Installation of other parts: after the installation of the main engine and cement silo，Screw conveyor can be installed，Before hoisting，Check the filling of oil and grease at each lubrication point，An empty car running test is to be conducted，Find problems and solve them in time，Part of the dosing machine installation，Position as required by the foundation drawing，The small dosing machine can be placed on the solid foundation pier plane，Large batching machine requires pouring anchor bolts，After the installation of each mechanical part，Check that all lubrication points of various equipment are filled with lubricating oil (the lubricating oil suitable for low temperature conditions must be replaced in winter in Northeast China) or grease，Wiring and empty car running test can be conducted according to the requirements of the manual and electrical schematic diagram。3. The ground screw bolt of the cement silo is poured to the reserved pit of the foundation. When the center line of the cement silo support is adjusted to coincide with the center line of the foundation, the above four flanges are adjusted on the same level (measurement method: theodolite or transparent plastic hose with diameter of 8-10 and color water measurement method), the concrete can be selected for casting。The grade of the concrete used in the reserved pit should be one level higher than the concrete used in the foundation, and in the winter construction, in order to shorten the construction period, the concrete used should be added with early strength antifreeze。Wait for the foundation concrete to set 5-7 days before installing the cement silo body. When installing the cement silo body, it is necessary to measure the verticality of the cement silo body with a theodolite. The verticality is one thousandth of the height。In order to shorten the construction period,JS750 mixing plantproducerIn infrastructure, embedded parts can also be used to fix cement silos or mixers instead of anchor bolts。
