Abstract
The present invention is composite no-lumping fertilizer and its production process. The present invention features that the fertilizer contains ammonium chloride, thiamine, potassium, monoammonium phosphate, high -concentration ordinary superphosphate and special additive, and is produced through granulating process in rotating drum at 40-60 deg.c. The said process can eliminate lumping of the composite fertilizer caused by long time storage and great height piling, and this raise the product quality, avoid the environmental pollution caused by lumping-preventing chemical additive and makes the fertilizer fast dissolve and act.
Description
Technical field
The present invention relates to a kind of composite no-lumping fertilizer, and relate to a kind of manufacture method of composite no-lumping fertilizer.
Background technology
The agglomeration problems of compound fertilizer is a puzzlement and a great difficult problem that hinders this industry development always, owing to caking is affected quality product, uses inconvenience, fertilizer efficiency to reduce, transport difficulty etc.In order to address this problem, the expert of many production of compound fertilizer producers and scientific research institution has done various explorations and research, but effect is undesirable, so they attempt to make an issue of from anti-hard caking agent, and panoramic Anti-caking Agent for Complex Fertilizer is arisen at the historic moment.Though in the production of compound fertilizer process, add the degree that suitable anti-hard caking agent has alleviated caking to a certain extent, played certain anti-caking effect, but do not tackle the problem at its root, along with the shelf-time prolongs and the highly increase of heap pressure, compound fertilizer still hardens into piece easily, and adds organic anti-hard caking agent and bring that a new problem---organic chemical industry's product is to the pollution problem of environment.
The reason of the fertile caking of compound can simplified summary be 10 words: moisture, temperature, granularity, stacking, raw material.Because the raw material that composite fertilizer uses all is some base fertilizers, itself just has moisture absorption anti-caking, and the composite fertilizer anti-caking that comes out that several raw materials mix production increases greatly, and this is the major cause of caking.Secondly, the moisture in the finished product easily forms " salt bridge " crystallization in packed stacking process, fertiliser granulates is bonded together, and causes caking.Too high as the sign indicating number bag, fertilizer under external pressure, " salt bridge " crystallization makes between particle bonding become dead closely piece.In addition, dust is many in the finished product, granularity is irregular, packaging temp is high also makes " salt bridge " easier formation.Eliminating moisture, temperature, granularity, stacking etc. causes the factor of luming not so difficult, and the elimination raw material causes the factor of luming and is not easy, the adding anti-hard caking agent only reduces or hinders the formation of " salt bridge ", make finished product loose more under external force, can not tackle the problem at its root.Therefore, must set about, solve multiple fertile agglomeration problems from crude material technology formula.
Summary of the invention
The objective of the invention is to provide a kind of composite no-lumping fertilizer and manufacture method thereof, solve owing to the fertile caking of compound is affected quality product, use inconvenience, fertilizer efficiency to reduce, transport difficulty, and owing to add anti-hard caking agent, along with the shelf-time prolongs and the highly increase of heap pressure, compound fertilizer still hardens into piece easily, and adds organic anti-hard caking agent and bring that a new problem---organic chemical industry's product is to the pollution problem of environment.
The objective of the invention is to realize in the following way: contain ammonium chloride, sulphur ammonium, potassium, monoammonium phosphate, high dense general calcium, additive in the composite no-lumping fertilizer, the material of prevented from caking or obstruction caking is arranged in pairs or groups together, by technical finesse, make it both good granulation, drying.
The method of making product of the present invention is to adopt the production of granulating method rotary drum prilling process, prilling temperature maintains 40 ℃～60 ℃, be aided with low discharge granulation water, be the linear flow shape, join when feeding intake and need evenly feed intake, fully stir, oven dry is with the big air quantity drying of high temperature, keep 40～60% returning charges ratio, finished product packing temperature≤40 ℃.
The anti-caking of some fertilizer own is strong, and the easier caking of multiple fertilizer is produced in collocation, as urea, general calcium, Qinghai potash fertilizer, ammonium nitrate, an ammonium etc.; Some fertilizer itself is difficult for moisture absorption caking, as sulphur ammonium, ammonium chloride, fused(calcium magnesium)phosphate, and two ammoniums, import potash fertilizer etc.; Some additive is easily strengthened caking, as alumina, diatomite, unselected clay; After adding, some additive can hinder the fertile caking of compound, as rare ore deposit soil, feldspar in powder, ground dolomite, sepiolite powder etc.Face shaping is good, consumption is low, can reach non-caking purpose again.
Adopt the present invention, can remove because fertile shelf-time prolongation of compound and heap are pressed and highly increase the caked problem that hardens easily, improved quality product, easy to use, fertilizer efficiency strengthens, transportation is easy, and solved in organic anti-hard caking agent organic chemical industry's product to the pollution problem of environment, instant and fertilizer is fast, be greatly favored by consumers, good market outlook are arranged.
