Small plastic hopper loader

Types of small plastic hopper loaders

A small plastic hopper loader refers to a small storage or feeding unit used to keep and feed bulk materials like pellets into machines such as extruders, grinders, or mixers. It typically has a chute or conveyor system at the bottom that dispenses the stored material into another container or machine.

Loader hoppers can be either small or large, and they typically work together with a loader to facilitate the smooth operation of machinery. When it comes to loaders, loaders can be divided into the following categories based on their service delivery systems and how they function:

• Gravity Hoppers:

Gravity hoppers are typically small storage units feeding devices that use gravity to dispense the bulk material contained within them. They are static chutes positioned at an angle, allowing the bulk material to move freely and fall into another container or machine.

• Ultrasonic Hopper:

Ultrasonic hoppers are small loader hoppers that use ultrasonic vibrations to feed bulk materials. They use a vibratory bowl system to convey the material, which is leveled by the ultrasonic screens to the discharge outlet.

• Pneumatic Hopper:

Pneumatic hoppers loaders utilize air pressure to move bulk materials from the hopper to another container or machine. They are often integrated with vacuum systems that suck in the material from the hopper and blow it out through pipelines.

• Flexible Hopper:

Flexible hoppers are adaptable and movable loaders. They are usually made of fabric or lightweight material and can be easily repositioned to different locations.

• Batching Hoppers:

Batching hoppers are loader hoppers set to dispense a specific quantity or batch of material. They are equipped with scales and control systems that precisely measure and control the amount of material being discharged.

• Tilted Hoppers:

Tilted hopper loaders have an inclined or sloped bottom surface that promotes the flow of materials. They are commonly used for feeding animals in farms, restaurants, and hotels.

Specifications and maintenance of small plastic hopper loaders

Specifications

• Capacity:

  The capacity of small plastic hopper loaders can vary depending on their specific purpose and design. Generally, these loaders have a capacity of 50kg or less. The most common sizes range from 5kg to 25kg. The loaders with smaller capacities are better suited for frequent color changes and the reverse is true for larger capacities.

• Conveyor:

  The type of conveyor a small hopper loader has affects how the loader works. Because they are flexible and easy to change, screw conveyors are frequently used. They can efficiently convey small bits of plastic. Thor conveyors are also adaptable, mainly for use with plastics. They are designed for larger volumes and can carry a lot of material at once. Pneumatic conveyors use air power to move plastic materials through tubes. They are good for long distances and quick transfers between different locations. Gravity conveyors rely on the natural pull of gravity to move materials along a slope. They are suitable for simple, low-cost systems where materials drop into the hopper by themselves. Electric-powered belt conveyors use electricity to move plastic materials on a belt. They are suitable for small loader hoppers that need continuous feeding of materials from different sources.

• Material:

  A hopper's loader material affects how strong and long it lasts. Plastic hoppers are made from many different plastic materials, each with special features. Polypropylene (PP) is a kind of plastic used to make small plastic hoppers. It is very durable, naturally resists chemicals, and withstands a wide temperature range. This makes PP a flexible and long-lasting option for different uses. Another material commonly used for plastic hoppers is polycarbonate (PC). Compared to PP, PC is crystal clear, as tough as aluminum, and has strong impact resistance. This means PC plastic hoppers can better endure physical damage and last longer. While both PP and PC are good choices for small plastic hopper loaders, they offer different benefits. The choice depends on where people use them.

Maintenance

• Regular cleaning:

  It is essential to clean the hopper loader on a regular basis. This prevents any build-up of residue from the previous material that was loaded. However, it is best to avoid using harsh chemical cleaners or abrasive brushes.

• Lubrication:

  The moving parts of the small hopper loader should be lubricated regularly. This helps to ensure easy operation and reduce any chances of excessive wear. When doing this, be sure to use a low-abrasive lubricant.

• Inspection:

  While small plastic hopper loaders are tough, they can still get damaged over time. Regular inspection helps to quickly discover any issues like cracks, leaks, or clogs. Doing periodic inspections and promptly finding any issues helps prevent bigger problems from developing.
