Custom Pellet Crumbler Machine Manufacturers

Goldlong Machinery And Engineering Co., Ltd. designs and builds pellet crumbler machines for feed mills, aquafeed plants, and fertilizer processing lines that need to convert dense pellets into a controlled crumb structure. We are the Custom Pellet Crumbler Machine Manufacturers behind this Crumbler product family, supplying single machines or complete crumbling sections from our 14,000 m² manufacturing facility in Jiangsu, China.

Our range is built around two complementary configurations: the Three Roll Crumbler and the Double-Roll Crumbler. Both are engineered for continuous operation, adjustable particle size, low noise, and straightforward maintenance.

Our Crumbler Range and Application Fit

Process and Application Fit

In a feed mill, the crumbler softens pellets that are too hard for young animals or for certain aquatic feeds. It converts whole pellets into a crumb with a defined granule distribution, which improves feed intake and reduces waste. The machine is positioned after the pellet mill and cooler, and before the rotary sifter removes fines and oversized particles.

We size the crumbler according to the upstream pellet line and the target crumb specification. The same machine family is used in fertilizer granulation and chemical processing where a controlled reduction in particle size is required without producing excessive fines.

Material, Capacity, and Critical Specifications

Selection starts with the material. Pellet diameter, hardness, moisture, fat content, and bulk density determine roll force, gap setting, and drive power. For abrasive feed ingredients and fertilizer materials, the roller shell material becomes the key reliability factor.

• Target particle size and acceptable fines ratio
• Rated throughput in tonnes per hour
• Pellet diameter range and hardness
• Moisture and fat or oil content
• Roller gap adjustment range and method: manual, mechanical, or hydraulic
• Protection requirements: hydraulic overload release, anti-jam, and safety interlock

Capacity is not solely a function of motor power. Roll width, roll speed, surface condition, and material flow characteristics all affect the result. Our proposal defines the operating point and the spare parts that should be held in stock.

Configuration, Controls, and Automation Integration

We supply crumbler machines with the control and monitoring level that matches your line. For simple installations, a local starter panel with manual gap adjustment is sufficient. For automated feed mills, we can integrate the crumbler into the line control system so that gap, motor load, and material flow are monitored continuously.

• Motorized or hydraulic gap adjustment for remote control
• Hydraulic protection system to release when foreign objects enter the rolls
• Safety interlock and protective cover for operator protection
• Interface with upstream cooler discharge and downstream rotary sifter
• Optional variable-speed feeding to stabilize material bed depth

Because we manufacture the surrounding process equipment, we can supply matching transition hoppers, support structures, and conveyors as part of the same scope.

Quality Assurance, Installation, and Acceptance

Our manufacturing facility is run under ERP management to control workshop operations and maintain stable product quality. Before shipment, each crumbler is inspected for performance, stability, safety, and full-system operation. Our R&D and engineering teams can also develop or modify machines based on customer drawings or samples.

On turnkey projects, we handle installation, commissioning, and operator training. The commissioning phase includes gap setting, no-load and load operation, and verification of particle size. After acceptance, our after-sales team provides remote diagnostics, rapid spare parts dispatch, and regular follow-up. Common wear items such as the Roller Shell and roller assembly are stocked for quick replacement.

Information We Use to Configure Your Solution

To prepare a precise configuration and quotation, we need the operating parameters of your line and the crumb specification you want to achieve. The list below is the starting point for every crumbler proposal.

• Product type and target crumb size or granule distribution
• Required capacity in tonnes per hour
• Pellet diameter, hardness, moisture, and fat content
• Upstream equipment: pellet mill, cooler, and conveying arrangement
• Downstream equipment: rotary sifter, packing, or bagging
• Available electrical supply and control interface
• Space constraints, installation height, and supporting structure
• Operating hours, maintenance strategy, and required spare parts
• Export packaging, delivery, and documentation requirements

With these details, we provide a proposal that includes the recommended crumbler model, roller configuration, motor power, gap adjustment system, dimensions, and the spare parts package.
