Product features: 1. Urea crusher mainly uses the grinding and cutting of the gap between the roller and the concave plate. 2. The clearance size determines the degree of material crushing, and the drum speed and diameter can be adjustable. 3. When the urea enters the body, it hits the body wall and the baffle and is broken. Then it is ground into powder through the rack between the roller and the concave plate. 4. The clearance of the concave plate shall be adjustable to the extent of crushing by the regulating mechanism within 3-12 mm, and the feeding port regulator can control the production volume. Product introduction: Crop straw crusher can crush corn straw, straw, peanut skin, beanstalk, flowers and other burning residues. It avoided the burning of crop straw, protected the environment, and effectively developed renewable energy. The machine is reliable in operation, that easy to operate and maintenance. The equipment has a wide range of raw materials, and is suitable for crop residues. Performance characteristics: This product design is reasonable, the manufacture quality is reliable, has the structure simple, the operation is convenient, the volume is small, occupies the land little, saves the labor, saves the electricity characteristic.The designed automatic control electric heating device can adjust the dry and humidity of materials randomly, ensure the stability of discharging molding, and improve the working efficiency.The main parts of this product are made of wear-resistant material, which is specially treated, so it can be continuously pressed and durable.Suitable for all kinds of biomass raw materials (corn straw, wheat straw, cotton straw, straw, branches, leaves, sawdust and other agricultural materials as raw materials or wood. Working principle: Straw crusher can be matched by motor, diesel engine or 30-50 horsepower tractor, the main engine is composed of feeding mechanism, zha cutting mechanism, throwing mechanism, transmission mechanism, walking mechanism, protective device and rack.It has the advantages of reasonable structure, convenient movement, automatic feeding, safety and reliability. Its components are as follows: 1. Feeding mechanism: it is mainly composed of feeding platform, upper and lower cao kun, fixed blade, fixed knife support base. 2, zha cutting and throwing mechanism: mainly by the moving knife, knife disc, lock screws and other components. 3. Transmission mechanism: mainly composed of triangle belt, transmission shaft, gear, universal joint, etc. 4. Walking mechanism: mainly composed of ground casters. 5. Protective device: it is composed of protective cover.
