Spring Cone Crusher for Mining, Quarrying and Hard Rock Crushing
Spring Cone Crusher for Mining, Quarrying and Hard Rock Crushing
STM Spring Cone Crusher is a reliable cone crushing machine designed for crushing medium and high-hardness minerals and rocks in mining, quarrying, metallurgy, construction, road building, chemical and silicate industries.
With a robust structure, spring overload protection system, convenient discharge adjustment and multiple crushing cavity configurations, the spring cone crusher can be used for secondary and tertiary crushing according to different production requirements.
The European Type Grinding Mill (MTW Series) manufactured by Henan Centbro Machinery Equipment Co., Ltd. (STM Machinery) is an advanced, high-efficiency industrial powder processing machine engineered for non-flammable and non-explosive mineral grinding.
Incorporating heavy-duty bevel gear drive technology, curved air ducts, and an internal thin-oil lubrication system, this modern replacement for traditional Raymond mills achieves high throughput, low energy consumption, and precise fineness control across non-metallic mineral, desulfurization, and chemical processing lines.
Technical Features & Performance Highlights
Understanding the European mill working principle helps operators optimize fine powder production. Material fed into the grinding chamber is crushed between high-speed rotating grinding rollers and rings, while the air stream carries ground particles up to the high-efficiency classifier for continuous separation:
1. Bevel Gear Integral Drive System
Utilizing an integrated bevel gear transmission system instead of traditional belt/reducer drives, the mill achieves up to 98% transmission efficiency. This compact design reduces mechanical energy loss, cuts power consumption by 20% to 30%, and lowers total installation costs.
2. Internal Thin-Oil Lubrication & Extended Wear Life
Unlike traditional grease-lubricated mills requiring frequent downtime for maintenance, the internal oil pump system delivers continuous lubrication directly to main shaft and bevel gear bearings. Combined with high-manganese alloy wear parts (Mn18Cr2) and replaceable shovel blade tips, component service life is extended by up to 30%.
3. Resistance-Free Curved Air Duct & Volute Design
The smooth, arc-shaped tangential air inlet minimizes air resistance and eddy current turbulence. This optimized airflow design prevents duct blockages, ensures smooth material pneumatic conveying, and lowers fan power requirements.
4. Eco-Friendly Negative-Pressure Pulse Dust Collection
Equipped with an automated pulse jet dust collector and operating under continuous negative pressure, dust emissions remain well below strict international environmental limits, supporting eco-friendly grinding circuit setups.
