by Chevron stacking process and full face reclaiming process. To be specific, under the control of PLC program, the jib of the stacker will rotate back and forth in horizontal direction, and simultaneously complete amplitude and speed variable movement from rising to descending at one stroke of rotation, thereby completing continuous chevron stacking.
In addition, the end beam of the reclaimer rotates around the center column in the storage yard along a circular orbit. At the same time, the raking harrow mounted on the reclaimer moves back and forth along the bridge beam to achieve full face reclaiming. Finally, the materials will be scraped to the bottom of the center column and transported out by a belt conveyor in a pit.

Aerating Box
Aerating box is a pneumatic even device of cement industry for feeding or mixing the powder materials. It is applied to different types of raw material silo, storing silo and mixed even silo. It has mainly four categories which are rectangular shape, right angle trapezoid, isosceles trapezoid and the special form. It is characterized with simple structure, reliable performance, no noise, easy maintenance, homogeneous mixing and so on, and is widely used in the cement industry. It is the indispensable equipment for cement production and raw material storing and mixing.
Technical performance
1, mixing material : dry powder material, allowing surface water content:〈1%;
2, ventilated property:〈3 m3/m2·min;
3, wind pressure :〈4 kg/cm2;
4, ventilated layer resistance :〈1200Pa;
5, ventilated material: synthetic polyester mixed permeability layer.
Order, shape and installation:
When considering the arrangement of aerating box in the silo, in principle, the ratio of actual arrangement area among the total area should be as big as possible. This is also important for the mixing silo and the central area of mixing even silo (mixing area). Now here six basic arrangement forms with A, B, C, D, E, F are introduced for selection. A and B types arrangements (see drawing 1, drawing 2) are applied to the cement or raw materials mixing even silo under Φ12 m. Annular zone aerating silo is installed inclining to the centre; the central area aerating silo is installed with horizontal level. C type (see drawing 3) is applied to the cement or raw materials mixing even silo up with a diameter over Φ12 m. Annular zone aerating silo is installed inclining to the centre; the central area aerating silo is installed with horizontal level. D type (see drawing 4) is applied to variable kinds of cement or raw materials mixing even silo. Annular zone aerating silo is installed inclining to the centre; the central area aerating silo is installed with horizontal level, but the central area is small. E type (see drawing 5) is applied to variable kinds of cement or raw materials mixing even silo. Annular zone aerating silo is installed inclining to the centre; the central area aerating silo is installed with horizontal level.F type (see drawing 5) is applied to different kinds of cement or raw materials mixing even silo. All the aerating silos are installed with horizontal level. Each of the six basic arrangements has its own advantages, disadvantages and applying scope, so the designer and user should choose the suitable ones according to the actual situation. The need of district number of the aerating silo should be based on the actual situation, however must be consistent with requirements of four, six, eight or twelve districts.
Order Information:
the specification of the even silo, dimension factor of the aerating silo, or the draft the bottom of silo layout should be provided in order to do a tailor-made design.
