CHOPPER

The grinder reduces the specific size of the particles that make up the feed, minimizing fine dust. This is a specially designed pellet mill for flour grinding, oilseed processing and biomass production.
The La Meccanica grinder is a very robust machine that allows you to obtain a particularly homogeneous and regular granulometry of the crushed products. The rollers are adjustable and mounted on a spring to protect against damage that can be caused by foreign objects.

  • solid construction
  • cutting rollers are adjustable and mounted on springs to protect against damage that can be caused by foreign objects
  • roller diameter: 220 mm
  • roller length: 1200-1800 mm
  • motor from 7.5 to 15 kW, 1450 rpm, IP 54, insulation class F
  • roller gap can vary from 0 mm to 3 mm
  • transmission between the motor and the fixed rollers is carried out by means of a belt drive
  • 20 mm is the maximum size of a pebble or foreign object passing through the grinder
  • the grinder has a bypass, which is controlled by a pneumatic piston

Shredder with remote control roller gap

  • roller gap can be adjusted by servo

Optional

The rollers are adjusted by a hydraulic piston driven by a hydraulic device located outside the machine and controlled from the control panel.

The position of the rollers is calculated by means of an angular potentiometer mounted behind the rollers (inside the main shaft). The potentiometer signals the angular position of the roller pins. By operating the entire system from the control panel, the distance between the rollers and the die can be calculated using the signal transmitted by the potentiometer.

At the electronic panel, the operator chooses the roller position. The panel pressurizes the hydraulic circuit and moves the piston until the rollers reach the desired position.

From the electrical panel, the operator determines the position of the rollers by applying pressure to the hydraulic system and moving the piston until the rollers reach the desired position. Once the desired position has been reached, the system is locked and held in position by two valves.

The maximum pressure reached by the hydraulic system is 250 bar, and the required pressure for moving the piston and adjusting the rollers is 150 bar.

The adjustment is done quite quickly: you can move the rollers closer or further away from the matrix by 7-8 mm, in each direction in about 15 seconds.

The device allows replacing the matrix in 10-20 minutes, depending on its size. The system includes a tapered stainless steel ring that is closed and held in place by Belleville disc springs.

This ring locks the die in place. The matrix is released by pressure on the hydraulic system, which pushes the springs to release the elastic ring.

For more information, watch the following video: Rapid Block System

The system consists of a hand pump and a piston, which are needed to dismantle the die.

The piston is installed between the rotor and the reinforcement flange so as to push the die out of its seat.

This system includes a high viscosity grease pump.

It is equipped with blades to break up possible air bubbles. The system is connected to the press via a rotary distributor connected directly to the main shaft.

Lubrication is controlled by an electrical panel that is included in the delivery. The panel allows you to measure the required amount of grease using two timers to regulate the time for applying grease and pause.

 

The pump has the following characteristics:

● the flow is adjustable from 2.9 to 17 cc / min.

● motor 0.185 kW, 400V, 50Hz

● steel tank for 10 kg

● filter

● pressure relief valve

● pressure gauge

● indicator of minimum lubricant level

● progressive dispenser for distributing grease at two points

● inductive PNP sensor for cycle monitoring

● control valves for 1/8 outlet
