  • what are the differences between your elevator buckets and your competitor's buckets?

    • The key difference between our buckets and the competition is in the bucket design and variations that we offer to our customers.
    • Prime offer over 12 different design styles of buckets in different types of polymer materials such as NYLON, HDPE, and POLYURETHANE, we also offer a range of pressed and fabricated buckets in Mild Steel and stainless steel to suit different industries and applications.
    • We increase the thickness of our buckets in areas that are critical due to wear. These include areas such as the leading front lip, back wall where fastening to the elevator belts is critical and the reinforcing ribs of the buckets. In non-wearing areas of the buckets we reduce material usage thus providing extended bucket life without increasing the weight.
  • What materials are available for your plastic elevator buckets ?

    • There are 3 types of materials that we use for the manufacture of our elevator buckets they are HDPE, NYLON & PU.
    • HDPE buckets: suitable for handling grains, foodstuffs, and other products without sharp edges and with bulk densities of less than 1g/cm3. HDPE buckets are NOT suitable for materials with service temperatures over 80℃.
    • Nylon buckets: suitable for handling highly abrasive products at elevated temperatures. Nylon is highly recommended for use in rough or severe service elevators. NYLON buckets are NOT suitable for materials with a service over 120℃.
    • PU buckets: suitable for handling extremely abrasive material. They’re an excellent choice for extremely high throughput elevators. Correct choice of bucket material will reduce downtime of your conveyor system and and save money in the long run.
  • How many types of buckets are available ?

    • We have both Agricultural Buckets and Industrial Buckets. 15 bucket types and more than 250 models are available.
    • Agricultural buckets: suitable for grains, feeds, food products, seeds, fertilizers, salt and chemicals.
      Industrial buckets: suitable for ores, sand, gravels, coal, fertilizer, clay, salt, limestone and cement.
    • D Type: Deep bottom bucket for agricultural use. Heavy-duty buckets suitable for handling grains, feeds, fertilizers, seeds, salt and chemicals, etc.
    • S Type: Shallow bottom bucket for agricultural use. By allowing closer bucket spacing on the belt, it improves the elevator capacity. It’s suitable for higher discharge speed and light material elevating.
    • EU type: European Low Profile bucket for agricultural use. It changes the material of traditional European low profile steel bucket to plastics in order to meet variety customers’ needs.
    • M Type: Medium bottom bucket for agricultural use. It changes the material of traditional European medium steel bucket to plastics in order to meet variety customers’ needs.
    • DS Type: Deep bottom bucket for agricultural use. It’s our first generation of plastic deep bottom elevator buckets and can interchange with D type and CC type buckets .
    • DQ Type: Shallow bottom bucket for agricultural use. It’s our first generation of plastic shallow bottom elevator buckets and can interchange with S type and EU type buckets .
    • DW Type: Bottomless Bucket for agricultural use. Several bottomless bucket and one bucket consists of one group and must be installed at a very close spacing on the belt to achieve larger capacity. Capacity will increase 1.5~2 times by replacing the original buckets with bottomless buckets in the elevators. Also, bottomless bucket is suitable for higher discharge speed. Power needs to be changed while the capacity of the elevators are increased by using DW bottom bucket.
    • DG Type: Combination bucket for agricultural use. It’s a special design by composing one bottomless bucket and one general bucket. With improved capacity, it suits for high discharge speed.
    • DM Type: Continuous Discharge bucket for Agricultural use. It’s suitable for low-speed discharge elevator at 0.5~0.8m/s. The products are fed into the bucket slowly. When the buckets move onto the elevator head for discharging, the products fall to the previous bucket’s slide bottom first, then flow into the outlet of the elevator. The products are handled slowly and gently, thereby to reduce the broken percentage of products in the process of elevating. It’s recommended for the industry where low broken percentage is required.
    • DH Type: As agricultural bucket, it’s suitable for drying elevator in the paddy and rice handling industry, as well as for other agricultural applications.
    • DL Type: Overlapping bucket for agricultural use. It’s specially designed for chain conveyors mixed by vertical and horizontal transmission. The loading and discharge processes are finished by free falling of the products. This bucket is mainly used for high demand on low broken percentage and applications on difficult loading and discharging. Almost no wear loss during loading and discharging processes, so good overturning and size stability in the full loading should be guaranteed in the elevator running. Therefore, well rigid material is preferred for this bucket .
    • AA Type: AA industrial bucket made of Nylon. It’s an updated model of traditional cast iron bucket with thicker front lip and reinforced bolt installation area. It’s suitable for ore, sand, gravel, coal, fertilizer, clay, salt, limestone and cement, etc. AA bucket is the optimum choice of industrial bucket.
  • Do you manufacture steel elevator buckets ?

    • Yes we manufacture and supply steel buckets. They’re available in Mild and Stainless Steel. Now we have 2 types of bucket design: SM Type and SS Type. We also offer fabricated steel buckets in carbon steel and stainless steel.
  • How do I measure bucket dimension and capacity ?

    Measuring Bucket Dimension:

    measure_bucket

    Measuring Bucket Capacity:

    • Measure Bucket Capacity is quite simple, all you need to do is to fill the buckets with water to get the correct volume. 1 litre of Water Volume is the same as 1kg in weight then just multiply by the specific gravity of the product being transferred to get an accurate calculation.
  • Why do your buckets need venting ?

    • A venting bucket can improve the efficiency of some bucket elevators when handling certain products. On dense materials such as flour, meals, and mash feeds, the vents allow air to escape through the cup as it fills, which permit the cup to fill more completely. During discharge, air can return through the cups as it empties, thus preventing a vacuum that could hold some of the product in the cup and cause backlegging.
    • On extremely light materials such as alfalfa meal, screenings and bran, a vented bucket not only minimizes blowing of the product during loading and discharge, but also reduces air turbulence in the leg as the bucket travels empty down the return side of the elevator. A reduction in air currents minimizes the vacuum which can draw a light product through the down leg and back to the boot.
    • We have four standard patterns available which offer varying amounts of air release for the handling of most products. Custom venting is available upon request.
  • What's the applications for steel buckets ?

    • Steel buckets can be used in 2 different ways. They can be used in applications where products and service temperature exceed the service temperature of our plastic buckets, or where heavy products or sharp products are likely to be elevated. The other side they can be used as a digger bucket in conjunction with our plastic buckets where poor flowing or easily compacted materials are conveyed.
  • Can we reduce the Bucket Spacing for your elevator buckets ?

    • Bucket spacing can be reduced, however consideration needs to be given to head and tail pulley sizes, elevator speed and type of products being handled. These should all be assessed in accordance with each individual application.
    • Belt width recommendations for mounting buckets should be 20mm wider per side than the installed bucket length.
  • Are your buckets stackable and easy to pack and transport ?

    • All of our plastic buckets are designed to nest together for a smaller transport space to save your transport cost.
  • What about your elevator bolts & belt fasteners ?

    • All our elevator bolts and fasteners are produced in house delivering high quality products consistently.

Impact Bar

  • What are the features of our impact bars ?

    • Stock available for immediate delivery.
    • Different sizes available covering your needs and applications.
    • Flame Retardant Impact Bars are “flame resistant & anti-static”, suitable for underground coal mining applications.
    • Shock absorbing rubber structure provides maximum impact resistant.
    • The UHMWPE surface of impact bar gives extremely low coefficient of friction hence reduces the wear on the conveyor belt. UHMWPE also has a good wear resistant property.
    • The “T-slot” metal construction allows fixing of the impact bar along the entire length of the bar as well as easy installation.
  • which is better on buffering effect between impact bar and rubber conveyor roller.

    • The contact between impact bar and conveyor belt along length-wise and width-wise is an area contact, it solidly supports position on belt impacted by loading. But contact between rubber conveyor roller and belt is line contact, besides distance between 2 contact line is bigger than 1 single roller diameter so that the supporting is not solid and can not guarantee good buffering effect on belt. Therefore impact bar has much better buffering effect on belt than rubber roller.
    • The force on belt will be pressed evenly on impact bar surface, effectively reduce phenomenon of splashing and scattering compare with using rubber roller.
    • UHMWPE board with super low coefficient smooth surface can reduce friction with belt as most as possible. Special rubber ply with high elasticity can absorb impact from conveying materials as most as possible. The parts of impact bar combined by vulcanized technology that can make joint more solid and durable.
    • There are bolts along length-wise that can firmly fix T-track on impact bed frame to get guarantee of solid joint, it is also very easy to dismantle or remove when need.
  • What applications are for Normal Impact Bar, High Elastic Impact Bar & Flame Resistant Impact Bar ?

    • Normal Type: Suitalbe for general use except for underground coal mine.
    • High Elastic Type: Suitable for the conveyor loading points with high falling head where request better buffering property.
    • Flame Retardant Type: with quality approval on the “Flame Resistant & Anti-static” ability for underground coal mine industry. However, the elasticity and abrasive resistance will be less than other types.
