Product details
The end cover of the ball mill is a key heavy-duty accessory installed at both ends of the ball mill cylinder. Its core function is to seal the cylinder, support the dynamic load of the whole machine, connect the hollow shaft and bearing, and prevent material leakage. It is the "force core" of the ball mill.
1、 Core role
1. Heavy load support: supports the total weight of the cylinder, steel balls, and materials (up to hundreds of tons), and can withstand alternating stress.
2. Sealing and Leak Prevention: Seal both ends of the cylinder to prevent leakage of slurry, powder, and steel balls.
3. Transmission connection: The central hollow shaft is mounted on the main bearing, transmitting torque and supporting rotation.
4. Inlet and outlet channel: The inlet end cover is connected to the feeder, and the outlet end cover is equipped with a grid plate/overflow port to complete the ore discharge.
2、 Structure type (high-definition image)
1. Integral casting end cap (for small and medium-sized grinding machines)
Structure: The end cap body and hollow shaft are integrally cast and formed.
● Features: Simple structure, strong rigidity, easy installation; Large sizes are prone to casting defects.
2. Split end cap (mainstream for large and medium-sized grinding machines)
Structure: The end cover plate and hollow shaft are cast separately and connected with high-strength bolts after precision machining.
● Features: Easy to ensure casting quality, avoid stress cracks, and can be replaced separately during maintenance;
Recommendation Products
We will uphold the spirit of precision engineering, leveraging its profound technical expertise and end-to-end service capabilities as core drivers.
Working principle: Integrating mechanical, hydraulic, electrical, automation and other technologies, the horizontal shaft is driven by an electric motor to rotate, and the eccentric sleeve is driven by gears to rotate, thereby driving the dynamic cone to make circular oscillations, achieving continuous extrusion and crushing of materials. The crushing chamber is optimized in design, and the crushing effect is not affected by liner wear.
Product Name: Pressure resistant Weighing Tape Coal Feeder (NJGC/F55/SN-ICS Series) Working Principle: Fully enclosed pressure resistant shell, continuous conveyor belt; Real time measurement with weighing sensor and speed sensor, frequency conversion PID adjustment of belt speed, achieving precise quantitative coal feeding (± 0.5% measurement accuracy). Structure: Pressure resistant sealed shell, flame-retardant and heat-resistant tape, weighing bridge, variable frequency drive, automatic cleaning, high-temperature isolation gate, intelligent electronic control. parameter Output: 10-1000 t/h (commonly 50-300 t/h) Pressure resistance: -500Pa to+5000Pa (0.35MPa) Speed regulation: 0.1-1.25 m/s (variable frequency) Material: Q235 shell, tape 120-180 ℃ heat resistance. Features: fully enclosed without leakage, precise measurement, anti hot air tempering, explosion-proof, DCS remote control. Application: Thermal power plants, circulating fluidized bed boilers, large industrial coal powder boilers.
Smelting equipment (blast furnace, converter, electric furnace supporting equipment)
Core positioning: The core equipment for coarse crushing of large materials is mainly used at the front end of the crushing production line to crush large raw materials (with a maximum feed particle size of 1200mm) to ≤ 80mm, laying the foundation for subsequent crushing processes. It is an essential front-end equipment for cement and mining production lines. Working principle: Adopting the principle of squeezing and crushing, the large pieces of material falling between the fixed jaw plate and the moving jaw plate are squeezed and crushed through the reciprocating biting motion of the two jaw plates, achieving coarse crushing processing. It is divided into two types: single elbow plate and double elbow plate. The single elbow plate model has higher production capacity and is suitable for high-yield demand scenarios. Core advantages: simple structure, convenient operation, long service life of wear-resistant parts, large crushing ratio, stable output, suitable for high hardness materials (such as limestone and iron ore), low maintenance cost, suitable for various types of production lines from small to large. Adaptation scenarios: coarse crushing of raw materials in cement production lines, coarse crushing in mining, raw material crushing in sand and gravel yards, coarse crushing in construction waste recycling, etc. Corresponding images (high-definition without watermark, available for direct image search): actual photos of the entire jaw crusher, close-up shots of the jaw crusher feed inlet, jaw crusher mining site, and details of the jaw crusher transmission device.
