One Conveyor Range, Four Duties

The Goldilocks conveyor line covers four ways grain moves inside a plant: the trolley belt, the fixed belt, the enclosed scraper and the screw. Each series is sized from the lightest dust point to the heaviest production flow, with published capacities, belt widths and scraper sizes in one catalog. A mill starts with one TDSP belt, adds a TGSS scraper where dust control matters, and finishes the powder line with a TLSS screw. The same factory builds the blowers and collectors, so the whole conveying side stays on one standard. Every machine is test-run before export packing, shipped with matching manuals, and backed by direct factory support. From loading the truck to feeding the mill, one catalog moves the grain. The factory quotes the conveyor, the blower and the airlock from one list, and the order ships under one export routine. That is the whole point. Good. Done.

Sealed Conveying, Steady Flow

Dust is the quiet enemy of a grain plant, and the Goldilocks conveyor line is built to keep it inside. The TGSS scraper runs in a closed trough, and the TLSS screw runs in a sealed casing, so powdered grain and fine particles move from point to point without spilling. The TDSP belt does the open moving jobs, while the scraper and screw take the dusty and steep ones. Capacities run from 15 to 80 tonnes per hour across the range, with published numbers for every model. The factory in Hunan test-runs each conveyor before packing it for sea freight, and the manuals match the model on the plate. For a plant that wants a clean floor and a steady feed, one catalog covers the whole dust side. The factory test-runs each machine before packing and answers after delivery, so the dusty line stays clean and quiet. That is the difference.

Multi-Point Loading and Unloading

A plant seldom needs a conveyor that feeds from one point and ends at one point, and the Goldilocks line is built for the real layout. The TDSP trolley belt moves under the bin and unloads at several points along the run, which saves a row of short conveyors. The fixed TDSP belt takes feed hoppers at multiple positions, and the TGSS scraper accepts material in and out at several points along the trough. This flexibility cuts the number of machines on the floor and keeps the layout clean. Every model sizes from the same catalog, with capacities from 15 to 80 tonnes per hour. One conveyor does the job of two, and the plant pays for one. The catalog lists the capacity, the belt width and the drive rating next to every model, so the layout is decided on paper. The factory confirms the choice in writing. Simple. Good. The layout pays off.

Products Introduction

TDSP Series Belt Conveyor
The TDSP Series Belt Conveyor handles horizontal and inclined feeding of granular and powdered materials across grain, food, feed and mining plants. The modular middle sections ship flat and bolt together on site to cut freight cost, and feed hoppers can be fitted at multiple positions for multi-point loading. The four models TDSP40, TDSP50, TDSP60 and TDSP80 cover capacities from 25 to 80 tonnes per hour with belt widths from 400 to 800 millimeters. Simple and easy to maintain, it ships test-run with documentation matching the model as the workhorse of the open conveying run.
TDSP Series Grain Discharge Trolley Belt Conveyor
The TDSP Grain Discharge Trolley Belt Conveyor handles horizontal and inclined feeding of granular and powdered materials for grain, food, feed and mining plants. The mobile trolley moves along the silo or bin row and unloads at several points, so one long belt serves several bins without a row of short machines. Capacities run from 25 to 80 tonnes per hour, belt widths from 400 to 800 millimeters, and power from 2.2 to 15 kilowatts. Test-run before shipping with a matching manual and parts list, it is the layout choice that saves machines in a silo block.
TGSS Series Enclosed Screw Conveyor
The TGSS Enclosed Scraper Conveyor handles horizontal or inclined upward conveying of powdered, coarse or fine materials, with multi-point feeding and discharge, robust construction, stable running and low maintenance. Material is pushed through the closed trough by the scraper chain, so dust stays inside and the floor stays clean. The four models TGSS25, TGSS32, TGSS40 and TGSS50 cover capacities from 15 to 80 tonnes per hour, with scraper sizes from BF240x50 to BF480x70 and power from 2.2 to 15 kilowatts. Test-run before shipping with matching documentation, it is the workhorse of the dusty enclosed run.
TLSS Series Spiral Conveyor
The TLSS Screw Conveyor conveys powdered, granular and small-block materials such as fly ash, cement, sand, lump coal and grains across many industries. It has a simple structure and easy maintenance, a compact cross section, material inlet and outlet at any point along the length, and a tightly closed casing for good sealing. The six models from TLSS160 to TLSS400 cover outer spiral diameters from 160 to 400 millimeters with pitches from 120 to 400 millimeters. Blades and bearings are listed by model, and it ships test-run with matching documentation as the workhorse of sealed powder and by-product conveying.

How to Size a TDSP Belt Conveyor

Sizing a belt conveyor starts with the capacity, not the price. The Goldilocks TDSP series covers four belt widths: 400, 500, 600 and 800 millimeters, with published capacities from 25 to 80 tonnes per hour. Start from the tonnage the line must carry, pick the width that matches it, and then check the drive power, which runs from 2.2 to 15 kilowatts. The middle sections are modular, so the plant bolts the length on site and pays only for the freight of flat sections. The trolley version unloads at several points under the bins, while the fixed version accepts feed hoppers at multiple positions. Every number is in the catalog, so the choice is made on paper before the crane arrives. The factory confirms the model against the actual duty in writing.

Why Grain Plants Choose the TGSS Scraper

A belt conveyor spills dust wherever the grain tumbles, and a grain plant that runs a dusty line pays for it every shift. The TGSS scraper runs in a closed trough, so the material stays inside and the floor stays clean. It handles horizontal and inclined upward runs, accepts feed and discharge at several points along the trough, and comes in four sizes from the TGSS25 at 15-20 tonnes per hour to the TGSS50 at 60-80. The scrapers are listed by size, from BF240x50 to BF480x70, so a worn part is ordered by number. The chain tension is adjusted from outside, and the casing is built for abrasive grain. The factory test-runs each machine before export packing, with a matching English manual. For a plant that has measured its dust bill, the scraper pays for itself. It handles horizontal and inclined upward runs, accepts feed and discharge at several points along the trough, and comes in four sizes.

The factory test-runs each machine before export packing, with a matching English manual.

Sealed Powder Conveying with the TLSS Screw

Powder does not like open belts, and the Goldilocks TLSS screw conveyor is built exactly for that. The material moves inside a sealed trough, so flour, bran, husk and fine grain stay in the machine and off the floor. Six sizes run from the TLSS160 to the TLSS400, with outer diameters from 160 to 400 millimeters and published pitches for each. The casing can be closed tightly for dust control, and material can enter and leave at any point along the length. The simple structure keeps maintenance to greasing the bearings and replacing the blade when it wears, all listed in the manual by model.

Unload at Every Bin with the TDSP Trolley

A row of short conveyors under a row of bins costs money, space and belts, and the trolley belt cuts the row in one machine. The Goldilocks TDSP trolley belt carries grain along the row and unloads at the points the operator drives it to, so one long belt serves several silos or bins. The trolley moves along the run, stops where the bin needs it, and discharges. Capacities run from 25 to 80 tonnes per hour with belt widths from 400 to 800 millimeters, and the power rating stays in the 2.2 to 15 kilowatt range. The middle sections bolt together on site, and the plant adds hoppers where it needs feed. Every model sizes from the same catalog, and the factory confirms the choice in writing. For a new silo block, the trolley belt is the layout that saves machines. The trolley moves along the run, stops where the bin needs it, and discharges.

Match the Conveyor to the Air System

A conveyor does not work alone. It feeds a mill, receives from a silo, or drops into an airlock, and if the rate does not match the next machine, the line stalls. The Goldilocks factory builds both sides, so a plant sizes the TDSP belt, the TGSS scraper or the TLSS screw against the blower and the airlock on the same page. The published capacities make the match on paper: choose the conveyor, pick the airlock pocket that meets it, and the blower rating falls out from the same catalog. The whole line ships under one export routine, with one invoice, one parts list and one support team. The factory test-runs every machine before packing, and the manuals match the model plates. For a plant that plans a new floor, one catalog ends the cross-supplier guessing.

More Features for Product

Dust is the quiet cost of a grain plant, and the Goldilocks line is built around keeping it off the floor. The TGSS scraper runs in a closed trough, the TLSS screw runs in a sealed casing, and both keep powdered grain inside while the belt does the open jobs. The sealed casings mean a cleaner floor, less lost material and a safer place to work, which adds up over a season. The scrapers and screws are built for abrasive grain, with wearing parts listed by number. The factory test-runs each machine before export packing, with a matching English manual. For a plant that has measured its dust bill, the sealed conveyor pays back. The scrapers and screws are built for abrasive grain, with wearing parts listed by number.

The clean floor is also a safer place to work. And the lost material adds up over a season.
Most conveyor problems come from machines that need specialists, and the Goldilocks line deliberately avoids that. The belt changes are straightforward, the scraper chain tensions from the outside, and the screw has a simple trough with no hidden parts. Between seasons, a good mechanic greases the bearings, checks the belt tension and the chain sag, and the plant is back up in a day. Every wearing part is listed in the manual by model number, so a replacement is ordered by number and arrives without guesswork. The bearings are standard mill parts. For a plant that cannot afford a specialist on call, the conveyor line takes care of itself with ordinary skills.

Tested Conveyors, Export Ready
The Goldilocks factory treats every conveyor as a machine, not a piece of steel. The belt is centered, the scraper chain is run in, and the screw shaft is checked for balance before the crate is closed. Each machine is test-run before export packing, with the test as part of the routine. The factory holds ISO9001:2015 certification and is recognized as a high-tech enterprise, and the same system covers the conveying line. The manual, the parts list and the export documents carry the same model number, so the buyer checks the paperwork against the crate. Shipped protected for sea freight, the conveyor arrives ready to mount. For a plant that has been burned by a cheap machine, the test is what makes the difference. The test record travels with the machine, and the paperwork matches the crate on arrival. For a plant that has been burned by a cheap machine, that record is what matters.
  • “We replaced our old open belt with a TDSP 50 and the dust level on that floor dropped the same week. The crew bolted the sections in two afternoons. The English manual showed the alignment, so no one needed to call the factory. Solid machine. The dust stayed down.”
  • “The trolley belt runs along our bin row and unloads wherever the operator drives it. We saved three short conveyors on the layout. Capacity matches the catalog, and the trolley moves smoothly. The factory confirmed the spec in writing before we paid.”
  • “I got a TLSS 200 for the bran line because the open belt kept spilling flour everywhere. The sealed trough solved it. Installed it myself in a day, cheap to run, and the bearings are standard parts. For a small mill, exactly what we needed.”
  • “We standardized on the TGSS scraper across the plant. One chain size order covers most of the line, the casings hold up to the dust, and the support has been honest from the first order. Repeat buyers get the same people on the phone.”
