通用异型铸石及特异型耐磨件
General Special-shaped Cast Stone and Special-shaped Wear-resistant Parts
风选锤式粉碎机风管,搅拌机、螺旋运输机,气力输送设备是使用通用异型铸石的设备。通用异型铸石使用效果和通用型铸石耐磨件相似,但生产相对复杂,价格也高于通用型铸石。搅拌机搅刀，挤砖机绞刀叶片，风机壳等是使用特异型铸石的设备。特殊型铸石生产更加复杂，全部都需作新模具。
The air duct, mixer, screw conveyor and pneumatic conveyor of air separation hammer mill are equipped with general special-shaped cast stone. The usage effect of general abrasive cast stone is similar to that of general abrasive cast stone, but the production is relatively complicated and the price is higher than that of general abrasive cast stone. Mixer stirring knife, cutter blade of extruder, fan shell, etc. are equipped with special stone casting. The production of special cast stones is more complicated, and all of them need to be made new moulds.
且生产量小，模具使用次数少。限制了使用厂家的应用。特异型铸石件受制造质量和安装质量的影响，使用寿命不稳定有些零件如搅刀叶片，搅拌机搅刀还要承受部分拉力，需要配制金属骨架，安装麻烦，使用性能也必然受到影响。
And the production volume is small, and the number of mould use is small. Limited the use of manufacturers. Special-shaped stone castings are affected by manufacturing quality and installation quality. Their service life is unstable. Some parts such as agitator blades, agitator blades also bear part of the pulling force. They need to prepare metal skeleton, which is difficult to install, and their service performance will inevitably be affected.
