Jaw Crusher - 250 MM

Application:

TESTFORM Laboratory Jaw Crushers engineered for pre-crushing of extremely hard up to brittle materials. The 250 x 400 Jaw Crusher is designed for batch and continuous crushing of middle hard, hard brittle, and tough materials for the following fine grinding.

This Crusher will crush

• Minerals / ores / slags
• Cement/cement clinker/concrete
• Glass / ceramics / corundum
• Soil samples/sludges
• Coal/coke/drill core
• Industrial waste

A jaw crusher robustly constructed double-toggle type with double moving jaw plate. It is robust and long-wearing and made of parts and materials easily serviced in a remote areas.

The crusher is supplied as a free-standing floor-mounted unit with the motor to the front of the main body.

Comes complete with a dust extraction point (from the top of the machine) and a removable sample bucket.

Principle of operation of this crusher

TModel MN012 has 250mm X 400mm Jaws; It is used by laboratories and processing companies to break up solid materials such as rock or soil and ores.

The material to be processed falls into the crushing chamber of the 250 mm X 365 mm Crusher via a guide chute and is crushed by crushing the action of a static and dynamic jaw plate until it passes the preselected gap of the crusher.

The steples gap setting can be adjusted via a hand wheel and an mm scale from 0 mm to 50 mm (contact of the jaw plates).

This adjustment setting enables the operator to also perform a zero-point calibration setting to adjust the crusher.           

Easy cleaning and operation:

No other Laboratory Jaw Crusher is easier to clean than the TESTFORM Jaw Crusher. When the crushing process is finished the infeed hopper cover and front door can be opened in a second. Due to these points, the crushing chamber is fully accessible for quick and easy cleaning in order to perform a fast and systematic cleaning of the grinding tools.

Jaw plates/side liners material compositions:

• Manganese steel
• Tungsten carbide

Crusher Gap adjustment:

The required gap setting can be comfortably and reproducibly adjusted by rotating the handwheel. The gap setting can therefore steplessly pre-chosen according to a scale prior to starting the crushing process.
