Bentonite, a clay mineral primarily composed of montmorillonite, has long been valued for its remarkable absorption, cation exchange, and binding properties. In Nigeria, the application of bentonite in animal feed additive production has drawn significant attention in recent years, particularly as the livestock industry expands to meet rising protein demands. To achieve optimal performance in formulations, bentonite used in animal feed must be finely ground, generally around 80 mesh. This level of fineness improves the distribution and reactivity of the bentonite within the feed composition, enhancing its binding ability and nutritional performance. Using state-of-the-art grinding systems ensures a consistent particle size, improved quality, and higher production efficiency.
Shanghai Zenith Machinery Co., Ltd., a distinguished manufacturer of industrial grinding equipment in China, offers advanced grinding solutions ideally suited for bentonite processing applications in the animal feed industry. The company has achieved remarkable success in ultra-fine powder grinding, offering a wide array of precision-engineered equipment for varied mineral applications. The following discussion highlights the industrial importance of bentonite in feed additives, grinding process requirements, and the application of Zenith’s top-tier mills, notably the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill, for producing 80-mesh bentonite powders in Nigeria.
Bentonite serves several purposes as an animal feed additive. Its superior absorption capacity enables it to bind toxins and improve pellet quality. When incorporated into livestock feed, it assists in the reduction of harmful substances such as mycotoxins, improves nutrient absorption, and enhances pellet durability. These qualities lead to better animal health, improved feed efficiency, and lower feed production costs.
In Nigeria, demand for high-quality animal feed continues to grow along with rapid population and livestock expansion. The Nigerian feed manufacturing sector faces challenges in achieving consistent feed texture, nutrient retention, and additive performance. Using finely ground bentonite in the formulation helps overcome these challenges. The necessary 80 mesh particle size ensures uniform dispersion and effective toxin absorption within feed production lines.
Producing bentonite at 80 mesh requires a highly efficient grinding process capable of consistent particle control without excessive energy consumption. The equipment must ensure uniform size reduction, low residue content, and minimal contamination. Key performance factors in an ideal grinding system include:
To meet these requirements, Shanghai Zenith’s MTW Trapezium Grinding Mill and LM Vertical Grinding Mill stand out as robust solutions that deliver industrial-grade performance, reliability, and energy efficiency. These mills are designed for high throughput and stable particle size distribution, making them ideal for the Nigerian feed processing sector.
The MTW Trapezium Grinding Mill is recognized for its innovative design and precision control in mineral grinding. Engineered for intermediate and fine grinding stages, it ensures consistent production of particles between 1.6mm and 0.045mm, making it ideal for preparing bentonite at 80 mesh.
Equipped with advanced bevel gear transmission and thin oil lubrication, the MTW series provides superior reliability and energy savings. The airflow recycling design ensures minimal dust emissions, supporting environmentally friendly production in compliance with Nigeria’s environmental standards.
| Model | Max. Feed Size (mm) | Final size (mm) | Capacity (t/h) | Main motor (kW) | Fan motor (kW) |
|---|---|---|---|---|---|
| MTW110 | <30 | 1.6-0.045 | 3-9 | 55 | 55 |
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 | 110 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 | 200 |
For bentonite feed additive production at 80 mesh, models MTW138Z and MTW175G are strongly recommended. They provide the precision and robustness required in grinding bentonite with consistent output across varying feed compositions. Their efficient classification system ensures stable results even in high-humidity Nigerian environments.
The LM Vertical Grinding Mill further advances grinding performance through integration of multiple functions — crushing, drying, grinding, and classifying — into a single compact unit. It enables operators to process bentonite directly without the need for separate pre-crushing equipment, thus decreasing overall production cost and energy expenditure.
One of the standout features of LM series mills is their capability to handle materials with varying moisture content. Bentonite typically exhibits moisture levels of 10%-15%, making it essential for a mill to integrate efficient drying mechanisms. The LM mill’s hot air system and adjustable airflow deliver this capability seamlessly. Operators benefit from steady output and precise fineness adjustment between 170µm and 40µm, enabling smooth production of high-quality bentonite powder for feed use.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 | <38 | 200 |
| LM190K | 1900 | 23-68 | 170-40 | <45 | 500 |
| LM280K | 2800 | 50-170 | 170-45 | <50 | 1250 |
When used for bentonite feed additive processing, the LM130K model offers a balance of compact size and sufficient throughput, ideally suited for small and medium feed mills in Nigeria. Meanwhile, larger industrial plants may choose the LM190K for higher output and integrated batch automation.
To ensure efficient production and consistent output quality, several operational settings and maintenance strategies are essential for bentonite grinding and feed additive formulation in Nigeria:
The growing feed industry in Nigeria presents lucrative opportunities for bentonite producers and grinding equipment suppliers. With rising pressure on feed producers to achieve international quality standards, the use of finely processed additives like bentonite will continue to gain traction. Grinding mills that maintain high uptime, consistent product quality, and minimal energy consumption contribute directly to industry competitiveness and sustainability.
