Afghanistan has abundant mineral resources and a steadily developing agricultural sector. As the demand for high-quality animal products grows, local feed manufacturers are looking for economical and reliable ways to produce nutritional additives. One promising opportunity is the production of granite-based animal feed additives, such as poultry grit and mineral stone meal, from local stone resources. To achieve a stable output of 5-10 t/h, the grinding system must be robust, efficient, and easy to operate. This article discusses how a professional granite grinding mill from Shanghai Zenith Machinery Co., Ltd. can help animal feed producers in Afghanistan turn raw granite into a valuable feed additive.
Granite powder, often referred to as stone meal or mineral grit, has practical applications in the animal feed industry. When processed to a controlled particle size, it serves as a source of natural minerals and helps improve feed efficiency. In poultry nutrition, granite grit is especially valuable because it supports the grinding action of the gizzard, allowing birds to break down fibrous feed materials more effectively. For cattle, sheep, and goats, a fine granite-derived mineral supplement can supply essential minerals that support growth, bone development, and milk production.
Afghanistan has large deposits of granite, and using locally processed granite reduces the need for imported feed additives. This lowers cost and creates local employment. However, the production of granite-based additives requires careful grinding. The material is hard and abrasive, so the mill must be engineered with wear-resistant parts and stable operation in mind. A well-selected grinding mill can consistently produce the desired particle size while minimizing downtime and maintenance expenses.
Choosing the right granite grinding mill for animal feed additive production is not only about capacity. The following factors must be considered:
Shanghai Zenith Machinery Co., Ltd. understands these requirements. We specialize in the research, development, and production of industrial powder grinding equipment. Our product range includes MTW Trapezium Grinding Mill, MTM Medium-Speed Grinding Mill, Raymond Mill, LM Vertical Grinding Mill, LUM Ultrafine Vertical Mill, XZM Ultrafine Grinding Mill, and Hammer Mill. For this application, the MTW Trapezium Grinding Mill is particularly well suited to the needs of Afghan feed producers.
The MTW Trapezium Grinding Mill has multiple international patents and is known for its excellent performance in hard mineral grinding applications. Its compact structure, long service life, and eco-friendly design make it a reliable choice for granite grinding. The mill uses a trapezium-shaped grinding ring and heavy-duty rollers to crush and grind materials efficiently. The air classifier ensures that particles of the desired size are collected while oversized material is returned for further grinding.
For the specific requirement of 5-10 tph, we recommend two models from the MTW series: the MTW110Z and the MTW138Z. The MTW110Z is a compact solution that can produce around 3-10 tons per hour, making it suitable for medium-scale feed additive production. The MTW138Z offers a higher capacity range of 6-17 tons per hour, giving operators a comfortable margin even when grinding hard granite or producing fine powder. Both models can be configured with auxiliary equipment such as a jaw crusher, bucket elevator, vibrating feeder, dust collector, and packing machine to form a complete production line.
The following table lists the key technical parameters of the recommended Zenith MTW grinding mills. These specifications are based on our company’s product data and provide a clear reference for project planning.
| Model | Max Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110Z | <30 | 1.6-0.045 | 3-10 | 55 | 55 |
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 | 110 |
The final product size can be adjusted through the classifier and mill settings. For poultry grit, a coarser setting around 0.5-1.5 mm is often preferred. For a mineral feed powder, the mill can produce particles down to 0.045 mm. This flexibility makes the MTW series suitable for a wide range of animal feed applications in Afghanistan.
To establish a 5-10 tph granite grinding plant, several steps are required. The process starts with conventional crushing: raw granite blocks are reduced by a jaw crusher or hammer mill to a size below 30-35 mm. The crushed material is then conveyed to the MTW grinding mill feed bin. A vibrating feeder controls the feed rate, ensuring stable operation and consistent product quality.
Inside the mill, the granite is ground between the grinding roller and the grinding ring. A high-pressure blower creates an airflow that carries the fine particles upward to the classifier. The classifier separates material according to the target fineness; acceptable particles pass through and enter the cyclone collector or bag filter, while coarse particles drop back onto the grinding table for further size reduction. The final powder or grit is collected and sent to a storage silo or packing machine.
For animal feed additive production, the plant can also include metal detection and sieving equipment to ensure purity. This is important because feed additives must be free of oversized granules, metal contaminants, and other impurities. Zenith’s complete system can be customized to meet these requirements, providing a safe and hygienic production environment.
Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China, with extensive experience in the field of ultra-fine powder grinding and general industrial milling. Our engineers have helped customers around the world design efficient grinding plants for minerals such as limestone, granite, basalt, and feldspar. We understand the local conditions in developing markets, including Afghanistan, and we provide robust solutions that are easy to install, operate, and maintain.
Our MTW Trapezium Grinding Mill is designed with a focus on energy conservation, high efficiency, and environmental protection. It consumes less energy per ton of product than traditional mills, and its advanced sealing system reduces dust leakage. The mill is also equipped with an intelligent control system that simplifies operation for local staff. Spare parts are designed for long service life, reducing the frequency of maintenance and the overall operating cost.
By investing in a local granite grinding mill, Afghan feed manufacturers can reduce dependence on imported mineral additives. The production of granite grit and stone meal from domestic resources creates value within the local economy. It also supports the growing poultry and livestock industries that need reliable feed ingredients. With the correct equipment selection, the plant can produce 5-10 tons of finished feed additive per hour, which is enough to supply a considerable number of feed mills and farms.
The operation also creates jobs at various stages, including crushing, grinding, packing, loading, quality control, and maintenance. For investors, the payback period is attractive because the raw material is abundant and the production cost is low. The final product can be sold to feed manufacturers, agricultural cooperatives, and livestock farms throughout Afghanistan and neighboring countries.
The demand for animal feed in Afghanistan is increasing, and so is the need for economical mineral feed additives. Granite is a locally available material that can be transformed into a useful feed additive with the proper grinding technology. The MTW Trapezium Grinding Mill from Shanghai Zenith Machinery Co., Ltd. offers a reliable and efficient solution for this application. Whether the producer chooses the MTW110Z for 3-10 tph operation or the MTW138Z for a larger safety margin and future expansion, Zenith can provide complete engineering support, equipment supply, and after-sales service.
For any feed additive project in Afghanistan with a target capacity of 5-10 tph, the MTW series is an excellent choice.
