For limestone mining company, calcium magnesium soil conditioner granulation solution offered a practical route for turning limestone from into a saleable agricultural input. This is a feedback we receive on August 10th, 2026 from Zimbabwe quarry owner, Kudzai Mugwira. He required a 10 TPH solution to process limestone + dolomite+ bentonite into quality calcium magnesium soil conditioner granules. balanced nutrients, 3-6mm adjustable and mechanical spread applicable. So, there is a YUSHUNXIN rotary drum granulation solution for you. This requires a cost and area of only USD 220,000 and 1500㎡. The following are the specific details of the negotiation in this case:

Can the system produce required granular limestone soil amendment?
For limestone quarry owners and mineral powder processors, the key challenge is not only converting lime powder into granules, but also with required quality for commercial soil amendment markets. Here, with the calcium magnesium soil conditioner granulation solution, you can get
Target granular soil conditioner production
To produce quality calcium magnesium soil amendment with required elements of Ca and Mg, it is necessary to feed limestone, dolomite and bentonite precisely and mix them evenly. This better creates stable material conditions for the following granular soil conditioner production process.
Here, the dynamic batching machine accurately controls the raw material feed proportions because of sensitive weighing system. While the double-shaft mixer ensures uniform distribution before granulation. Due to the two opposing stirring shafts move simultaneously.

3-6mm round soil conditioner granules making
In addition, you can extend the soil amendment production business to mechanical farming investors by the rotary drum granulation solution.
Because, with wet granulation process and natural rotation pelletizing, you can process lime or limestone powder into round ball granules. Which has better mobility for mechanical spreading. Moreover, you can regulate particle size of the calcium magnesium soil conditioner freely between 3mm and 6mm.

90%-93% limestone powder to granules
In general, for the 10TPH calcium magnesium soil conditioner granulation, the conversioin rate is 90%. But with a disc pelletizing machine equipped after, you can improve it to 95%. Namely, with 10 tons of mixed limestone, dolomite and bentonite, you can get a granules output of 9.3 tons.
Further, to separate the uniform limestone soil amendment granules, it is advisable to use a rotary screen after granulators. How to dispose of the sieved pellets residues? This the reason why we equip the screener with a chain crusher. It will grind the returned granules into powder and send to granules formation again. Material loss reduction and resource utilization improvement.

Dust reduction better
Then, for calcium magnesium soil conditioner granules manufacturing, as a Zimbabwe investor, you may also focus on the dust reduction. For this, YUSHUNXIN will offer you considerate designs.
1. Dust collecting systems for drying, cooling and crushing
To effectively reduce the dust emission, we adopts dual collection processes. Not only cyclone dust removers but also water curtain collectors. Finally, to 13–18 mg/Nm³.
This dust reduction systems are equipped for both limestone powder grinding step and soil amendment pellets drying and cooling stages. Where requires dust collection the most.
2. closed sieving machine add
Moreover, for screener of limestone-based soil amendment granules, it is advisable to use a closed one.
3. dust covers on conveyors
According to your needs, we also can offer you belt conveyors with dust covers. This can help you control powder emissions in the whole process, from material feeding to packaging.

What does the calcium magnesium soil amendment making system require?
To support the calcium magnesium soil amendment granules production line work well, it is advisable to prepare a budget of 220,000 USD, workshop of 4000㎡ area, 50-100 mesh fineness materials and clear the local energy conditions of power supply and fuel.
220,000 USD budget
For this Zimbabwe limstone-based soil conditioner granulation project, the equipment investment was approximately USD 220,000.
The equipment package covered not only the all sets equipment of mineral rock crushing, batching, mixing, granulation, drying, cooling, screen, packaging, dust collection, conveyors, but also auxiliary machines and accessories of PLC control, drying heat generation, support frames, support rollers, screen mesh, spare parts, etc.

4000㎡ workshop
For a commercial limestone soil conditioner manufacturing project, workshop planning affects equipment arrangement, material transfer, and future operation. For this 10TPH project, the required workshop area was around 4,000㎡. The layout considered:
- Raw limestone and dolomite storage – 1,000-1,200㎡
- limestone crushing area – 400-500 ㎡
- powder granulation section- 1400-1500 ㎡
- Finished product storage area-800-900㎡

If you send us your workshop area for the calcium magnesium Soil conditioner granulation line first. we will offer your customized layout for you.
fine material powder preparation
Before entering the granulation process, limestone and dolomite materials need suitable preparation. Especially the mineral fines crushing.
Because only the limestone and dolomite powder in around 50-100 mesh fineness, you can produce soil amendment granules of 3-6mm better.
If your raw limestone arrives as large rocks of 300-1000mm, additional Jaw crusher equipment may be required. Adversely, for <30mm limestone processing, using a Raymand mill is enough.

Energy conditions
Before equipment manufacturing for your calcium magnesium soil conditioner granulation plant, local energy conditions should be confirmed.
For Zimbabwe, it is advisable to maintain voltage of 380V/400V and frequency of 50Hz. If you requires others, please tell us first, YUSHUNXN will design it according to your requirements.
As for the drying section, natural gas is a standard heating option. However, fuel oil or biomass pellets can also be considered according to local availability.
