A pan conveyor chain is a specialized chain system used for transporting abrasive and heavy bulk materials, such as clinker, limestone, and raw meal in cement plants. It consists of overlapping metal pans attached to a chain, forming a continuous, sturdy surface that efficiently handles high temperatures and harsh conditions.

Fluid couplings offer smooth, wear-free power transmission by using hydraulic fluid instead of friction, making them ideal for applications needing gradual engagement and overload protection. However, they cannot fully replace mechanical clutches where positive lock-up, precise disengagement, or high torque capacity at low speeds is required.
View MoreProper maintenance and lubrication of cast pulleys are key to preventing premature wear and ensuring reliable performance. This guide explains how to clean, inspect, and apply the correct lubricants to protect against corrosion and friction, ultimately extending the service life of your equipment.
