[0014] In the utility model, the first regulating valve, the second regulating valve, the first valve and the second valve can all adopt electric control valve. In the utility model, when the discharging of the batching and stirring tank is higher than the feeding of the sand mill, the first branch can not be provided with liquid pump, and preferably, the liquid pump is installed on the first branch. In the application, the sand mill and the batching and stirring tank are all existing equipment.
[0015] A kind of methonium compound product production system, including ingredient stirring tank 1, sand mill 2, the sand mill uses zirconium bead as grinding medium, also including circulating tank 3, the circulating tank volume is less than ingredient stirring tank, the feed pipe of sand mill is connected with two branches, two branches are first branch and second branch respectively, first branch is equipped with first regulating valve 4, first branch is connected to the discharge of the bottom of ingredient stirring tank 2, first branch is equipped with first liquid pump 9, second branch is equipped with second regulating valve 5, second branch is connected to the discharge of the bottom of circulating tank 3, when first regulating valve opens, second regulating valve closes, when second regulating valve opens, first regulating valve closes, liquid level meter is installed on circulating tank, in the embodiment, liquid pump 10 is installed on second branch, liquid pump can form pressure, it is favorable to eliminate dead angle in sand mill, by liquid level meter, in and out balance can be controlled in circulation, the discharge pipe of sand mill 2 is connected with two pipelines, first pipeline and second pipeline, first pipeline is connected to system discharge by first valve 6, second pipeline is sequentially linked to the inlet of upper circulating pipe by second valve 7 and circulating pump 8, first valve and second valve are interlocked, the inlet of upper circulating tank is horizontal direction, so as to reduce the interference of feed to liquid in circulating tank, first pipeline and second pipeline are located at the same horizontal height, so that there is no dead angle material in the discharge pipe of discharge.
[0016] The working process of the system is as follows: first, in the first step, the material is mixed and added to the ingredient stirring tank, water is added and stirred for about one hour, the volume of the ingredients in the stirring tank is greater than the designed working capacity of the sand mill, after stirring is completed, the liquid mixed with raw materials is introduced into the sand mill through the first branch, the volume of the introduced liquid is adapted to the designed working capacity of the sand mill, and the remaining ingredients are temporarily stored in the ingredient stirring tank, the sand mill is started to work for a period of time (for example, 30 minutes), then the circulating pump on the second pipeline is started to input the material in the sand mill into the circulating pipe, and the remaining ingredients in the ingredient stirring tank are input into the sand mill, the sand mill is started to grind for a period of time (for example, 20-25 minutes), then the second valve, the circulating pump and the first regulating valve are opened, so that the material circulates between the sand mill, the circulating tank and the sand mill, the liquid level of the circulating tank remains basically unchanged during the circulation, the next batch of ingredients can be prepared in the ingredient stirring tank during the circulation, the amount of circulating material is about 3-4 times of the total amount of ingredients, and the circulation time is about 3 hours, then the second valve and the circulating pump are closed, the first valve is opened, and the sand mill is worked while discharging, and a batch of production is completed after discharging is completed.
[0017] In the system, the feed of the circulating tank is in the upper part, the fine particles in the material of the circulating tank form a suspension in the liquid, and the larger particles tend to move to the lower part of the circulating tank, so the particle size of the particles in the lower part of the circulating tank is to be hit, and since the discharge of the circulating tank is at the bottom, the larger particles of the solid material can be selectively made to enter the sand mill to a certain extent through the circulating tank, thereby improving the grinding specificity. The grinding efficiency is improved, and the dead angle in the sand mill can be destroyed in the circulation to achieve good results. In the production system, the volume of material that can be produced per batch is the design working capacity of the sand mill + the volume of the material in the circulating tank, and the production capacity per batch is significantly improved compared with the traditional production method. When the production system is produced, because the ingredients can be prepared in the batching and stirring tank while circulating, the production time of each batch is the time of circulating and discharging except for the first batch, and the production time of each batch can be reduced by about one hour compared with the traditional production equipment.
