Large Crushers
Delumper L–series crushers process a wide range of materials, including chemicals, foods, minerals, plastics, and pharmaceuticals. The Delumper 2020L is a larger, more powerful unit with higher capacity. With its larger throat opening, this unit easily processes greater volumes of agglomerates and lumps to a free-flow condition. Its body features seamless stainless-steel construction, a 20 × 20 in. inlet and discharge opening, and wide mounting flanges for easy connection to systems or hoppers. It has specially designed teeth mounted on a smooth rotating drum that intermeshes with sizing combs. Solids are reduced to their basic grain size without overgrind, heat rise, or fines. Lumps up to the full inlet opening size can be processed. The unit runs at a low speed and creates little vibration or noise.

Combination Attritor with Vertical Shaft Adjustment
This hybrid laboratory mill has a vertical shaft adjustment function that combines features of the company’s HSA-1 and 1-S model attritors. The vertical shaft adjustment feature is designed to accommodate grinding media of different sizes, making the combination mill more versatile. While this feature is typically included on the 1-S attritor, it has not been included previously on the HSA-1 model. The drive system allows the user to switch easily between the high-speed 1700-rpm HSA system with side discharge and the conventional 350-rpm 1-S system with bottom discharge. The HSA tank cover has a two-piece stainless-steel design with a brush seal, charging chute, and vent. The 1-S tank cover is a one-piece nylon-coated stainless-steel cover with a charging port and brush seal for dust control.
