For the preheater, there are mainly two types, cyclone preheater, Vertical Preheater, the previous preheater is mainly used for cement clinker production process and the later is mainly used for quicklime production process, it`s used for heat exchange between the materials and the waste gas from the Rotary Kiln or Vertical Shaft Kiln, After absorbing the heat from the kiln gas, usually the temperature of the material can be 700-900 ℃, and some can be decomposed before entering the rotary kiln, the capacity can be increased about 30% with the preheater, and heat efficiency can be increased 40%.

Wuhan Shipbuilding 400,000 tons ore ship supporting anchor winch successfully passed ship inspection and inspection
It is reported that the anchoring machine for Wuhan Shipyard's 400,000-ton ore sand ship has successfully passed the ship inspection and inspection of DNV GL and China Classification Society (CCS). The anchoring machine includes two K122U3 windlass and ten 315KN systems. Mooring winch.
On the basis of optimizing the cost of 319,000 tons of VLCC anchor winch, Wuhan Shipbuilding continued to carry out “design optimization, weight reduction and cost reduction†as the main content of the 400,000-ton series marine anchor winch in accordance with the first-class requirements of the international standard. Improve quality and efficiency.
From the aspects of structural design and material selection, the structure optimization of the anchoring machine is comprehensively carried out, and the product structure is optimized to achieve the optimal product structure; the work of “weight reduction and cost reduction†is carried out in terms of equipment weight and layout size, and passed in the design process. Three-dimensional design, simulation and other means to analyze the working conditions of the anchoring machine, gear life and contact frequency on different shafts, drum cylinder load and loading mode, spindle load and force fulcrum, etc., continuously optimize the wall thickness of the cylinder, Gear width and thickness dimensions, spindle material, base, single bracket, anchor sprocket material thickness, brake hinge arrangement and material of the parts.
At the same time, combined with the refinement requirements of the process, refine the processing steps, accurately calculate the processing time of each process, optimize the machining process to reduce the blank amount of parts, and carry out centralized procurement of similar parts, effectively reducing the procurement cost of parts and ensuring optimal product structure. The weight is reduced by 10%, and the goal of “weight reduction and cost reduction†of the anchoring machine is realized.
