Screw crushers

Screw crushers are used to process large pieces of rock to obtain a product of a specified fraction. In particular, they are designed to receive material with a maximum piece size of up to 1600 mm (with a compressive strength of no more than 180 MPa) and further crush it to a size of about 300 mm.

Their key purpose is to reduce the size of the input raw material for further technological processes (for example, feeding to conveyor transport, preparation for further finer crushing, grinding in mills, or use in production cycles). Screens ensure a stable and controlled output size of the product, which is critical for optimizing further processing stages.

• Mining industry: Main area of application. Used for crushing coal (especially with high moisture content and a tendency to stick), iron and copper ore, bauxite, limestone, phosphorite, and other soft and medium-hard rocks. They are often integrated into complexes with steep-angle conveyors for continuous transportation.
• Construction industry: Production of crushed stone and preparation of inert materials for the cement industry, road construction, and other infrastructure projects.
• Energy: Grinding coal and other solid fuels for use in thermal power plants.
• Chemical industry: Processing raw materials for the production of mineral fertilizers, soda, and other chemical products.
• Metallurgical industry: Preparation of fluxes and other auxiliary materials.

DSZ crushers stand out among other types of crushing equipment due to a number of significant advantages:

• High productivity: Ability to process significant volumes of material (reaching thousands of tons per hour), ensuring continuity of the technological process.
• Effective processing of large-sized material: DSHZ crushers are among the few crushers capable of effectively processing very large input fractions (up to 1600 mm), reducing or eliminating the need for a preliminary crushing stage.
• Minimal dust generation: The crushing process by crushing and cutting, unlike impact crushing, generates significantly less dust, which improves environmental performance and working conditions.

• Low noise and vibration levels: Due to the absence of impact loads, DSH crushers operate much more quietly, which is an important factor in maintaining safety and comfort standards in production.
• Energy efficiency: The optimized crushing principle allows for high productivity with relatively low energy consumption.
• Ability to handle problematic materials: Effectively processes wet, sticky, or clayey materials that can cause clogging and problems with other types of crushers.
• High reliability and durability: Simple and robust design, use of wear-resistant materials, and effective overload protection systems ensure long service life and minimal maintenance requirements.
