We take a Φ900 x 900mm single rotor, irreversible multi-row hinged hammer crusher as an example to introduce its structure and parts. This type of hammer crusher is commonly seen in cement plants and is suitable for crushing limestone, coal, and other medium hardness ores. It is mainly composed of a transmission device, rotor, lining plate, grate screen, and shell.

Abstract: - Cement production is highly energy and cost intensive. The Birla cement plant requires 8760 h per year of the total operating hours to produce 1.49 Mt of clinker. In order to produce raw material preparation, clinker, preheater, rotary kiln and rotary cooler are widely used in cement plant.
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

Preheater consists of 4-6 low pressure cyclones one over the other. Number of cyclones depends on the natural humidity (moisture) in raw materials, in other words the drying capacity required to dry out raw materials in raw mill. Five stage-cyclones are commonly existing in …
preheater towers. Initially, these gas streams are combined into one. Later, these streams are split into two: one going to the mill and the other bypassing the mill. The gas stream going to the mill is mixed with ambient air for temperature control of the gases to the mill. Figure 2 shows the existing duct configuration. The red and cyan duct ...
3 In the raw mill, the material chunks are ground finer to allow high-quality blending. As the raw mill is one of the biggest energy consumers in the cement process, it is important to adjust the grinding plant in order to minimize energy losses. 4 It is essential to use a process automation system to optimize the mill process, which in turn mini-
Kiln Cooler for Cement Rotary Kiln of Dry Process Method. Cyclone Preheater Design for 5500 Ton Cement Production Line. Cyclone preheater is one of the core equipment in the new dry cement production process, which is responsible for many functions such as gas-solid dispersion, material heating, gas-solid separation, material transportation.
The cement enters each ash hopper from the small silo separated at the bottom of the machine and is filled into cement bags by high-speed impellers through each spout. The rotation speed of a roto-packer is controlled by frequency conversion, it can be adjusted within a range of 0.45 ~ 4.5 rpm to fit your production speed.
