Kymaster produces highquality spare parts for biomass grinders.

1. Hammers

Hammers are the core working components of the grinder, and it is of great importance to select highquality spare parts.

The rotor of the biomass machinery drives the hammers to rotate at a high speed, continuously crushing the materials to make them finely ground.

The hammers produced and wholesaled by Kymaster are made of highhardness alloy steel, such as those containing chromium and molybdenum alloy elements (the surface hardness can reach HRC55 62), and they also have good toughness.

The hammers produced by Kymaster adopt a symmetrical structure, and the cutting edges are exceptionally wearresistant after special treatment.

The wear amount after continuous operation for 1,000 hours is lower than that of similar products on the market.

2. Screens

Function: Screens are the key components for ensuring uniform crushing of biomass materials and directly affect the output of the materials.

The screens produced and wholesaled by Kymaster are made of highstrength 304 or 316 stainless steel, which is corrosionresistant and fatigueresistant, reducing the frequency of spare parts replacement.

The screens produced by Kymaster have high precision in the screen holes, a reasonable hole opening rate, a flat screen surface, and no broken wires or burrs, and there will be no tearing during use.

3. Rotor

Function: The rotor is the power component that drives the hammers to rotate at a high speed.

The rotors produced by Kymaster adopt an integral forging process, and the dynamic balance accuracy reaches a relatively high standard in the industry.

When rotating at a high speed, the vibration value of this rotor is controlled within a low range, and it rotates flexibly, maintaining good performance even in harsh working environments.

4. Main shaft

The main shaft bears the torque, bending moment generated by the rotation of the rotor and hammers, as well as the impact force of the biomass materials.

The main shafts produced by Kymaster are made of highpurity and highstrength 40Cr or 42CrMo alloy steel. After quenching and tempering treatment, the yield strength and tensile strength reach excellent levels.
