jaw crusher V-Belt

V-belts, critical flexible drives in jaw crushers, transmit power between motor and eccentric shaft pulleys via friction, featuring shock absorption and overload protection. Composed of a tensile layer (polyester cords/aramid), top/bottom rubber (60–70 Shore A hardness), and a cover fabric, they adopt a trapezoidal cross-section (e.g., SPB type) for pulley groove compatibility. Manufacturing involves rubber mixing (120–150°C), belt blank winding, vulcanization (140–160°C, 1.5–2.5 MPa), and post-stretching. Quality control includes testing tensile strength (≥10 kN for SPB), friction coefficient (≥0.8), and dimensional accuracy (length deviation ±0.5%). With a 3000–5000-hour service life, they require proper tensioning and simultaneous replacement of belt sets to ensure stable crusher operation

Jaw Crusher Toggle Plates

**Abstract** The jaw crusher toggle plate (thrust plate) is a critical force-transmitting and overload protection component, typically made of gray cast iron (HT200/HT250) or malleable cast iron (KT350-10). Structurally, it consists of a body, support ends, reinforcing ribs (if applicable), and weakening grooves (for controlled fracture). Its manufacturing involves sand casting (with melting at 1380–1420°C, heat treatment for stress relief), machining (precision finishing of support ends and weakening grooves to ensure fit accuracy), and strict quality control (material composition checks, MT for cracks, dimensional inspections, and strength testing of weakening grooves). Functioning to transmit force and protect the crusher from overload by fracturing when overloaded, it ensures operational safety with a 3–6 month service life.

jaw crusher Hydraulic System

The hydraulic system in jaw crushers, critical for adjusting discharge gaps and overload protection, comprises power sources (hydraulic pumps, motors), actuators (adjustment/safety cylinders), control components (valves, pressure transducers), auxiliaries (pipes, filters), and L-HM 46# hydraulic oil, operating at 16–25 MPa. Core cylinder manufacturing involves precision boring (Ra≤0.8 μm), chrome-plated piston rods (50–55 HRC), and assembly with strict sealing. Quality control includes pressure testing (1.5× working pressure), oil cleanliness (≤NAS 7), and performance checks (overload relief in 0.5s). With MTBF ≥3000 hours under proper maintenance (oil replacement every 2000 hours), it ensures efficient, safe crusher operation via rapid response and stable pressure control.

Jaw crusher electrical control system

The electrical control system of jaw crushers, as the "nerve center," manages motor operation, monitors status, and enables overload protection via PLC-based automation. It comprises power circuits (breakers, contactors), control systems (PLC, relays), monitoring components (temperature/vibration sensors), and an HMI (touch screen, control cabinet). Manufacturing involves component selection (IP65 sensors, derated devices), cabinet fabrication (IP54, powder-coated steel), precision wiring (shielded cables, crimped terminals), and PLC/HMI programming. Quality control includes insulation tests (≥10 MΩ), EMC compliance, and 100-hour runtime validation. With MTBF ≥5000 hours under regular maintenance (sensor calibration, dust cleaning), it ensures safe, efficient crusher operation through real-time monitoring and responsive contro

HPGR Crusher Studs

Studs are key wear-resistant components on High-Pressure Grinding Rolls (HPGR), typically made of high-hardness alloys (e.g., high-chromium cast iron, tungsten carbide) to enhance crushing efficiency and protect roll surfaces. Their manufacturing process involves material selection (with chemical composition verification), forming (casting for high-chromium alloys or powder metallurgy for tungsten carbide), heat treatment (quenching/tempering or stress-relief annealing), and surface treatment (anti-corrosion coatings, polishing).

High Pressure Grinding Rolls studs

- Raise the left and right frames on both sides of the extrusion roll of the high-pressure grinding roll symmetrically with the left and right sleepers to ensure sufficient height for the extrusion roll to operate without damaging the mechanical assembly joint surface under the frame; - Rotate the position on the shaft shoulder on one side of the extrusion roll where the stud needs to be replaced to the horizontal position. Use the magnetic drill fixed on the left frame to drill a stud hole at this position by operating the handle with a drill bit; - Then aim the fixed long baking gun at the stud hole for heating from the inside to the outside. When the stud hole and the surrounding area are heated to a red-hot surface close to the oxidized state, apply qj102 silver brazing flux and inlay the matching stud into the stud hole so that the surface height of the stud is equal to the height of the existing used stud;
