農(nóng)藥WP、DP生產(chǎn)線工藝流程方案：

The technical process scheme ofthepesticide WP and DP production line：

粉碎操作單元是整套工藝的核心。粉碎機(jī)是確定農(nóng)藥粉碎細(xì)度工藝流程配置的關(guān)鍵，依據(jù)農(nóng)藥的特性、實(shí)驗(yàn)數(shù)據(jù)及工程應(yīng)用實(shí)例，選用氣流粉碎機(jī)或微粉碎機(jī)，其粉碎所需的進(jìn)料粒度一般為60—325目。根據(jù)產(chǎn)品特性及生產(chǎn)工藝情況，確定本工藝設(shè)計方案主要由：⑴混合、⑵粉碎、⑶混合、⑷包裝、⑸除塵系統(tǒng)。

The core of the whole process is the crushing operation unit. And the grinder is the key to determine the configuration of pesticide crushing fineness process, and according to the features of the pesticide, the experimental data and the examples of project application, select a jet mill or a microginder, whose feeding granularity required by crushing is generally 60-325 meshes. According to the product characteristics and the situation of the production technology, it is determined that the design scheme of the process is mainly composed of: (1) mixing, (2) crushing, (3) mixing, (4) packaging, and (5) the dust pelletizing system.

1、混合：將物料按所需比例分別投入混合機(jī)；混合機(jī)將物料連續(xù)混合均勻，使物料達(dá)到適合粉碎所需的物料狀態(tài)，以利粉碎（特殊物料需添加增加物料流動性的介質(zhì)）。

Mixing: put the material into the mixing machine respectively according to the required proportion; the mixing machine will mix the material uniformly and continuously to make it meet the material state that is suitable for crushing so as to facilitate the crushing (special materials needs to be added to increase the medium of the material liquidity).

2、粉碎：將來自混合機(jī)混合均勻的物料，連續(xù)輸送入粉碎機(jī)料倉，在特殊設(shè)計的螺旋元件的輸送作用下，物料進(jìn)入粉碎腔體進(jìn)行粉碎，達(dá)到粉碎細(xì)度要求物料經(jīng)分級輪分級后通過引風(fēng)至旋風(fēng)分離器氣粉分離后，關(guān)風(fēng)機(jī)出料至第二混合機(jī)。（粉碎細(xì)度：1—35微米）

 Crushing: continuously send the evenly mixed material from the mixing machine into the feed bin of the grinder, and under the transport effect of the specially designed spiral element, the material will crushed in the crushing cavity to the requirements of crushing fineness. After the material is classified by the classification wheel and made the gas-powder separation in the cyclone separator by induced air, close the draught fan and discharge the material to the second mixing machine. (Crushing fineness: 1-35 micrometers)

3、混合：將粉碎好的物料再次混合或第二次添加物料（已達(dá)到成品細(xì)度），使粉碎好的物料更均勻，符合成品要求。

 Mixing: mix the crushed material again or add the material for the second time (that has reached the finished product fineness), and make the crushed materials more even to conform to the requirements of the finished products.

4、包裝：將成品通過負(fù)壓的方式輸送至包裝機(jī)完成包裝。

 Packaging: send the finished products to a packing machine through the method of negative pressure for the completion of packaging.

5、除塵系統(tǒng)：保證在生產(chǎn)過程中粉塵的回收，達(dá)到潔凈生產(chǎn)和廢氣排放的環(huán)保要求。

 The dust pelletizing system: ensure the recovery of dust in the process of production so as to meet the environmental requirements of clean production and exhaust emission.
