Leather Diaphragms for Crushers: Unmatched Durability for Extended Performance

Leather diaphragms are an excellent choice for certain crusher applications, particularly in oil-type jaw crushers, where they serve as a vital sealing element to prevent oil leakage. While rubber diaphragms are also common, leather offers a significant advantage in terms of lifespan, often lasting 3-4 times longer than rubber (neoprene) diaphragms. This extended durability translates directly into reduced downtime, lower replacement costs, and increased operational efficiency for your crushing operations.

Why Choose Leather Diaphragms?

• Exceptional Lifespan: This is the primary benefit. High-quality leather diaphragms, especially those made from treated buff leather, are engineered to withstand the demanding conditions within crushers for significantly longer periods than their rubber counterparts. This means fewer interruptions for maintenance and replacements.
• Reliable Sealing: Leather provides a consistent and effective seal for oil tanks in jaw crushers, preventing lubricant loss and contamination.
• Durability and Flexibility: Treated leather offers a unique combination of strength and flexibility, allowing it to perform reliably under pressure and movement.
• Cost-Effectiveness in the Long Run: While the initial cost might be comparable or slightly higher than rubber, the drastically extended lifespan of leather diaphragms leads to substantial savings over time due to less frequent replacements and reduced labor costs.
• Consistent Performance: Known for their stable performance over their long service life, ensuring smooth and reliable operation of your crusher.

Common Applications:

• Oil-type Jaw Crushers: Primarily used for sealing oil tanks, a critical function to maintain lubrication and prevent damage.
• Stone Crushers: Applicable in various stone crushing machinery where a durable and reliable diaphragm is required.
• Common Sizes: Available in various sizes, with examples like 12-inch, 15-inch, 18-inch, and larger rectangular diaphragms suitable for Oil type Jaw crusher Like 16x9, 20x12, 30x15, 36x8,36x24, 36x30,30x24 42x6, 42x8, 42x9,42x10,42x36, 48x36.

1. Maintain Toggle Plate Position: The spring, in conjunction with the tie rod, ensures that the toggle plate (or elbow plate) remains firmly seated against the moving jaw (pitman) and the rear frame. Without it, the pitman would "flop around."
2. Absorb and Buffer Vibration/Impact: Crushing involves immense forces and vibrations. The springs act as shock absorbers, cushioning the impact of the crushing action and reducing stress on other machine components. This helps to reduce wear and tear and extend the lifespan of the crusher.
3. Adjust Discharge Opening (in some designs): While the primary function of the tie rod and spring assembly isn't direct adjustment, it can be part of the mechanism that allows for adjustments to the discharge opening size in some jaw crusher designs. Tightening or loosening the spring's compression can affect the position of the moving jaw.
4. Safety Mechanism: In certain designs, the tie rod and spring system is designed to fail before more critical and expensive components of the crusher are damaged in the event of an uncrushable material (tramp iron) entering the crushing chamber. While the toggle plate is often the primary sacrificial part for this, the spring system can also play a role in absorbing excessive load.
