Abstract

The invention relates to a method for padding a gap of a lining plate of a cone crusher, which is suitable for effectively padding and assembling the gap between a dynamic cone shell and a static cone shell of the prior cone crusher and the lining plate and aims to reduce padding cost and enhance safety. The method comprises the following steps: cleaning oil contaminations between the dynamic cone shell and a dynamic cone lining plate of the cone crusher and the static cone shell and a static cone ling plate of the cone crusher; then selecting sands with the diameters of 1-5 millimetres, and cleaning mud inside the sands by clean water; then heating the sands to the normal temperature of 10 DEG C-20 DEG C; mixing the processed sands with cement according to a weight ratio of 1.5 to 1, adding a right amount of water to the mixture to prepare cement mortar with fluidity, and padding the cement mortar with the fluidity to gaps between the dynamic cone shell and the dynamic cone lining plate of the cone crusher and between the static cone shell and the static cone ling plate of the cone crusher.

Description

technical field [0001] The invention relates to a method for filling a liner plate of a cone crusher. Background technique [0002] The cone crusher is the main equipment for crushing large-grained iron into small-sized iron ore. During the production and maintenance process, it often encounters the problem of loose and fixed cone liners, high filling costs, and difficult operation. , high risk factor and complex process. Generally, high-temperature alloy zinc is used as the pouring filler to fill the gap between the cone crusher motor and the fixed cone liner. When pouring, the alloy zinc needs to be put into the zinc pot and pass through the coke furnace. After high-temperature heating, the temperature reaches 1200 ℃ ~ 1300 ℃ , the alloy zinc can only be poured and filled after it is in a liquid state, and the pouring time is 12 to 13 hours. Slowly pour the liquid alloy zinc into the special spoon, and then slowly pour it into the pouring hole, allowing the liquid alloy ...
