The maximum permissible length of protruding reinforcement before feeding it into a reinforced concrete crusher is usually 300 mm; this varies depending on the type of crusher. Exceeding this limit increases the risk of jamming and reduces throughput.
Concrete blocks with 25 mm reinforcing bars may be loaded without cutting, provided the following conditions are met: reinforcement protrusion of up to 120 mm, forklift tines of at least 180 mm, support pads of at least 40 mm, up to 3 rows, and a forklift with a capacity of at least 3 tonnes.
Mobile rotary crushers: the basic models can process rebar up to 32 mm in diameter, the medium models up to 40 mm (without modifications), and the heavy-duty models up to 50 mm. Exceeding these limits causes the rotor to jam.
A mobile crusher pays for itself more quickly than a stationary one at an annual throughput of 80,000–120,000 cubic metres, subject to variations in operating conditions, distance and raw materials.
A jaw crusher is suitable for hard basalt: choose one based on the size of the feed hopper, capacity and high-manganese steel jaws; buy from authorised manufacturers; and follow the operating instructions to ensure a long service life.
A jaw crusher is ideal for granite; it is best to purchase one from reputable manufacturers, comparing terms and conditions, checking certificates, and avoiding overpaying or making mistakes when placing an order.
Jaw crushers for quarries cost between 2 and 50 million roubles; the price depends on the specifications. It is best to buy directly from reputable manufacturers, avoiding middlemen and unverified sellers.
Stone jaw crusher: buy from official manufacturers or certified suppliers; select one based on its specifications and design features; and check the documentation and how it operates before making payment.
Jaw crushers for hard materials: the price depends on capacity and specifications, ranging from 150,000 to 1 million roubles. Avoid buying from private sellers or middlemen; it’s better value to buy directly from reputable manufacturers, who offer no mark-ups, a warranty and after-sales service.
A rock crusher is essential for the mining and construction sectors. When choosing one, take its key specifications into account, avoid common pitfalls, and look for reliable data in official documents and independent reports.
