In-Plant Material Handling
A belt conveyor system for in-plant transport of cement materials — limestone, clinker, coal, cement, and additives. Belt widths 400-2,400mm with capacities of 30-3,000 t/h. The workhorse of cement plant material handling, connecting every production stage with reliable, continuous, high-throughput transport.
Product Overview
The cement belt conveyor is the primary in-plant material transport system in a cement plant. It moves bulk materials — limestone, clinker, coal, gypsum, additives, and finished cement — between every stage of production: from the crusher to the raw mill, from the raw mill to the silo, from the silo to the kiln, from the kiln to the cement mill, and from the mill to the packing line. Without belt conveyors, the continuous flow of material that defines modern cement production would be impossible.
In a typical cement plant, dozens of belt conveyors operate simultaneously, forming an integrated transport network. Each conveyor is sized for its specific duty — a small 500mm belt may feed additives to the raw mill at 30 t/h, while a 2,000mm belt may transport clinker from the cooler to the cement mill at 2,000 t/h. The belt conveyor's ability to handle diverse materials, capacities, and distances makes it the universal choice for in-plant material handling.
LIMING cement belt conveyors are engineered for each application with properly sized belt width, speed, drive power, idler arrangement, and take-up tension. Troughed idler sets form the belt into a U-shape to contain material, while the belt material (rubber, heat-resistant, or oil-resistant) is selected based on the transported material. Robust construction and quality components ensure reliable, low-maintenance operation in the demanding cement plant environment.
Key Benefits
Engineered for reliable continuous operation, high throughput, and low maintenance in cement plant environments.
With belt widths up to 2,400mm and speeds up to 5.0 m/s, a single conveyor can transport up to 3,000 t/h — meeting the demands of even the largest cement production lines. Troughed idlers maximize the cross-sectional material load for maximum capacity per belt width.
Belt conveyors operate continuously, 24/7, with minimal downtime. Simple mechanical design — belt, pulleys, idlers, and drive — means fewer failure points. With proper maintenance, a cement belt conveyor can operate for decades with only routine component replacement.
Electric motor drive is highly efficient — power consumption per ton is a fraction of truck or pneumatic transport. Low maintenance requirements (idler lubrication, belt tracking, occasional belt replacement) keep operating costs minimal. No fuel, tires, or operator labor required.
Belt material is selected based on the transported material: standard rubber for limestone and cement, heat-resistant (150-200°C) for hot clinker, oil-resistant for oily coal, and flame-retardant for underground applications. This ensures belt life and safety for every application.

How It Works
The cement belt conveyor operates on a simple and proven principle: a continuous belt loop moves over rotating pulleys and idler rollers, carrying bulk material on its top (carrying) surface. The belt is driven by a motorized pulley at the discharge end and returns empty on the bottom (return) side.
