Abstract

The invention discloses a method for assembling a barrel body and a grinding roller of a horizontal roller mill. The method comprises the following steps of: (a) assembling an auxiliary platform; (b) hoisting a sliding trolley which is assembled onto a main rail; (c) hoisting the barrel body onto the sliding trolley; (d) hauling the sliding trolley by using traction equipment to move from one side of the main rail to a pedestal of equipment until the sliding trolley arrives above the pedestal of the equipment; (e) fixing the sliding trolley and supporting transverse beams of the sliding trolley respectively by using fixed supports; (f) disassembling steel beams on left side and right side, descending the fixed supports and descending the sliding trolley and the barrel body to the pedestal of the equipment; (g) disassembling the sliding trolley; (h) assembling a maintenance trolley on an auxiliary rail; and (i) hoisting the grinding roller onto the maintenance trolley, hauling the maintenance trolley to move from one side of the auxiliary rail to the pedestal of the equipment until the maintenance trolley and the grinding roller enter the barrel body, and connecting the grinding roller. By adoption of the method, assembly errors can be reduced and stability of the platform is guaranteed.

Description

technical field [0001] The invention relates to a cylinder body and a grinding roller installation method, and in particular, the invention relates to a horizontal roller mill cylinder body and a grinding roller installation method. Background technique [0002] The world's first horizontal roller mill that entered industrial application was developed by the French machinery and equipment group (FCB), called HOROMILL. Wear, low failure rate and other advantages have attracted much attention. At present, nearly 20 cement companies in more than ten countries around the world are using horizontal roller mills, and two cement companies in my country have used this equipment. The first horizontal roller mill was built in Mudanjiang in 2003. Put into operation. In recent years, starting from the needs of the domestic market, my country has developed a series of horizontal roller mills with independent intellectual property rights. [0003] With the successful application of hori...
