TH Series – cascade loading spout

Product Overview

The TH Series uses a cascade cone system to guide material through multiple stages instead of allowing unrestricted free fall. By reducing acceleration and impact energy during loading, the system helps:

Reduce dust generation at the loading point

Prevent particle breakage and product degradation

Maintain consistent material gradation

Improve environmental performance with lower dust extraction demand

This makes the TH series an ideal solution for handling fragile bulk materials, abrasive materials, and applications with large vertical drop distances.

Capacity

Up to 4000t/h

Max. Length

26m

Application

Ship loading

Typical Materials

Cement, clinker, aggregates, iron ore, coal, coke, grain, fertilizer

Advantages & Features

The TH Series integrates cascade flow technology with heavy-duty mechanical design to deliver superior dust control, material protection, and operational reliability. Key engineering features are designed to support long service life, stable operation, and flexible project integration.

Heavy-Duty Hoisting System

The TH loading spout features a compact integrated hoisting system combining the winch assembly and spout body into a rigid structure. The triple-rope winch design ensures stable lifting performance while the planetary gearbox provides high torque capacity and efficient power transmission for heavy-duty applications.

Cascade Inner cone Design

The TH series uses a cascade type inner cone design to control material flow velocity and reduce material degradation and dust generation during loading. This controlled flow principle makes the TH series especially suitable for high drop height applications such as ship loading and silo loading.

Various material options including structural steel, stainless steel, and optional ceramic or UHMW liners allow the spout to be optimized for different bulk materials and wear conditions.

Dust Control System

The TH loading spout incorporates a double-layer rubber skirt to create an effective seal at the loading point, helping to minimize dust emissions during operation. Combined with the controlled flow cascade design, the system provides excellent dust control performance without requiring excessive dust extraction airflow.

Automation & Safety

The TH series includes essential safety features such as adjustable upper and lower limit switches and slack rope detection to prevent abnormal operation. Optional level detection devices are available in multiple technologies including tilt switches, rotary paddles, and vibration probes to suit different materials.

PLC control and communication interfaces allow seamless integration into plant automation systems.

Custom Engineering

Each TH loading spout can be engineered based on project-specific requirements. Configurable options include inlet configurations, wear protection systems, level detection devices, and control systems. This flexibility ensures optimal performance in demanding bulk material loading environments.

Structural Durability

Critical components such as winch shafts and drums are heat treated and precision machined to ensure smooth operation and extended wire rope life. All machined parts are zinc plated for corrosion resistance.

Industrial surface treatment including SA2.5 blasting and multi-layer coating systems provide long-term corrosion protection for outdoor and marine environments.

Optional Features

Optional configurations allow the equipment to be adapted to specific process requirements and operating conditions, improving reliability, durability and operational performance.

Pivoting Inlet Hopper

The TH series can be equipped with a pivoting inlet hopper designed for conveyors with luffing movement. The hopper consists of an upper fixed section and a lower pivoting section connected by hinge pins. This allows the loading spout to remain vertical regardless of conveyor angle, improving operational stability and reducing structural stress.

Rotary Trimming Spout

The TH series can be equipped with a rotary trimming spout consisting of a slewing bearing, drive unit, and rotating distributor head. This system enables 360° material distribution, allowing material to reach deeper and side areas of the ship hold, improving hold utilization and reducing ship loader repositioning frequency.

Frequently Asked Questions

Common questions about application range, dust control, and selection data.

Q: What is the main advantage of the TH cascade loading spout?

A: Its main advantage is the cascaded inclined conical flow-guiding structure, which reconstructs the falling path so materials are guided downward in a more controlled, low-speed state with reduced dust diffusion.

Q: What kind of materials is the TH series especially suitable for?

A: The original page specifically notes that it is particularly suitable for brittle materials such as coke and sulfur, because the structure helps reduce breakage and pulverization.

Q: What applications is the TH series suitable for?

A: The original page lists truck loading, port bulk loading, mine yard, carriage loading, and dry bulk material loading for open trucks and rail cars.
